Description

BACKGROUND

Technical Field

The present invention relates to a display device and, more specifically, to a display device having a shaped sealing member.

Discussion of the Related Art

Display devices may be applied to portable electronics such as smart phones, smart watches, tablet PCs, and notebook computers, or large electronic devices such as televisions, monitors, and digital information displays.

Recently, display devices have been designed to have a slimmer bezel so as to provide electronic devices with a wider screen without increasing the size of the electronic device.

As display devices are often used in portable electronics, such as smartphones, in which a speaker module and one or more optical sensors are disposed, one method for reducing bezel size is to create a display device having a display area that is atypically shaped to have a notch or trench shape in a top region thereof. However, when the display area is atypically formed, the durability of the display device may deteriorate.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the attached drawings.

FIG. 1 is an exploded perspective view illustrating a display device 1 according to an exemplary embodiment of the present invention. FIG. 2 is a cross-sectional view illustrating the display device 1 of FIG. 1, taken along line II-II′ in FIG. 1. FIG. 3 is a cross-sectional view illustrating the display device 1 of FIG. 1, taken along line III-III′ in FIG. 1. FIG. 4 is a plan view illustrating a first base substrate 111 of a light-emitting substrate 101 of FIG. 1. FIG. 5 is a plan view illustrating a second base substrate 211 of a counter substrate 201 of FIG. 1.

Referring to FIGS. 1 to 5, in the display device 1 according to an exemplary embodiment of the present invention, a display area DA and a non-display area NA (See, for example, FIG. 2) may be defined.

The display area DA may include a plurality of pixels and may provide image display. As used herein, the term “pixel” refers to a smallest unit area for generating a point of color. Each pixel may express a predetermined basic color. Examples of the basic color may include, but are not limited to, red, green, and blue. In an exemplary embodiment of the present invention, in a plan view, the display area DA may have a shape in which one side edge (for example, a lower edge in FIG. 4) is partially indented. For example, one side edge of the display area DA in the second direction Y may have an atypical shape such as a bay, a notch, or a trench, in a plan view.

In a plan view, the display area DA may be at least partially surrounded by the non-display area NA. The non-display area NA refers to an area not contributing to image display. The non-display area NA may include a sealing area SA in which a sealing member 301 is disposed, an inner non-display area INA located inward from the sealing area SA (e.g., between the display area DA and the sealing area SA), and an outer non-display area ONA located outward from the sealing area SA.

In an exemplary embodiment of the present invention, the display device 1 includes a light-emitting substrate 101, a counter substrate 201 disposed over the light-emitting substrate 101, and a sealing member 301 disposed between the light-emitting substrate 101 and the counter substrate 201 and coupling the light-emitting substrate 101, and the counter substrate 201. The display device 1 may further include a first flexible circuit film 401, a second flexible circuit film 501, and a module member 601.

The light-emitting substrate 101 (for example, a first substrate) may include a light-emitting element 190 capable of emitting light by itself to provide light necessary for image display. For example, the light-emitting substrate 101 may be a display substrate including the light emitting elements 190 disposed at each pixel. The light emitting elements 190 disposed at each pixel may emit light independently of each other, thereby implementing image display and color expression.

The first base substrate 111 may provide a space for stably disposing the light emitting element 190 and the like. The upper surface of the first base substrate 111 may be placed in a plane to which the first direction X and the second direction Y belong. The first base substrate 111 may be a transparent or opaque insulating plate or insulating film. For example, the first base substrate 111 may include a glass material, a quartz material, or the like. For example, the first base substrate 111 may include a polymer material such as an imide resin, a carbonate resin, and/or an acrylic resin.

In an exemplary embodiment of the present invention, in a plan view, the first base substrate 111 may include a main portion 111a (see, FIG. 4) having a first maximum width W_111a in the first direction X, a first protruding portion 111b protruding from the main portion 111a in the second direction Y, and a second protruding portion 111c protruding from the main portion 111a in the second direction Y and spaced apart from the first protruding portion 111b in the first direction X. The first protruding portion 111b of the first base substrate 111 may have a second maximum width W_111b in the first direction X, and the second protruding portion 111c thereof may have a third maximum width W_111b in the first direction X. Each of the second maximum width W_111b and the third maximum width W_111b may be smaller than the first maximum width W_111a. For example, the sum of the second maximum width W_111b and the third maximum width W_111c may be smaller than the first maximum width W_111a. The second maximum width W_111b and the third maximum width W_111c of the first base substrate 111 may be the same as or different from each other. In addition, the first base substrate 111 may have a shape in which the maximum length thereof in the second direction Y is longer than the length thereof in the first direction X, for example, the first maximum width W_111a.

At least a part of the display area DA of the display device 1 may overlap the first protruding portion 111b and second protruding portion 111c of the first base substrate 111. For example, pixels are defined in the first protruding portion 111b and second protruding portion 111c of the first base substrate 111 as well as in the main portion 111a of the first base substrate 111, and each of these three portions may contribute to image display and color expression. While the display area DA is not formed to overlap the module member 601, the display area DA is formed adjacent to the module member 601 along three sides thereof (two sides in the first direction X and 1 side in the second direction Y), thereby minimizing the planar area of the non-display area NA and increasing the planar area of the display area DA.

One side edge (for example, a lower edge in FIG. 4) of the display area DA in the second direction Y may have an atypical shape such as a bay, a notch, or a trench, in a plan view. For example, one side edge 121 of the first base substrate 111 may be partially indented. For example, one side edge 121 of the first base substrate 111 may include a first edge 121b, a second edge 121a indented from the first edge 121b, and a third edge 121c protruding from the second edge 121a.

The first edge 121b refers to one side edge of the first protruding portion 111b of the first base substrate 111 in the second direction Y, the second edge 121a refers to one side edge of the main portion 111a of the first base substrate 111 in the second direction Y, and the third edge 121c refers to one side edge of the second protruding portion 111c of the first base substrate 111 in the second direction Y. The first protruding portion 111b, second protrusion portion 111c and second edge 121a of the first base substrate 111 may together form a bay.

In an exemplary embodiment of the present invention, the shortest distance D₁ from the first edge 121b to the display area DA in the second direction Y may be larger than the shortest distance D₂ from the second edge 121a to the display area DA in the second direction Y. Further, the shortest distance from the third edge 121c to the display area DA in the second direction Y may be larger than the shortest distance D₂ from the second edge 121a to the display area DA in the second direction Y.

As will be described later, the shortest distance D₁ from the first edge 121b to the display area DA is larger than the shortest distance D₂ from the second edge 121a to the display area DA, thereby sufficiently securing the width of a portion extending in the first direction X (for example, a first linear portion 311 to be described later) of the sealing member 301 disposed on the first protruding portion 111b. Further, a light-emitting substrate pad unit 170 is not disposed between the second edge 121a and the sealing member 301, thereby securing a space for disposing the module member 601 between the first protruding portion 111b and second protruding 111c of the first base substrate 111.

A driving layer including a thin film transistor 130, wirings 150, and a light-emitting substrate pad unit 170 may be disposed on the first base substrate 111. For convenience of explanation, although FIG. 2 and the like show one thin film transistor 130, in some exemplary embodiments of the present invention, the driving layer may further include a plurality of thin film transistors and/or auxiliary electrodes for forming a capacitor or a bridge.

The thin film transistor 130 may be electrically connected to the light-emitting element 190. For example, the thin film transistor 130 may be a driving transistor configured to control the amount of current provided to the light-emitting element 190 in a specific pixel. However, the present invention is not limited thereto, and the thin film transistor 130 may be a switching transistor configured to control a specific pixel to be on or off, a compensation transistor for compensating a driving signal, an initialization transistor in which an initializing signal is applied to a gate electrode, or a light emission control transistor in which a light emission control signal is applied to a gate electrode.

The thin film transistor 130 may include an active layer 131 for forming a channel, a gate electrode 135 which is a control terminal, a source electrode 137 which is an input terminal, and a drain electrode 139 which is an output terminal.

The active layer 131 may be disposed on the first base substrate 111. Although FIG. 2 and the like show a case where the active layer 131 is directly disposed on the first base substrate, alternatively, at least one inorganic layer may be disposed between the first base substrate 111 and the active layer 131. The active layer 131 may include a semiconductor material. For example, the active layer 131 may include polycrystalline silicon, or may include an oxide semiconductor.

The gate electrode 135 may be disposed on the active layer 131. The gate electrode 135 may at least partially overlap the channel region of the active layer 131 in the third direction Z. The gate electrode 135 may include aluminum, molybdenum, copper, titanium, and/or an alloy thereof. The gate electrode 135 may be formed of a single layer, or may have a laminate structure including a plurality of layers. The gate electrode 135 may constitute a control terminal configured to carry a control signal of the thin film transistor 130. In an exemplary embodiment of the present invention in which the thin film transistor 130 is a driving transistor, the gate electrode 135 may be electrically connected to an output terminal of a switching transistor for controlling a specific pixel to be on or off. A first insulating layer 140 is interposed between the active layer 131 and the gate electrode 135 to insulate them from each other. The first insulating layer 140 may be a gate insulating layer. The first insulating layer 140 may include an inorganic insulating material. The inorganic insulating material may include silicon nitride, silicon oxide, silicon oxynitride, and/or silicon oxynitride.

The source electrode 137 and the drain electrode 139 may be disposed on the gate electrode 135. The source electrode 137 and the drain electrode 139 are electrically connected to the source region and the drain region of the active layer 131, respectively, and may be spaced apart from each other. Each of the source electrode 137 and the drain electrode 139 may include aluminum, molybdenum, copper, titanium, and/or an alloy thereof. Each of the source electrode 137 and the drain electrode 139 may be formed of a single layer or may have a laminate structure including a plurality of layers. The source electrode 137 may constitute an input terminal to which the input signal of the thin film transistor 130 is applied, and the drain electrode 139 may constitute an output terminal to which the output signal of the thin film transistor 130 is applied. In an exemplary embodiment of the present disclosure in which the thin film transistor 130 is a driving transistor, the source electrode 137 may be electrically connected to a driving voltage wiring configured to carry a driving voltage, and the drain electrode 139 may be electrically connected to the anode 191 of the light-emitting element 190.

An interlayer insulating layer 160 including a second insulating layer 161 and a third insulating layer 163 may be interposed between the gate electrode 135 and the source electrode 137 and between the gate electrode 135 and the drain electrode 139. The interlayer insulating layer 160 may isolate the gate electrode 135, the source electrode 137, the drain electrode 139, and auxiliary electrodes from each other. Each of the second insulating layer 161 and the third insulating layer 163 may include an inorganic insulating material. The inorganic insulating material may include silicon nitride, silicon oxide, silicon oxynitride, and/or silicon oxynitride.

A protective layer 181 may be disposed on the source electrode 137 and the drain electrode 139. The protective layer 181 may cover the source electrode 137 and the drain electrode 139 to prevent the source electrode 137 and the drain electrode 139 from coming into contact with an organic material.

The wirings 150 may be located at least partially in the non-display area NA, for example, the outer non-display area ONA. The wirings 150 may extend from the non-display area NA to the display area DA to transmit a signal provided from an external driving element to the thin film transistor 130 or the like. For example, the wirings 150 may be electrically connected to the light-emitting substrate pad unit 170 to transmit a signal provided from the first flexible circuit film 401 to the thin film transistor 130 or the like. The wirings 150 may include a scan wiring configured to carry a scan signal, a data wiring configured to carry a data signal, and a drive voltage wiring configured to carry a drive voltage. FIG. 2 and the like illustrate a case where the wirings 150 are disposed on the same layer as the source electrode 137 and the drain electrode 139, but the present invention is not limited thereto.

The light-emitting substrate pad unit 170 (for example, a first pad unit) may be disposed in the non-display area NA. For example, the light-emitting substrate pad unit 170 may be disposed entirely within the outer non-display area ONA. In this case, the wirings 150 electrically connected to the light-emitting substrate pad unit 170 may be arranged to cross the sealing area SA. In some exemplary embodiments of the present invention, the light-emitting substrate pad unit 170 may include a pad electrode. The pad electrode has an expanded area, and may be electrically connected to the wirings 150 through a contact hole formed in the protective layer 181. However, the present invention is not limited thereto, and alternatively, the ends of the wirings 150 may extend to form the light-emitting substrate pad unit 170 for electrical connection.

Further, the light-emitting substrate pad unit 170 may be disposed adjacent to one side edge 121 of the first base substrate 111 in the second direction Y. In an exemplary embodiment of the present invention, the light-emitting substrate pad unit 170 is disposed adjacent to the first edge 121b and the third edge 121c of the first base substrate 111, but might not be disposed adjacent to the second edge 121a. For example, in a plan view, the light-emitting substrate pad unit 170 is disposed between the first edge 121b and the sealing member 301 and between the third edge 121c and the sealing member 301, but might not be disposed between the second edge 121a and the sealing member 301. The light-emitting substrate pad unit 170 is disposed on the first protruding portion 111b and the second protruding portion 111c of the first base substrate 111, but is not disposed on the main portion 111a, thereby minimizing the shortest distance D2 from the second edge 121a to the display area DA and reducing the area of the non-display area NA. In addition, a space for disposing a module member 601 is accordingly provided.

A step compensating layer 183 may be disposed on the wiring layer. The step compensating layer 183 has a step compensating function for at least partially compensating the step formed by the driving layer including the thin film transistor 130 and the like, and may provide a space for stably disposing the light-emitting element 190. The material of the step compensating layer 183 is not particularly limited as long as it has high light transmittance and has step compensating characteristics and insulating characteristics, but examples thereof may include organic materials such as an acrylic resin, an epoxy resin, an imide resin, a cardo-based resin, and an ester resin.

The light-emitting element 190 may be disposed on the step compensating layer 183. The light-emitting element 190 may include an anode 191 (for example, a lower electrode), a cathode 193 (for example, an upper electrode), and a light-emitting layer 195 interposed between the anode 191 and the cathode 193. For example, the light-emitting layer 195 may be an organic light-emitting layer including an organic light-emitting material, and the light-emitting element 190 may be an organic light-emitting element. The light-emitting element 190 may emit only blue light, emit only green light, emit only red light, or emit white light mixed therewith, depending on the material or laminate structure of the light-emitting layer 195.

The anode 191 may be a pixel electrode disposed for each pixel and provided with driving signals independently of each other. The anode 191 may be electrically connected to the drain electrode 139 of the thin film transistor 130 through the contact hole formed in the step compensating layer 183 and the interlayer insulating layer 160. The anode 191 may be a transparent electrode, an opaque electrode, or a laminate structure including both a transparent electrode and an opaque electrode. Examples of the material for forming the transparent electrode may include indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide, and/or indium oxide, and examples of the material for forming the opaque electrode may include lithium (Li), aluminum (Al), magnesium (Mg), silver (Ag), nickel (Ni), and/or chromium (Cr).

The cathode 193 may be a common electrode which is disposed to overlap the anode 191 in the third direction Z and the cathode 193 may be continuously disposed over a plurality of pixels without interruption. For example, the plurality of light-emitting elements 190 disposed in different pixels from each other may share the cathode 193 with each other. Like the anode 191, the cathode 193 may be a transparent electrode, an opaque electrode, or a laminate structure including both a transparent electrode and an opaque electrode.

The light-emitting layer 195 may be interposed between the anode 191 and the cathode 193. Within the light-emitting layer 195, holes and electrons transferred from the anode 191 and the cathode 193, respectively, may recombine to generate light. For example, the holes and electrons are recombined in the light-emitting layer 195 to generate excitons, and the excitons emit light as they relax from the excited state to the ground state. The light-emitting layer 195 may include a material that phosphoresces or fluoresces only blue light, a material that phosphoresces or fluoresces only green light, and/or a material that phosphoresces or fluoresces only red light.

A hole control auxiliary layer such as a hole injection layer, a hole transport layer, or a hole blocking layer; an electron control auxiliary layer such as an electron injection layer, an electron transport layer, or an electron blocking layer; and/or a charge generating auxiliary layer may be further interposed between the light-emitting layer 195 and the anode 191 and/or between the light-emitting layer 195 and the cathode 193, so that the light-emitting efficiency of the light-emitting element 190 can be increased.

In some exemplary embodiments of the present invention, a pixel defining film 185 may be further disposed on the anode 191. The aforementioned light emitting layer 195 and the cathode 193 may be disposed on the pixel defining film 185. In a plan view, the pixel defining film 185 may have an opening partially exposing the anode 191. The pixel defining film 185 may isolate the anode 191 and the cathode 193 from each other, and may partition a plurality of pixels. The pixel defining film 185 may include an organic material such as an acrylic resin, an epoxy resin, an imide resin, and/or an ester resin.

Next, the counter substrate 201 will be described. The counter substrate 201 (for example, a second substrate) may face the light-emitting substrate 101. For example, the counter substrate 201 may be an encapsulating substrate that is disposed over the light-emitting substrate 101 and encapsulates the light-emitting element 190 together with a sealing member 301 to be described later. The counter substrate 201 may include a second base substrate 211, and may further include a touch element layer 231.

The second base substrate 211 is configured to encapsulate the light-emitting element 190 to prevent the light emitting element 190 from being damaged by air, moisture, or the like. The second base substrate 211 may be a transparent plate or a transparent film. For example, the second base substrate 211 may include a glass material, a quartz material, or the like. In some exemplary embodiments of the present invention, the second base substrate 211 and the light-emitting element 190 may be spaced apart from each other, and an inert gas such as nitrogen gas may be disposed therebetween. However, the present invention is not limited thereto, and the space between the second base substrate 211 and the light-emitting element 190 may be filled with a filler or the like.

In an exemplary embodiment of the present invention, in a plan view, the second base substrate 211 may include a main portion 211a having a fourth maximum width W_211a in the first direction X, a first protruding portion 211b protruding from the main portion 211a in the second direction Y, and a second protruding portion 211c protruding from the main portion 211a in the second direction Y and spaced apart from the first protruding portion 211b in the first direction X. The first protruding portion 211b of the second base substrate 211 may have a fifth maximum width W_211b in the first direction X, and the second protruding portion 211c thereof may have a sixth maximum width W_211b in the first direction X. Each of the fifth maximum width W_210b and the sixth maximum width W_211c may be smaller than the fourth maximum width W_211a. For example, the sum of the fifth maximum width W_211b and the sixth maximum width W_211c may be smaller than the fourth maximum width W_211a. The fifth maximum width W_211b and the sixth maximum width W_211c of the second base substrate 211 may be the same as or different from each other. In addition, the second base substrate 211 may have a shape in which the maximum length thereof in the second direction Y is longer than the length thereof in the first direction X, for example, the fourth maximum width W_211a.

The planar area of the second base substrate 211 may be smaller than the planar area of the first base substrate 111.

For example, the main portion 111a of the first base substrate 111 and the main portion 211a of the second base substrate 211 may overlap each other in the third direction Z. Further, the main portion 111a of the first base substrate 111 has substantially the same shape as the main portion 211a of the second base substrate 211, and may have substantially the same area as the main portion 211a of the second base substrate 211. For example, the maximum width W_111a of the main portion 111a of the first base substrate 111 in the first direction X may be substantially the same as the maximum width W_211a of the main portion 211a of the second base substrate 211 in the first direction X, and the length of the main portion 111a of the first base substrate 111 in the second direction Y may be substantially the same as the length of the main portion 211a of the second base substrate 211 in the second direction Y.

The first protruding portion 111b of the first base substrate 111 and the first protruding portion 211b of the second base substrate 211 may overlap the second protruding portion 111c of the first base substrate 111 and the second protruding portion 211c of the second base substrate 211 in the third direction Z, respectively. The first protruding portion 111b of the first base substrate 111 may have a larger planar area than the first protruding portion 211b of the second base substrate 211, and the second protruding portion 111c of the first base substrate 111 may have a larger planar area than the second protruding portion 211c of the second base substrate 211.

In an exemplary embodiment of the present invention, the second maximum width W_111b of the first protruding portion 111b of the first base substrate 111 in the first direction X may be substantially the same as the fifth maximum width W_211b of the first protruding portion 211b of the second base substrate 211 in the first direction X, and the length L_111b of the first protruding portion 111b of the first base substrate 111 in the second direction Y may be greater than the length L_211b of the first protruding portion 211b of the second base substrate 211 in the second direction Y.

Similarly, the third maximum width W_111c of the second protruding portion 111c of the first base substrate 111 in the first direction X may be substantially the same as the sixth maximum width W_211c of the second protruding portion 211c of the second base substrate 211 in the first direction X, and the length L_111c of the second protruding portion 111c of the first base substrate 111 in the second direction Y may be greater than the length L_211c of the second protruding portion 211c of the second base substrate 211 in the second direction Y.

The first protruding portion 111b and the second protruding portion 111c of the first base substrate 111, which are not covered by the first protruding portion 211b and the second protruding portion 211c of the second base substrate 211, may be provided with the light-emitting substrate pad unit 170.

At least a part of the display area DA of the display device 1 may overlap the first protruding portion 211b and second protruding portion 211c of the second base substrate 211. For example, pixels are defined in the first protruding portion 211b and second protruding portion 211c of the second base substrate 211 as well as in the main portion 211a of the second base substrate 211, and the pixels may contribute to image display and color expression. Except for an area where a module member 601, to be described later, is disposed, the display area DA is formed around three sides of the module member 601 (two sides in the first direction X, and 1 side in the second direction Y) thereby minimizing the planar area of the non-display area NA and increasing the planar area of the display area DA.

One side edge (for example, a lower edge in FIG. 5) of the second base substrate 211 in the second direction Y may have an atypical shape such as a bay, a notch, or a trench, in a plan view. For example, one side edge 221 of the second base substrate 211 may be partially indented. For example, one side edge 221 of the second base substrate 211 may include a fourth edge 221b, a fifth edge 221a indented from the fourth edge 221b, and a sixth edge 221c protruding from the fifth edge 221a.

The fourth edge 221b refers to one side edge of the first protruding portion 211b of the second base substrate 211 in the second direction Y, the fifth edge 221a refers to one side edge of the main portion 211a of the second base substrate 211 in the second direction Y, and the sixth edge 221c refers to one side edge of the second protruding portion 211b of the second base substrate 211 in the second direction Y. The first protruding portion 211b, second protrusion portion 211c and fifth edge 221a of the second base substrate 211 may together form a bay.

In an exemplary embodiment of the present invention, the shortest distance D₄ from the fourth edge 221b to the display area DA in the second direction Y may be larger than the shortest distance D₅ from the fifth edge 221a to the display area DA in the second direction Y. Further, the shortest distance from the sixth edge 221c to the display area DA in the second direction Y may be larger than the shortest distance D₅ from the fifth edge 221a to the display area DA in the second direction Y. In some exemplary embodiments of the present invention, the shortest distance D₁ from the first edge 121b to the display area DA may be larger than the shortest distance D₄ from the fourth edge 221b to the display area DA, and the shortest distance D₂ from the second edge 121a to the display area DA may be substantially equal to the shortest distance D₅ from the fifth edge 221a to the display area DA.

As will be described later, the shortest distance D₄ from the fourth edge 221b to the display area DA is larger than the shortest distance D₅ from the fifth edge 221a to the display area DA, thereby sufficiently securing the width of a portion extending in the first direction X (for example, a first linear portion 311 to be described later) of the sealing member 301 disposed on the first protruding portion 211b.

In addition, the first edge 121b of the first base substrate 111 protrudes from the fourth edge 221b of the second base substrate 211 to support the light-emitting substrate pad unit 170, and the second edge 121a of the first base substrate 111 is aligned with the fifth edge 221a of the second base substrate 211, thereby minimizing the area occupied by the light-emitting substrate pad unit 170 and further reducing the area of the non-display area NA.

Hereinafter, a touch element layer 231, including a touch electrode layer 240, touch wirings, 251, and a touch pad unit 271, of the display device 1 according to an exemplary embodiment of the present disclosure will be described in detail with reference to FIGS. 6 to 9.

FIG. 6 is a plan view illustrating a touch element layer 231 of the counter substrate 201 of FIG. 1. FIG. 7 is an enlarged view of the area A in FIG. 6. FIG. 8 is an enlarged view illustrating a first touch electrode 241 and a second touch electrode 242 of FIG. 7. FIG. 9 is a comparative cross-sectional view illustrating a cross-sectional taken along the line IXa-Ixa′ of FIG. 8 and a cross-sectional taken along the line IXb-Ixb′ of FIG. 8.

Referring to FIGS. 6 to 9, a touch element layer 230 including a touch electrode layer 240, touch wirings 251, and a touch pad unit 271 may be disposed on the upper surface of the second base substrate 211.

The touch electrode layer 240 may include a first touch electrode 241 extending in the first direction X and a second touch electrode 242 extending in the second direction Y. The first touch electrode 241 and the second touch electrode 242 may cross each other. A fourth insulating layer 280 may be interposed between the first touch electrode 241 and the second touch electrode 242 to insulate them from each other. The fourth insulating layer 280 may include an inorganic insulating material. Examples of the inorganic insulating material include silicon nitride, silicon oxide, silicon oxynitride, and silicon oxynitride.

The plurality of first touch electrodes 241 may extend in the first direction X, and may be spaced apart from each other in the second direction Y. The first touch electrode 241 may be a transparent electrode. The first touch electrode 241 may include a plurality of first extension portions 241a having a substantially rhombic shape in a plan view and a first connection portion 241b connecting the adjacent first extension portions 241a. The first touch electrode 241 may be a sensing electrode configured to carry a sensing signal.

The plurality of second touch electrodes 242 may extend in the second direction Y, and may be spaced apart from each other in the first direction X. The second touch electrode 242 may be a transparent electrode. The second touch electrode 242 may include a plurality of second extension portions 242a having a substantially rhombic shape in a plan view and a second connection portion 242b connecting the adjacent second extension portions 242a. The second touch electrode 242 may be a driving electrode configured to carry a driving signal.

In an exemplary embodiment of the present invention in which each of the first extension portions 241a and the second extension portion 242a has a rhombic shape, the first extending portion 241a and the second extending portion 242a may be spaced apart from each other in a direction facing each other (for example, a diagonal direction intersecting the first direction X and the second direction Y in the plane). The first connection portion 241b and the second connection portion 242b may intersect each other so as to be insulated from each other. For example, the second connection portion 242b extending in the second direction Y may be disposed on the first connection portion 241b extending in the first direction X, and the fourth insulating layer 280 may be interposed between the first connection portion 241b and the second connection portion 242b.

A mutual capacitance may be formed between the first touch electrode 241 extending in the first direction X and the second touch electrode 242 extending in the second direction Y. When the capacitance between the first touch electrode 241 and the second touch electrode 242 is changed by a user's touch operation, the display device 1 can acquire coordinate information about the user's touch operation based on the changed capacitance. For example, the touch element layer 231 of the counter substrate 201 can acquire the coordinate information about the user's touch operation.

The touch wirings 251 may extend from the non-display area NA, for example, the inner non-display area INA, and may transmit a signal provided from an external driving element to the touch electrode layer 240. For example, the touch wirings 251 may be electrically connected to the touch pad unit 271 to transmit a signal provided from the second flexible circuit film 501 to the touch electrode layer 240. The touch wirings 251 may include a first touch wiring 251a connected with the first touch electrode 241 and a second touch wiring 251b connected with the second touch electrode 242.

The first touch wiring 251a may include first portions 251a1 extending in the first direction X and second portions 251a2 extending in the second direction Y. The second touch wiring 251b may include first portions 251b1 extending in the first direction X and second portions 251b2 extending in the second direction Y. In an exemplary embodiment of the present invention, each of the first touch wiring 251a and the second touch wiring 251b may be located at least partially in the non-display area NA. For example, in a plan view, the first portion 251b1 of the second touch wiring 251b may be located entirely within the sealing member 301.

The touch pad unit 271 (for example, the second pad unit) may be located in the non-display area NA. For example, the touch pad unit 271 may be located at least partially in the outer non-display area ONA. For example, the touch pad unit 271 may at least partially overlap the outer non-display area ONA without being located in the inner non-display area, and may at least partially overlap the sealing area SA. In this case, the touch wirings 251 may at least partially cross the sealing area SA. The planar area occupied by the inner non-display area INA can be minimized by disposing the touch pad unit 271 so as not to be located in the inner non-display area INA.

The touch pad unit 271 may include first pad electrodes 271a connected to the first touch wiring 251a and second pad electrodes 271b connected to the second touch wiring 251b. However, the present invention is not limited thereto, and in an exemplary embodiment of the present invention, the ends of the first touch wiring 251a and the second touch wiring 251b may extend to form the touch pad unit 271 for electrical connection.

The present invention is not limited thereto. For example, when the light-emitting substrate 101 including the light-emitting element 190 and the counter substrate 201 including the touch element layer 231 are respectively manufactured, and then coupled with each other using the sealing member 301, the touch wiring portions 251a1 and 251b1 extending in the first direction X adjacent to the sealing member 301 extending in the first direction X and the touch wiring portions 251a2 and 251b2 extending in the second direction Y adjacent to the sealing member 301 extending in the second direction Y were disposed inward from the sealing member 301, so as to secure the transmittance of a laser traveling from the counter substrate 201 to the sealing member 301 and to cure the sealing member with the laser.

The touch pad unit 271 may be disposed adjacent to one side edge of the second base substrate 211 in the second direction Y. In an exemplary embodiment of the present invention, the touch pad unit 271 including the first pad electrode 271a and the second pad electrode 271b is disposed adjacent to the fourth edge 221b of the second base substrate 211, but might not be disposed adjacent to the fifth edge 221a and the sixth edge 221c. The touch pad unit 271 including the first pad electrode 271a and the second pad electrode 271b is disposed on the first protruding portion 211b of the second base substrate 211, but might not be disposed on the main portion 211a and the second protruding portion 211c, thereby simplifying the connection structure of the second flexible circuit film 501 and minimizing the area of the non-display area NA. In addition, there is an effect of securing a space for disposing a module member 601 to be described later.

Hereinafter, the sealing member 301 of the display device 1 according to exemplary embodiments of the present invention will be described in detail with reference to FIG. 10.

FIG. 10 is a layout view illustrating the light-emitting substrate 101, the counter substrate 201, and the sealing member 301 of FIG. 1.

Referring to FIG. 10, the sealing member 301 may be disposed between the light-emitting substrate 101 and the counter substrate 201 to couple them with each other. For example, the sealing member 301 may be brought into contact with the interlayer insulating layer 160 of the light-emitting substrate 101 and the back surface of the second base substrate 211 of the counter substrate 201. The sealing member 301 may be a cured frit. As used herein, the term “frit” refers to a structure having glass properties formed by melt-curing a powdered glass optionally containing an additive.

In a plan view, the sealing member 301 may form a closed curve and may surround the light-emitting element 190 of the light-emitting substrate 101. For example, the sealing member 301 is configured to seal the light emitting element 190, and thus can prevent the light emitting element 190 from being damaged by air, moisture, or the like. The sealing member 301 may be disposed in the non-display area NA to define the sealing area SA. The planar shape of the sealing member 301 may have a shape substantially corresponding to the planar shape of the first base substrate 111 or the planar shape of the second base substrate 211.

In an exemplary embodiment of the present invention, the sealing member 301 may include a first linear portion 311 extending in the first direction X and a second linear portion 321 extending in the second direction Y.

The first linear portion 311 may have a substantially linear shape. For example, each of the outer edge and the inner edge of the first linear portion 311 of the sealing member 301 may have a substantially linear shape extending in the first direction X. The first linear portion 311 may overlap the first protruding portion 111b of the first base substrate 111 and the first protruding portion 211b of the second base substrate 211. The first linear portion 311 may be a part of the sealing member 301 closest to the first edge 121b of the first base substrate 111 and the fourth edge 221b of the second base substrate 211.

The second linear portion 321 may have a substantially linear shape. For example, each of the outer edge and the inner edge of the second linear portion 321 of the sealing member 301 may have a substantially linear shape extending in the second direction Y. The second linear portion 321 may overlap the main portion 111a of the first base substrate 111 and the main portion 211a of the second base substrate 211. Further, the second linear portion 321 may at least partially overlap the first protruding portion 111b of the first base substrate 111 and the first protruding portion 211b of the second base substrate 211.

The maximum width W₃₁₁ of the first linear portion 311 may be different from the maximum width W₃₂₁ of the second linear portion 321. In an exemplary embodiment of the present invention, the maximum width W₃₁₁ of the first linear portion 311 may be greater than the maximum width W₃₂₁ of the second linear portion 321. For example, the maximum width W₃₁₁ of a portion of the sealing member 301 overlapping the first protruding portion 111b of the first base substrate 111 and the first protruding portion 211b of the second base substrate 211 (for example, the first linear portion 311) may be greater than the maximum width W₃₂₁ of a portion of the sealing member 301 overlapping the main portion 111a of the first base substrate 111 and the main portion 211a of the second base substrate 211 (for example, the second linear portion 321).

The difference between the maximum width W₃₁₁ of the first linear portion 311 and the maximum width W₃₂₁ of the second linear portion 321 may be about 10% or more of the maximum width W₃₂₁ of the second linear portion 321. For example, the maximum width W₃₂₁ of the second linear portion 321 may be within a range of about 400 μm to about 450 μm, and the maximum width W₃₁₁ of the first linear portion 311 may be within a range of about 450 μm to about 550 μm. As used herein, unless otherwise defined, the term “width” refers to a width in a direction perpendicular to an extension direction or a protruding direction. Therefore, width may be thought of here as the line thickness of the first linear portion 311, the second linear portion 321, and the third linear portion 331, as shown in FIG. 10.

The first linear portion 311 may be located adjacent to the light-emitting substrate pad unit 170 and the touch pad unit 271. In a plan view, the first linear portion 311 may be located between the light-emitting substrate pad unit 170 and the touch pad unit 271. The present invention is not limited thereto, but, for example, when the light-emitting substrate pad unit 170 and the first flexible circuit film 401 are connected through a pressing process and/or the touch pad unit 271 and the second flexible circuit film 501 are connected through a pressing process, stress caused by the pressing process may be focused on the first protruding portion 111b of the first base substrate 111, the first protruding portion 211b of the second base substrate 211 and the first linear portion 311 of the sealing member 301. In addition, the light-emitting substrate pad unit 170 is not formed on the main portion 111a of the first base substrate 111, so that the pressure per unit area applied to the first protruding portion 111b of the first base substrate 111 in the pressing process may increase. In the display device 1, according to exemplary embodiments of the present invention, the maximum width W₃₁₁ of the first linear portion 311, which is relatively vulnerable to stress, is sufficiently wide, so that the durability of the display device 1 can be increased. The touch pad unit 271 and the touch wirings 251 of the aforementioned touch element layer 231 may at least partially overlap the first linear portion 311.

In some exemplary embodiments of the present invention, the sealing member 301 may further include a first curved portion 361 extending from the first linear portion 311 and partially curved, and a third linear portion 331 extending from the first curved portion 361 and extending in the first direction X.

In a plan view, the first curved portion 361 may include one or more curved portions. The first curved portion 361 may have a partially curved shape including at least one curved line having a predetermined curvature radius R₆. For example, the first curved portion 361 may be an assembly of curves having different curvature radii.

The first curved portion 361 may include a portion concavely curved toward the display area DA (for example, a portion directly contacting the first linear portion 311) and a portion convexly curved toward the display area DA (for example, a portion directly contacting the third linear portion 331). As used herein, the term “curved portion” includes not only a case where the outer edge and the inner edge of the sealing member are formed entirely within a curved line but also a case where the outer edge and the inner edge of the sealing member has a partially linear section together with a curved section. For example, the present invention is not limited thereto, but there may be a partially straight portion between the concavely curved portion and the convexly curved portion of the first curved portion 361.

The first curved portion 361 may overlap the first protruding portion 111b of the first base substrate 111 and the first protruding portion 211b of the second base substrate 211. Further, the first curved portion 361 may at least partially overlap the main portion 111a of the first base substrate 111 and the main portion 211a of the second base substrate 211.

The third linear portion 331 may have a substantially linear shape. For example, each of the outer edge and the inner edge of the third linear portion 331 of the sealing member 301 may have a substantially linear shape extending in the first direction X. The third linear portion 331 may overlap the main portion 111a of the first base substrate 111 and the main portion 211a of the second base substrate 211. The third linear portion 331 may be a part of the sealing member 301 closest to the second edge 121a of the first base substrate 111 and the fifth edge 221a of the second base substrate 211.

The maximum width W₃₃₁ of the third linear portion 331 may be different from the maximum width W₃₁₁ of the first linear portion 311. In an exemplary embodiment of the present invention, the maximum width W₃₁₁ of the first linear portion 311 may be greater than the maximum width W₃₃₁ of the third linear portion 331. As described above, the maximum width W₃₁₁ of the first linear portion 311, which is relatively vulnerable to stress, is formed to be wider than that of other portions, so that the durability of the display device 1 can be increased, and the shortest distance D₂ from the second edge 121a to the display area DA and the shortest distance D₅ from the fifth edge 221a to the display area DA can be minimized. The maximum width W₃₃₁ of the third linear portion 331 may be the same as or different from the maximum width W₃₂₁ of the second linear portion 321.

In an exemplary embodiment of the present invention in which the maximum width W₃₃₁ of the third linear portion 331 is smaller than the maximum width W₃₁₁ of the first linear portion 311, the width of the first curved portion 361 may decrease from the first linear portion 311 toward the third linear portion 331. For example, the width of the first curved portion 361 may gradually decrease.

In some exemplary embodiments of the present invention, the sealing member 301 may further include a second curved portion 371 extending from the third linear portion 331 and partially curved, and a fourth linear portion 341 extending from the second curved portion 371 and extending in the first direction X.

For example, the second curved portion 371 may include a portion concavely curved toward the display area DA (for example, a portion contacting the fourth linear portion 341) and a portion convexly curved toward the display area DA (for example, a portion contacting the third linear portion 331). The second curved portion 371 may overlap the second protruding portion 111c of the first base substrate 111 and the second protruding portion 211c of the second base substrate 211. Further, the second curved portion 371 may at least partially overlap the main portion 111a of the first base substrate 111 and the main portion 211a of the second base substrate 211.

The fourth linear portion 341 may have a substantially linear shape. For example, each of the outer edge and the inner edge of the fourth linear portion 341 of the sealing member 301 may have a substantially linear shape extending in the first direction X. The fourth linear portion 341 may overlap the second protruding portion 111c of the first base substrate 111 and the second protruding portion 211c of the second base substrate 211.

The maximum width W₃₄₁ of the fourth linear portion 341 may be different from the maximum width W₃₂₁ of the second linear portion 321. In an exemplary embodiment of the present invention, the maximum width W₃₄₁ of the fourth linear portion 341 may be greater than the maximum width W₃₂₁ of the second linear portion 321. For example, the maximum width W₃₂₁ of the second linear portion 321 may be within a range of about 400 μm to about 450 μm, and the maximum width W₃₄₁ of the fourth linear portion 341 may be within a range of about 450 μm to about 550 μm.

In some exemplary embodiments of the present invention, the sealing member 301 may further include a third curved portion 381 disposed between the first linear portion 311 and the second linear portion 321 to connect the first linear portion 311 and the second linear portion 321 and partially curved.

In a plan view, the third curved portion 381 may include one or more curved portions. The third curved portion 381 may have a partially curved shape including at least one curved line having a predetermined curvature radius R₈. For example, the third curved portion 381 may be an assembly of curves having different curvature radii.

The third curved portion 381 may include a portion curved concavely toward the display area DA, but might not include a portion convexly curved toward the display area DA. The third curved portion 381 may overlap the first protruding portion 111b of the first base substrate 111 and the first protruding portion 211b of the second base substrate 211.

In a non-limiting example, the maximum radius curvature R₈ formed by the third curved portion 381 (for example, the curvature radius of a curve having the maximum curvature radius when the third curved portion 381 is an assembly of curves having different curvature radii from each other) may be greater than the maximum radius curvature R₆ formed by the first curved portion 361 (for example, the curvature radius of a curve having the maximum curvature radius when the first curved portion 361 is an assembly of curves having different curvature radii from each other).

As described above, the first curved portion 361 may be located at the bay formed by the edges 121 and 221 of the first base substrate 111 and the second base substrate 211 in the second direction Y, and the third curved portion 381 may be located at the edge of the first base substrate 111 and the second base substrate 211 in the first direction X. The present invention is not limited thereto, but when one side edge 121 of the first base substrate 111 in the second direction Y is partially indented and one side edge 221 of the second base substrate 211 in the second direction Y is partially indented, the external impact applied to the display device 1 may be concentrated/focused in the vicinity of the indented portion. For example, the external impact applied to the display device 1 may be concentrated/focused in the vicinity of the first curved portion 361 as compared with the vicinity of the third curved portion 381. In the display device 1, according to exemplary embodiments of the present invention, the maximum curvature radius R₆ of the first curved portion 361, which is relatively vulnerable to stress, is smaller than the maximum curvature radius R₈ of the third curved portion 381, so that the durability of the display device 1 can be increased.

Meanwhile, the display device 1 may further include a first flexible circuit film 401, a second flexible circuit film 501, and a module member 601.

The light-emitting substrate pad unit 170 of the light-emitting substrate 101 may be connected to the first flexible circuit film 401, and the touch pad unit 271 of the counter substrate 201 may be connected to the second flexible circuit film 501. Although FIG. 2 illustrates that the light-emitting substrate pad unit 170 is connected to the first flexible circuit film 401 through a first anisotropic conductive film 490 and the touch pad unit 271 is connected to the second flexible circuit film 501 through a second anisotropic conductive film 590, the present invention is not limited thereto. Although FIG. 1 shows a state in which the first flexible circuit film 401 and the second flexible circuit film 501 are unfolded without being curved, for convenience of explanation, each of the first flexible circuit film 401 and the second flexible circuit film 501 may be curved toward the back side of the light emitting substrate 101.

The first flexible circuit film 401 may be curved in the second direction Y with flexibility. The first flexible circuit film 401 may include a first base film 411 having insulation properties, conductive patterns disposed on the first base film 411, and a driving IC 431. In an exemplary embodiment of the present invention, the first flexible circuit film 401 may be a flexible printed circuit board (FPCB). However, the present invention is not limited thereto. In an exemplary embodiment of the present invention, the first flexible circuit film 401 includes a chip-on-film package, and the chip-on-film package may be connected to a separate printed circuit board.

The second flexible circuit film 501 may be curved in the second direction Y with flexibility. The second flexible circuit film 501 may include a second base film 511 having insulation properties and conductive patterns disposed on the second base film 511. In some exemplary embodiments of the present invention, the second flexible circuit film 501 further includes a second connector 551, and the second connector 551 of the second flexible circuit film 501 may be connected to the first connector 451 of the first flexible circuit film 401.

The module member 601 may be configured to have an optical sensing function and/or a speaker function.
