Figure 2a and Figure 2b For example Figure 1 The display device 1 is a perspective view stretched in a first direction. Figure 2c For example Figure 1 The display device 1 is a perspective view stretched in the second direction. Figure 2d For example Figure 1 The display device 1 is a perspective view stretched in the first direction and the second direction. Figure 2e For example Figure 1 The display device 1 is a perspective view stretched upwards from a third party.

[0060] refer to 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 predetermined image by emitting light from the pixels. The non-display area NDA may be outside the display area DA. The non-display area NDA is an area in which no pixels are disposed, and 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 an external object or a user. In one embodiment, as... Figure 2a and Figure 2b As illustrated, 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). In one embodiment, for example, as shown... Figure 2a As illustrated, display device 1 can be stretched in the +x and -x directions, or as... Figure 2b As illustrated, while one side of the display device 1 is fixed, the display device 1 can be stretched in the +x direction.

[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 an external object or a user. In one embodiment, as... Figure 2c As illustrated, the display area DA and / or non-display area NDA of the display device 1 can be stretched in the +y and -y directions. In another embodiment, while one side of the display device 1 is fixed, the display device 1 can be stretched in the +y or -y direction.

[0063] The display device 1 can be stretched in multiple directions by an external force applied by an external object or a part of the human body, for example, in a first direction (e.g., +x and / or -x) and a second direction (e.g., +y and / or -y). Figure 2d As illustrated, the display area DA and / or 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 or -z direction) by an external force applied by an external object or a part of the human body. In one embodiment, Figure 2e As an example, a portion of the display device 1, for instance, a portion of the display area DA protrudes in the +z direction. In another embodiment, a portion of the display device 1, for instance, a portion of the display area DA, may protrude upwards in the -z direction (or may be recessed in the +z direction).

[0065] Figures 2a to 2e The display device 1 is illustrated as being stretched in a first direction, a second direction, and / or a third direction, but this disclosure is not limited thereto. In another embodiment, the display device 1 may be deformed into various irregular shapes. For example, in one embodiment, the display device 1 may be bent or twisted relative to two or more axes.

[0066] Figure 3a This is a plan view illustrating one embodiment of the display device 1.

[0067] Multiple pixels can be disposed 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 the sub-pixel may be disposed in the display area DA. A circuit for providing electrical signals to the light-emitting elements disposed in the display area DA and a transistor electrically connected to the light-emitting elements may be disposed in a non-display area NDA surrounding the display area DA. A gate driving circuit GDC may be disposed in a first non-display area NDA1 and a second non-display area NDA2 disposed on opposite sides of the display area DA. The gate driving circuit GDC may include a driver that provides electrical signals to the gate electrode of the transistor electrically connected to the light-emitting element. Although Figure 3a For example, the gate drive circuit GDC is disposed in the first non-display area NDA1 and the second non-display area NDA2, but this disclosure is not limited thereto. In another embodiment, the gate drive circuit GDC may be disposed in the first non-display area NDA1 or the second non-display area NDA2.

[0068] The data drive circuit DDC may be disposed in a third non-display area NDA3 and / or a fourth non-display area NDA4 extending from the first non-display area NDA1 and the second non-display area NDA2. In one embodiment, Figure 3a For example, the data drive circuit DDC is disposed in the fourth non-display area NDA4. In another embodiment, the data drive circuit DDC may be disposed in the third non-display area NDA3 and the fourth non-display area NDA4 respectively.

[0069] although Figure 3a The data drive circuit DDC is exemplified as being disposed in the fourth non-display area NDA4 of the display device 1, but this disclosure is not limited thereto. In another embodiment, the display device 1 may further include a flexible circuit board (not shown) electrically connected via a terminal portion (not shown) disposed in the fourth non-display area NDA4, and the data drive circuit DDC may be disposed on the flexible circuit board.

[0070] In some embodiments, the elongation rate of the non-display area NDA may be less than or equal to the elongation rate of the display area DA. In one embodiment, the elongation rate of the non-display area NDA may be different for each area. For example, in one embodiment, 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 3b This is a plan view illustrating one embodiment of the display device 1.

[0072] refer to Figure 3bThe display device 1 may define a flexible area FA and a hard area HA. ​​The flexible area FA may refer to the flexible area of ​​the display device 1 with a relatively high elongation, and the hard area HA may refer to the hard area of ​​the display device 1 with a relatively low elongation.

[0073] The flexible area FA can be a flexible area that is easily bent, foldable, or stretchable. Compared to the rigid area HA, the flexible area FA can be easily stretched or contracted. In one embodiment, a plurality of openings (not shown) can be defined in the flexible area FA. The openings can be areas in which no element of the display device 1 is disposed. Accordingly, the display device 1 can be easily stretched and / or contracted in various directions.

[0074] The rigid region HA can be a rigid region that is not easily bent. In one embodiment, the rigid region HA can be a region in which no opening (not shown) is provided. Accordingly, the rigid region can be a region in which it is not easily stretched and / or contracted.

[0075] In one embodiment, the data drive circuit DDC may be disposed in the hard region HA. In another embodiment, the display device 1 may further include a flexible circuit board (not shown) electrically connected via a terminal portion (not shown) disposed in the hard region HA, and the data drive circuit DDC may be disposed on the flexible circuit board.

[0076] The flexible area FA may include the display area DA and the non-display area surrounding the display area DA (see reference). Figure 3a The hard region HA may include a portion of the non-display region NDA. For example, in one embodiment, the flexible region FA may include the display region DA, the first to third non-display regions NDA1, NDA2 and NDA3, and a portion of the fourth non-display region NDA4. The hard region HA may include a portion of the fourth non-display region NDA4.

[0077] The flexible area FA may include a display area DA and first to fourth peripheral areas A1, A2, A3, and A4 surrounding the display area DA. For example, in one embodiment, the first peripheral area A1 may be located to the left of the display area DA (e.g., in the -x direction), and the second peripheral area A2 may be located to the right of the display area DA (e.g., in the +x direction). The third peripheral area A3 may be located above the display area DA (e.g., in the +y direction), and the fourth peripheral area A4 may be located below the display area DA (e.g., in the -y direction). The third peripheral area A3 and the fourth peripheral area A4 may be located between the first peripheral area A1 and the second peripheral area A2 in the +x and -x directions, respectively.

[0078] The first peripheral region A1 and the second peripheral region A2 can correspond to the first non-display region NDA1 and the second non-display region NDA2 of the non-display region NDA, and the gate drive circuit (reference) Figure 3a The GDC can be set in the first peripheral area A1 and the second peripheral area A2 respectively.

[0079] Figure 4a An enlarged plan view of one embodiment of region IV of FIG3A, which is part of the display device 1.

[0080] refer to 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) in the display area DA, and first bridging portions 12 extending from adjacent first island portions 11 to each other.

[0081] Each of the first island portions 11 may extend to a plurality of first bridging portions 12. For example, in one embodiment, each of the first island portions 11 may extend to four first bridging portions 12. Two first bridging portions 12 may be respectively disposed on opposite sides of the first island portion 11 in a first direction (e.g., +x direction or -x direction), and the remaining two first bridging portions 12 may be respectively disposed on opposite sides of the first island portion 11 in a second direction (e.g., +y direction or -y direction). In one embodiment, the four first bridging portions 12 may extend to the four sides of the first island portion 11. The four first bridging portions 12 may be adjacent to the corners of the first island portion 11.

[0082] The first bridging portions 12 may be spaced apart from each other by first openings CS1 between the first bridging portions 12. In one embodiment, first openings CS1 having an approximate H shape and first openings CS1 having an approximate I shape obtained by rotating the H shape by 90 degrees may be alternately and repeatedly arranged in a first direction (e.g., +x direction or -x direction) and a second direction (e.g., +y direction or -y direction). The two end portions of each of the first bridging portions 12 may extend to the adjacent first island portion 11 respectively, and one side of each of the first bridging portions 12 may be spaced apart from one side of the adjacent first island portion 11 and / or one side of the other first bridging portion 12 by the first openings CS1.

[0083] The display device 1 may include a non-display area (e.g., ...). Figure 4a The second island portions 21 spaced apart from each other in the first non-display area NDA1 (illustrated in the image) and the second bridging portions 22 extending to the adjacent second island portions 21.

[0084] Each of the second island portions 21 may extend in a first direction (e.g., the +x direction or the -x direction). The second island portions 21 may be spaced apart from each other in 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). The second island portions 21 may include a driver for a gate drive circuit (refer to the GDC of FIG3A) described with reference to FIG3A.

[0085] 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 in a second direction (e.g., the +y direction or the -y direction). In one embodiment, the second bridging portion 22 may have an approximately omega (Ω) shape that protrudes in a first direction (e.g., the +x direction or the -x direction). The second bridging portions 22 may be between adjacent second island portions 21 and may be spaced apart from each other.

[0086] Second bridging portions 22 between adjacent second island portions 21 may be spaced apart from each other by second openings CS2. The second openings CS2 and second bridging portions 22 may be alternately arranged between adjacent second island portions 21 in a first direction (e.g., +x or -x direction). The second openings CS2 may have the same shape. Both end portions of each of the second bridging portions 22 may extend to an adjacent second island portion 21, and one side of each of the second bridging portions 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 the second openings CS2.

[0087] A second island portion 21 disposed in the first non-display area NDA1 may correspond to multiple rows of first island portions 11 disposed in the display area DA. For example, in one embodiment, a second island portion 21 disposed in the first non-display area NDA1 may correspond to a first island portion 11 disposed in the i-th row and a first island portion 11 disposed in the (i+1)-th row (where i is a positive number greater than 0) in the display area DA. Although Figure 4a An example is given of a second island portion 21 corresponding to two rows of first island portions 11, but this disclosure is not limited thereto. In another embodiment, a second island portion 21 disposed in the first non-display area NDA1 may correspond to n rows of first island portions 11 disposed in the display area DA (where n is a positive number greater than or equal to 3).

[0088] The non-display area, for example, a 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 arranged, 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 may be disposed in the second sub-non-display area SNDA2 and extend to the display area DA and the first sub-non-display area SNDA1. One end portion of the third bridging portion 23 may extend to the second island portion 21 and / or the second bridging portion 22, and the opposite end portion of the third bridging portion 23 may extend to the first island portion 11 and / or the first bridging portion 12.

[0089] The third bridging portion 23 may have a serpentine shape. In one embodiment, the shape of the third bridging portion 23 may differ from the shape of the first bridging portion 12 and the shape of the second bridging portion 22. In one embodiment, such as... Figure 4a As illustrated, the third bridging portion 23 may have an approximately omega (Ω) shape protruding in a second direction (e.g., the +y or -y direction). The third bridging portion 23 may have a symmetrical structure, wherein one of adjacent third bridging portions 23 disposed in the second direction (e.g., the +y or -y direction) protrudes in the +y direction, and the other protrudes in the -y direction. A third opening CS3 and a fourth opening CS4 having different shapes from each other may be repeated 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 one embodiment, the width of the third bridging portion 23 may be greater than the width of the first bridging portion 12 and less than the width of the second bridging portion 22.

[0090] Figure 4a For example, in a non-display area, the second island portion 21 and the second bridging portion 22 in the first non-display area NDA1 have different shapes than the first island portion 11 and the first bridging portion 12 in the display area DA. In another embodiment, the second island portion 21 and the second bridging portion 22 in the non-display area may each have the same shape as the first island portion 11 and the first bridging portion 12 in the display area DA.

[0092] refer to Figure 4b The display device 1 may include first island portions 11 spaced apart from each other in the display area DA and first bridging portions 12 spaced apart from each other through a first opening CS1 and connecting adjacent first island portions 11 to each other. Figure 4b The structure of the display area DA in the reference can be compared with that of the reference. Figure 4a The structure of the described display area DA is the same.

[0093] The display device 1 may include a second island portion 21 and a second bridging portion 22 disposed in a non-display area, for example, a first non-display area NDA1. In one embodiment, the second island portion 21 and the second bridging portion 22 may each have a shape substantially the same as that of the first island portion 11 and the first bridging portion 12.

[0094] The second island portions 21 may be spaced apart from each other in a first direction (e.g., +x or -x direction) and a second direction (e.g., +y or -y direction) in a non-display area, such as a first non-display area NDA1. Second bridging portions 22 may each connect adjacent second island portions 21 to each other. The second bridging portions 22 may be spaced apart from each other by a second opening CS2 between the second bridging portions 22.

[0095] The second opening CS2 may have a shape substantially the same as that of the first opening CS1. In one embodiment, the approximately H-shaped second opening CS2 and the approximately I-shaped second opening CS2 may be alternately and repeatedly disposed in a non-display area, for example, a first non-display area NDA1.

[0161] although Figure 7b The first semiconductor layer 231 is illustrated as a p-type semiconductor layer and the second semiconductor layer 232 as an n-type semiconductor layer, but this disclosure is not limited thereto. In another embodiment, the first semiconductor layer 231 may include an n-type semiconductor layer and the second semiconductor layer 232 may include a p-type semiconductor layer.

Figure 10 and Figure 11 An enlarged plan view of another embodiment of the display device 1 is shown as an example, and an example is given. Figure 8b A variant of .

[0163] refer to Figure 8aA first peripheral area A1, a second peripheral area A2, and a third peripheral area A3 may be disposed around the display area DA. An intermediate area BA may be disposed between the first peripheral area A1, the second peripheral area A2, and the third peripheral area A3. The intermediate area BA may be included within the non-display area NDA. The intermediate area BA may include a first intermediate area B1, a second intermediate area B2, a third intermediate area B3, a fourth intermediate area B4, and a fifth intermediate area B5. The first intermediate area B1 may be disposed between the display area DA and the first peripheral area A1. The second intermediate area B2 may be disposed between the display area DA and the second peripheral area A2. The third intermediate area B3 may be disposed between the display area DA and the third peripheral area A3. The fourth intermediate area B4 may be disposed between the first peripheral area A1 and the third peripheral area A3. The fifth intermediate area B5 may be disposed between the third peripheral area A3 and the second peripheral area A2. Bridging portions and / or openings, as described below, may be disposed within the intermediate area BA.

[0164] refer to Figure 8a and Figure 8b The display device 1 may include, within the display area DA, main island portions D11 spaced apart from each other and arranged in a matrix in a first direction (e.g., +x or -x) and a second direction (e.g., +y or -y), and main bridging portions D12 connecting adjacent main island portions D11 to each other. The main bridging portions D12 may be spaced apart from each other by main openings D13 between the main bridging portions D12.

[0165] In one embodiment, Figure 8b The structure of the display area DA in the reference can be compared with that of the reference. Figure 4c The structure of the described display area DA is the same. For example, in one embodiment, the main island portion D11, the main bridging portion D12, and the main opening D13 in the display area DA may be the same as those in the reference. Figure 4c The first island portion 11, the first bridging portion 12, and the first opening CS1 in the described display area DA correspond to each other.

[0166] The main bridging portion D12 may have a serpentine shape. For example, in one embodiment, the main bridging portion D12 may have an approximately S-shape. The main island portion D11 may extend to the main bridging portions D12 respectively. For example, in one embodiment, the main island portion D11 may each extend to two main bridging portions D12 disposed on opposite sides of the main island portion D11 in a first direction (e.g., +x direction or -x direction) and two main bridging portions D12 disposed on opposite sides of the main island portion D11 in a second direction (e.g., +y direction or -y direction). The four main bridging portions D12 may be adjacent to the corners of the main island portion D11.

[0167] The display device 1 may include first peripheral island portions A11 spaced apart from each other in a first peripheral region A1 and arranged in a matrix in a first direction (e.g., +x or -x) and a second direction (e.g., +y or -y). It may also include first peripheral bridging portions A12 connecting adjacent first peripheral island portions A11 to each other. The first peripheral bridging portions A12 may be spaced apart from each other by first peripheral openings A13 disposed between the first peripheral island portions A11.

[0168] In one embodiment, Figure 8b The structure of the first outer region A1 in the reference can be compared with that of the reference. Figure 4c The structure of the first non-display area NDA1 described is the same. For example, in one embodiment, the first peripheral island portion A11, the first peripheral bridging portion A12, and the first peripheral opening A13 in the first peripheral area A1 may be the same as those in the reference. Figure 4c The second island portion 21, the second bridging portion 22, and the second opening CS2 in the first non-display area NDA1 (e.g., the first sub-non-display area SNDA1) are described.

[0169] The first peripheral bridging portion A12 may have a serpentine shape. For example, in one embodiment, the first peripheral bridging portion A12 may have an approximately S-shaped shape. The first peripheral bridging portions A12 may extend to the first peripheral island portion A11, respectively. For example, in one embodiment, the first peripheral island portion A11 may each extend to two first peripheral bridging portions A12 disposed on opposite sides of the first peripheral island portion A11 in a first direction (e.g., +x direction or -x direction) and two first peripheral bridging portions A12 disposed on opposite sides of the first peripheral island portion A11 in a second direction (e.g., +y direction or -y direction). The four first peripheral bridging portions A12 may each extend to the central portion of each side of the first peripheral island portion A11.

[0170] The display device 1 may include second peripheral island portions A21 spaced apart from each other and second peripheral bridging portions A22 connecting adjacent second peripheral island portions A21 to each other in the second peripheral area A2. The second peripheral bridging portions A22 may be spaced apart from each other by second peripheral openings A23 provided between the second peripheral island portions A21.

[0171] The second peripheral bridging portion A22 may have a serpentine shape. For example, in one embodiment, the second peripheral bridging portion A22 may have a shape that is an approximate S-shape reversed left and right. The second peripheral bridging portions A22 may extend to the second peripheral island portion A21 respectively. For example, in one embodiment, the second peripheral island portion A21 may each extend to two second peripheral bridging portions A22 disposed on opposite sides of the second peripheral island portion A21 in a first direction (e.g., +x direction or -x direction) and two second peripheral bridging portions A22 disposed on opposite sides of the second peripheral island portion A21 in a second direction (e.g., +y direction or -y direction). The four second peripheral bridging portions A22 may each extend to the central portion of each side of the second peripheral island portion A21.

[0172] The first peripheral area A1 and the second peripheral area A2 may have a symmetrical structure with respect to the center line IA. The center line IA may be located between the first peripheral area A1 and the second peripheral area A2, and may be located at the same distance from the first peripheral area A1 and the second peripheral area A2. The center line IA may pass through the center of the display area DA and may extend in a second direction (e.g., the +y direction or the -y direction). Specifically, the first peripheral island portion A11 of the first peripheral area A1 and the second peripheral island portion A21 of the second peripheral area A2 may be symmetrically arranged with respect to the center line IA. The first peripheral bridging portion A12 of the first peripheral area A1 and the second peripheral bridging portion A22 of the second peripheral area A2 may be symmetrically arranged with respect to the center line IA.

[0173] The second outer island portion A21 and the first outer island portion A11 may have symmetrical shapes relative to the center line IA. The second outer bridging portion A22 and the first outer bridging portion A12 may also have symmetrical shapes relative to the center line IA. For example, in one embodiment, the first outer bridging portion A12 may have an approximate S-shape, and the second outer bridging portion A22 may have a shape that is a left-right reversal of the approximate S-shape.

[0174] In some embodiments, as referenced Figure 3a The gate drive circuit may be disposed in a first peripheral region A1 and a second peripheral region A2. At least some first peripheral island portions A11 in the first peripheral region A1 may include drive units of the gate drive circuit disposed on the left side. A first peripheral bridging portion A12 may include wiring electrically connected to the drive units of adjacent first peripheral island portions A11. Additionally, at least some second peripheral island portions A21 in the second peripheral region A2 may include drive units of the gate drive circuit disposed on the right side. A second peripheral bridging portion A22 may include wiring electrically connected to the drive units of adjacent second peripheral island portions A21.

[0175] The gate drive circuit may include multiple stages, each outputting a gate signal. Each stage may output gate signals sequentially based on a control signal. Each drive unit may include at least one stage. The drive unit may include a node controller and a buffer transistor. The node controller may include multiple transistors and multiple capacitors, and may control the voltage of the node via a start signal provided via an input terminal, etc. The buffer transistor may be configured to isolate the signal source from the circuitry driven by the signal source. Additionally, the wiring connected to the gate drive circuit may be signal lines providing electrical signals to the gate drive circuit and / or voltage lines providing voltage to the gate drive circuit. For example, these wirings may correspond to clock wiring providing a clock signal to the gate drive circuit, gate high voltage wiring applying a drive voltage, and gate low voltage wiring.

[0176] The drive unit included in the first peripheral island portion A11 and the drive unit included in the second peripheral island portion A21 are symmetrically arranged with respect to the center line IA. The wiring included in the first peripheral bridging portion A12 and the wiring included in the second peripheral bridging portion A22 are symmetrically arranged with respect to the center line IA.

[0177] refer to Figure 9 For example, the first peripheral island portion A11 in region A may include a first driving unit GDU1, and the first driving unit GDU1 may include a node controller NC and a buffer transistor BF. The second peripheral island portion A21 in region B may include a second driving unit GDU2, and the second driving unit GDU2 may include a node controller NC' and a buffer transistor BF'. The first driving unit GDU1 and the second driving unit GDU2 may be symmetrically arranged with respect to the center line IA. For example, in one embodiment, in the first driving unit GDU1, the node controller NC may be located on the upper left side, and the buffer transistor BF may be located on the upper right side. In the second driving unit GDU2, the node controller NC' may be located on the upper right side, and the buffer transistor BF' may be located on the upper left side.

[0178] Additionally, the first peripheral bridging portion A12, extending to the left side of the first peripheral island portion A11 in region A, may include a first wiring L1 electrically connected to the first drive unit GDU1. The second peripheral bridging portion A22, extending to the right side of the second peripheral island portion A21 in region B, may include a second wiring L2 electrically connected to the second drive unit GDU2. The first wiring L1 of the first peripheral bridging portion A12 and the second wiring L2 of the second peripheral bridging portion A22 may be symmetrically arranged with respect to the centerline IA.

[0179] refer to Figure 9The first peripheral bridging portion A12 and the second peripheral bridging portion A22 may each have a serpentine shape. Because pressure (strain) can be applied inside the bending portion, there may be areas where wiring cannot be formed (refer to F and G). That is, the first peripheral bridging portion A12 and the second peripheral bridging portion A22 may have areas in which wiring designs are possible (e.g., F and G). Figure 9 As illustrated, the area where wiring may be designed can vary depending on the bending direction in the shape of the bridging section.

[0180] In the comparative example, when the first island portion of the first peripheral region and the second island portion of the second peripheral region are not symmetrically arranged with respect to the center line, or when the first peripheral bridging portion of the first peripheral region and the second peripheral bridging portion of the second peripheral region are not symmetrically arranged with respect to the center line, the drive units and wiring in the first peripheral region and the drive units and wiring in the second peripheral region can be designed differently, and the deviation can occur between the output of the gate drive circuit in the first peripheral region and the output of the gate drive circuit in the second peripheral region.

[0181] In one embodiment, when the drive units included in the first peripheral island portion and the drive units included in the second peripheral island portion are symmetrically arranged, and the first peripheral bridging portion and the second peripheral bridging portion are formed to have the same shape while performing a reverse design to symmetrically arrange the wiring included in the first peripheral bridging portion and the wiring included in the second peripheral bridging portion, for example, the wiring of the first peripheral bridging portion and the wiring of the second peripheral bridging portion can be designed differently due to the area limitations in which wiring design may be performed due to the shape of the bridging portion. Accordingly, the drive units of the first peripheral island portion and the drive units of the second peripheral island portion can also be designed differently. In this case, due to the different designs between the drive units and wiring in the first peripheral area and the drive units and wiring in the second peripheral area, a deviation may occur between the output of the gate drive circuit in the first peripheral area and the output of the gate drive circuit in the second peripheral area.

[0182] However, in one embodiment, the first peripheral island portion A11 of the first peripheral region A1 and the second peripheral island portion A21 of the second peripheral region A2 may be symmetrically arranged with respect to the center line IA, and the first peripheral bridging portion A12 of the first peripheral region A1 and the second peripheral bridging portion A22 of the second peripheral region A2 may also be symmetrically arranged with respect to the center line IA. Specifically, the drive unit included in the first peripheral island portion A11 and the drive unit included in the second peripheral island portion A21 may be symmetrically arranged with respect to the center line IA, and the second peripheral island portion A21 and the first peripheral island portion A11 may have symmetrical shapes with respect to the center line IA. The wiring included in the first peripheral bridging portion A12 and the wiring included in the second peripheral bridging portion A22 may be symmetrically arranged with respect to the center line IA. The second peripheral island portion A21 and the first peripheral island portion A11 may have symmetrical shapes. In this case, the drive unit and wiring in the first peripheral region A1 and the drive unit and wiring in the second peripheral region A2 may be designed to be identical to each other. Accordingly, the deviation between the output of the gate drive circuit in the first peripheral region A1 and the output of the gate drive circuit in the second peripheral region A2 can be eliminated.

[0183] Return to reference Figure 8a and Figure 8b The display device 1 may include third peripheral island portions A31 spaced apart from each other and third peripheral bridging portions A32 connecting adjacent third peripheral island portions A31 to each other in the third peripheral area A3. The third peripheral bridging portions A32 may be spaced apart from each other by third peripheral openings A33 provided between the third peripheral island portions A31.

[0184] In one embodiment, such as Figure 8b As illustrated, the structure of the third peripheral region A3 may be the same as that of the first peripheral region A1. The arrangement of the third peripheral island portion A31, the third peripheral bridging portion A32, and the third peripheral opening A33 in the third peripheral region A3 may be substantially the same as the arrangement of the first peripheral island portion A11, the first peripheral bridging portion A12, and the first peripheral opening A13 in the first peripheral region A1. Furthermore, the third peripheral island portion A31, the third peripheral bridging portion A32, and the third peripheral opening A33 in the third peripheral region A3 may each have a shape substantially the same as that of the first peripheral island portion A11, the first peripheral bridging portion A12, and the first peripheral opening A13 in the first peripheral region A1. For example, in one embodiment, the third peripheral bridging portion A32 may have the same shape as the first peripheral bridging portion A12. The third peripheral bridging portion A32 may have a serpentine shape. For example, in one embodiment, the third peripheral bridging portion A32 may have an approximately S-shaped appearance.

[0185] However, this disclosure is not limited thereto. In another embodiment, such as Figure 10As illustrated, the structure of the third peripheral region A3 may be the same as that of the second peripheral region A2. The arrangement of the third peripheral island portion A31, the third peripheral bridging portion A32, and the third peripheral opening A33 in the third peripheral region A3 may be substantially the same as the arrangement of the second peripheral island portion A21, the second peripheral bridging portion A22, and the second peripheral opening A23 in the second peripheral region A2. Furthermore, the third peripheral island portion A31, the third peripheral bridging portion A32, and the third peripheral opening A33 in the third peripheral region A3 may each have a shape substantially the same as that of the second peripheral island portion A21, the second peripheral bridging portion A22, and the second peripheral opening A23 in the second peripheral region A2. For example, in one embodiment, the third peripheral bridging portion A32 may have the same shape as the second peripheral bridging portion A22. The third peripheral bridging portion A32 may have a serpentine shape. For example, in one embodiment, the third peripheral bridging portion A32 may have a shape that is an approximate S-shape reversed left and right.

[0186] At least some of the third peripheral island portion A31 and the third peripheral bridging portion A32 in the third peripheral region A3 may be dummy island portions or dummy bridging portions that do not include drive circuitry or wiring. Some of the third peripheral island portion A31 and the third peripheral bridging portion A32 may include wiring. For example, in one embodiment, some of the third peripheral island portion A31 and the third peripheral bridging portion A32 may include wiring connected to gate drive circuitry disposed in the first peripheral region A1 or the second peripheral region A2.

[0187] The bridging portion may be located in the intermediate area BA. The first intermediate bridging portion B12 may be located in the first intermediate area B1 and extend to the display area DA and the first peripheral area A1. One end portion of the first intermediate bridging portion B12 may extend to the first peripheral island portion A11 and / or the first peripheral bridging portion A12, and the opposite end portion of the first intermediate bridging portion B12 may extend to the main island portion D11 and / or the main bridging portion D12.

[0188] In one embodiment, Figure 8b The structure of the first intermediate region B1 in the reference can be compared with that of the reference. Figure 4c The structure of the second sub-non-display area SNDA2 is the same as described. For example, in one embodiment, the first intermediate bridging portion B12 of the first intermediate area B1 may be the same as the reference. Figure 4c The third bridging portion 23 of the second sub-display area SNDA2 described corresponds to this.

[0189] The first intermediate bridging portion B12 may have a serpentine shape. In one embodiment, the shape of the first intermediate bridging portion B12 may differ from the shape of the main bridging portion D12 and the shape of the first peripheral bridging portion A12. The width of the first intermediate bridging portion B12 may differ from the width of the main bridging portion D12 and / or the width of the first peripheral bridging portion A12. For example, in one embodiment, the width of the first intermediate bridging portion B12 may be greater than the width of the main bridging portion D12 and less than the width of the first peripheral bridging portion A12. The first-1 intermediate opening B13a and the first-2 intermediate opening B13b, which have different shapes, may alternate between the first intermediate bridging portions B12 in a second direction (e.g., the +y direction or the -y direction).

[0190] The second intermediate bridging portion B22 may be disposed in the second intermediate area B2 and extend to the display area DA and the second peripheral area A2. One end portion of the second intermediate bridging portion B22 may extend to the second peripheral island portion A21 and / or the second peripheral bridging portion A22, and the opposite end portion of the second intermediate bridging portion B22 may extend to the main island portion D11 and / or the main bridging portion D12.

The width of the second intermediate bridging portion B22 may differ from the width of the main bridging portion D12 and / or the width of the first peripheral bridging portion A12. For example, in one embodiment, the width of the second intermediate bridging portion B22 may be greater than the width of the main bridging portion D12 and less than the width of the first peripheral bridging portion A12. For example, a second-1 intermediate opening B23a and a second-2 intermediate opening B23b with different shapes may alternate between the second intermediate bridging portions B22 in a second direction (e.g., the +y direction or the -y direction).

[0192] The third intermediate bridging portion B32 may be disposed in the third intermediate area B3 and extend to the display area DA and the third peripheral area A3.

The width of the third intermediate bridging portion B32 may differ from the width of the main bridging portion D12 and / or the width of the third peripheral bridging portion A32. For example, in one embodiment, the width of the third intermediate bridging portion B32 may be greater than the width of the main bridging portion D12 and equal to the width of the third peripheral bridging portion A32. The third-1 intermediate opening B33a and the third-2 intermediate opening B33b, which have different shapes, may alternate between the third intermediate bridging portions B32 in a first direction (e.g., the +x direction or the -x direction). The third-3 intermediate opening B33c, which has a shape different from the third-1 intermediate opening B33a and the third-2 intermediate opening B33b, may be provided at the two end portions of the third intermediate region B3 in the first direction (e.g., the +x direction or the -x direction).

One end portion of the fourth intermediate bridging portion B42 may extend to the first peripheral island portion A11 and / or the first peripheral bridging portion A12, and the opposite end portion of the fourth intermediate bridging portion B42 may extend to the third peripheral island portion A31 and / or the third peripheral bridging portion A32.

[0195] The fourth intermediate bridging portion B42 may have a serpentine shape. In one embodiment, such as... Figure 8b As illustrated, the shape of the fourth intermediate bridging portion B42 may differ from the shapes of the first peripheral bridging portion A12 and the third peripheral bridging portion A32. However, this disclosure is not limited thereto. In another embodiment, such as Figure 11 As illustrated, the shape of the fourth intermediate bridging portion B42 may be substantially the same as the shape of the first peripheral bridging portion A12 and / or the shape of the third peripheral bridging portion A32.

However, this disclosure is not limited thereto. In another embodiment, the width of the fourth intermediate bridging portion B42 may be different from the width of the first peripheral bridging portion A12 and / or the width of the third peripheral bridging portion A32. A fourth-1 intermediate opening B43a and a fourth-2 intermediate opening B43b, having different shapes, may alternately lie between the fourth intermediate bridging portions B42 in a second direction (e.g., the +y direction or the -y direction).

[0197] The fifth intermediate bridging portion B52 may be disposed in the fifth intermediate region B5 and extend to the second outer perimeter region A2 and the third outer perimeter region A3.

Figure 12a and Figure 12b for Figure 8a and Figure 8b This is a variation of the previous embodiment, and the difference between this variation and the previous embodiment lies in the structure of the display area DA, the third peripheral area A3, and the intermediate area BA. The differences are described below, and repeated descriptions are omitted. Figure 13 As part of display device 1 Figure 12b An enlarged plan view of one embodiment of regions C and D.

The third peripheral area A3 may include the first sub-area A3-1 and the second sub-area A3-2, with the center line between the first sub-area A3-1 and the second sub-area A3-2.

The intermediate zone BA may include a first intermediate zone B1, a second intermediate zone B2, a third intermediate zone B3, a fourth intermediate zone B4, a fifth intermediate zone B5, a first central zone M1, and a second central zone M2. The first central zone M1 can be located between the first display zone DA-1 and the second display zone DA-2.

The third intermediate zone B3 may include the first sub-zone B3-1 and the second sub-zone B3-2 located on opposite sides of the center line IA, respectively. Bridging portions and / or openings may be provided within the intermediate zone BA.

Although Figure 12b An example is shown with 12 rows of main island portions D11 arranged in the display area DA, but this disclosure is not limited thereto. For example, in one embodiment, 13 or more rows of main island portions D11 may be arranged in the display area DA.

[0203] The main island portion D11 located in the first display area DA-1 can be the first main island portion D11-1, and the main island portion D11 located in the second display area DA-2 can be the second main island portion D11-2. The main bridging portion D12 located in the first display area DA-1 can be the first main bridging portion D12-1, and the main bridging portion D12 located in the second display area DA-2 can be the second main bridging portion D12-2. The main opening D13 located in the first display area DA-1 can be the first main opening D13-1, and the main opening D13 located in the second display area DA-2 can be the second main opening D13-2.

[0204] The first main island section D11-1 and the second main island section D11-2 can be symmetrically arranged with respect to the centerline IA. The first main bridging section D12-1 and the second main bridging section D12-2 can be symmetrically arranged with respect to the centerline IA.

The first main bridging portion D12-1 and the second main bridging portion D12-2 may also have symmetrical shapes with respect to the center line IA. In one embodiment, the first main bridging portion D12-1 may have an approximate S-shape, and the second main bridging portion D12-2 may have a shape that is a left-right reversal of the approximate S-shape.

[0206] As referenced above Figure 5 The main island portion D11 may each include a light-emitting element constituting a pixel and circuitry (e.g., a pixel driving circuit) electrically connected to and driving the light-emitting element. The pixel driving circuitry may include a transistor and at least one capacitor. The main bridge portion D12 may include wiring electrically connected to the pixel driving circuitry arranged in the adjacent main island portion D11. The wiring electrically connected to the pixel driving circuitry may be signal lines (e.g., gate lines, data lines, etc.) providing electrical signals to the transistors included in the pixel driving circuitry, or voltage lines (e.g., drive voltage lines, initialization voltage lines, etc.) providing voltage to the transistors included in the pixel driving circuitry.

[0207] The pixel driving circuits included in the first main island portion D11-1 and the second main island portion D11-2 are symmetrically arranged with respect to the center line IA. The wiring included in the first main bridging portion D12-1 and the wiring included in the second main bridging portion D12-2 are symmetrically arranged with respect to the center line IA.
