[0069] The display device (1) can be extended in multiple directions, such as a first direction (e.g., x direction and / or -x direction), a second direction (e.g., y direction and / or -y direction), and a third direction (e.g., z direction and / or -z direction) by an external force applied by an external object or a part of a person's body. As shown in FIG. 2f, the display area (DA) and / or non-display area (NDA) of the display device (1) can be extended in the ±x direction, ±y direction, and ±z direction.

[0070] FIG. 3a is a schematic plan view of a display device (1) according to one embodiment of the present invention. FIG. 3b is a schematic perspective view of a display device (1) according to one embodiment of the present invention.

[0071] Referring to FIGS. 3a and 3b, a display device (1) may have a substrate (100). The substrate (100) may have a display area (DA) and a non-display area (NDA) outside the display area (DA). In this case, the substrate (100) may include a first area (1A), a second area (2A), and a banding area (BA). In this case, the first area (1A) may be a display unit, and the second area (2A) may be a connection unit connected to an external device. In this case, the display unit may have the display area (DA) exposed to the outside and can display an image according to the operation of the display area (DA). The display area (DA) as described above may be included in the first area (1A), and the non-display area (NDA) may include a part of the first area (1A) excluding the display area (DA), the second area (2A), and the banding area (BA).

[0072] The first region (1A) may be non-square in shape. The non-square shape may be, for example, a circle, an ellipse, a polygon that is partly circular, or a polygon that is not a square. Of course, the first region (1A) may have the shape of a square or a square with rounded corners.

[0073] As illustrated in FIG. 3b, the display device (1) may be provided in a dome shape in the first region (1A). For example, the display device (1) may be extended in the first region (1A) in a first direction (e.g., x direction and / or -x direction), a second direction (e.g., y direction and / or -y direction), and a third direction (e.g., z direction and / or -z direction), as described with reference to FIG. 2f. Accordingly, the display area (DA) and non-display area (NDA) placed in the first region (1A) may be extended in the first direction (e.g., x direction and / or -x direction), the second direction (e.g., y direction and / or -y direction), and the third direction (e.g., z direction and / or -z direction), respectively.

[0074] The substrate (100) has a bending region (BA) extended in a first direction (e.g., x direction and / or -x direction). The bending region (BA) is located between the first region (1A) and the second region (2A) in a second direction (e.g., y direction and / or -y direction) that intersects the first direction. For example, the substrate (100) may be bent around a bending axis (BAX) extended in the first direction (e.g., x direction and / or -x direction), as shown in FIG. 3b. FIG. 3b is illustrated as having the substrate (100) bent with the same radius of curvature with respect to the bending axis (BAX), but the present invention is not limited thereto. The substrate (100) may be bent with an uneven radius of curvature with respect to the bending axis (BAX).

[0075] The substrate (100) may include various materials having flexible or bendable properties, such as polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, or polymer resins such as cellulose acetate propionate. The substrate (100) may have a single layer or a multilayer structure of the above materials, and in the case of a multilayer structure, may further include an inorganic layer.

[0076] The first area (1A) includes a display area (DA). Of course, as shown in FIG. 3a, the first area (1A) includes a portion of the non-display area (NDA) outside the display area (DA) in addition to the display area (DA). The second area (2A) includes another portion of the non-display area (NDA).

[0077] The display area (DA) may have a shape corresponding to the shape of a part of the substrate (100). In FIG. 3a, an example is illustrated in which a part of the substrate (100) is circular and the display area (DA) is circular corresponding to the shape of the part of the substrate (100).

[0078] A display area (DA) includes a plurality of pixels (PX) to realize an image. The plurality of pixels (PX) may be realized by a light-emitting element, and the light-emitting element may be driven by a pixel driving circuit connected thereto. The pixel driving circuit may include components such as a thin film transistor (TFT) and a storage capacitor. The pixel driving circuit may be connected to a scan line and a data line that intersects the scan line. Additionally, the pixel driving circuit may be connected to a driving voltage line (PL).

[0079] Each pixel (PX) emits light of, for example, red, green, blue, or white, and may include, for example, an organic light-emitting diode. A display area (DA) provides a predetermined image through the light emitted from the pixels (PX). As described above, a pixel (PX) refers to a subpixel that emits light of any one of the colors red, green, blue, or white.

[0080] The non-display area (NDA) of the first area (1A) is an area where pixels (PX) are not placed and does not provide an image. A first power supply line (30) and a second power supply line (40) that apply different power supply voltages may be placed in the non-display area (NDA). Additionally, a gate driving circuit (not shown) may be placed in the non-display area (NDA).

[0081] The first power supply line (30) may be positioned to surround at least a portion of the display area (DA) in the non-display area (NDA). The first power supply line (30) may be positioned to surround most of the display area (DA), excluding the portion where the second power supply line (40) is positioned in the non-display area (NDA). In some embodiments, the first power supply line (30) may be positioned to surround a portion of the second power supply line (40). The first power supply line (30) may be electrically connected to the opposing electrodes of the light-emitting elements positioned in the display area (DA) to transmit a common voltage. Meanwhile, the first power supply line (30) may be connected to the pad (2111) of the pad portion (20). Since the first power supply line (30) is connected to the pad (2111), it may include a portion extending to the pad portion (20), for example, a portion extending in the -y direction.

[0082] The second power supply line (40) may be positioned to correspond to the lower part of the display area (DA) in the non-display area (NDA). A plurality of driving voltage lines (PL) that transmit driving voltage to a plurality of pixel driving circuits positioned in the display area (DA) may be connected to the second power supply line (40). Meanwhile, the second power supply line (40) may be connected to the pad (2112) of the pad section (20). Since the second power supply line (40) is connected to the pad section (20), it may include a portion extended to the pad section (20), for example, a portion extended in the -y direction.

[0083] A gate driving circuit (not shown) may be placed in a portion of the display area (DA) in the non-display area (NDA). For example, the gate driving circuit may be placed on the left, right, or both sides of the display area (DA). A scan signal generated by the gate driving circuit may be provided to pixels through a scan line.

[0084] A pad portion (20) may be disposed in the second area (2A). The pad portion (20) includes a plurality of pads (2111, 2112, 2113). The pad portion (20) is exposed without being covered by an insulating layer and may be electrically connected to a control unit such as a flexible printed circuit board (FPCB) or a driving driver (150).

[0085] The driving driver (150) is placed on a separate flexible printed circuit board (FPCB), and the flexible printed circuit board (FPCB) can be connected to the pad portion (20). In another embodiment, the driving driver (150) can be placed in various ways. For example, the driving driver (150) can be placed directly on the upper surface of the substrate that extends and protrudes from the substrate (100) in a COG (Chip On Glass) or COP (Chip On Plastic) manner.

[0086] The control unit converts multiple video signals transmitted from the outside into multiple video data signals and transmits the converted signals to the display area (DA) through the pad unit (20). Additionally, the control unit receives a vertical synchronization signal, a horizontal synchronization signal, and a clock signal, generates a control signal to control the operation of a gate driving circuit (not shown), and transmits it to the gate driving circuit through the pad unit (20). The control unit can transmit different voltages to the first power supply line (30) and the second power supply line (40), respectively, through the pad unit (20). The pad unit (20) is connected to multiple fan-out wirings (60) and can transmit voltage and various signals to the display area (DA).

[0087] Multiple fan-out wires (60) may be arranged to overlap with the bending area (BA). The fan-out wires (60) may be arranged to extend from the first area (1A) through the bending area (BA) to the second area (2A). The fan-out wires (60) may be extended to intersect the bending axis (BAX). The fan-out wires (60) may be arranged in various ways, such as intersecting perpendicularly with the bending axis (BAX) or intersecting obliquely at a predetermined angle. Additionally, the fan-out wires (60) may have various shapes, such as curved shapes or zigzag shapes, rather than straight shapes.

[0088] FIG. 4a is a plan view of area A of FIG. 3a enlarged as part of a display device (1) according to one embodiment of the present invention.

[0089] Referring to FIG. 4a, the display device (1) may include first island sections (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 sections (12) connecting adjacent first island sections (11).

[0090] Each first island section (11) may be connected to a plurality of first bridge sections (12). For example, each first island section (11) may be connected to four first bridge sections (12). Two first bridge sections (12) may be positioned on both sides of the first island section (11) along a first direction (e.g., x direction or -x direction), and the remaining two first bridge sections (12) may be positioned on both sides of the first island section (11) along a second direction (e.g., y direction or -y direction). In one embodiment, four first bridge sections (12) may be connected to each of the four sides of the first island section (11). Each of the four first bridge sections (12) may be adjacent to each corner of the first island section (11).

[0091] The first bridge sections (12) may be spaced apart from each other by a first opening (CS1) located between the first bridge sections (12). In one embodiment, a first opening (CS1) approximately H-shaped and a first opening (CS1) approximately I-shaped, which is the aforementioned H-shaped rotated 90 degrees, may be alternately arranged along a first direction (e.g., x-direction or -x-direction) and a second direction (e.g., y-direction or -y-direction), respectively. Both ends of each first bridge section (12) are connected to each of the adjacent first island sections (11), and one side of each first bridge section (12) may be spaced apart from one side of the adjacent first island section (11) and / or one side of the other first bridge section (12) by the first opening (CS1).

[0092] The display device (1) may include second island sections (21) spaced apart from each other in a non-display area, for example, a first non-display area (NDA1) shown in FIG. 4a, and second bridge sections (22) connecting adjacent second island sections (21).

[0093] Each second island section (21) may extend along a first direction (e.g., x direction or -x direction). The second island sections (21) may be spaced apart from each other along a second direction (e.g., y direction or -y direction) that intersects the first direction (e.g., x direction or -x direction). Each second island section (21) may include drivers of a gate driving circuit.

[0094] The second bridge section (22) may have a serpentine shape. The length of the second bridge section (22) may be greater than the shortest distance between adjacent second island sections (21) along the second direction (e.g., the y direction or the -y direction). In one embodiment, the second bridge section (22) may have a shape of approximately omega (Ω) that is convex toward the first direction (e.g., the x direction or the -x direction). The second bridge sections (22) may be positioned between adjacent second island sections (21) but spaced apart from each other.

[0095] The second bridge sections (22) between adjacent second island sections (21) may be spaced apart from each other by a second opening (CS2). Between adjacent second island sections (21), the second openings (CS2) and the second bridge sections (22) may be arranged alternately along a first direction (e.g., x direction or -x direction). The second openings (CS2) may have the same shape as each other. Both ends of each second bridge section (22) are connected to adjacent second island sections (21), but one side of each second bridge section (22) may be spaced apart from the side of the adjacent second island section (21) and / or the side of the other second bridge section (22) by the second opening (CS2).

[0096] Any one second island section (21) placed in the first non-display area (NDA1) may correspond to a plurality of first island sections (11) arranged in the display area (DA). For example, any one second island section (21) placed in the first non-display area (NDA1) may correspond to the first island sections (11) arranged in the (i)th row and the first island sections (11) arranged in the (i+1)th row in the display area (DA) (where i is a positive number greater than 0). FIG. 4a illustrates that one second island section (21) corresponds to two rows of first island sections (11), but the present invention is not limited thereto. In another embodiment, any one second island section (21) placed in the first non-display area (NDA1) may correspond to n rows of first island sections (11) placed in the display area (DA) (where n is a positive number greater than or equal to 3).

[0097] A non-display area, such as a first non-display area (NDA1), may include a first sub-non-display area (SNDA1) in which the aforementioned second island sections (21) and second bridge sections (22) are arranged, and a second sub-non-display area (SNDA2) between the first sub-non-display area (SNDA1) and the display area (DA). In the second sub-non-display area (SNDA2), third bridge sections (23) for connecting the display area (DA) and the first sub-non-display area (SNDA1) may be arranged. One end of the third bridge section (23) may be connected to the second island section (21) and / or the second bridge section (22), and the other end of the third bridge section (23) may be connected to the first island section (11) and / or the first bridge section (12).

[0098] The third bridge section (23) may have a wavy shape. In one embodiment, the shape of the third bridge section (23) may differ from the shapes of the first bridge section (12) and the second bridge section (22), respectively. In one embodiment, as shown in FIG. 4a, the third bridge section (23) may have a shape of approximately omega (Ω) that is convex toward the second direction (e.g., the y direction or the -y direction). Adjacent third bridge sections (23) arranged along the second direction (e.g., the y direction or the -y direction) may have a structure that is symmetrical to each other, such that one of them is convex toward the y direction and the other is convex toward the -y direction. Between the third bridge sections (23), there may be a structure in which a third opening (CS3) and a fourth opening (CS4) of different shapes are repeated. The width of the third bridge section (23) may differ from the width of the first bridge section (12) and the width of the second bridge section (22). In one embodiment, the width of the third bridge section (23) may be greater than the width of the first bridge section (12) and smaller than the width of the second bridge section (22).

[0099] FIG. 4a shows that the second island portion (21) and the second bridge portion (22) of the non-display area, for example, the first non-display area (NDA1), each have different shapes from the first island portion (11) and the first bridge portion (12) of the display area (DA). In another embodiment of the present invention, the second island portion (21) and the second bridge portion (22) of the non-display area may each have the same shape as the first island portion (11) and the first bridge portion (12) of the display area (DA).

[0100] FIG. 4b is a plan view of the enlarged area A of FIG. 3a as part of a display device (1) according to one embodiment of the present invention.

[0101] Referring to FIG. 4b, the display device (1) includes first island sections (11) spaced apart from each other in the display area (DA) and first bridge sections (12) that are spaced apart from each other by a first opening (CS1) and connect adjacent first island sections (11). The structure of the display area (DA) in FIG. 4b may be the same as the structure of the display area (DA) described above with reference to FIG. 4a.

[0102] The display device (1) may include second island sections (21) and second bridge sections (22) disposed in a non-display area, for example, a first non-display area (NDA1). In one embodiment, the second island sections (21) and the second bridge sections (22) may each have substantially the same shape as the first island sections (11) and the first bridge sections (12).

[0103] The second island sections (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) in a non-display area, e.g., a first non-display area (NDA1). Each of the second bridge sections (22) may connect adjacent second island sections (21). The second bridge sections (22) may be spaced apart from each other by a second opening (CS2) located between the second bridge sections (22).

[0104] The second opening (CS2) may have substantially the same shape as the first opening (CS1). For example, a second opening (CS2) with an approximate H shape and a second opening (CS2) with an approximate I shape may be alternately arranged in a non-display area, such as a first non-display area (NDA1). Both ends of each second bridge section (22) are connected to each of the adjacent second island sections (21), and one side of each second bridge section (2) may be separated from one side of the adjacent second island section (21) and / or one side of the other second bridge section (22) by the second opening (CS2).

[0105] Each second island section (21) can be connected to four second bridge sections (22). Each second island section (21) may include drivers of gate driving circuits.

[0106] Any row of the second island portions (21) placed in the first non-display area (NDA1) may correspond to any row of the first island portions (11) arranged in the display area (DA). For example, the second island portions (21) arranged in the (i)th row along the first direction (e.g., x direction or -x direction) in the first non-display area (NDA1) may correspond to the first island portions (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).

[0107] The display device (1) may include third bridge sections (23) disposed in a second sub-non-display area (SNDA2) to connect a display area (DA) and a first sub-non-display area (SNDA1). A non-display area, such as a first non-display area (NDA1), may include a first sub-non-display area (SNDA1) in which second island sections (21) and second bridge sections (22) are disposed, and a second sub-non-display area (SNDA2) located between the first sub-non-display area (SNDA1) and the display area (DA), which includes the third bridge sections (23). The third bridge section (23) may be substantially identical to the first bridge section (12) and the second bridge section (22). For example, the width of the third bridge section (23) may be the same as the width of the first bridge section (12) and the width of the second bridge section (22).

[0108] FIG. 4c is a plan view of area A of FIG. 3a enlarged as part of a display device according to one embodiment of the present invention.

[0109] Referring to FIG. 4c, the display device (1) may include first island sections (11) that are 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 a display area (DA), and first bridge sections (12) that connect adjacent first island sections (11).

[0110] The first bridge sections (12) may be spaced apart from each other by a first opening (CS1) located between the first bridge sections (12). The first bridge section (12) may have a wavy shape. For example, as shown in FIG. 4c, the first bridge section (12) may have a shape of approximately the letter 'S', such as including two round sections (12R) and a straight section (12S) between the two round sections (12R).

[0111] Each first island section (11) may be connected to a plurality of first bridge sections (12). For example, each first island section (11) may be connected to four first bridge sections (12). Two first bridge sections (12) may be placed on both sides of the first island section (11) along a first direction (e.g., x direction or -x direction), and the remaining two first bridge sections (12) may be placed on both sides of the first island section (11) along a second direction (e.g., y direction or -y direction). Four first bridge sections (12) may each be connected to four sides of the first island section (11). Each of the four first bridge sections (12) may be adjacent to each corner of the first island section (11).

[0112] The display device (1) may include second island sections (21) that are 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 a non-display area, e.g., a first non-display area (NDA1) shown in FIG. 4c, and second bridge sections (22) that connect adjacent second island sections (21).

[0113] The second bridge sections (22) may be spaced apart from each other by a second opening (CS2) located between the second bridge sections (22). The second bridge section (22) may have a wavy shape. For example, as shown in FIG. 4c, the second bridge section (22) may have a shape of approximately the letter 'S'. The size and / or width of the second bridge section (22) may differ from the size and / or width of the first bridge section (12). For example, the size and / or width of the second bridge section (22) may be larger than the size and / or width of the first bridge section (12). The radius of curvature of the rounded portion of the second bridge section (22) may differ from the radius of curvature of the rounded portion of the first bridge section (12). For example, the radius of curvature of the rounded portion of the second bridge section (22) may be larger than the radius of curvature of the rounded portion of the first bridge section (12).

[0114] Each second island section (21) may be connected to a plurality of second bridge sections (22). Each second island section (21) may be connected to four second bridge sections (22). Two second bridge sections (22) may be positioned on both sides of the second island section (21) along a first direction (e.g., x direction or -x direction), and the remaining two second bridge sections (22) may be positioned on both sides of the second island section (21) along a second direction (e.g., y direction or -y direction). In one embodiment, four second bridge sections (22) may be connected to each of the four sides of the second island section (21). Each second bridge section (22) may be connected to the central part of each side of the second island section (21).

[0115] Any row of second island sections (21) placed in the first non-display area (NDA1) may correspond to multiple rows of first island sections (11) arranged in the display area (DA). For example, any row of second island sections (21) placed in the first non-display area (NDA1) may correspond to the first island sections (11) arranged in the (i)th row and the first island sections (11) arranged in the (i+1)th row of the display area (DA) (where i is a positive number greater than 0). In another embodiment, any row of second island sections (21) may correspond to n rows of first island sections (11) (where n is a positive number greater than or equal to 3).

[0116] A non-display area, such as a first non-display area (NDA1), may include a first sub-non-display area (SNDA1) in which the aforementioned second island sections (21) and second bridge sections (22) are arranged, and a second sub-non-display area (SNDA2) between the first sub-non-display area (SNDA1) and the display area (DA). In the second sub-non-display area (SNDA2), third bridge sections (23) may be arranged to connect the display area (DA) and the first sub-non-display area (SNDA1). One end of the third bridge section (23) may be connected to the second island section (21), and the other end of the third bridge section (23) may be connected to the first island section (11). For example, one end of the third bridge section (23) can be connected to the central part of one side of the second island section (21), and the other end of the third bridge section (23) can be connected to the central part of one side of the first island section (11).

[0117] The third bridge section (23) may have a wavy shape. In one embodiment, the shape of the third bridge section (23) may differ from the shape of the first bridge section (12) and the second bridge section (22), respectively. The width of the third bridge section (23) may differ from the width of the first bridge section (12) and the width of the second bridge section (22). The width of the third bridge section (23) may be greater than the width of the first bridge section (12) and smaller than the width of the second bridge section (22). In the second direction (e.g., the y direction or the -y direction), a third opening (CS3) and a fourth opening (CS4) of different shapes may be alternately arranged between the third bridge sections (23).

[0118] FIGS. 5a to 5h are plan views of an enlarged area A of FIG. 3a as part of a display device (1) according to one embodiment of the present invention.

[0119] Referring to FIGS. 5a through 5h, the display device (1) may include first island sections (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 sections (12) connecting adjacent first island sections (11).

[0120] Each first island section (11) may be connected to a plurality of first bridge sections (12). For example, each first island section (11) may be connected to four first bridge sections (12). Two first bridge sections (12) may be positioned on both sides of the first island section (11) along a first direction (e.g., x direction or -x direction), and the remaining two first bridge sections (12) may be positioned on both sides of the first island section (11) along a second direction (e.g., y direction or -y direction). In one embodiment, four first bridge sections (12) may be connected to each of the four sides of the first island section (11). Each of the four first bridge sections (12) may be adjacent to each corner of the first island section (11).

[0121] The first bridge sections (12) may be spaced apart from each other by a first opening (CS1) located between the first bridge sections (12). In one embodiment, a first opening (CS1) extending in the first direction and a first opening (CS1) extending in the second direction may be alternately arranged along a first direction (e.g., x direction or -x direction) and a second direction (e.g., y direction or -y direction), respectively.

[0122] A non-display area, for example, a first non-display area (NDA1), may include a first sub-non-display area (SNDA1) and a second sub-non-display area (SNDA2) between the first sub-non-display area (SNDA1) and a display area (DA). The second sub-non-display area (SNDA2) may connect the display area (DA) and the first sub-non-display area (SNDA1).

[0123] The display device (1) may include second island sections (21) and second bridge sections (22) disposed in a first sub-non-display area (SNDA1). In one embodiment, the second island sections (21) and the second bridge sections (22) may each have substantially the same shape as the first island sections (11) and the first bridge sections (12).

[0124] The second island sections (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) in a non-display area, e.g., a first non-display area (NDA1). Each of the second bridge sections (22) may connect adjacent second island sections (21). The second bridge sections (22) may be spaced apart from each other by a second opening (CS2) located between the second bridge sections (22).

[0125] The second opening (CS2) may have substantially the same shape as the first opening (CS1). For example, in a non-display area, such as the first non-display area (NDA1), the second opening (CS2) extended in the first direction (e.g., x direction or -x direction) and the second opening (CS2) extended in the second direction (e.g., y direction or -y direction) may be alternately arranged.

[0126] Each second island section (21) can be connected to four second bridge sections (22). Each second island section (21) may include drivers of the gate driving circuit described with reference to FIG. 3a.

[0127] The display device (1) may include third island sections (31) and third bridge sections (32) disposed in a second sub-non-display area (SNDA2). In one embodiment, the third island sections (31) and the third bridge sections (32) may each have substantially the same shape as the first island sections (11) and the first bridge sections (12). Additionally, the third island sections (31) and the third bridge sections (32) may each have substantially the same shape as the second island sections (21) and the second bridge sections (22).

[0128] The third island sections (31) 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) in a non-display area, e.g., a second non-display area (NDA2). Each of the third bridge sections (32) may connect adjacent third island sections (31). The third bridge sections (32) may be spaced apart from each other by a third opening (CS3) located between the third bridge sections (32).

[0129] The third opening (CS3) may have substantially the same shape as the first opening (CS1). Additionally, the third opening (CS3) may have substantially the same shape as the second opening (CS2). For example, in a non-display area, such as a second non-display area (NDA2), the third opening (CS3) extended in the first direction (e.g., x direction or -x direction) and the third opening (CS3) extended in the second direction (e.g., y direction or -y direction) may be alternately arranged.

[0130] Any row of second island sections (21) placed in the first sub-non-display area (SNDA1) may correspond to a plurality of rows of first island sections (11) arranged in the display area (DA). For example, any row of second island sections (21) placed in the first sub-non-display area (SNDA1) may correspond to the first island sections (11) arranged in the (i)th row of the display area (DA) and the first island sections (11) arranged in the (i+1)th row (where i is a positive number greater than 0). In another embodiment, any row of second island sections (21) may correspond to n rows of first island sections (11) (where n is a positive number greater than or equal to 3). In such a structure, the size of the second island sections (21) may be larger than the size of the first island sections (11). In addition, the size of the second bridge sections (22) may be larger than the size of the first bridge sections (12).

[0131] The third island sections (31) placed in the second sub-non-display area (SNDA2) may differ in size from one another. The size of the third island sections (31) placed adjacent to the first sub-non-display area (SNDA1) may be the same as the size of the second island sections (21). For example, the third island sections (31) of any row placed adjacent to the first sub-non-display area (SNDA1) may correspond to the first island sections (11) arranged in the (i)th row of the display area (DA) and the first island sections (11) arranged in the (i+1)th row (where i is a positive number greater than 0).

[0132] The size of the third island portions (31) positioned adjacent to the display area (DA) may be the same as the size of the first island portions (11). For example, the third island portions (31) of any row positioned adjacent to the display area (DA) may correspond to the first island portions (11) of any row positioned in the display area (DA) (where i is a positive number greater than 0). The second sub-non-display area (SNDA2) may function as a buffer area that reduces the phenomenon of strain concentration at the boundary between the display area (DA) and the first sub-non-display area (SNDA1) during the process of the display device expanding.

[0133] The shapes of the third island sections (31), third bridge sections (32), and third openings (CS3) placed in the second sub-non-display area (SNDA2) may vary according to the required design specifications as illustrated in FIGS. 5a through 5h. For example, as illustrated in FIGS. 5a, 5b, and 5e, the width and length of the third openings (CS3) in the second sub-non-display area (SNDA2) may vary. For example, as illustrated in FIG. 5c, the third openings (CS3) may be omitted in some areas of the second sub-non-display area (SNDA2). For example, as illustrated in FIG. 5d, 5f, 5g, and 5h, the shape of at least one of the third openings (CS3) placed in the second sub-non-display area (SNDA2) may vary, such as circular and T-shaped. The detailed arrangement and shape of the third island sections (31), third bridge sections (32), and third opening sections (CS3) placed in the second sub-non-display area (SNDA2) will be described later with reference to FIGS. 9a and 9b.

[0134] FIG. 6 is a cross-sectional view schematically showing a first island part (11) and a first bridge part (12) arranged in a display area (DA) of a display device (1) according to one embodiment of the present invention.

[0135] Referring to FIG. 6, the first island section (11) and the first bridge section (12) placed in the display area (DA) may be spaced apart with the first opening (CS1) in between. The first island section (11) includes light-emitting elements (LEDs) and a circuit for driving the light-emitting elements electrically connected thereto, such as a pixel driving circuit section (PC), and the first bridge section (12) may include wiring (WL) electrically connected to the pixel driving circuit sections (PCs) placed in each of the adjacent first island sections (11).

[0136] Looking at the first island portion (11), a buffer layer (1111) containing an inorganic insulating material is disposed on the substrate (100), and a pixel driving circuit portion (PC) may be disposed on the buffer layer (1111). An insulating layer (IL) containing an inorganic insulating material and / or an organic insulating material may be disposed between the pixel driving circuit portion (PC) and the light-emitting element (LED). The light-emitting element (LED) is disposed on the insulating layer (IL) and may be electrically connected to the corresponding pixel driving circuit portion (PC). The light-emitting elements (LEDs) may emit light of different colors or light of the same color. In one embodiment, the light-emitting elements (LEDs) may each emit red, green, and blue light. In some embodiments, the light-emitting elements (LEDs) may emit white light. In another embodiment, the light-emitting elements (LEDs) may each emit red, green, blue, and white light.

[0137] The substrate (100) may include a polymer resin such as polyethersulfone, polyarylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyimide, polycarbonate, cellulose triacetate, and cellulose acetate propionate. In one embodiment, the substrate (100) may be a single layer comprising the aforementioned polymer resin. In another embodiment, the substrate (100) may be a multilayer structure comprising a base layer comprising the aforementioned polymer resin and a barrier layer comprising an inorganic insulating material. The substrate (100) comprising the polymer resin may have flexible, rollable, and bendable properties.

[0138] In one embodiment, FIG. 6 illustrates three pixel driving circuit units (PCs) arranged in each first island unit (11) and three light-emitting elements (LEDs) connected to each pixel driving circuit unit (PC), but the present invention is not limited thereto. In another embodiment, the number of pixel driving circuit units (PCs) and light-emitting elements (LEDs) arranged in the first island unit (11) may be one, two, or four or more.

[0139] The encapsulation layer (300) may be placed on a light-emitting element (LED) and may protect the light-emitting element (LED) from external forces and / or moisture penetration. The encapsulation layer (300) may include an inorganic encapsulation layer and / or an organic encapsulation layer. In some embodiments, the encapsulation layer (300) may include a structure in which an inorganic encapsulation layer containing an inorganic insulating material, an organic encapsulation layer containing an organic insulating material, and an inorganic encapsulation layer containing an inorganic insulating material are laminated. In other embodiments, the encapsulation layer (300) may include an organic material such as resin. In some embodiments, the encapsulation layer (300) may include urethane epoxy acrylate. The encapsulation layer (300) may include a photosensitive material, such as a photoresist.

[0140] Looking at the first bridge section (12), an insulating layer (IL) containing an organic insulating material may be disposed on the substrate (100). When the display device (1) is stretched, the first bridge section (12), which undergoes relatively more deformation, may not have a layer containing an inorganic insulating material that is prone to cracking, unlike the first island section (11).

[0141] In one embodiment, the substrate (100) corresponding to the first bridge portion (12) may have the same stacked structure as the substrate (100) corresponding to the first island portion (11). In one embodiment, the substrate (100) corresponding to the first bridge portion (12) and the substrate (100) corresponding to the first island portion (11) may be polymer resin layers formed together in the same process. In another embodiment, the substrate (100) corresponding to the first bridge portion (12) may have a different stacked structure than the substrate (100) corresponding to the first island portion (11). In some embodiments, the substrate (100) corresponding to the first bridge portion (12) has a multilayer structure including a base layer containing a polymer resin and a barrier layer containing an inorganic insulating material, and the substrate (100) corresponding to the first bridge portion (12) may have a structure of a polymer resin layer without a layer containing an inorganic insulating material.

[0234] FIGS. 10a to 10h are plan views of an enlarged area A of FIG. 3a as part of a display device (1) according to one embodiment of the present invention.

[0235] FIG. 10a is a drawing showing the extended state of the display device (1) described with reference to FIG. 5a, FIG. 10b is a drawing showing the extended state of the display device (1) described with reference to FIG. 5b, FIG. 10c is a drawing showing the extended state of the display device (1) described with reference to FIG. 5c, FIG. 10d is a drawing showing the extended state of the display device (1) described with reference to FIG. 5d, FIG. 10e is a drawing showing the extended state of the display device (1) described with reference to FIG. 5e, FIG. 10f is a drawing showing the extended state of the display device (1) described with reference to FIG. 5f, FIG. 10g is a drawing showing the extended state of the display device (1) described with reference to FIG. 5g, and FIG. 10h is a drawing showing the extended state of the display device (1) described with reference to FIG. 5h.

[0236] Specifically, FIGS. 10a to 10h are drawings illustrating a state in which a display device (1), described with reference to FIGS. 5a to 5h, is stretched to have a strain of 1.5% along a first direction (e.g., x direction and / or -x direction) and a second direction (e.g., y direction and / or -y direction).

[0237] In FIGS. 10a to 10h, local strain values ​​according to the display area (DA), the first sub-undisplay area (NDA1), and the second sub-undisplay area (NDA2) were analyzed using computer simulation and then shown in shaded form.

[0238] In this specification, the term "elongation rate" refers to a numerical value representing the change in length (△L / L) by which the display device (1) can be extended without physical damage to the display device (1) when an external force is applied to the display device (1).
