[0049] The present invention will now be described more fully below with reference to the accompanying drawings, in which various embodiments are shown. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. More specifically, these embodiments are provided so that the disclosure will be perfect and complete, and these embodiments will fully convey the scope of the present invention to those skilled in the art. The same reference numerals represent the same elements throughout the text.

[0050] It should be understood that when an element is referred to as being related to another element, such as when an element is referred to as being "on" another element, the element may be directly on the other element, or there may be intervening elements between the element and the other element. Conversely, when an element is referred to as being related to another element, such as when an element is referred to as being "directly" "on" another element, there are no intervening elements.

[0051] It should be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, without departing from the teachings herein, the "first element", "first component", "first region", "first layer" or "first part" discussed below may be referred to as a second element, second component, second region, second layer or second part.

[0052] The terms used herein are only used for the purpose of describing specific embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms, including "at least one". "At least one" should not be interpreted as limiting "a" or "an". "Or" means "and / or". As used herein, the wording "and / or" includes any and all combinations of one or more of the relevant listed items. It will be further understood that when used in this specification, the wording "comprise" and / or "comprising" or "include" and / or "including" indicates the presence of stated features, regions, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, regions, wholes, steps, operations, elements, components and / or combinations thereof.

[0053] In addition, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe the relationship of one element to another element as shown in the accompanying drawings. It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation depicted in the accompanying drawings. For example, if the device in one drawing is turned over, the elements described as being on the "lower" side of the other elements will then be oriented on the "upper" side of the other elements. Therefore, the exemplary term "lower" may include both "lower" and "upper" orientations depending on the specific orientation of the drawings. Similarly, if the device in one drawing is turned over, the elements described as being "below" or "below" other elements will then be oriented "above" other elements. Therefore, the exemplary term "below" or "below" may include both upper and lower orientations.

[0054] As used herein, "about" or "approximately" includes the present number and the mean within an acceptable variation range of the particular value as determined by one of ordinary skill in the art taking into account the measurement in question and the errors associated with the 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 present number.

[0055] Unless otherwise defined, all terms (including technical terms and scientific terms) used in this article have the same meaning as those commonly understood by ordinary technicians in the field to which the present disclosure belongs. It should also be understood that terms, such as terms defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant field and the present disclosure, and will not be interpreted in an idealized or overly formalized meaning unless explicitly defined in this article.

[0056] Exemplary embodiments are described herein with reference to cross-sectional views as schematic diagrams of idealized embodiments. As such, deviations from the illustrated shapes due to, for example, manufacturing techniques and / or tolerances are expected. Therefore, the embodiments described herein should not be interpreted as being limited to specific regional shapes as shown herein, but rather include deviations in shape, for example, caused by manufacturing. For example, a region shown or described as flat may typically have rough features and / or nonlinear features. In addition, the sharp angles shown may be rounded. Therefore, the regions shown in the drawings are schematic in nature, and the shapes of these regions are not intended to illustrate the precise shapes of the regions, and are not intended to limit the scope of the current claims.

[0057] In a display device such as a portable terminal, a region having a curvature may display an image, and a non-display region visible to the outside may exist in the region having a curvature. However, since the region having a curvature may be susceptible to external impact, the non-display region existing in the region having a curvature may also be susceptible to external impact.

[0058] Figure 1 is a perspective view showing an embodiment of a display device according to the present invention, and Figure 2 It is shown Figure 1 An exploded perspective view of a display device.

[0059] exist Figure 1 In the present invention, a portable terminal is shown as an application example of a display device according to an embodiment of the present invention. The portable terminal may include a tablet personal computer ("tablet PC"), a smart phone, a personal digital assistant ("PDA"), a portable multimedia player ("PMP"), a game console or a watch-type electronic device. However, the embodiments of the present invention are not limited thereto. The display device according to an embodiment of the present invention may also be applied to relatively large electronic devices (e.g., a television or an external billboard) and relatively small and relatively medium-sized electronic devices (e.g., a personal computer, a notebook computer, a car navigation unit or a camera). However, these are provided only as examples of the present invention, and the display device according to the present invention may also be applied to other electronic display devices without departing from the spirit and scope of the present invention.

[0060] like Figure 1 As shown in , the display device 1000 may include a plurality of regions defined in a display surface DSF. The display surface DSF may include a flat surface FA and a curved surface BA connected to the flat surface FA. The flat surface FA and the curved surface BA may together define the entire display surface DSF.

[0061] The flat surface FA may be defined in its side in top plan view by, for example, Figure 1The curved surface BA may extend from one or more sides of the flat surface FA and may have a curved shape.

[0062] In cross section, the curved surface BA may define a curvature of a curved shape extending from the flat surface FA. The center of curvature of the curved surface BA may be located inside the display device 1000, or outside the display device 1000 (eg, located at Figure 1 1000 below the display device 1000).

[0063] In an embodiment of the present invention, the flat surface FA may have a quadrilateral shape (e.g., a rectangular shape) in a top plan view, and the curved surface BA may be connected to each of the four sides of the flat surface FA having the quadrilateral shape. However, embodiments of the present invention are not limited thereto. In some embodiments, the curved surface BA may be connected to some of the four sides of the flat surface FA having the quadrilateral shape, for example, to at least one side of the flat surface FA.

[0064] The image may be displayed at both the flat surface FA and the curved surface BA, or may be displayed through both the flat surface FA and the curved surface BA. At least a portion of the curved surface BA may display an image that is continuous with the image displayed on the flat surface FA. Another portion of the curved surface BA that is different from the at least a portion may not display an image, or may display an image that is discontinuous with the image displayed on the flat surface FA. However, in an embodiment, the portion of the curved surface BA that does not display an image may be omitted. In an embodiment, a continuous image may be displayed through the flat surface FA together with all portions of the curved surface BA.

[0065] exist Figure 1 , a graphic image of an animal figure is shown as an example of the image IM1 displayed on the flat surface FA, and an icon as a graphic image is shown as an example of the image IM2 displayed on the curved surface BA.

[0066] The flat surface FA may be parallel to a plane defined by the first direction DR1 and the second direction DR2 intersecting each other, and the normal direction of the flat surface FA may be represented by a third direction DR3. This plane direction and the normal direction may also be used as a reference for describing the display device and its components. The third direction DR3 may be a reference direction for distinguishing the front surface and the rear surface of the display device and its components. The third direction DR3 may be a reference direction for distinguishing the thickness of the display device and its components. However, the direction may be a relative concept and may be changed to other directions.

[0067] Reference Figure 1 and Figure 2, the display device 1000 may include a window member 100, a display panel 200, a support member 300, and a rear housing 400. Figure 1 As shown in FIG. 4 , a portion of the rear case 400 may be exposed to the outside of the window member 100 , but is not limited thereto.

[0068] The end portion of each of the window member 100 and the display panel 200 may have a partially curved shape to conform to the Figure 1 The shape of the display surface DSF corresponds to the shape of the display surface DSF. Figure 3 and Figure 4 The shapes of the window member 100 and the display panel 200 are described in detail.

[0069] The window member 100 may be disposed on the display panel 200 in a direction in which an image is displayed (eg, a third direction DR3 ).

[0070] The top surface of the window member 100 may form or define a reference Figure 1 Described display surface DSF.

[0071] In an implementation, for example, the window member 100 may include or be formed of glass, sapphire, or plastic. An image may be transmitted through the window member 100 to be visible from the outside of the display device 1000 .

[0072] The display panel 200 may be coupled to the bottom surface or rear surface of the window member 100, for example, by being adhered to the window member 100. The display panel 200 may generate and display an image. In an embodiment, the display panel 200 may be an organic light emitting display panel that uses light to generate and display an image. The display panel 200 may include four side surfaces, which are formed by respectively forming a plurality of side surfaces of the display panel 200 and a plurality of side surfaces of the display panel 200. Figure 2 The four side surfaces of the display panel 200 may define a curved area of ​​the display panel 200, and the curved area of ​​the display panel 200 may be formed by the four side surfaces of the display panel 200. Figure 2 The portion indicated by the dotted line in may define a flat area of ​​the display panel 200 .

[0073] Although not shown in the drawings, the display device 1000 may further include a flexible printed circuit board and a printed circuit board, which will be described in more detail later.

[0074] Although not shown in the drawings, the display device 1000 may further include a touch sensing unit (not shown). The touch sensing unit may be disposed between the window member 100 and the display panel 200. However, the embodiments of the present invention are not limited thereto. In another embodiment, the touch sensing unit may be disposed within the display panel 200 and form a part of the display panel 200. The touch sensing unit may operate in a resistive method, a capacitive method, or an electromagnetic induction method, and may acquire spatial coordinate information of a point at which a touch event occurs to the touch sensing unit.

[0075] The support member 300 may be located on a bottom surface or a rear surface of the display panel 200 .

[0076] The support member 300 may include a first support member 310, a second support member 320, a third support member 330, and a fourth support member 340. The first to fourth support members 310 to 340 may be disposed to correspond to four side surfaces of the display panel 200, respectively.

[0077] The support member 300 may be disposed to correspond to the curved region of the display panel 200, and thus the support member 300 may support the curved region of the display panel 200 and may improve the mechanical strength of the display device 1000 at the curved region. In addition, since the support member 300 extends along the curved region of the display panel 200, a non-display region of the display panel 200 located at such a curved region may be disposed at a position not overlapping with the window member 100 (or disposed at a position spaced apart from the window member 100), and a display region of the display panel 200 displaying an image may be disposed at a position overlapping with the window member 100. Therefore, the visibility of the curved non-display region of the display panel 200 that does not display an image may be reduced in the display device 1000.

[0078] The rear case 400 may be coupled to the window member 100 to accommodate the display panel 200 and the support member 300 therebetween. The rear case 400 may include a plastic material or a metal material.

[0083] The window flat portion 110 may be disposed in a plane parallel to a plane defined by the first direction DR1 and the second direction DR2, and may have a flat shape. In an embodiment of the present invention, the window flat portion 110 may have an overall chamfered rectangular shape so that the corners of the window flat portion 110 are curved in a top plan view. However, embodiments of the present invention are not limited thereto.

[0084] The window planar portion 110 may define its sides in top plan view, such as by Figure 2The first window curved portion 121, the second window curved portion 123, the third window curved portion 125, and the fourth window curved portion 127 may extend from four sides of the window flat portion 110, respectively. The first window curved portion 121, the second window curved portion 123, the third window curved portion 125, and the fourth window curved portion 127 may have shapes bent or folded from corresponding sides of the window flat portion 110, respectively.

[0151] Refer again Figure 3 , the display device 1000 may further include a flexible printed circuit board FPCB and a printed circuit board PCB.

[0152] The flexible printed circuit board FPCB may electrically connect the display panel 200 to the printed circuit board PCB. The flexible printed circuit board FPCB may be flexible.

[0153] In an embodiment of the present invention, the flexible printed circuit board FPCB may be coupled to the first lower planar portion 251 , such as adhered to the first lower planar portion 251 .

[0154] The printed circuit board PCB may provide a control signal and / or a driving signal to the display panel 200 through the flexible printed circuit board FPCB to display an image, and / or may receive a control signal and / or a driving signal from the display panel 200 through the flexible printed circuit board FPCB. In an embodiment, such signals may be provided to pixels of the display panel 200, but are not limited thereto.

[0155] The printed circuit board PCB may be thicker than the first lower flat portion 251 of the display panel 200 in a direction perpendicular to the first lower flat supporting portion 319, and may be placed in the receiving groove GV provided in the first lower flat supporting portion 319 of the first supporting member 310. The thickness of the printed circuit board PCB may be substantially equal to the sum of the thickness of the first lower flat portion 251 and the depth of the receiving groove GV, which are also obtained in a direction perpendicular to the first lower flat supporting portion 319.

[0156] According to an embodiment of the present invention, the support member 300 may be disposed to correspond to the curved area of ​​the display panel 200, and thus the support member 300 may support the curved area of ​​the display panel 200 and may improve the mechanical strength of the display device 1000. In addition, due to the support member 300 disposed along the curved area of ​​the display device 1000, the non-display area NDA (see Figure 7 as well as Figure 3 and Figure 4 ) may be disposed at a position not overlapping with the window member 100, but the upper curved portions 221, 223, 225, and 227 and the extended flat portions 231, 233, 235, and 237 of the display panel 200 on which an image is displayed may be disposed at a position overlapping with the window member 100. Therefore, considering that the window member 100 allows the lower portion of the display device 1000 to be visible to the outside thereof, a portion of the non-display area NDA of the display device 1000 visible to the outside may be reduced or removed because the window member 100 does not overlap with the portion of the non-display area NDA.

In the display device 1000 according to an embodiment of the present invention, the display panel 200 may have a shape guided by the support member 300. Therefore, the electronic component 600 may be accommodated in the internal space of the support member 300 while reducing the size of the non-display area NDA visible to the outside. Thus, the space utilization of the display device 1000 may be improved or maximized.
