     DETAILED DESCRIPTION 
     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&#39;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. 
       FIG. 1  is a perspective view showing a tray for a display apparatus according to one embodiment of the invention.  FIG. 2  is a cross-sectional view showing the tray for the display apparatus of  FIG. 1  taken along a second direction.  FIG. 3  is a cross-sectional view showing the tray for the display apparatus of  FIG. 1  taken along a first direction.

     The first recessed part  132  may be recessed from the plate  130  in a third direction D 3  perpendicular to the first and second directions D 1  and D 2 . 
     The second recessed part  131  may be recessed from the plate  130  in the third direction D 3  and spaced apart from the first recessed part  132  in the second direction D 2 . 
     The first inclined surface  110  may be a surface on which a display panel  10  of the display apparatus is disposed, and may extend from the first recessed part  132  in a direction opposite to the third direction D 3 . The first inclined surface  110  may be inclined at a first angle θ 1  with respect to the plate  130 . The first angle θ 1  may be greater than about 0 degree and less than about 90 degrees. 
     The first inclined surface  110  may include a first protrusion  112  connected to the second inclined surface  120 . The first inclined surface  110  may include a second protrusion  114  adjacent to the first recessed part  132 . The first and second protrusions  112  and  114  may allow a space to form between the display apparatus and the first inclined surface  110 , so that the display apparatus may be effectively prevented from being damaged by undesirable foreign substances between the display apparatus and the first inclined surface  110 . 
     The first inclined surface  110  may further include a third protrusion  116  and a fourth protrusion  118  spaced apart from each other in the first direction D 1 . The third and fourth protrusions  116  and  118  may correspond to both edge display areas of the display apparatus in the first direction D 1  to restrict a fluctuation of the display apparatus in the first direction D 1 . 
     The second inclined surface  120  may be a surface on which a circuit part  20  of the display apparatus is disposed, and may extend from the second recessed part  131  in the direction opposite to the third direction D 3 . The second inclined surface  120  may be inclined at a second angle θ 2  with respect to the plate  130 , and may be connected to the first inclined surface  110 . The second angle θ 2  may be greater than about 0 degree and less than about 90 degrees. 
     In an embodiment, the first inclined surface  110  and the second inclined surface  120  may form a third angle θ 3 . The third angle θ 3  may be greater than or equal to about 90 degrees and less than about 180 degrees. The third angle θ 3  may vary or determined based on an angle between the display panel  10  and the circuit part  20  of the display apparatus. 
     When the display panel  10  and the circuit part  20  of the display apparatus are located on the first inclined surface  110  and the second inclined surface  120 , respectively, an end of the display panel  10  may be located within the first recessed part  132  and spaced apart from a bottom portion of the first recessed part  132  by a predetermined distance, and an end of the circuit part  20  may be located within the second recessed part  131  and spaced apart from a bottom portion of the second recessed part  131  by a predetermined distance. 
     The tray for the display apparatus may be manufactured through injection molding by using a material such as plastic, but the embodiments are not limited thereto. In such an embodiment, the tray for the display apparatus may include at least one selected from various known materials in the art, and may be formed by at least one selected from various known schemes in the art. 
     In an embodiment, as shown in  FIG. 1 , the tray  100  for the display apparatus may have a plurality of reception parts arranged in the first direction D 1  and the second direction D 2 , in which each of the reception parts is formed by the first inclined surface  110  and the second inclined surface  120 , and a plurality of display apparatuses may be simultaneously received in the reception parts. 
     The display apparatus may include a display panel  10  and a circuit part  20 . The circuit part  20  may be connected to the display panel  10  to be inclined at a predetermined angle with respect to the display panel  10 . The display apparatus will be described in greater detail below with reference to  FIGS. 4 and 5 . 
     In an embodiment, various types of display apparatuses including a first substrate, a second substrate, and a light emitting element may be used as the display apparatus. The display apparatus may be a panel of an organic light emitting diode display apparatus, but is not limited thereto. In one alternative embodiment, for example, the display apparatus may be a liquid crystal display apparatus, a plasma display apparatus, a field emission display apparatus, or the like other than the organic light emitting diode display apparatus. 
       FIG. 4  is a perspective view showing an embodiment of a display apparatus transported by the tray for the display apparatus of  FIGS. 1 to 3 .  FIG. 5  is a partial cross-sectional view showing the display apparatus of  FIG. 4 . 
     Referring to  FIG. 4 , an embodiment of a display apparatus may include a display panel  10 , and a circuit part  20  connected to the display panel  10 . 
     The circuit part  20  may include a circuit board part DR and a flexible circuit part DP 2 . 
     The display panel  10  may include a flexible substrate DP 1  on which a pixel structure is disposed, an adhesive layer AD, and a cover window CW. 
     The flexible substrate DP 1  may include or be formed of a transparent or opaque material. In one embodiment, for example, the flexible substrate DP 1  may be a transparent resin substrate having flexibility. In such an embodiment, the transparent resin substrate includes a polyimide substrate, for example. In an alternative embodiment, the flexible substrate DP 1  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 DP 1 . 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 DP 1  and the cover window CW. The adhesive layer AD may attach the flexible substrate DP 1  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 EA 1 , a second edge display area EA 2 , a third edge display area EA 3 , and a fourth edge display area EA 4  that are connected to the main display area MA. 
     The main display area MA may have a rectangular shape extending in a transverse direction A 1  and a longitudinal direction A 2 . 
     The first edge display area EA 1  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 EA 1  may be curved such that an end portion of the first edge display area EA 1  extends in a vertical direction A 3  perpendicular to the main display area MA. 
     The second edge display area EA 2  may be formed at a position opposite to the first edge display area EA 1 , 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 EA 1 . In such an embodiment, the third and fourth edge display areas EA 3  and EA 4  may be curved as described above with respect to the first edge display area EA 1 , 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 EA 1 , EA 2 , EA 3 , and EA 4 . 
     The circuit part  20  may be connected to the end of the first edge display area EA 1 . 
     The circuit board part DR may include wires and a driving circuit for driving the display panel  10 . The circuit board part DR may include a flexible circuit board and the like. 
     The flexible circuit part DP 2  may be disposed between the circuit board part DR and the display panel  10  to electrically connect the circuit board part DR and the display panel  10  to each other. The flexible circuit part DP 2  may include a flexible substrate having flexibility, and may be, for example, integrally formed with the flexible substrate DP 1  as a single unitary unit. 
     The first edge display area EA 1  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 A 3 . 
     In an embodiment, the tray for the display apparatus of  FIGS. 1 to 3  is used, such that the display apparatus is safely received, while a volume of the tray for the display apparatus may be reduced, and handling may be performed more efficiently. 
       FIG. 6  is a cross-sectional view showing a state in which a plurality of trays for a display apparatus are stacked according to an embodiment of the invention. 
     Referring to  FIG. 6 , a first tray  100   a  and a second tray  100   b  may be stacked one on another in a vertical direction, in which a first display apparatus including a first display panel  10   a  and a first circuit part  20   a  may be received on first and second inclined surfaces of the first tray  100   a , and a second display apparatus including a second display panel  10   b  and a second circuit part  20   b  may be received on first and second inclined surfaces of the second tray  100   b . The first and second inclined surfaces of each of the first tray  100   a  and the second tray  100   b  may be inclined at a predetermined angle, so that the first and second display apparatuses may be safely received while being received within a small volume. 
       FIG. 7  is a cross-sectional view showing a tray for a display apparatus according to an alternative embodiment of the invention. 
     Referring to  FIG. 7 , a tray for a display apparatus is substantially the same as the tray for the display apparatus of  FIGS. 1 to 3  except that a seating groove  113  is formed at a portion where the first inclined surface  110  and the second inclined surface  120  meet each other. The same or like elements shown in  FIG. 7  have been labeled with the same reference characters as used above to describe the embodiments of the tray for the display apparatus of  FIGS. 1 to 3 , and any repetitive detailed description thereof will hereinafter be omitted or simplified. 
     In such an embodiment, as shown in  FIG. 7 , a space may be formed between the display apparatus and the tray for the display apparatus by the seating groove  113 , so that the display apparatus may be stably received in the tray for the display apparatus, and simultaneously, a direct impact may be prevented from being applied to a connection portion between the display panel  10  and the circuit part  20  of the display apparatus. Accordingly, the display apparatus is safely received, while the volume of the tray for the display apparatus may be reduced, and the handling may be performed more efficiently.
