The following exemplary embodiments of the present invention are provided to those skilled in the art in order to describe the present invention more completely. Accordingly, shapes and sizes of elements shown in the drawings may be exaggerated for clarity.
Hereinafter, a liquid crystal display panel is used as an example of a display panel. Other display panels may be used. For example, a plasma display panel (PDP), a field emission display (FED) panel, and an organic light emitting diode (OLED) display panel may be used.
A display panel according to an exemplary embodiment of the invention may include a first long side LS1, a second long side LS2 opposite the first long side LS1, a first short side SS1 adjacent to the first long side LS1 and the second long side LS2, and a second short side SS2 opposite the first short side SS1.

In other words, the back cover 120 may be inserted into a first short side SS1, a second short side SS2 opposite the first short side SS1, and a first long side LS1, which is adjacent to the first and second short sides SS1 and SS2 and is positioned between the first short side SS1 and the second short side SS2, of the display module 100M in the sliding manner.
Although not shown, the back cover 120 may include a first protrusion extending toward a second side area opposite a first side area at an end of the first side area, a second protrusion extending toward the first side area at an end of the second side area, and a third protrusion extending toward a fourth side area, which is adjacent to the first side area and the second side area and is opposite to a third side area, at an end of the third side area adjacent to the first side area and the second side area, so as to connect the back cover 120 to the display module 100M in the sliding manner as described above.
The display module 100M may include a first connector corresponding to the first protrusion, a second connector corresponding to the second protrusion, and a third connector corresponding to the third protrusion.
The configuration of the display device is described in detail below.
As shown in
The display module 100M may further include a frame 1000 which is positioned in the rear of the display panel 100 and is connected to the guide panel 200. The frame 1000 may be positioned between the display panel 100 and the back cover 120.
The embodiment of the invention describes that the display module 100M includes the display panel 100, the fixer 300, and the guide panel 200. However, the display module 100M may further include an optical layer, a light source, and/or a top case.
The display panel 100 displaying an image may include a front substrate and a back substrate, which are positioned opposite each other. The fixer 300 may be attached to a non-display area of a back surface of the back substrate of the display panel 100.
The back cover 120 may be connected to the guide panel 200.
Although not shown, the back cover 120 may protect various components positioned between the back cover 120 and the display panel 100.
The fixer 300 may be attached to a back surface of the display panel 100 using an adhesive layer. More specifically, the fixer 300 may be attached to the back surface of the back substrate of the display panel 100 using the adhesive layer.
The plurality of fixers 300 may be attached to the back surface of the display panel 100. For example, at least one fixer 300 may be attached to the back surface of the display panel 100 on a first long side LS1, a first short side SS1, and a second short side SS2 of the display panel 100.
The guide panel 200 may cover the fixer 300 and may be connected to the fixer 300.
The guide panel 200 may be positioned at an edge of the back surface of the display panel 100.
The guide panel 200 may include a first guide panel 210 corresponding to a first side area (i.e., the first short side SS1) of the display panel 100, a second guide panel 220 corresponding to a second side area (i.e., the second short side SS2) of the display panel 100, and a third guide panel 230 corresponding to a third side area (i.e., the first long side LS1) of the display panel 100. It may be preferable, but not required, that the first guide panel 210, the second guide panel 220, and the third guide panel 230 form one body.
The guide panel 200 may include a resin material and a glass fiber material, so as to improve rigidity. This will be described in detail later.
As shown in
More specifically, the groove 350 may be formed at a first surface of the base part 310, and the connector 320 may extend from a second surface opposite the first surface in the vertical direction (i.e., the third direction DR3).
The connector 320 may have an opening 340.
As shown in
As described above, when the fixer 300 is attached to the back surface of the back substrate 102 using the adhesive layer 360, a supporter, such as a pem nut and a boss, and a fastening member, such as a screw, are not used to fasten the fixer 300 to the back substrate 102. Therefore, a fixing process may be simply performed, the manufacturing cost may be reduced, and a thickness of the display device 10 may be reduced.
The display panel 100 may include a front substrate 101 and the back substrate 102, which are positioned opposite each other and are attached to each other to form a uniform cell gap therebetween. A liquid crystal layer (not shown) may be formed between the front substrate 101 and the back substrate 102.
A seal part may be formed between the front substrate 101 and the back substrate 102 to seal the liquid crystal layer.
A color filter may be positioned on the front substrate 101 to implement red, green, and blue colors.
The color filter may include a plurality of pixels each including red, green, and blue subpixels. When light is incident on the color filter, the color filter may generate images corresponding to the red, green, or blue color.
A predetermined transistor, for example, a thin film transistor (TFT) may be formed on the back substrate 102. The transistor may turn on or off liquid crystals in each pixel. In this instance, the front substrate 101 may be referred to as a color filter substrate, and the back substrate 102 may be referred to as a TFT substrate.
The liquid crystal layer may include a plurality of liquid crystal molecules, and the arrangement of the liquid crystal molecules may change by a driving signal supplied by the transistor. Hence, light provided by a backlight unit (not shown) may be incident on the color filter based on changes in the arrangement of the liquid crystal molecules of the liquid crystal layer.
As a result, the color filter may implement red, green, and blue light, and thus a predetermined image may be displayed on the front substrate 101 of the display panel 100.
Since the above-described structure and configuration of the display panel 100 are merely an example, they may be changed, added, or omitted.
As shown in
The back polarizing film 510 may be separated from the fixer 300 by a predetermined distance D1 in the horizontal direction (i.e., the first direction DR1 and/or the second direction DR2).
The front polarizing film 500 may overlap the fixer 300 in the vertical direction (i.e., the third direction DR3).
As shown in
Alternatively, as shown in
Further, although not shown, the base part 310 of the fixer 300 may not have the groove 350. In this instance, the adhesive layer 360 may be formed on the bottom of the base part 310.
As shown in
The resin layer 600 may protect the side of the front substrate 101 and/or the back substrate 102 of the display panel 100 from an impact.
As shown in (A) and (B) of
For example, the guide panel 200 may include a side wall SW extending in the vertical direction (i.e., the third direction DR3), a first extension EXP1 extending from the side wall SW in the horizontal direction (i.e., the first direction DR1 and/or the second direction DR2), a second extension EXP2 extending from the first extension EXP1 in the vertical direction (i.e., the third direction DR3), and a third extension EXP3 extending from the second extension EXP2 in the horizontal direction (i.e., the first direction DR1 and/or the second direction DR2).
The side wall SW, the first extension EXP1, and the second extension EXP2 of the guide panel 200 may form the first groove 710.
A first protuberance 700 extending in the horizontal direction (i.e., the first direction DR1 and/or the second direction DR2) may be formed on an inner surface of the first groove 710 of the guide panel 200. The first protuberance 700 may be used to connect the guide panel 200 to the fixer 300.
As shown in
As described above, when the guide panel 200 includes the first groove 710, the fixer 300 may be connected to the guide panel 200 in the sliding manner.
For example, as shown in
In such a manner, as shown in
As shown in
Further, a pad 800 having elasticity may be disposed between the guide panel 200 and the back surface of the display panel 100. Preferably, the pad 800 may be disposed at a location corresponding to the second groove 720 of the guide panel 200.

As shown in
Further, the guide panel 200 may include the first guide panel 210 corresponding to the first short side SS1 of the display panel 100, the second guide panel 220 corresponding to the second short side SS2 of the display panel 100, and the third guide panel 230 corresponding to the first long side LS1 of the display panel 100. The first, second, and third guide panels 210, 220, and 230 may form one body.
In this instance, it may be preferable, but not required, that the third guide panel 230 has an opening 201, so as to connect the fixer 300 disposed on the first long side LS1 of the display panel 100 to the third guide panel 230.
As shown in (A) of
Next, as shown in (B) of
Afterwards, the opening 201 may be covered using a cover 1100. Namely, the cover 1100 may cover the opening 201.
As shown in
Alternatively, the first protuberance 700 may be inserted into an opening 340 formed in the connector 320 of the fixer 300. For this, a length of the first protuberance 700 of the third guide panel 230 in the horizontal direction (i.e., the first direction DR1 and/or the second direction DR2) may be longer than lengths of the first protuberances 700 of the first and second guide panels 210 and 220 in the horizontal direction (i.e., the first direction DR1 and/or the second direction DR2).
As shown in
In this instance, even if the length of the first protuberance 700 of the third guide panel 230 is relatively short, the first protuberance 700 of the third guide panel 230 may be easily inserted into the opening 340 of the fixer 300.
In this instance, the first protuberance 700 of the third guide panel 230 may protrude from the inner surface of the first groove 710 in the direction far from the center of the display panel 100. For example, the first protuberance 700 of the third guide panel 230 may protrude from the second extension EXP2 of the third guide panel 230 in the direction far from the center of the display panel 100.
As shown in
In this instance, the fixers 300 disposed on the first and second short sides SS1 and SS2 of the display panel 100 may be easily connected to the first and second guide panels 210 and 220 in the sliding manner.
As shown in
It may be preferable, but not required, that the base layer 810 may be formed of a material having elasticity. For example, the base layer 810 may be formed of urethane foam.
The adhesive layer 800 having the above-described configuration may have the elasticity and the flexibility as well as the adhesion. Hence, the adhesive layer 800 may prevent an external force from being applied to the guide panel 200 and thus may prevent the external force from being transferred to the display panel 100.
The adhesive layer 800 having the above-described configuration may be referred to as a foam pad.

The shapes of the first, second, and third connectors 1410, 1420, and 1430 of the frame 1000 may be variously changed. Other shapes of the first, second, and third connectors are described below.
As shown in
In the embodiment of the invention, the first short side SS1 of the frame 1000 may be referred to as a fifth side area, the second short side SS2 of the frame 1000 may be referred to as a sixth side area, the first long side LS1 of the frame 1000 may be referred to as a seventh side area, and the second long side LS2 of the frame 1000 may be referred to as an eighth side area.
As shown in (A) of
The third convex part 1730 may have a groove 1701 which is depressed toward the second long side LS2.
In such a structure, the third protrusion 1230 of the back cover 120 may be inserted into the groove 1701 of the third convex part 1730 in a direction from the first long side LS1 to the second long side LS2.
As shown in (B) of
The first connector 1710 may include a first arm 1712 protruding from the first convex part toward the first long side LS1.
The second connector 1720 may include a second arm 1722 protruding from the second convex part toward the first long side LS1.
Grooves 1711 and 1721, which are depressed toward the second long side LS2, may be respectively formed between the first arm 1712 and the frame 1000 and between the second arm 1722 and the frame 1000.
An example of a method for forming the first, second, and third connectors 1710, 1720, and 1730 is described below.
As shown in
An opening 1051 corresponding to the first, second, and third convex parts is formed in the third horizontal frame part 1050.
Next, as shown in
Hence, at least one of the first and second convex parts may overlap at least one of the second horizontal frame part 1020 and the inclined frame part 1030 of the frame 1000.
Afterwards, as shown in
As shown in
In this instance, the first and second protrusions 1210 and 1220 of the back cover 120 may be easily connected to the first and second connectors 1710 and 1720.
In such a structure, the first protrusion 1210 of the back cover 120 may be inserted into the groove 1711 of the first connector 1710 in the direction from the first long side LS1 to the second long side LS2 in the sliding manner. Further, the second protrusion 1220 of the back cover 120 may be inserted into the groove 1721 of the second connector 1720 in the direction from the first long side LS1 to the second long side LS2 in the sliding manner.
As a result, as shown in
As shown in
As described above, the edge of the front surface and the side of the display panel 100 may be exposed in a state where the back cover 120 is connected to the display module 100M.
The fact that the edge of the front surface of the display panel 100 is exposed may mean that the entire front surface of the display panel 100 is exposed. Hence, the visibility of the display device 10 may be improved.
Further, the fact that the side of the display panel 100 is exposed may mean that a resin layer 600 formed on the side of the front substrate 101 and/or the side of the back substrate 102 of the display panel 100 is exposed.
The guide panel 200 may be covered by the display panel 100. Namely, the guide panel 200 may be positioned in the rear of the display panel 100. In this instance, a visual effect, in which a bezel area of the display device 10 seems to be smaller than its original size, may be obtained.
An external surface EXTS of the guide panel 200 may be exposed. In other words, the external surface EXTS of the side wall SW of the guide panel 200 may be exposed.
In this instance, as shown in
As described above, when the guide panel 200 forms the edge of the display device 10, it may be preferable, but not required, that the guide panel 200 has the sufficiently large rigidity.
The guide panel 200 may include a resin material and a glass fiber material, so as to improve the rigidity of the guide panel 200.
It may be preferable, but not required, that the guide panel 200 further includes a pigment material so as to improve the appearance of the display device 10.
The guide panel 200 may be formed by mixing the resin material, the glass fiber material, and the pigment material, pouring a mixture in a mold, and hardening the mixture. A content of the glass fiber material may be about 20 to 40 part by weight based on total weight of the mixture, so as to sufficiently secure the rigidity of the guide panel 200.
In this instance, even if the side wall of the guide panel 200 is relatively thin, the rigidity of the guide panel 200 may be sufficiently secured.
When the guide panel 200 includes the pigment material, a color of the guide panel 200 may be changed. It may be advantageous in terms of the design of the display device 10.

As shown in
The first part 1800 may include a portion covering the edge of the front surface of the display panel 100.

The fourth part 1830 may extend from a second end E2 opposite the first end E1 of the first part 1800 in the vertical direction (i.e., the third direction DR3) and may be positioned on the front surface of the display panel 100.
The fifth part 1850 may extend from the third part 1820 in the vertical direction (i.e., the third direction DR3).
As shown in
In this instance, the second part 1810 may extend from the first part 1800 in the oblique direction and may include a convexly curved surface.
In the embodiment of the invention, the first part 1800 and the fourth part 1830 of the top case 130 may be commonly referred to as the front part including a portion positioned at the front surface of the display panel 100, and the second, third, and fifth parts 1810, 1820, and 1850 of the top case 130 may be commonly referred to as the side part including a portion positioned at the side of the display panel 100.

The base part 2000 may be attached to the back surface of the display panel 100 using an adhesive layer 2100.
A groove 2002, to which the adhesive layer 2100 is applied, may be formed on a bottom surface (i.e., a first surface S1) of the base part 2000.
Further, a convex part 2001 protruding in the vertical direction (i.e., the third direction DR3) may be formed on an upper surface (i.e., a second surface S2) opposite the bottom surface S1 of the base part 2000.
As shown in
The inner wall 2020 may extend from the upper surface S2 of the base part 2000 in the vertical direction (i.e., the third direction DR3).
The side wall 2010 may include a forward part 2012 extending forward from the base part 2000 in the vertical direction (i.e., the third direction DR3) and a backward part 2011 extending backward from the base part 2000 in the vertical direction (i.e., the third direction DR3).
A length W4 of the backward part 2011 may be longer than a length W5 of the forward part 2012.
Further, the length W4 of the backward part 2011 of the side wall 2010 may be longer than a length of the inner wall 2020 by a predetermined length W3.
The first end E1 of the side wall 2010 is one end of the backward part 2011, and the second end E2 of the side wall 2010 is one end of the forward part 2012. Further, the other end of the backward part 2011 of the side wall 2010 and the other end of the forward part 2012 may be connected to each other.
As shown in
The convex part 2001 may reduce an area of a contact surface between the optical layer 110 and the guide panel 200.
The frame 1000 may be disposed on the inner wall 2020 of the guide panel 200.
Further, the frame 1000 may be connected to the side wall 2010 of the guide panel 200 using a predetermined fastening member S500.
At least one connection hole may be formed in the side of the top case 130 to connect the top case 130 with the back cover 120. For example, as shown in
The first connection hole 1900 may correspond to the first and second protrusions 1210 and 1220 of the back cover 120.
The first and second protrusions 1210 and 1220 may be inserted into the first connection hole 1900.
Alternatively, as shown in
The second connection hole 1910 may correspond to the third protrusion 1230 of the back cover 120.
The third protrusion 1230 may be inserted into the second connection hole 1910.
More specifically, the third protrusion 1230 may be inserted into the second connection hole 1910 in the vertical direction (i.e., the third direction DR3).
As shown in
In this instance, the third protrusion 1230 may sequentially pass through the second connection hole 1910 and the overlap hole 2200.
As shown in
The second protrusion 1220 may include a second main protrusion 1221 extending from an end of the second vertical part 120V2 toward the first vertical part 120V1 and a second auxiliary protrusion 1222 extending from the second main protrusion 1221 in the vertical direction (i.e., the third direction DR3).
Further, the first protrusions 1210 may include a first main protrusion 1211 extending from an end of the first vertical part 120V1 toward the second vertical part 120V2 and a first auxiliary protrusion 1212 extending from the first main protrusion 1211 in the vertical direction (i.e., the third direction DR3).
The second auxiliary protrusion 1222 may further include a portion extending further than the second main protrusion 1221 in a direction from the first long side LS1 to the second long side LS2. Hence, a length X2 of the second auxiliary protrusion 1222 may be longer than a length X1 of the second main protrusion 1221.
Further, the first auxiliary protrusion 1212 may further include a portion extending further than the first main protrusion 1211 in a direction from the first long side LS1 to the second long side LS2. Hence, a length X2 of the first auxiliary protrusion 1212 may be longer than a length X1 of the first main protrusion 1211.
As shown in
Alternatively, the top case 130 may be connected to the frame 1000.
For example, a predetermined fastening member S510 may fasten the fifth part 1850 of the top case 130, the side wall SW of the guide panel 200, and the frame 1000 together.
A method for connecting the first and second protrusions 1210 and 1220 of the back cover 120 to the first connection hole 1900 is described below.
As shown in (A) of
Afterwards, as shown in (B) of
As a result, as shown in (C) of
As described above, the back cover 120 may be connected to the display module 100M in the sliding manner.
As shown in
The display panel 110 may be the component displaying an image in response to a control signal of a controller. The display panel 110 may include a plurality of layers. For example, the display panel 110 may include a front substrate 114 and a back substrate 116.
The front substrate 114 and the back substrate 116 may substantially have the same size. A seal portion for sealing a liquid crystal layer may be positioned between the front substrate 114 and the back substrate 116. A protective plate 112 may be positioned on a front surface of the front substrate 114.
The protective plate 112 may protect the display panel 110 from a damage, a scratch, etc. resulting from an external impact. The protective plate 112 may be substantially transparent. The protective plate 112 may be formed of a material having a strength and/or a hardness greater than the front substrate 114 and/or the back substrate 116. The size of the protective plate 112 may be different from the size of the front substrate 114 and/or the back substrate 116. For example, an area of the protective plate 112 may be greater than an area of the front substrate 114 and/or the back substrate 116.
The guide panel 120 may be positioned on the outer perimeter of the display device 100. For example, the guide panel 120 may be coupled with the side of at least one of the display panel 110, the backlight unit 130, the frame 140, and the back cover 150. The guide panel 120 may be exposed to the outside through a front surface of the display device 100 and/or the side of the display device 100. For example, the guide panel 120 may form a bezel of the display device 100.
The guide panel 120 may be coupled with the display panel 110. Namely, the display panel 110 may be coupled with the display device 100 through the guide panel 120.
The backlight unit 130 may include a plurality of light sources. The backlight unit 130 may be classified into a direct type backlight unit and an edge type backlight unit depending on the disposition of the light sources.
The backlight unit 130 may be coupled with a front surface of the frame 140. For example, the plurality of light sources may be disposed on the front surface of the frame 140. In this instance, the backlight unit may be referred to as the direct type backlight unit.
The backlight unit 130 may include an optical sheet. The optical sheet may diffuse light of the light sources. The optical sheet may include a plurality of layers. For example, the optical sheet may include at least one prism sheet and/or at least one diffusion sheet.
The frame 140 may support the components of the display device 100. For example, the frame 140 may be coupled with the backlight unit 130. The frame 140 may be formed of a metal material, for example, aluminum alloy.
The back cover 150 may be coupled with a back surface of the display device 100. Namely, the back cover 150 may be coupled with the display device 100 so as to shield the frame 140, etc. The back cover 150 may be slidingly coupled with the display device 100. Namely, a predetermined structure may be formed between the display device 100 and the back cover 150 so that the back cover 150 can be easily coupled with the display device 100. The sliding coupling structure of the back cover 150 and the display device 100 will be described in detail later.

As shown in
The resin portion 111 may protect the display panel 110. The resin portion 111 may protect the display panel 110 from an impact applied from the side of the display panel 110.
The resin portion 111 may have characteristic different from the display panel 110. For example, the resin portion 111 may be a material having elasticity. Thus, when an impact is applied to the resin portion 111, the resin portion 111 may be elastically deformed and may absorb the impact.
The resin portion 111 may include a plurality of layers. For example, the resin portion 111 may include a first resin portion 111a directly contacting the side of the substrate 117 and a second resin portion 111b positioned on the outer side of the first resin portion 111a. Namely, the first and second resin portions 111a and 111b may be sequentially stacked in a radial direction of the substrate 117.
The first and second resin portions 111a and 111b may have different characteristics. Namely, it indicates that the first and second resin portions 111a and 111b may be formed of different materials. For example, the first resin portion 111a may be a soft material softer than the second resin portion 111b. In other words, the first resin portion 111a may be a material having a larger deformation degree against an external force than the second resin portion 111b. Thus, when the external force is applied to the side of the substrate 117, the first resin portion 111a of the soft material may firstly absorb the external force, and then the second resin portion 111b of a hard material may absorb the remaining external force.
Each of the first and second resin portions 111a and 111b may have a color. The first and second resin portions 111a and 111b may have different colors. For example, the first resin portion 111a may have a bright color, and the second resin portion 111b may have a dark color. In this instance, because the first resin portion 111a of the bright color is conspicuous, the first resin portion 111a may be the point in terms of the design.
The protective plate 112 may be coupled with one side of the substrate 117. For example, the protective plate 112 may be coupled with a front surface of the substrate 117.
The protective plate 112 may be formed of a material different from the substrate 117. For example, the protective plate 112 may be formed of a material harder than a material of the substrate 117. Thus, the protective plate 112 may protect the substrate 117 from an impact applied from the front.
The protective plate 112 may be larger than the substrate 117. For example, the protective plate 112 may include an extension EA protruding further than the substrate 117 to the outside.
The extension EA of the protective plate 112 may contact the resin portion 111. For example, the first resin portion 111a may contact both the substrate 117 and the extension EA, and the second resin portion 111b may contact both the first resin portion 111a and the extension EA.
The extension EA may protect the substrate 117 from the external impact. The extension EA may be configured so that the resin portion 111 can be stably coupled. Namely, the extension EA may increase an area to which the first and second resin portions 111a and 111b can be attached.

More specifically, a length of the front substrate 114 may be longer than a length of the back substrate 116 by ‘DF’. Alternatively, a length of the back substrate 116 may be longer than a length of the front substrate 114 by a length DF.
When the lengths of the front substrate 114 and the back substrate 116 are different from each other, contact areas between the front and back substrates 114 and 116 and the resin portion 111 may increase. Namely, a contact area and/or a contact length between the front substrate 114 or the back substrate 116 and the resin portion 111 may increase by the length DF of the side of the front substrate 114 or the side of the back substrate 116, compared to when the resin portion 111 contacts the upper sides of the front and back substrates 114 and 116.

The first resin portion 111a may be formed when the protective plate 112 is removed and/or before or after the protective plate 112 is removed. For example, the first resin portion 111a may be formed on the side of the substrate 117 by injecting a liquid or semiliquid resin.

One side of a support clip 145 may be fixed to the frame 140. For example, one end of a first support clip body 145a of the support clip 145 may be coupled with the frame 140. A second support clip body 145b of the support clip 145 may be formed by bending the first support clip body 145a, and a third support clip body 145c of the support clip 145 may be formed by bending the second support clip body 145b.
The second support clip body 145b may contact the guide panel 120. For example, the second support clip body 145b may come in surface contact with the guide panel 120. A deformation of the guide panel 120 may be minimized due to the contact between the second support clip body 145b and the guide panel 120. For example, when the guide panel 120 is deformed by the external force, the second support clip body 145b may support the guide panel 120. Hence, the deformation of the guide panel 120 may be minimized.
The second support clip body 145b may be directly coupled with the guide panel 120. For example, an extension extending from a first guide panel body 120a of the guide panel 120 may be directly coupled with the second support clip body 145b. The support clip 145 may be fixed at an original position due to the coupling between the extension of the first guide panel body 120a and the second support clip body 145b.
The third support clip body 145c may be bent toward the frame 140. An end of the third support clip body 145c may be adjacent to or contact a second frame body 140b of the frame 140. Thus, when the guide panel 120 is deformed by the external force, the end of the third support clip body 145c may contact the second frame body 140b of the frame 140 and may minimize the deformation of the guide panel 120.
A second guide panel body 120b of the guide panel 120 may include a stopper 120c. The stopper 120c may have a shape obtained by protruding inward the second guide panel body 120b. The stopper 120c may be adjacent to or contact the back surface of the frame 140.
The stopper 120c may prevent the deformation of the guide panel 120. Alternatively, the stopper 120c may prevent a predetermined amount of the deformation of the guide panel 120. For example, when the external force is applied downwards to the upper side of the guide panel 120, the deformation of the guide panel 120 may be prevented due to the stopper 120c contacting the guide panel 120.
The second guide panel body 120b of the guide panel 120 may further include a protrusion 120d. The protrusion 120d may have a shape obtained by extending the second guide panel body 120b to the inside. When the upper side of the frame 140 is coupled with the stopper 120c, and the lower side of the frame 140 is coupled with the protrusion 120d, the deformation of the guide panel 120 resulting from the external force may be prevented.
The guide panel 120 may be positioned adjacent to the display panel 110. For example, a front end 120e of the guide panel 120 may be positioned adjacent to the display panel 110 at a separation distance CD therebetween. The separation distance CD between the front end 120e of the guide panel 120 and the display panel 110 may be within several millimeters, so as to improve the design completeness. In this state, when the guide panel 120 is deformed by the external force, the front end 120e of the guide panel 120 may contact the display panel 110. The support clip 145, the stopper 120c, and/or the protrusion 120d of the display device 100 according to the embodiment of the invention may prevent the deformation of the guide panel 120.

The contact portion 120g may contact the second frame body 140b. Thus, even when the external force is applied to the guide panel 120, the contact between the guide panel 120 and the display panel 110 may be prevented by the contact portion 120g.
As shown in (b) of
The guide panel 120 may have a fixed protrusion 120h. The fixed protrusion 120h may contact the support clip 145. The fixed protrusion 120h may support the support clip 145 so that the support clip 145 is fixed at a given position.
As shown in (a) of
A third coupling protrusion 120j may extend from the first coupling protrusion 120h toward the frame 140. The third coupling protrusion 120j may contact the frame 140. The deformation of the guide panel 120 may be prevented by the third coupling protrusion 120j contacting the frame 140.
As shown in (b) of

The guide 142 may be divided into a plurality of areas. For example, the guide 142 may be divided into first to fourth guides 142a to 142d. The first and second guides 142a and 142b may be coupled with first and second short sides of the frame 140, the third guide 142c may be coupled with a first long side of the frame 140, and the fourth guide 142d may be coupled with a second long side of the frame 140.
At least one of the first to fourth guides 142a to 142d may be formed separately from at least one of the remaining guides. For example, the fourth guide 142d may be formed separately from the first to third guides 142a to 142c.

The flange 152 may include a first flange body 153 extending from the back cover 150 and a second flange body 155 which extends from the first flange body 153 by bending inward the first flange body 153. The first flange body 153 may contact the guide 142 coupled with the frame 140. This is described in detail later.
A state where the flange 152 contacts the guide 142 and the back cover 150 is inclined at a predetermined angle may be referred to as a first state. A state where a portion of the flange 152 is detached from the guide 142 and is substantially parallel with the frame 140 may be referred to as a second state. Namely, the back cover 150 may move from the first state to the second state and may be coupled with the frame 140.
As shown in
At least one of the first to fourth guides 145, 146, 147, and 148 may be repeatedly formed along the long side of the frame 140. For example, the second, third, and fourth guides 146, 147, and 148 may be repeatedly formed along the ling side of the frame 140. A set of the guides (for example, 146, 147, and 148) which are repeatedly formed, may correspond to one flange 152 of the back cover 150. Each guide is described in detail below.
As shown in
The fifth guide 149 may include a 5a guide 149a and a 5b guide 149b. The 5a and 5b guides 149a and 149b may be separated from each other at a predetermined distance therebetween.
The back cover 150 may include an extension 152 between slits 154. The slit 154 may include first and second slits 154a and 154b corresponding to the 5a and 5b guides 149a and 149b.
As shown in (a) of

The first guide 145 may include a body portion 145b extending in a z-axis direction and a base portion 145a extending from the body portion 145b. The base portion 145a may be inclined at a predetermined angle. In other words, the base portion 145a may be formed at an oblique angle. Thus, a first flange 152a may be naturally put up on the base portion 145a. Further, the back cover 150 connected to the first flange 152a may be slide on the base portion 145a in an arrow direction D1 shown in
