[0078] The first peripheral area (A1) and the second peripheral area (A2) correspond to the first non-display area (NDA1) and the second non-display area (NDA2) of the non-display area (NDA), and a gate driving circuit (GDC, see FIG. 3a) can be arranged in each of them.

[0079] FIG. 4A is an enlarged plan view of part IV of FIG. 3A as part of a display device (1) according to one embodiment of the present invention.

[0080] Referring to FIG. 4a, the display device (1) may include first island portions (11) spaced apart from each other along a first direction (e.g., +x direction or -x direction) and a second direction (e.g., +y direction or -y direction) in a display area (DA), and first bridge portions (12) extending from adjacent first island portions (11).

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

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

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

Each second island portion (21) may include drivers of a gate drive circuit (GDC, see FIG. 3A) described with reference to FIG. 3A.

[0085] The second bridge portion (22) may have a serpentine shape. The length of the second bridge portion (22) may be greater than the shortest distance between adjacent second island portions (21) along the second direction (e.g., +y direction or -y direction). In one embodiment, the second bridge portion (22) may have a shape of approximately omega (Ω) that is convex toward the first direction (e.g., +x direction or -x direction). The second bridge portions (22) may be arranged between adjacent second island portions (21), but may be spaced apart from each other.

[0086] The second bridge portions (22) between adjacent second island portions (21) can be spaced apart from each other by the second opening portions (CS2). Between the adjacent second island portions (21), the second opening portions (CS2) and the second bridge portions (22) can be alternately arranged along the first direction (e.g., +x direction or -x direction). The second opening portions (CS2) can have the same shape. Both ends of each second bridge portion (22) extend to the adjacent second island portions (21), but one side of each second bridge portion (22) can be spaced apart from the side of the adjacent second island portion (21) and / or one side of another second bridge portion (22) by the second opening portion (CS2).

[0087] Any one of the second island portions (21) arranged in the first non-display area (NDA1) may correspond to the first island portions (11) of a plurality of rows arranged in the display area (DA). In one embodiment, any one of the second island portions (21) arranged in the first non-display area (NDA1) may correspond to the first island portions (11) arranged in the (i)-th row and the first island portions (11) arranged in the (i+1)-th row in the display area (DA) (wherein, i is a positive number greater than 0). For example, FIG. 4A illustrates that one second island portion (21) corresponds to two rows of the first island portions (11), but the present invention is not limited thereto. In another embodiment, any one of the second island portions (21) arranged in the first non-display area (NDA1) may correspond to n rows of the first island portions (11) arranged in the display area (DA) (where n is a positive integer greater than or equal to 3).

[0088] A non-display area, for example, a first non-display area (NDA1), may include a first sub-non-display area (SNDA1) in which the second island portions (21) and second bridge portions (22) described above are arranged, and a second sub-non-display area (SNDA2) between the first sub-non-display area (SNDA1) and the display area (DA).

[0151] Referring to FIG. 7A, a light-emitting element according to one embodiment of the present invention may include an organic light-emitting diode (220) including an organic material. The organic light-emitting diode (220) may include a first electrode (221) disposed on an insulating layer, a second electrode (225) facing the first electrode (221), and a light-emitting layer (223) interposed between the first electrode (221) and the second electrode (225).

Alternatively, the second electrode (225) may further include a layer such as ITO, IZO, ZnO, AZO, or In2O3 on the (semi-)transparent layer including the aforementioned material.

[0156] FIG. 7b is a cross-sectional view schematically showing a light-emitting element of a display device according to one embodiment of the present invention.

[0157] Referring to FIG. 7b, in one embodiment of the present invention, a light-emitting element may include an inorganic light-emitting diode (230) including an inorganic material. The inorganic light-emitting diode (230) may include a first semiconductor layer (231), a second semiconductor layer (232), an intermediate layer (233) between the first semiconductor layer (231) and the second semiconductor layer (232), a first electrode (235) electrically connected to the first semiconductor layer (231), and a second electrode (238) electrically connected to the second semiconductor layer (232). The first electrode (235) and the second electrode (238) of the inorganic light-emitting diode (230) may be electrically connected to a first electrode pad (241) and a second electrode pad (242), respectively, which are disposed on the same layer.

[0158] In some embodiments, the first semiconductor layer (231) may include a p-type semiconductor layer. The p-type semiconductor layer may be selected from semiconductor materials having a composition formula of InxAlyGa1-x-yN (0≤x≤1, 0≤y≤1, 0≤x+y≤1), such as GaN, AlN, AlGaN, InGaN, InN, InAlGaN, AlInN, etc., and may be doped with a p-type dopant such as Mg, Zn, Ca, Sr, or Ba.

[0160] The intermediate layer (233) is a region where electrons and holes recombine, and as the electrons and holes recombine, they transition to a relatively low energy level, and light having a corresponding wavelength can be generated. In one embodiment, the intermediate layer (233) may be formed by including, for example, a semiconductor material having a composition formula of InxAlyGa1-x-yN (0≤x≤1, 0≤y≤1, 0≤x+y≤1), and may be formed as a single quantum well structure or a multi-quantum well structure (MQW). In addition, it may also include a quantum wire structure or a quantum dot structure.

[0161] Although Fig. 7b illustrates that the first semiconductor layer (231) includes a p-type semiconductor layer and the second semiconductor layer (232) includes an n-type semiconductor layer, the present invention 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.

FIGS. 8A and 8B are enlarged views of portion V of FIG. 3B. FIG. 9 is a plan view showing an enlarged portion of portion A and portion B of FIG. 8B as a portion of a display device (1) according to one embodiment of the present invention. FIGS. 10 and 11 are plan views showing an enlarged portion of a portion of a display device (1) according to another embodiment of the present invention, and illustrate a modified embodiment of FIG. 8B.

[0163] Referring to FIG. 8A, a first peripheral area (A1), a second peripheral area (A2), and a third peripheral area (A3) may be arranged around a display area (DA). An intermediate area (BA) may be arranged between each area. The intermediate area (BA) may be included in a 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 arranged between the display area (DA) and the first peripheral area (A1). The second intermediate area (B2) may be arranged between the display area (DA) and the second peripheral area (A2). The third intermediate area (B3) may be arranged between the display area (DA) and the third peripheral area (A3). The fourth intermediate region (B4) may be positioned between the first peripheral region (A1) and the third peripheral region (A3). The fifth intermediate region (B5) may be positioned between the third peripheral region (A3) and the second peripheral region (A2). A bridge portion and / or an opening portion, which will be described later, may be positioned in the intermediate region (BA).

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

[0165] In one embodiment, the structure of the display area (DA) of FIG. 8B may be the same as the structure of the display area (DA) described with reference to FIG. 4C. For example, the main island portion (D11), the main bridge portion (D12), and the main opening portion (D13) of the display area (DA) may correspond to the first island portion (11), the first bridge portion (12), and the first opening portion (CS1) of the display area (DA) described with reference to FIG. 4C.

[0166] The main bridge portion (D12) may have a winding shape. For example, the main bridge portion (D12) may have a shape roughly like the letter 'S'. Each of the main island portions (D11) may extend to a plurality of main bridge portions (D12). For example, each main island portion (D11) may extend to two main bridge portions (D12) arranged on both sides of the main island portion (D11) along a first direction (e.g., +x direction or -x direction) and two main bridge portions (D12) arranged on both sides of the main island portion (D11) along a second direction (e.g., +y direction or -y direction). Each of the four main bridge portions (D12) may be adjacent to each corner of the main island portion (D11).

[0167] The display device (1) may be arranged in a matrix along a first direction (e.g., +x direction or -x direction) and a second direction (e.g., +y direction or -y direction) in a first peripheral area (A1), and may include first peripheral island portions (A11) spaced apart from each other and first peripheral bridge portions (A12) extending to adjacent first peripheral island portions (A11). The first peripheral bridge portions (A12) may be spaced apart from each other by first peripheral opening portions (A13) located between the first peripheral island portions (A11).

[0168] In one embodiment, the structure of the first peripheral area (A1) of FIG. 8B may be the same as the structure of the first non-display area (NDA1) described above with reference to FIG. 4C. For example, the first peripheral island portion (A11), the first peripheral bridge portion (A12), and the first peripheral opening portion (A13) of the first peripheral area (A1) may correspond to the second island portion (21), the second bridge portion (22), and the second opening portion (CS2) of the first non-display area (NDA1) (e.g., the first sub-non-display area (SNDA1)) described with reference to FIG. 4C.

[0169] The first peripheral bridge portion (A12) may have a meandering shape. For example, the first peripheral bridge portion (A12) may have a shape roughly like the letter 'S'. Each of the first peripheral bridge portions (A12) may extend to a plurality of first peripheral island portions (A11). For example, each first peripheral island portion (A11) may extend to two first peripheral bridge portions (A12) arranged on both sides of the first peripheral island portion (A11) along a first direction (e.g., +x direction or -x direction) and to two first peripheral bridge portions (A12) arranged on both sides of the first peripheral island portion (A11) along a second direction (e.g., +y direction or -y direction). Each of the four first peripheral bridge portions (A12) may 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 in a second peripheral area (A2) and second peripheral bridge portions (A22) extending to adjacent second peripheral island portions (A21). The second peripheral bridge portions (A22) may be spaced apart from each other by second peripheral opening portions (A23) positioned between the second peripheral island portions (A21).

[0171] The second peripheral bridge portion (A22) may have a winding shape. For example, the second peripheral bridge portion (A22) may have a shape roughly similar to the letter S, which is flipped left and right. Each of the second peripheral bridge portions (A22) may extend to a plurality of second peripheral island portions (A21). For example, each second peripheral island portion (A21) may extend to two second peripheral bridge portions (A22) arranged on both sides of the second peripheral island portion (A21) along a first direction (e.g., +x direction or -x direction) and to two second peripheral bridge portions (A22) arranged on both sides of the second peripheral island portion (A21) along a second direction (e.g., +y direction or -y direction). Each of the four second peripheral bridge portions (A22) may 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) is 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 extend along the second direction (e.g., +y direction or -y direction). Specifically, the first peripheral island portions (A11) of the first peripheral area (A1) and the second peripheral island portions (A21) of the second peripheral area (A2) may be arranged symmetrically with respect to the center line (IA). The first peripheral bridge parts (A12) of the first peripheral area (A1) and the second peripheral bridge parts (A22) of the second peripheral area (A2) can be arranged symmetrically with respect to the center line (IA).

[0173] The second peripheral island portions (A21) may have a symmetrical shape with respect to the center line (IA) with respect to the first peripheral island portions (A11). The second peripheral bridge portions (A22) may have a symmetrical shape with respect to the center line (IA) with respect to the first peripheral bridge portions (A12). For example, the first peripheral bridge portions (A12) may have a shape roughly like the 'letter S', and the second peripheral bridge portions (A22) may have a shape roughly like the 'letter S' reversed left and right.

[0174] Meanwhile, as described with reference to FIG. 3A, gate driving circuits may be arranged in the first peripheral area (A1) and the second peripheral area (A2), respectively. At least some of the first peripheral island portions (A11) of the first peripheral area (A1) may include driver units of the gate driving circuit arranged on the left. The first peripheral bridge portions (A12) may include wirings electrically connected to the driver units of the adjacent first peripheral island portions (A11). In addition, at least some of the second peripheral island portions (A21) of the second peripheral area (A2) may include driver units of the gate driving circuit arranged on the right. The second peripheral bridge portion (A22) may include wirings electrically connected to the driver units of the adjacent second peripheral island portions (A21).

[0175] The gate driving circuit may include a plurality of stages for outputting gate signals, respectively. The plurality of stages may sequentially output gate signals based on a control signal. Each driver unit may include at least one stage. The driver unit may include a node control unit and a buffer transistor. The node control unit may include a plurality of transistors and capacitors, and may control a voltage of a node using a start signal, etc. provided through an input terminal. The buffer transistor may be a transistor arranged to isolate a signal source from a circuit driven by the signal source. In addition, the wires connected to the gate driving circuit may be signal lines for electrical signals and / or voltage lines for providing voltages to the gate driving circuit. The wires may correspond to, for example, a clock wire for providing a clock signal to the gate driving circuit, a gate high-voltage wire for applying a driving voltage, and a gate low-voltage wire, etc.

[0176] The driver units included in the first peripheral island portions (A11) and the driver units included in the second peripheral island portions (A21) can be arranged symmetrically with respect to the center line (IA). The wires included in the first peripheral bridge portions (A12) and the wires included in the second peripheral bridge portions (A22) can be arranged symmetrically with respect to the center line (IA).

[0177] Referring to FIG. 9, for example, the first peripheral island (A11) of part A may include a first driver unit (GDU1), and the first driver unit (GDU1) may include a node control unit (NC) and a buffer transistor (BF). The second peripheral island (A21) of part B may include a second driver unit (GDU2), and the second driver unit (GDU2) may include a node control unit (NC') and a buffer transistor (BF'). The first driver unit (GDU1) and the second driver unit (GDU2) may be symmetrically arranged with respect to the center line (IA). For example, the node control unit (NC) may be arranged on the left side, and the buffer transistor (BF) may be arranged on the right side, within the first driver unit (GDU1). Within the second driver unit (GDU2), the node control unit (NC') can be placed on the right, and the buffer transistor (BF') can be placed on the left.

[0178] In addition, the first peripheral bridge portion (A12) extended to the left of the first peripheral island portion (A11) of part A may include a first wiring (L1) electrically connected to the first driver unit (GDU1). The second peripheral bridge portion (A22) extended to the right of the second peripheral island portion (A21) of part B may include a second wiring (L2) electrically connected to the second driver unit (GDU2). The first wiring (L1) of the first peripheral bridge portion (A12) and the second wiring (L2) of the second peripheral bridge portion (A22) may be arranged symmetrically with respect to the center line (IA).

[0179] Referring to Fig. 9, the first peripheral bridge portion (A12) and the second peripheral bridge portion (A22) have a curved shape, and there may be an area (see F and G) on the inside of the curved portion where pressure (strain) may be applied and thus wiring cannot be formed. That is, the first peripheral bridge portion (A12) and the second peripheral bridge portion (A22) may have a wiring designable area (e.g., F and G). As illustrated in Fig. 9, the wiring designable area may vary depending on the curved direction of the shape of each bridge portion, etc.

[0180] In one comparative example, if the first island portions of the first peripheral region and the second island portions of the second peripheral region are not arranged symmetrically with respect to the center line, or if the first peripheral bridge portions of the first peripheral region and the second peripheral bridge portions of the second peripheral region are not arranged symmetrically with respect to the center line, the design between the driver units and wirings of the first peripheral region and the driver units and wirings of the second peripheral region may be different, and a deviation may occur in the output of the gate driving circuit of the first peripheral region and the output of the gate driving circuit of the second peripheral region.

[0181] For example, when an inversion design is performed to symmetrically arrange the driver units included in the first peripheral islands and the driver units included in the second peripheral islands, and to symmetrically arrange the wirings included in the first peripheral bridge and the wirings included in the second peripheral bridge, and the shapes of the first peripheral bridge and the second peripheral bridge are the same, the designs of the wirings of the first peripheral bridge and the wirings of the second peripheral bridge may differ depending on the constraints on the wiring design area according to the shape of the bridge. Accordingly, the designs of the driver units of the first peripheral island and the driver units of the second peripheral island may also differ. In this case, a deviation may occur in the output of the gate driving circuit of the first peripheral area and the output of the gate driving circuit of the second peripheral area due to the differential design of the driver units and wiring of the first peripheral area and the driver units and wiring of the second peripheral area.

[0182] However, according to one embodiment of the present invention, the first peripheral island portions (A11) of the first peripheral area (A1) and the second peripheral island portions (A21) of the second peripheral area (A2) are arranged symmetrically with respect to the center line (IA), and the first peripheral bridge portions (A12) of the first peripheral area (A1) and the second peripheral bridge portions (A22) of the second peripheral area (A2) can be arranged symmetrically with respect to the center line (IA). Specifically, the driver units included in the first peripheral first peripheral island portions (A11) and the driver units included in the second peripheral island portions (A21) can be arranged symmetrically with respect to the center line (IA), and the second peripheral island portions (A21) can have a symmetrical shape with respect to the center line (IA) with respect to the first peripheral island portions (A11). The wirings included in the first peripheral bridge portions (A12) and the wirings included in the second peripheral bridge portions (A22) can be arranged symmetrically with respect to the center line (IA). The second peripheral island portions (A21) can have a symmetrical shape with respect to the first peripheral island portions (A11). In this case, the driver units and wirings of the first peripheral region (A1) and the driver units and wirings of the second peripheral region (A2) can be designed to be equivalent. Therefore, the deviation between the output of the gate driving circuit of the first peripheral region (A1) and the output of the gate driving circuit of the second peripheral region (A2) can be eliminated.

[0183] Referring again to FIGS. 8A and 8B , the display device (1) may include third peripheral island portions (A31) spaced apart from each other in the third peripheral area (A3) and third peripheral bridge portions (A32) extending to adjacent third peripheral island portions (A31). The third peripheral bridge portions (A32) may be spaced apart from each other by third peripheral opening portions (A33) positioned between the third peripheral island portions (A31).

[0184] In one embodiment, as illustrated in FIG. 8B, the structure of the third peripheral region (A3) may be identical to the structure of the first peripheral region (A1). The arrangement structure of the third peripheral island portions (A31), the third peripheral bridge portions (A32), and the third peripheral opening portions (A33) of the third peripheral region (A3) may be substantially identical to the arrangement structure of the first peripheral island portions (A11), the first peripheral bridge portions (A12), and the first peripheral opening portions (A13) of the first peripheral region (A1). In addition, the third peripheral island portion (A31), the third peripheral bridge portion (A32), and the third peripheral opening portion (A33) of the third peripheral area (A3) may have substantially the same shape as the first peripheral island portion (A11), the first peripheral bridge portion (A12), and the first peripheral opening portion (A13) of the first peripheral area (A1), respectively. For example, the third peripheral bridge portion (A32) may have the same shape as the first peripheral bridge portion (A12). The third peripheral bridge portion (A32) may have a winding shape. For example, the third peripheral bridge portion (A32) may have approximately the shape of the 'letter S'.

[0185] However, the present invention is not limited thereto. In another embodiment, as illustrated in FIG. 10, the structure of the third peripheral region (A3) may be identical to the structure of the second peripheral region (A2). The arrangement structure of the third peripheral island portions (A31), the third peripheral bridge portions (A32), and the third peripheral opening portions (A33) of the third peripheral region (A3) may be substantially identical to the arrangement structure of the second peripheral island portions (A21), the second peripheral bridge portions (A22), and the second peripheral opening portions (A23) of the second peripheral region (A2). In addition, each of the third peripheral island portion (A31), the third peripheral bridge portion (A32), and the third peripheral opening portion (A33) of the third peripheral area (A3) may have substantially the same shape as each of the second peripheral island portion (A21), the second peripheral bridge portion (A22), and the second peripheral opening portion (A23) of the second peripheral area (A2). For example, the third peripheral bridge portion (A32) may have the same shape as the second peripheral bridge portion (A22). The third peripheral bridge portion (A32) may have a winding shape. For example, the third peripheral bridge portion (A32) may have a shape roughly similar to the letter 'S' reversed left and right.

[0186] At least some of the third peripheral island portions (A31) and the third peripheral bridge portions (A32) of the third peripheral area (A3) may be dummy island portions or dummy bridge portions that do not include driving circuits or wiring. Some of the third peripheral island portions (A31) and the third peripheral bridge portions (A32) may also include wiring. For example, some of the third peripheral island portions (A31) and the third peripheral bridge portions (A32) may include wiring that is connected to a gate driving circuit arranged in the first peripheral area (A1) or the second peripheral area (A2).

[0187] Bridge sections may be arranged in the intermediate area (BA). First intermediate bridge sections (B12) extending to the display area (DA) and the first peripheral area (A1) may be arranged in the first intermediate area (B1). One end of the first intermediate bridge section (B12) may extend to the first peripheral island section (A11) and / or the first peripheral bridge section (A12), and the other end of the first intermediate bridge section (B12) may extend to the main island section (D11) and / or the main bridge section (D12).

[0188] In one embodiment, the structure of the first intermediate area (B1) of FIG. 8B may be the same as the structure of the second sub-non-display area (SNDA2) described with reference to FIG. 4C. For example, the first intermediate bridge portion (B12) of the first intermediate area (B1) may correspond to the third bridge portion (23) of the second sub-non-display area (SNDA2) described with reference to FIG. 4C.

[0189] The first intermediate bridge portion (B12) may have a winding shape. In one embodiment, the shape of the first intermediate bridge portion (B12) may be different from the shape of the main bridge portion (D12) and the shape of the first peripheral bridge portion (A12). The width of the first intermediate bridge portion (B12) may be different from the width of the main bridge portion (D12) and / or the width of the first peripheral bridge portion (A12). For example, the width of the first intermediate bridge portion (B12) may be larger than the width of the main bridge portion (D12) and smaller than the width of the first peripheral bridge portion (A12). First-first intermediate openings (B13a) and first-second intermediate openings (B13b) having different shapes may be alternately arranged between the first intermediate bridge portions (B12) in the second direction (e.g., +y direction or -y direction).

[0190] In the second intermediate area (B2), second intermediate bridge portions (B22) extending to the display area (DA) and the second peripheral area (A2) may be arranged. One end of the second intermediate bridge portion (B22) may extend to the second peripheral island portion (A21) and / or the second peripheral bridge portion (A22), and the other end of the second intermediate bridge portion (B22) may extend to the main island portion (D11) and / or the main bridge portion (D12).

[0191] The second intermediate bridge portion (B22) may have a winding shape. In one embodiment, the shape of the second intermediate bridge portion (B22) may be different from the shape of the main bridge portion (D12) and the shape of the second peripheral bridge portion (A22). The width of the second intermediate bridge portion (B22) may be different from the width of the main bridge portion (D12) and / or the width of the first peripheral bridge portion (A12). For example, the width of the second intermediate bridge portion (B22) may be larger than the width of the main bridge portion (D12) and smaller than the width of the first peripheral bridge portion (A12). Second-first intermediate openings (B23a) and second-second intermediate openings (B23b) having different shapes may be alternately arranged between the second intermediate bridge portions (B22) in the second direction (e.g., the +y direction or the -y direction).

[0192] Third intermediate bridge portions (B32) extending to the display area (DA) and the third peripheral area (A3) may be arranged in the third intermediate area (B3). One end of the third intermediate bridge portion (B32) may extend to the third peripheral island portion (A31) and / or the third peripheral bridge portion (A32), and the other end of the third intermediate bridge portion (B32) may extend to the main island portion (D11) and / or the main bridge portion (D12).

[0193] The third intermediate bridge portion (B32) may have a winding shape. In one embodiment, the shape of the third intermediate bridge portion (B32) may be different from the shape of the main bridge portion (D12) and the shape of the third peripheral bridge portion (A32). The width of the third intermediate bridge portion (B32) may be different from the width of the main bridge portion (D12) and / or the width of the third peripheral bridge portion (A32). For example, the width of the third intermediate bridge portion (B32) may be larger than the width of the main bridge portion (D12) and may be the same as the width of the third peripheral bridge portion (A32). Third-first intermediate openings (B33a) and third-second intermediate openings (B33b) having different shapes may be alternately arranged between the third intermediate bridge portions (B32) in the first direction (e.g., in the +x direction or the -x direction). In the third intermediate region (B3), a third-third intermediate opening (B33c) having a different shape from the third-first intermediate opening (B33a) and the third-second intermediate opening (B33b) may be arranged at both ends in the first direction (e.g., +x direction or -x direction).

[0194] In the fourth intermediate region (B4), fourth intermediate bridge portions (B42) extending to the first peripheral region (A1) and the third peripheral region (A3) may be arranged. One end of the fourth intermediate bridge portion (B42) may extend to the first peripheral island portion (A11) and / or the first peripheral bridge portion (A12), and the other end of the fourth intermediate bridge portion (B42) may extend to the third peripheral island portion (A31) and / or the third peripheral bridge portion (A32).

[0195] The fourth intermediate bridge portion (B42) may have a winding shape. In one embodiment, as illustrated in FIG. 8B, the shape of the fourth intermediate bridge portion (B42) may be different from the shapes of the first peripheral bridge portion (A12) and the third peripheral bridge portion (A32). However, the present invention is not limited thereto.
