The above and other features of the invention will become more apparent by describing in further detail embodiments thereof with reference to the accompanying drawings, in which:
The invention now will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. This invention may, however, be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.
It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.
It will be understood that, although the terms “first,” “second,” “third” etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, “a first element,” “component,” “region,” “layer” or “section” discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a”, “an,” “the,” and “at least one” do not denote a limitation of quantity, and are intended to include both the singular and plural, unless the context clearly indicates otherwise. For example, “an element” has the same meaning as “at least one element,” unless the context clearly indicates otherwise. “At least one” is not to be construed as limiting “a” or “an.” “Or” means “and/or.” As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.
Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.
“About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” can mean within one or more standard deviations, or within ±30%, 20%, 10% or 5% of the stated value.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.
Hereinafter, embodiments of the invention will be described in more detail with reference to the accompanying drawings.

In an alternative embodiment, the flexible substrate DP1 may include a quartz substrate, a synthetic quartz substrate, a calcium fluoride substrate, a fluorine-doped quartz substrate (F-doped quartz substrate), a soda lime glass substrate, a non-alkali glass substrate, or the like.
The pixel structure may be disposed or formed on the flexible substrate DP1. In one embodiment, for example, a thin film transistor and a pixel structure electrically connected to the thin film transistor may be included in the display panel 10. The pixel structure may include a first electrode, an organic light emitting layer, and a second electrode. Meanwhile, the pixel structure may have one of various known forms, so the detailed descriptions thereof will be omitted.
The adhesive layer AD may be disposed between the flexible substrate DP1 and the cover window CW. The adhesive layer AD may attach the flexible substrate DP1 to the cover window CW. The adhesive layer AD may include, for example, a pressure-sensitive adhesive layer.
In an electronic device (e.g., a smartphone) including the display apparatus, the cover window CW may constitute a part of an outer surface of the electronic device.
The display panel 10 may include: a main display area MA for displaying an image; and a first edge display area EA1, a second edge display area EA2, a third edge display area EA3, and a fourth edge display area EA4 that are connected to the main display area MA.
The main display area MA may have a rectangular shape extending in a transverse direction A1 and a longitudinal direction A2.
The first edge display area EA1 may be connected to one side of the main display area MA, and may be curved to be inclined at a predetermined angle with respect to the main display area MA. In one embodiment, for example, the first edge display area EA1 may be curved such that an end portion of the first edge display area EA1 extends in a vertical direction A3 perpendicular to the main display area MA.
The second edge display area EA2 may be formed at a position opposite to the first edge display area EA1, and may be curved to be inclined at a predetermined angle with respect to the main display area MA similarly to the first edge display area EA1. In such an embodiment, the third and fourth edge display areas EA3 and EA4 may be curved as described above with respect to the first edge display area EA1, so the detailed descriptions thereof will be omitted.
The display apparatus may further include a non-display area (not shown) surrounding the main display area MA and the first to fourth edge display areas EA1, EA2, EA3, and EA4.

The first edge display area EA1 of the display apparatus may have an inclination close to 90 degrees with respect to the main display area MA. Accordingly, the circuit part 20 may be perpendicular to the display panel 10. Since the circuit part 20 is perpendicular to the display panel 10, the circuit part 20 may be damaged while the display apparatus is transported.
In an embodiment, when a tray for receiving the circuit part 20 is manufactured, a volume of the tray may be increased due to a height of the circuit part 20 in the vertical direction A3.
