[0059] Figure 1 This is a schematic perspective view of the display device 1 according to an embodiment. Figure 2a and Figure 2b It is shown Figure 1 A perspective view of the display device 1 in a stretched state in a first direction. Figure 2c It is shown Figure 1 A perspective view of the display device 1 in a stretched state in the second direction. Figure 2d It is shown Figure 1 A perspective view of the display device in a stretched state in the first and second directions. Figure 2e It is shown Figure 1 The perspective view of the display device 1 in a state where it is stretched upwards from a third party.

[0060] Reference Figure 1 The display device 1 may include a display area DA and a non-display area NDA. The display area DA may include multiple pixels. The display device 1 can provide a specific image by using light emitted from the multiple pixels. The non-display area NDA may be located outside the display area DA. The non-display area NDA, which does not have any pixels positioned therein, may completely surround the display area DA.

[0061] The display device 1 can be stretched or contracted in various directions. The display device 1 can be stretched in a first direction (e.g., the x-direction and / or the -x-direction) by an external force applied by a user or an external object. In an embodiment, as... Figure 2a and Figure 2bAs shown, the display area DA and / or non-display area NDA of the display device 1 can be stretched in a first direction (e.g., the x-direction and / or the -x-direction). For example, the display area DA and / or non-display area NDA of the display device 1 can be stretched as follows: Figure 2a As shown, it is stretched along the x and -x directions, or it can be as follows: Figure 2b The image shown is stretched along the x-direction while being fixed on one side.

[0062] The display device 1 can be stretched in a second direction (e.g., the y-direction and / or the -y-direction) by an external force applied by a user or an external object. In an embodiment, as... Figure 2c As shown, the display area DA and / or non-display area NDA of the display device 1 can be stretched in the y-direction and the -y-direction. In another embodiment, the display area DA and / or non-display area NDA of the display device 1 can be stretched in the y-direction or the -y-direction while being fixed on one side.

[0063] The display device 1 can be stretched in multiple directions (e.g., in a first direction (e.g., x-direction and / or -x-direction) and a second direction (e.g., y-direction and / or -y-direction)) by an external force applied by a user or an external object. Figure 2d As shown, the display area DA and / or the non-display area NDA of the display device 1 can be stretched in the ±x and ±y directions.

[0064] The display device 1 can be stretched in a third direction (e.g., the z-direction or -z-direction) by an external force applied by a human body part or an external object. In an embodiment, in Figure 2e In one embodiment, a portion of the display device 1 (e.g., a portion of the display area DA) protrudes in the z-direction. In another embodiment, a portion of the display device 1 (e.g., a portion of the display area DA) may protrude along the -z direction (or be recessed along the z-direction).

[0065] Despite Figures 2a to 2e The display device 1 is stretched upward in a first direction, a second direction, and / or a third direction, but the disclosure is not limited thereto. In another embodiment, the display device 1 can be deformed (e.g., bent or twisted) into various irregular shapes along two or more axes.

[0066] Figure 3 This is a schematic plan view of the display device 1 according to an embodiment.

[0067] Multiple pixels can be arranged in the display area DA of the display device 1. Each pixel may include a sub-pixel that emits light of a different color. A light-emitting element corresponding to each sub-pixel may be located in the display area DA. Circuitry for applying electrical signals to the light-emitting element located in the display area DA and to the transistor electrically connected to the light-emitting element may be located in a non-display area NDA surrounding the display area DA. A gate driving circuit GDC may be located in a first non-display area NDA1 and a second non-display area NDA2, located on either side of the display area DA. The gate driving circuit GDC may include a driver for applying electrical signals to the gate electrode of the transistor electrically connected to the light-emitting element. Although in Figure 3 The gate drive circuit GDC is located in each of the first non-display area NDA1 and the second non-display area NDA2, but the disclosure is not limited thereto. In another embodiment, the gate drive circuit GDC may be located in either the first non-display area NDA1 or the second non-display area NDA2.

[0068] The data drive circuit DDC may be located in a third non-display area NDA3 and / or a fourth non-display area NDA4 that connects the first non-display area NDA1 to the second non-display area NDA2. In an embodiment, in Figure 3 In one embodiment, the data driving circuit DDC is located in the fourth non-display area NDA4. In another embodiment, the data driving circuit DDC may be located in each of the third non-display area NDA3 and the fourth non-display area NDA4.

[0069] Despite Figure 3 The data driving circuit DDC is located in the fourth non-display area NDA4 of the display device 1, but the disclosure is not limited thereto. In another embodiment, the display device 1 may further include a flexible circuit board (not shown) electrically connected via terminal units (not shown) located in the fourth non-display area NDA4, and the data driving circuit DDC may be located on the flexible circuit board.

[0070] In some embodiments, the elongation rate of the non-display area NDA may be equal to or less than the elongation rate of the display area DA. In embodiments, the elongation rate of the non-display area NDA may be different for each area. For example, the first non-display area NDA1, the second non-display area NDA2, and the third non-display area NDA3 may have substantially the same elongation rate, but the elongation rate of the fourth non-display area NDA4 may be less than the elongation rate of each of the first non-display area NDA1, the second non-display area NDA2, and the third non-display area NDA3.

[0071] Figure 4a This illustrates an embodiment. Figure 3An enlarged plan view of part IV of the display device 1.

[0072] Reference Figure 4a The display device 1 may include first island portions 11 spaced apart from each other in a first direction (e.g., x direction or -x direction) and a second direction (e.g., y direction or -y direction) and a first bridging portion 12 connecting adjacent first island portions 11.

[0073] Each first island 11 may be connected to a plurality of first bridging portions 12. For example, each first island 11 may be connected to four first bridging portions 12. Two first bridging portions 12 may be located on either side of the first island 11 along a first direction (e.g., the x-direction or the -x-direction), and the remaining two first bridging portions 12 may be located on either side of the first island 11 along a second direction (e.g., the y-direction or the -y-direction). In an embodiment, the four first bridging portions 12 may be connected to the four sides of the first island 11 respectively. Each of the four first bridging portions 12 may be adjacent to each of the corners of the first island 11.

[0074] The first bridging portions 12 may be spaced apart from each other by first openings CS1 located between the first bridging portions 12. In an embodiment, first openings CS1 having a substantially H-shape and first openings CS1 having a substantially I-shape obtained by rotating the H-shape by 90 degrees may be arranged alternately and repeatedly along a first direction (e.g., the x-direction or the -x-direction) and a second direction (e.g., the y-direction or the -y-direction). The two ends of each first bridging portion 12 may be connected to adjacent first island portions 11 respectively, and one side of each first bridging portion 12 may be spaced apart from one side of an adjacent first island portion 11 and / or one side of another first bridging portion 12 by the first openings CS1.

[0075] The display device 1 can be used in a non-display area (e.g., Figure 4a The first non-display area (NDA1) includes second island portions 21 spaced apart from each other and second bridging portions 22 connecting adjacent second island portions 21.

[0076] Each second island 21 may extend along a first direction (e.g., the x-direction or the -x-direction). The second islands 21 may be spaced apart from each other along a second direction (e.g., the y-direction or the -y-direction) intersecting the first direction (e.g., the x-direction or the -x-direction). Each second island 21 may include a reference... Figure 3 The driver of the gate drive circuit GDC (see Figure 2) is described.

[0077] The second bridging portion 22 may have a serpentine shape. The length of the second bridging portion 22 may be greater than the shortest distance between adjacent second island portions 21 along a second direction (e.g., the y-direction or the -y-direction). In an embodiment, the second bridging portion 22 may have a substantially omega (Ω) shape that protrudes toward a first direction (e.g., the x-direction or the -x-direction). The second bridging portion 22 may be located between adjacent second island portions 21 and may be spaced apart from each other.

[0078] The second bridging portions 22 between adjacent second island portions 21 can be spaced apart from each other by a second opening CS2. Between adjacent second island portions 21, the second opening CS2 and the second bridging portions 22 can be arranged alternately along a first direction (e.g., the x-direction or the -x-direction). The second opening CS2 can have the same shape. Both ends of each second bridging portion 22 can be connected to adjacent second island portions 21 respectively, and one side of each second bridging portion 22 can be spaced apart from one side of an adjacent second island portion 21 and / or one side of another second bridging portion 22 by the second opening CS2.

[0079] Any second island 21 located in the first non-display area NDA1 can correspond to a first island 11 arranged in multiple rows in the display area DA. For example, any second island 21 located in the first non-display area NDA1 can correspond to a first island 11 arranged in the i-th row and a first island 11 arranged in the (i+1)-th row in the display area DA (where i is a positive number greater than 0). Although in Figure 4a In this embodiment, one second island 21 corresponds to two rows of first islands 11, but the disclosure is not limited thereto. In another embodiment, any second island 21 located in the first non-display area NDA1 may correspond to n rows of first islands 11 located in the display area DA (where n is a positive number of 3 or greater).

[0080] The non-display area (e.g., the first non-display area NDA1) may include a first sub-non-display area SNDA1 in which a second island portion 21 and a second bridging portion 22 are positioned, and a second sub-non-display area SNDA2 between the first sub-non-display area SNDA1 and the display area DA. A third bridging portion 23 for connecting the display area DA to the first sub-non-display area SNDA1 may be located in the second sub-non-display area SNDA2. One end of the third bridging portion 23 may be connected to the second island portion 21 and / or the second bridging portion 22, and the other end of the third bridging portion 23 may be connected to the first island portion 11 and / or the first bridging portion 12.

[0081] The third bridging portion 23 may have a serpentine shape. In an embodiment, the shape of the third bridging portion 23 may differ from the shape of each of the first bridging portion 12 and the second bridging portion 22. In an embodiment, such as Figure 4aAs shown, the third bridging portion 23 may have a substantially omega (Ω) shape protruding toward a second direction (e.g., the y-direction or the -y-direction). Adjacent third bridging portions 23 arranged along the second direction (e.g., the y-direction or the -y-direction) may have a symmetrical structure, in which one of the adjacent third bridging portions 23 protrudes in the y-direction and the other of the adjacent third bridging portions 23 protrudes in the -y-direction. Third openings CS3 and fourth openings CS4 with different shapes may be repeatedly arranged between the third bridging portions 23. The width of the third bridging portion 23 may be different from the width of the first bridging portion 12 and the width of the second bridging portion 22. In an embodiment, the width of the third bridging portion 23 may be greater than the width of the first bridging portion 12 and may be less than the width of the second bridging portion 22.

[0082] exist Figure 4a In this embodiment, the second island portion 21 and the second bridging portion 22 of the non-display area (e.g., the first non-display area NDA1) have different shapes from the first island portion 11 and the first bridging portion 12 of the display area DA. In another embodiment, the second island portion 21 and the second bridging portion 22 of the non-display area may have the same shapes as the first island portion 11 and the first bridging portion 12 of the display area DA, respectively.

[0083] Figure 4b This illustrates an embodiment. Figure 3 An enlarged plan view of part IV of the display device 1.

[0084] Reference Figure 4b The display device 1 includes first island portions 11 spaced apart from each other in the display area DA, and first bridging portions 12 spaced apart from each other and connected to adjacent first island portions 11 through first openings CS1. Figure 4b The structure of the display area DA can be compared with the reference. Figure 4a The structures of the described display area DA are the same.

[0085] The display device 1 may include a second island portion 21 and a second bridging portion 22. In an embodiment, the second island portion 21 and the second bridging portion 22 may each have substantially the same shape as the first island portion 11 and the first bridging portion 12.

[0086] The second island portions 21 may be spaced apart from each other in a first direction (e.g., x-direction or -x-direction) and a second direction (e.g., y-direction or -y-direction) within a non-display area (e.g., the first non-display area NDA1). Each of the second bridging portions 22 may connect adjacent second island portions 21. The second bridging portions 22 may be spaced apart from each other through a second opening CS2 located between the second bridging portions 22.

[0087] The second opening CS2 may have a substantially the same shape as the first opening CS1. For example, a second opening CS2 having a substantially H shape and a second opening CS2 having a substantially I shape may be arranged alternately and repeatedly in a non-display area (e.g., a first non-display area NDA1). Both ends of each second bridging portion 22 may be connected to an adjacent second island portion 21, and one side of each second bridging portion 22 may be spaced apart from one side of an adjacent second island portion 21 and / or one side of another second bridging portion 22 by means of the second opening CS2.

[0088] Each second island 21 can be connected to four second bridge sections 22. Each second island 21 may include references. Figure 3 The driver of the gate drive circuit GDC (see Figure 2) is described.

[0089] The second island 21 located in any row of the first non-display area NDA1 can correspond to the first island 11 arranged in any row of the display area DA. For example, the second island 21 arranged in the i-th row along a first direction (e.g., the x-direction or the -x-direction) in the first non-display area NDA1 can correspond to the first island 11 arranged in the same row (e.g., the i-th row) in the display area DA (where i is a positive number greater than 0).

[0090] Display device 1 may include a third bridging portion 23 located in a second sub-non-display area SNDA2 for connecting display area DA to a first sub-non-display area SNDA1. The non-display area (e.g., the first non-display area NDA1) may include a first sub-non-display area SNDA1 and a second sub-non-display area SNDA2. A second island portion 21 and a second bridging portion 22 are positioned in the first sub-non-display area SNDA1. The second sub-non-display area SNDA2 includes the third bridging portion 23 and is located between the first sub-non-display area SNDA1 and the display area DA. The third bridging portion 23 may be substantially the same as the first bridging portion 12 and the second bridging portion 22. For example, the width of the third bridging portion 23 may be the same as the width of the first bridging portion 12 and the width of the second bridging portion 22.

[0091] Figure 4c This illustrates an embodiment. Figure 3 An enlarged plan view of part IV of the display device.

[0092] Reference Figure 4c The display device 1 may include first island portions 11 spaced apart from each other in a first direction (e.g., x direction or -x direction) and a second direction (e.g., y direction or -y direction) in the display area DA, and first bridging portions 12 connecting adjacent first island portions 11.

[0093] The first bridging portions 12 can be spaced apart from each other by first openings CS1 located between the first bridging portions 12. The first bridging portions 12 can have a serpentine shape. For example, as Figure 4c As shown, the first bridging portion 12 may have a generally “letter S” shape.

[0094] Each first island 11 may be connected to a plurality of first bridging portions 12. For example, each first island 11 may be connected to four first bridging portions 12. Two first bridging portions 12 may be located on either side of the first island 11 along a first direction (e.g., the x-direction or the -x-direction), and the remaining two first bridging portions 12 may be located on either side of the first island 11 along a second direction (e.g., the y-direction or the -y-direction). The four first bridging portions 12 may be connected to the four sides of the first island 11 respectively. Each of the four first bridging portions 12 may be adjacent to each of the corners of the first island 11.

[0095] The display device 1 may be included in a non-display area (e.g., Figure 4c The first non-display area NDA1) includes second island portions 21 spaced apart from each other in a first direction (e.g., x direction or -x direction) and a second bridging portion 22 connecting adjacent second island portions 21.

[0096] The second bridging portions 22 can be spaced apart from each other by a second opening CS2 located between the second bridging portions 22.

[0154] Figure 8 This is a schematic plan view showing the shape of a substrate applicable to a display device according to an embodiment. Figure 9 This is an enlarged plan view showing the shape of the bridging portion and sub-island of a substrate applicable to a display device according to an embodiment.

[0156] The base portion 101 can be arranged at specific intervals in a first direction (x-direction) and a second direction (y-direction), and can include a flat top surface. For example... Figure 8 As shown, the base portion 101 may have a cross shape with its corners recessed from an imaginary square. However, the disclosure is not limited to this. The base portion 101 may have any of a variety of shapes, such as a polygonal shape, a polygonal shape with rounded (rounded) corners, a circular shape, an elliptical shape, or an irregular shape.

The opening CS can be located between the base portions 101 and between the bridging portions 103. The opening CS can provide separation areas between the multiple base portions 101, reducing the weight of the substrate 100 and improving its flexibility. Furthermore, because the shape of the opening CS changes when the substrate 100 is bent, folded, or rolled, stress generation during deformation of the substrate 100 can be easily reduced, thereby preventing abnormal deformation of the substrate 100 and improving durability. Therefore, when using the display device 10, user convenience can be improved; specifically, the display device 10 can be easily applied to wearable devices.

[0163] In some embodiments, sub-island 105 may include a first sub-island 105a, a second sub-island 105b, a third sub-island 105c, and a fourth sub-island 105d.

[0164] The first sub-island 105a can be connected to the right side of the base portion 101. The first sub-island 105a can be a region protruding from the base portion 101 in a first direction (x direction). The second sub-island 105b can be connected to the upper side of the base portion 101. The second sub-island 105b can be a region protruding from the base portion 101 in a second direction (y direction).

[0165] The third sub-island 105c can be connected to the left side of the base portion 101. The third sub-island 105c can be a region protruding from the base portion 101 in a direction opposite to the first direction (-x direction). The fourth sub-island 105d can be connected to the lower side of the base portion 101. The fourth sub-island 105d can be a region protruding from the base portion 101 in a direction opposite to the second direction (-y direction).

[0166] In some embodiments, the area of ​​each of the first sub-island 105a, the second sub-island 105b, the third sub-island 105c, and the fourth sub-island 105d may be smaller than the area of ​​the connected base portion 101. However, the disclosure is not limited thereto. Various modifications can be made. For example, the area of ​​each of the first sub-island 105a, the second sub-island 105b, the third sub-island 105c, and the fourth sub-island 105d may be equal to or greater than the area of ​​the connected base portion 101.

[0167] Reference Figure 9The bridging portion 103 may include a first portion SS1 that bends protruding in a third direction in the xy-plane and a second portion SS2 connected to the first portion SS1 and bending protruding in a fourth direction opposite to the third direction in the same plane. The first portion SS1 and the second portion SS2 may be curved portions in the plan view. The third and fourth directions may be directions intersecting the x-direction or the y-direction. However, the disclosure is not limited thereto. The third and fourth directions may be directions parallel to the x-direction or the y-direction.

[0168] The third portion SS3 of the bridging portion 103, which connects the first portion SS1 to the second portion SS2, can be located between the first portion SS1 and the second portion SS2 of the bridging portion 103, and the third portion SS3 can correspond to the inflection point of the bridging portion 103. The third portion SS3 can be a straight line portion that is not curved in a plan view. The third portion SS3 can be a region with a smaller strain than the first portion SS1 and the second portion SS2. The first portion SS1, the second portion SS2, and the third portion SS3 can be arranged continuously. The bridging portion 103 can have an S-shape when viewed as a whole.

[0169] The first part SS1 and the second part SS2 are regions subjected to strain, and the radius of curvature of each of the first part SS1 and the second part SS2 can be designed to be large in order to minimize strain. Therefore, the space occupied by the bridging part 103 can be increased, and the space occupied by the base part 101 can be relatively reduced.

[0170] In this embodiment, by introducing a sub-island 105 connected to the base portion 101, it can be ensured that space can be positioned for light-emitting elements and / or pixel driving circuit units.

[0171] The sub-island 105 may be located between the base portion 101 and the bridging portion 103, and at least a portion of the sub-island 105 may correspond to the shape of the bridging portion 103. That is, at least a portion of the outer side of the sub-island 105 may have a radius of curvature corresponding to the first portion SS1 of the bridging portion 103. An opening CS may be provided between the sub-island 105 and the bridging portion 103, and at least a portion of the opening CS may be provided at specific intervals.

[0172] Due to external forces, the shapes of the multiple bridging portions 103 can change, and the lengths of the multiple bridging portions 103 can increase or decrease. When the external forces are removed, the multiple bridging portions 103 can return to their original shapes. Specifically, when the first part SS1 and the second part SS2 unfold, the length of the bridging portion 103 can increase, or when the first part SS1 and the second part SS2 contract, the length of the bridging portion 103 can decrease. Therefore, the spacing between the multiple base portions 101 can be changed by the multiple bridging portions 103, and thus, the shape of the base 100 can be changed in two dimensions or three dimensions.

[0173] Furthermore, since the openings CS, which are empty spaces, are formed between the multiple bridging portions 103, the substrate 100 can have a grid pattern, and therefore, the substrate 100 can be highly flexible.

[0174] The multiple sub-islands 105 can be regions that are not directly connected to the bridging portion 103 and therefore hardly deform under external forces. In addition, the multiple sub-islands 105 can be regions with minimal strain.

[0175] Figure 10a and Figure 10b This is a schematic plan view showing the shape of a substrate applicable to a display device according to an embodiment.

[0176] Reference Figure 10a and Figure 10b According to this embodiment, the substrate 100 may include a base portion 101, a bridging portion 103, a sub-island 105, and an opening CS. The base portion 101, the bridging portion 103, and the sub-island 105 may be integrally formed with each other. The opening CS may be located between the base portions 101 and between the bridging portions 103.

[0177] The base 101 and the sub-island 105 can have various shapes. Figure 10a and Figure 10b A modified embodiment of the shape of the base portion 101 and the sub-island 105 is shown.

[0178] like Figure 10a As shown, each of the base portion 101 and the sub-island 105 can have a quadrilateral shape. Figure 10b As shown, the base portion 101 may have a circular shape, and at least a portion of each of the sub-islands 105 may have a circular shape.

[0179] The sub-island 105 may include a first sub-island 105a, a second sub-island 105b, a third sub-island 105c, and a fourth sub-island 105d projecting outward from the outer side of the base portion 101. The ends of the sub-islands 105 may contact the opening CS, and at least a portion of each of the sub-islands 105 may be surrounded by the opening CS.

[0180] Sub-island 105 and bridging portion 103 can alternately surround base portion 101. That is, from the outside of base portion 101 in a counterclockwise direction, a first sub-island 105a, a first bridging portion 103a extending in the +x direction, a second sub-island 105b, a second bridging portion 103b extending in the +y direction, a third sub-island 105c, a first bridging portion 103a extending in the -x direction, a fourth sub-island 105d, and a second bridging portion 103b extending in the -y direction can be arranged.

[0181] Figure 11 This is a schematic plan view illustrating the pixel arrangement or light-emitting element arrangement structure of a display device according to an embodiment.

[0182] Reference Figure 11 In a display device, multiple unit pixels UP can be arranged repeatedly in the x and y directions. A unit pixel UP may include a first sub-pixel PX1, a second sub-pixel PX2, and a third sub-pixel PX3 that emit different colors of light. The first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 can be a red pixel, a green pixel, and a blue pixel, respectively.

[0183] The first sub-pixel PX1 can be located on the first sub-island 105a. The first sub-pixel PX1 can be implemented by a first light-emitting element. The first light-emitting element can be located on the first sub-island 105a.

[0184] The second sub-pixel PX2 can be located on the second sub-island 105b. The second sub-pixel PX2 can be implemented by a second light-emitting element. The second light-emitting element can be located on the second sub-island 105b.

[0185] The third sub-pixel PX3 can be located on the third sub-island 105c. The third sub-pixel PX3 can be implemented by a third light-emitting element. The third light-emitting element can be located on the third sub-island 105c.

[0186] The first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 can be located at the vertices of a virtual triangle. The virtual triangle can be an isosceles triangle. The distance between the center of the first sub-pixel PX1 and the center of the second sub-pixel PX2 can be the same as the distance between the center of the second sub-pixel PX2 and the center of the third sub-pixel PX3. The distance between the center of the first sub-pixel PX1 and the center of the third sub-pixel PX3 can be greater than the distance between the center of the first sub-pixel PX1 and the center of the second sub-pixel PX2. The first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 can form a group to achieve a single pixel UP.

[0187] In some embodiments, the light-emitting element may not be located on the fourth sub-island 105d.

[0188] In this embodiment, since the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 are not located on the base portion 101, but on the first sub-island 105a, the second sub-island 105b, and the third sub-island 105c, the display device receives minimal strain when stretched or contracted, thereby ensuring reliability.

[0189] Furthermore, according to the embodiment, since the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 are distributed, the aperture ratio visibility of the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 can be improved.

[0190] Figure 12a and Figure 12b This is a plan view illustrating the arrangement of the pixel driving circuit units and the wiring of the display device according to an embodiment. Figure 12a and Figure 12b For ease of explanation, only some components are shown in the diagram.

[0191] Reference Figure 12a The first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3 can be located on the base part 101.

[0192] The first wiring WL1 may be located on the first bridging portion 103a and may be electrically connected to the first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3. As a signal line such as a scan line or a transmit control line, the first wiring WL1 may provide scan signals or transmit control signals to the first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3.

[0193] The first wiring WL1 may extend in a first direction and may be bent along the shape of the first bridging portion 103a. The first wiring WL1 may include at least two bent portions on the first bridging portion 103a. The first wiring WL1 may be continuously located in the first bridging portion 103a and the base portion 101.

[0194] The second wiring WL2 can be located on the second bridging part 103b and can be electrically connected to the first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3. As a data line, the second wiring WL2 can provide data signals to the first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3.

[0195] The second wiring WL2 may extend in a second direction and may be bent along the shape of the second bridging portion 103b. The second wiring WL2 may include at least two bent portions on the second bridging portion 103b. The second wiring WL2 may be continuously located in the second bridging portion 103b and the base portion 101.

[0196] The first wiring WL1 and the second wiring WL2 can be located on the same layer in the first bridging portion 103a and the second bridging portion 103b, or they can be located on different layers in the base portion 101. The first wiring WL1 and the second wiring WL2 can be configured as a combination of wirings located on different layers. The first wiring WL1 and the second wiring WL2 can cross each other in the base portion 101.

[0197] The first pixel driving circuit unit PC1 can be used to drive the first sub-pixel PX1 (see...). Figure 11 The first pixel driving circuit unit PC1 is a pixel driving circuit unit for the first light-emitting element. Because the first light-emitting element is located on the first sub-island 105a, the first pixel driving circuit unit PC1 can be connected to the first light-emitting element through the first connection wiring (not shown).

[0198] The second pixel driving circuit unit PC2 can be used to drive the second sub-pixel PX2 (see...). Figure 11 The second pixel driving circuit unit PC2 is a pixel driving circuit unit for the second light-emitting element. Because the second light-emitting element is located on the second sub-island 105b, the second pixel driving circuit unit PC2 can be connected to the second light-emitting element through the second connection wiring (not shown).

[0199] The third pixel driving circuit unit PC3 can be used to drive the implementation of the third sub-pixel PX3 (see...). Figure 11 The pixel driving circuit unit of the third light-emitting element is located on the third sub-island 105c. Since the third light-emitting element is located on the third sub-island 105c, the third pixel driving circuit unit PC3 can be connected to the third light-emitting element through the third connection wiring (not shown).

[0200] Despite Figure 12a The first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3 are located on the substrate 101, but the disclosure is not limited thereto. Figure 12b As shown, the first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3 can be located on the sub-island 105, respectively.

[0201] For example, the first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3 can be located on the first sub-island 105a, the second sub-island 105b, and the third sub-island 105c, respectively. The first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3 can be electrically connected to the first wiring WL1 and the second wiring WL2. Therefore, the first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3 can be connected to the first wiring WL1 and the second wiring WL2 via connecting wiring (not shown).

[0202] First sub-pixel PX1 (see Figure 11 The second sub-pixel PX2 (see...) can be stacked with the first pixel driving circuit unit PC1. Figure 11 It can be stacked with the second pixel driving circuit unit PC2. The third sub-pixel PX3 (see...) Figure 11 It can be stacked with the third pixel driving circuit unit PC3.

[0203] However, disclosure is not limited to this. Various modifications can be made. For example, with Figure 12a and Figure 12b Unlike other methods, at least one of the first pixel driving circuit unit PC1, the second pixel driving circuit unit PC2, and the third pixel driving circuit unit PC3 can be located on the base portion 101, while the others can be located on the sub-island 105.

[0204] Figure 13a and Figure 13b This is a schematic plan view illustrating the pixel arrangement or light-emitting element arrangement structure of a display device according to an embodiment. Figure 13a and Figure 13b In, with Figure 11 The same components are represented by the same reference numerals.

[0205] Reference Figure 13a and Figure 13b In a display device, multiple unit pixels UP can be arranged repeatedly in the x and y directions. A unit pixel UP may include a first sub-pixel PX1, a second sub-pixel PX2, and a third sub-pixel PX3 that emit different colors of light. The first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 can be a red pixel, a green pixel, and a blue pixel, respectively.

[0206] Reference Figure 13aThe unit pixel UP may further include a fourth sub-pixel PX4. In some embodiments, the fourth sub-pixel PX4 may be a red pixel, a green pixel, a blue pixel, or a white pixel. Various modifications are possible. For example, the color of the fourth sub-pixel PX4 may be the same or different for each unit pixel UP. The fourth sub-pixel PX4 may be located on the fourth sub-island 105d. Because the fourth sub-pixel PX4 is positioned, the visibility of the display device can be improved.

[0207] In some embodiments, when the light-emitting element is an organic light-emitting diode, the fourth sub-pixel PX4 can be a green pixel. In this case, the unit pixel UP can include two green pixels, one red pixel, and one blue pixel.

[0208] In an embodiment, when the light-emitting element is an inorganic light-emitting diode, the fourth sub-pixel PX4 can be a red pixel. In this case, the unit pixel UP can include two red pixels, one green pixel, and one blue pixel.

[0209] Reference Figure 13b The unit pixel UP may also include a sensor PD. In some embodiments, the sensor PD may be a light sensor. For example, the sensor PD may be a visible light (VIS) sensor or an infrared light (IR) sensor. A VIS sensor can identify an image by detecting visible light reflected from an image such as a photograph or barcode. An IR sensor can identify a touch by detecting infrared light reflected from a touch such as a finger. The sensor PD may be configured as a photodiode. In some embodiments, the sensor PD may be included only in some unit pixel UPs of the display device.
