[0050] In the following embodiments, terms such as first, second, etc. are used not in a limiting sense, but for the purpose of distinguishing one component from another component.

[0051] In the following examples, singular expressions include plural expressions unless the context clearly indicates otherwise.

[0052] In the following embodiments, terms such as "include" or "have" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added.

[0053] In the following embodiments, when a part such as a film, region, or component is described as being on or above another part, it includes not only cases where it is directly on top of another part, but also cases where another film, region, or component is interposed in between.

[0054] In the drawings, the size of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, so the present invention is not necessarily limited to what is illustrated.

[0055] In the following embodiments, the x-axis, y-axis, and z-axis are not limited to three axes in an orthogonal coordinate system and can be interpreted in a broader sense that includes them. For example, the x-axis, y-axis, and z-axis may be orthogonal to each other, but they may also refer to different directions that are not orthogonal to each other.

[0056] Where an embodiment can be implemented differently, a specific process sequence may be performed differently from the order described. For example, two processes described consecutively may be performed substantially simultaneously or proceed in the reverse order of the description.

[0057] In this specification, "on a plane" means a plane viewed from a direction perpendicular to the substrate (100, see FIG. 5). That is, "A and B spaced apart from each other on a plane" means "A and B spaced apart from each other when viewed from a direction perpendicular to the substrate (100, see FIG. 5)."

[0058] In this specification, "on a cross-section" means a plane cut in a direction perpendicular to the substrate (100, see FIG. 5). That is, "A and B spaced apart from each other on a cross-section" means "A and B spaced apart from each other on a plane cut in a direction perpendicular to the substrate (100, see FIG. 5)."

[0059] FIG. 1 is a schematic perspective view of a display device (1) according to an embodiment of the present invention. FIG. 2a and FIG. 2b are perspective views showing the display device (1) of FIG. 1 extended in a first direction. FIG. 2c is a perspective view showing the display device (1) of FIG. 1 extended in a second direction. FIG. 2d is a perspective view showing the display device (1) of FIG. 1 extended in the first direction and the second direction. FIG. 2e is a perspective view showing the display device (1) of FIG. 1 extended in a third direction.

[0060] Referring to FIG. 1, a display device (1) may include a display area (DA) and a non-display area (NDA). The display area (DA) may include a plurality of pixels. The display device (1) may provide a predetermined image using light emitted from a plurality of pixels. The non-display area (NDA) may be placed outside the display area (DA). The non-display area (NDA) is an area where pixels are not placed, and may surround the display area (DA) entirely or partially.

[0061] The display device (1) can be extended or shortened in various directions. The display device (1) can be extended in a first direction (e.g., x direction and / or -x direction) by an external force applied by an external object or a user. In one embodiment, as shown in FIGS. 2a and 2b, the display area (DA) and / or non-display area (NDA) of the display device (1) can be extended in a first direction (e.g., x direction and / or -x direction).

[0062] The display device (1) can be extended 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 shown in FIG. 2c, the display area (DA) and / or non-display area (NDA) of the display device (1) can be extended in the y direction and the -y direction. In another embodiment, one side of the display device (1) can be extended in the y direction or the -y direction while remaining fixed.

[0063] The display device (1) can be extended in multiple directions, such as a first direction (e.g., x direction and / or -x direction) and a second direction (e.g., y direction and / or -y direction), by an external force applied by an external object or a part of a person's body. As shown in FIG. 2d, the display area (DA) and / or non-display area (NDA) of the display device (1) can be extended in the ±x direction and ±y direction.

[0064] The display device (1) can be extended in a third direction (e.g., z direction or -z direction) by an external force applied by an external object or a part of a person's body. In one embodiment, FIG. 2e illustrates a part of the display device (1), such as a part of the display area (DA), protruding in the z direction. In another embodiment, a part of the display device (1), such as a part of the display area (DA), may protrude along the -z direction (or be sunken along the z direction).

[0065] FIGS. 2a to 2e illustrate a display device (1) extended in a first direction, a second direction, and / or a third direction, but the present invention is not limited thereto. In other embodiments, the display device (1) may be varied into an irregular shape, such as having two or more axes, being bent or twisted.

[0066] FIG. 3a is a schematic plan view of a display device (1) according to one embodiment of the present invention.

[0067] A plurality of pixels may be arranged in the display area (DA) of the display device (1). Each pixel may include subpixels that emit light of different colors. A light-emitting element corresponding to each subpixel may be placed in the display area (DA). A circuit for providing electrical signals to the light-emitting elements placed in the display area (DA) and to the transistors electrically connected to the light-emitting elements may be located in the non-display area (NDA) surrounding the display area (DA). A gate driving circuit (GDC) may be placed in the first non-display area (NDA1) and the second non-display area (NDA2), respectively, which are placed on both sides of the display area (DA). The gate driving circuit (GDC) may include drivers for providing electrical signals to the gate electrodes of each of the transistors electrically connected to the light-emitting elements. FIG. 3a illustrates the gate driving circuit (GDC) being placed in the first non-display area (NDA1) and the second non-display area (NDA2), respectively, but the present invention is not limited thereto. In another embodiment, the gate driving circuit (GDC) may be placed in either the first non-display area (NDA1) or the second non-display area (NDA2).

[0068] The data driving circuit (DDC) may be placed in a third non-display area (NDA3) and / or a fourth non-display area (NDA4) connecting the first non-display area (NDA1) and the second non-display area (NDA2). In one embodiment, FIG. 3a illustrates the data driving circuit (DDC) being placed in the fourth non-display area (NDA4). In another embodiment, the data driving circuit (DDC) may be placed in each of the third non-display area (NDA3) and the fourth non-display area (NDA4).

[0069] FIG. 3a illustrates a data driving circuit (DDC) placed in the fourth non-display area (NDA4) of a display device (1), but the present invention is not limited thereto. In another embodiment, the display device (1) may further include a flexible circuit board (not shown) electrically connected through a terminal portion (not shown) placed in the fourth non-display area (NDA4), and a data driving circuit (DDC) may be placed on the aforementioned flexible circuit board.

[0070] In some embodiments, the elongation of the non-display area (NDA) may be equal to or less than the elongation of the display area (DA). In one embodiment, the elongation of the non-display area (NDA) may differ from area to area. For example, the first non-display area (NDA1), the second non-display area (NDA2), and the third non-display area (NDA3) may have substantially the same elongation, but the elongation of the fourth non-display area (NDA4) may be less than the elongation of each of the first non-display area (NDA1), the second non-display area (NDA2), and the third non-display area (NDA3). In this specification, elongation refers to a numerical value representing the change in length (ΔL / 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). Here, ΔL is the amount of change in length of the display device and L represents the initial length of the display device.

[0071] FIG. 3b is a schematic plan view of a display device (1) according to one embodiment of the present invention.

[0072] Referring to FIG. 3b, the display device (1) may be defined with a flexible area (FA) and a hard area (HA). The flexible area (FA) may refer to a flexible area with a relatively high elongation rate in the display device (1), and the hard area (HA) may refer to a rigid area with a relatively low elongation rate in the display device (1).

[0073] The flexible region (FA) may be a flexible region that can be easily bent, folded, or stretched. The flexible region (FA) may be easily stretched or contracted compared to the hard region (HA). In one embodiment, a plurality of openings (not shown) may be defined in the flexible region (FA). The openings may penetrate the display device (1). The openings may be regions where components of the display device (1) are not placed. For example, a substrate included in the display device (1) may include an opening in the flexible region (FA) that has the same shape as the openings. Accordingly, the display device (1) can be easily stretched and / or contracted in various directions.

[0074] The hard region (HA) may be a rigid region that is not easily bent. In one embodiment, the hard region (HA) may be a region where no opening (not shown) penetrating the display device (1) is placed. For example, a substrate included in the display device (1) may have an area corresponding to the hard region (HA) in the hard region (HA). Accordingly, the hard region may be a region that is not easily stretched and / or contracted.

[0075] The flexible area (FA) may include at least a portion of the display area (DA) and the non-display area (NDA, FIG. 3a) surrounding the display area (DA). The hard area (HA) may include a portion of the non-display area (NDA). For example, the flexible area (FA) may include a portion of the display area (DA), the first to third non-display areas (NDA1, NDA2, NDA3), and the fourth non-display area (NDA4). The hard area (HA) may include a portion of the fourth non-display area (NDA4).

[0076] The flexible area (FA) may include a display area (DA) and a first peripheral area (A1), a second peripheral area (A2), a third peripheral area (A3), and a fourth peripheral area (A4) surrounding the display area (DA). For example, the first peripheral area (A1) may be positioned to the left (e.g., -x direction) of the display area (DA), and the second peripheral area (A2) may be positioned to the right (e.g., x direction) of the display area (DA). The third peripheral area (A3) may be positioned above (e.g., y direction) the display area (DA) and may be positioned between the first peripheral area (A1) and the second peripheral area (A2). The fourth peripheral area (A4) may be positioned below (e.g., -y direction) the display area (DA) and may be positioned between the first peripheral area (A1) and the second peripheral area (A2).

[0077] In one embodiment, 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, FIG. 3a) may be disposed in each.

[0078] In one embodiment, a data driving circuit (DDC) may be disposed in the hard area (HA). In another embodiment, a flexible circuit board (not shown) electrically connected through a terminal portion (not shown) disposed in the hard area (HA) may be further included, and a data driving circuit (DDC) may be disposed on the aforementioned flexible circuit board.

[0079] In one embodiment, a fan-out line (FWL) may be placed in the hard area (HA). The fan-out line (FWL) may extend in a direction toward the display area (DA) from the data driving circuit (DDC). Multiple fan-out lines (FWL) may be provided. In one embodiment, the fan-out line (FWL) may be a signal line. The fan-out line (FWL) may be electrically connected to a data line (DL, FIG. 6a). The length of the fan-out line (FWL) may be formed differently depending on the arrangement position. For example, the fan-out line (FWL) may extend toward a point in the display area (DA) at a greater distance from the data driving circuit (DDC) as it is arranged further from the center of the data driving circuit (DDC).

[0080] FIG. 4a is a plan view of part IV of FIG. 3a as a part of a display device (1) according to one embodiment of the present invention.

[0081] 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).

[0082] 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 of the four 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 of the four 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, the 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).

[0083] 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).

[0084] 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) to each other.

[0085] 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 the gate driving circuit (GDC, FIG. 2) described with reference to FIG. 3a.

[0086] 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.

[0087] 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).

[0088] 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).

[0089] 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).

[0090] 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).

[0091] 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).

[0092] FIG. 4b is a plan view of part IV of FIG. 3a as a part of a display device (1) according to one embodiment of the present invention.

[0093] 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.

[0094] 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).

[0095] 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).

[0096] 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).

[0097] 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 (GDC, FIG. 2) described with reference to FIG. 3a.

[0098] 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).

[0099] 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).

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

[0101] 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) to each other.

[0102] 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).

[0103] 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 of the four 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 of the four 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). The 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).

[0104] 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).

[0105] 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).

[0106] 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).

[0107] 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).

[0108] 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).

[0109] 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).

[0110] FIG. 4d is a plan view of the display area (DA) of FIG. 3a enlarged as part of a display device (1) according to one embodiment of the present invention.

[0111] Referring to FIG. 4d, the display device (1) may include first island sections (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 a display area (DA), and first bridge sections (12) connecting adjacent first island sections (11). The first bridge sections (12) may be spaced apart from each other by a first opening (CS1) located between the first bridge sections (12).

[0112] In one embodiment, at least one of the sides of the first island portion (11) may be oblique to a virtual line connecting the center (C) of the first island portions (11) along a first direction (e.g., x direction or -x direction) and / or a second direction (e.g., y direction or -y direction). In this regard, FIG. 4d illustrates that the first island portion (11) comprises first to fourth sides (11a, 11b, 11c, 11d), each of which extends along a direction oblique to a first virtual line (IM1) connecting the center (C) of the first island portions (11). FIG. 4d illustrates that the first virtual line (IM1) is extended in a first direction (e.g., x direction or -x direction), but the first virtual line (IM1) may be extended along a second direction (e.g., y direction or -y direction).

[0113] In one embodiment, the first side (11a) and the third side (11c), which are parallel to each other, may intersect the first imaginary line (IM1). The smaller angle (hereinafter referred to as the angle, T) formed by the first side (11a) and the first imaginary line (IM1) may be greater than 0 degrees and less than 90 degrees. The angle (T) formed by the third side (11c) and the first imaginary line (IM1) may be greater than 0 degrees and less than 90 degrees.

[0114] The first island section (11) can be connected to a plurality of first bridge sections (12). For example, the first island section (11) can 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).

[0115] The first bridge section (12) may have a wavy shape. For example, as shown in FIG. 4d, the first bridge section (12) may have a shape roughly like the letter 'S', such as including two round sections (12R) and a straight section (12S) between the two round sections (12R).

[0116] In one embodiment, the straight section (12S) may be substantially parallel to the sides of the adjacent first island section (11) as illustrated in FIG. 4d. For example, the straight section (12S) of each first bridge section (12) located on both sides of the first island section (11) along the first direction (e.g., x direction or -x direction) may be substantially parallel to the sides of the first island section (11) (e.g., first side (11a) and third side (11c)). The straight section (12S) of each first bridge section (12) located on both sides of the first island section (11) along the second direction (e.g., y direction or -y direction) may be substantially parallel to the sides of the first island section (11) (e.g., second side (11b) and fourth side (11d)).

[0117] Each of the first island sections (11) illustrated in FIG. 4d can be understood as having rotated each of the first island sections (11) illustrated in FIG. 4c by a first angle (e.g., acute angle) with respect to the center (C). Accordingly, at least one of the sides of the first island section (11) may be oblique to a virtual line connecting the centers (C) of the first island sections (11) along a first direction (e.g., x direction or -x direction) and / or a second direction (e.g., y direction or -y direction). Depending on the arrangement of the first island sections (11) and / or the structure of the first bridge section (12) described above, the area of ​​the first opening (CS1) illustrated in FIG. 4d may be relatively smaller than the area of ​​the first opening (CS1) illustrated in FIG. 4c, and thus the display device (1) according to the embodiment illustrated in FIG. 4d can provide a relatively high-resolution image.

[0118] FIG. 4d illustrates that the straight section (12S) of the first bridge section (12) is substantially parallel to the side of the first island section (11) adjacent to the straight section (12S), but the present invention is not limited thereto. In another embodiment, the straight section (12S) of the first bridge section (12) may be oblique to the side of the first island section (11) adjacent to the straight section (12S), as shown in FIG. 4c.

[0119] In one embodiment, the structure of the first non-display area (NDA1, FIG. 3A) of the display device (1) not disclosed in FIG. 4d may be identical to the structure of the display area (DA) disclosed in FIG. 4d. In one embodiment, the structure of the first non-display area (NDA1, FIG. 3A) of the display device (1) not disclosed in FIG. 4d is substantially identical to the structure of the display area (DA) disclosed in FIG. 4d, but the area of ​​the second island portion placed in the first non-display area (NDA1, FIG. 3A) may be larger than the area of ​​the first island portion (11). In this case, one second island portion may correspond to a plurality of first island portions (11) arranged in adjacent rows as described with reference to FIG. 4c. In one embodiment, the structure of the first non-display area (NDA1, FIG. 3a) of the display device (1) not disclosed in FIG. 4d may be substantially the same as the structure of the first non-display area (NDA1) shown in any one of FIG. 4a to 4c. As such, the structure of the first non-display area (NDA1, FIG. 3a) may be selected from various options within the range disclosed in this specification.

[0120] FIG. 4e is a plan view of the IV portion of FIG. 3a as a part of a display device (1) according to one embodiment of the present invention.

[0121] Referring to FIG. 4e, 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) to each other.

[0122] The first opening (CS1) may have a bar shape. The first opening (CS1) may include a first sub-opening (CS1A) extended in a first direction (e.g., x direction or -x direction) and a second sub-opening (CS1B) extended in a second direction (e.g., y direction or -y direction). The first sub-opening (CS1A) and the second sub-opening (CS1B) may each have a bar shape. The first sub-opening (CS1A) and the second sub-opening (CS1B) may have substantially the same width and length. The length of each of the first sub-opening (CS1A) and the second sub-opening (CS1B) represents a value measured along the extension direction, and the width represents a value measured along a direction perpendicular to the length direction (e.g., extension direction).

[0123] 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 sub-non-display area (SNDA1). 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 the first sub-non-display area (SNDA1). Each of the second bridge sections (22) may connect adjacent second island sections (21) to each other. The second bridge sections (22) may be spaced apart from each other by a second opening (CS2) located between the second bridge sections (22).

[0124] The second opening (CS2) may have a bar shape. The second opening (CS2) may include a first sub-opening (CS2A) extended in a first direction (e.g., x direction or -x direction) and a second sub-opening (CS2B) extended in a second direction (e.g., y direction or -y direction). The first sub-opening (CS2A) and the second sub-opening (CS2B) may each have a bar shape. The first sub-opening (CS2A) and the second sub-opening (CS2B) may have substantially the same width and length. Each second island section (21) may be connected to four second bridge sections (22). Each second island section (21) may include drivers of the gate driving circuit (GDC, FIG. 2) described with reference to FIG. 3a. Some of the drivers of the gate driving circuit (GDC, FIG. 2) may also be placed in the second sub-non-display area (SNDA2). For example, some of the third island section (31) may include some drivers.

[0125] 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. 4e 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).

[0126] The display device (1) may include third island sections (31) and third bridge sections (32) disposed in a second sub-non-display area (SNDA2) to connect a display area (DA) and a first sub-non-display area (SNDA1). Adjacent third island sections (31) may be spaced apart from each other by a third opening (CS3) and connected by third bridge sections (32).

[0127] The third opening (CS3) may have a bar shape. The third opening (CS3) may include a first sub-opening (CS3A) extended in a first direction (e.g., x direction or -x direction) and a second sub-opening (CS3B) extended in a second direction (e.g., y direction or -y direction). The first sub-opening (CS3A) and the second sub-opening (CS3B) may each have a bar shape. The first sub-opening (CS3A) and the second sub-opening (CS3B) may have different widths and / or lengths.

[0128] In one embodiment, the length of the first sub-opening (CS3A) of the third opening (CS3) in the first direction (e.g., x direction or -x direction) may be equal to or greater than the length of the second sub-opening (CS3B) of the third opening (CS3) in the second direction (e.g., y direction or -y direction). The width of the first sub-opening (CS3A) of the third opening (CS3) in the second direction (e.g., y direction or -y direction) may be smaller than the width of the second sub-opening (CS3B) of the third opening (CS3) in the first direction (e.g., x direction or -x direction).

[0129] In one embodiment, the length of the first sub-opening (CS3A) of the third opening (CS3) in the first direction (e.g., x direction or -x direction) is equal to the length of the first sub-opening (CS2A) of the second opening (CS2) in the first direction (e.g., x direction or -x direction) and may be greater than the length of the first sub-opening (CS1A) of the first opening (CS1) in the first direction (e.g., x direction or -x direction). The width of the first sub-opening (CS3A) of the third opening (CS3) in the second direction (e.g., y direction or -y direction) may be smaller than the width of the first sub-opening (CS2A) of the second opening (CS2) in the second direction (e.g., y direction or -y direction) and may be equal to the width of the first sub-opening (CS1A) of the first opening (CS1) in the second direction (e.g., y direction or -y direction).

[0130] In one embodiment, the length of the second sub-opening (CS3B) of the third opening (CS3) in the second direction (e.g., y direction or -y direction) is equal to the length of the second sub-opening (CS2B) of the second opening (CS2) in the second direction (e.g., y direction or -y direction) and may be greater than the length of the second sub-opening (CS1B) of the first opening (CS1) in the second direction (e.g., y direction or -y direction). The width of the second sub-opening (CS3B) of the third opening (CS3) in the first direction (e.g., x direction or -x direction) is equal to the width of the second sub-opening (CS2B) of the second opening (CS2) in the first direction (e.g., x direction or -x direction) and may be larger than the width of the second sub-opening (CS1B) of the first opening (CS1) in the first direction (e.g., x direction or -x direction).

[0131] FIG. 5 is a schematic cross-sectional view 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.

[0132] Referring to FIG. 5, 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).

[0133] Looking at the first island section (11), a buffer layer (111) containing an inorganic insulating material is disposed on the substrate (100), and a pixel driving circuit section (PC) may be disposed on the buffer layer (111). An insulating layer (IL) containing an inorganic insulating material and / or an organic insulating material may be disposed between the pixel driving circuit section (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 section (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.

[0134] 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.

[0135] In one embodiment, FIG. 5 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.

[0136] 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.

[0137] 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).

[0138] 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.

[0139] As previously described, the wiring (WL) of the first bridge section (12) may be signal lines (e.g., gate lines, data lines, etc.) for providing electrical signals to transistors included in the pixel driving circuit section (PC) of the first island section (11), or voltage lines (e.g., driving voltage lines, initialization voltage lines, etc.) for providing voltage. An encapsulation layer (300) may also be disposed in the first bridge section (12). In another embodiment, the encapsulation layer (300) may not exist in the first bridge section (12).

[0140] Referring to FIGS. 4a through 4e and FIG. 5, the substrate (100) corresponding to the first island portion (11) and the substrate (100) corresponding to the first bridge portion (12) can be connected to each other. In other words, the plan view shown in FIGS. 4a through 4e above may be substantially the same as the plan view of the substrate (100) in FIG. 5. In other words, the substrate (100) may include an area corresponding to the first island portion (11), an area corresponding to the first bridge portion (12), and an opening (100OP1) having the same shape as the first opening (CS1).

[0141] Similarly, the bag layer (300) corresponding to the first island portion (11) and the bag layer (300) corresponding to the first bridge portion (12) can be connected to each other.

The longest distance (d1) in the first direction (e.g., x direction and / or -x direction) between the second-1st peripheral bridge section (A12ba) and the first center line (CL1) may be the same as the longest distance (d2) in the first direction (e.g., x direction and / or -x direction) between the second-2nd peripheral bridge section (A12bb) and the first center line (CL1).

[0203] The second peripheral island sections (30) may each be positioned across the fourth peripheral area (A4) and the hard area (HA). The second peripheral island sections (30) may extend from the fourth peripheral area (A4) to the hard area (HA). The second peripheral island sections (30) may include a main section (MA) corresponding to the first peripheral island section (A11) and an extension section (EA) extending from the main section (MA) in a second direction (e.g., y direction and / or -y direction) toward the hard area (HA) in the fourth peripheral area (A4). The extension section (EA) may include a first extension section (EA1) positioned in the fourth peripheral area (A4) and a second extension section (EA2) positioned in the hard area (HA). In one embodiment, the first peripheral island section (A11) and the second peripheral island section (30) may have a rectangular shape. For example, the first peripheral island portion (A11) and the second peripheral island portion (30) may have a rectangular shape. The length of the second peripheral island portion (30) in the second direction (e.g., the y direction and / or the -y direction) may be greater than the length of the first peripheral island portion (A11) in the second direction (e.g., the y direction and / or the -y direction). In one embodiment, the second peripheral island portions (30) may be connected to the first portion (40) and formed integrally.

[0204] At least some of the first peripheral island sections (A11), second peripheral island sections (30), first peripheral bridge sections (A12a), and second peripheral bridge sections (A12b) of the fourth peripheral area (A4) may be dummy island sections and / or dummy bridge sections that do not include driving circuits or wiring. Alternatively, at least some of the first peripheral island sections (A11), second peripheral island sections (30), first peripheral bridge sections (A12a), and second peripheral bridge sections (A12b) may include wiring. For example, data lines (DL, FIG. 9) extending from the display area (DA) to the fourth peripheral area (A4) may be arranged in at least some of the first peripheral island sections (A11), second peripheral island sections (30), first peripheral bridge sections (A12a), and second peripheral bridge sections (A12b).

[0205] The display device (1) may include a plurality of first intermediate bridge sections (B12). The plurality of first intermediate bridge sections (B12) may connect one first peripheral island section (A11) and two main island sections (D11) arranged adjacently along a second direction (e.g., y direction and / or -y direction). Each of the plurality of first intermediate bridge sections (B12) may include a first-1 intermediate bridge section (B12a) and a first-2 intermediate bridge section (B12b). The first-1 intermediate bridge section (B12a) and the first-2 intermediate bridge section (B12b) may be arranged to be spaced apart from each other along a first direction (e.g., x direction and / or -x direction). The first-1 intermediate bridge section (B12a) and the first-2 intermediate bridge section (B12b) may be provided with a shape symmetrical to each other.

[0206] One side of each of the pair of first-1 intermediate bridge sections (B12a) and first-2 intermediate bridge sections (B12b) is connected to one of the first peripheral island sections (A11), the other side of the first-1 intermediate bridge section (B12a) is connected to one of the main island sections (D11), and the other side of the first-2 intermediate bridge section (B12b) can be connected to the other main island section (D11). The first-1 intermediate bridge section (B12a) and the first-2 intermediate bridge section (B12b) can be spaced apart from each other with the first intermediate opening (B13a) in between. The first intermediate bridge section (B12) and the first peripheral bridge section (A12a) can be spaced apart from each other with the second intermediate opening (B13b) in between.

[0207] Each of the first-1 intermediate bridge section (B12a) and the first-2 intermediate bridge section (B12b) may have a wavy shape. For example, each of the first-1 intermediate bridge section (B12a) and the first-2 intermediate bridge section (B12b) may have a shape approximately like the letter S. The size and / or width of the first-1 intermediate bridge section (B12a) and the first-2 intermediate bridge section (B12b) may be larger than the size and / or width of the main bridge section (D12). The radius of curvature of the rounded portions of the first-1 intermediate bridge section (B12a) and the first-2 intermediate bridge section (B12b) may be different from the radius of curvature of the rounded portion of the main bridge section (D12). For example, the radius of curvature of the rounded portions of the first-1 intermediate bridge portion (B12a) and the first-2 intermediate bridge portion (B12b) may be larger than the radius of curvature of the rounded portion of the main bridge portion (D12).

[0208] In the first intermediate bridge section (B12) of the intermediate area (BA), wiring extending from the display area (DA) to the fourth peripheral area (A4) may be arranged. For example, data lines (DL, FIG. 6a and FIG. 9) extending from the display area (DA) to the fourth peripheral area (A4) may be arranged in the first intermediate bridge section (B12).

[0209] FIG. 9 is a plan view of part B of FIG. 8a as a part of a display device (1) according to one embodiment of the present invention. FIG. 9 shows a data line (DL) and a fan-out line (FWL) included in the display device (1).

[0210] Referring to FIG. 9, a plurality of data lines (DL) extending from the display area (DA) may be arranged in the fourth peripheral area (A4). The data lines (DL) may extend to the second peripheral island area (30) by passing through the first peripheral island areas (A11) and the second peripheral bridge areas (A12b). FIG. 9 illustrates that six data lines (DL) are arranged in one first peripheral island area (A11), but the present invention is not limited thereto. In other embodiments, five or fewer data lines (DL) may be arranged in one first peripheral island area (A11), or seven or more data lines (DL) may be arranged.

[0211] Fan-out wiring (FWL) may be arranged in the first part (40) of the hard area (HA). Data lines (DL) and fan-out wiring (FWL) may extend from the data driving circuit (DDC, FIG. 3b) toward the display area (DA). Each of the data lines (DL) may include a first data line (DL1) and a second data line (DL2).

[0212] A pair of first data lines (DL1) and second data lines (DL2) may each pass through a plurality of identical first peripheral island sections (A11) and any one identical second peripheral island section (30). The first data line (DL1) may pass through the second-1 peripheral bridge section (A12ba) and the first-1 intermediate bridge section (B12a). The second data line (DL2) may pass through the second-2 peripheral bridge section (A12bb) and the first-2 intermediate bridge section (B12b). The first data line (DL1) is connected to a plurality of main island sections (D11) arranged in one column, and the second data line (DL2) may be connected to a plurality of main island sections (D11) arranged in another column. The first data line (DL1) and the second data line (DL2) may be spaced apart from each other in the second area. The first data line (DL1) and the second data line (DL2) may each be provided in multiple numbers. The number of multiple first data lines (DL1) and the number of multiple second data lines (DL2) may be the same. For example, if the number of multiple data lines is provided in 6 numbers, the number of multiple first data lines (DL1) and the number of multiple second data lines (DL2) may each be provided in 3 numbers. However, this is exemplary, and the number of multiple first data lines (DL1) and multiple second data lines (DL2) is not limited thereto.

[0213] The fan-out wiring (FWL) may include a first fan-out wiring (FWL1) and a second fan-out wiring (FWL2) that are spaced apart from each other. The data line (DL) and the fan-out wiring (FWL) may be electrically connected through a connecting wire (CNL). Multiple connecting wires (CNL) may be provided. One end of the connecting wire (CNL) may be electrically connected to the fan-out wiring (FWL) at the first part (40). The other end of the connecting wire (CNL) may be connected to the data line (DL) at the extension part (EA) of the second peripheral island part (30).

[0214] For example, the connecting wires (CNL) may include a first connecting wire (CNL1) and a second connecting wire (CNL2). The first connecting wire (CNL1) may electrically connect the first data line (DL1) and the first fan-out wire (FWL1). The second connecting wire (CNL2) may electrically connect the second data line (DL2) and the second fan-out wire (FWL2). The first connecting wire (CNL1) may be connected to the first data line (DL1) at the extension (EA) of the second peripheral island section (30). The second connecting wire (CNL2) may be connected to the second data line (DL2) at the extension (EA) of the second peripheral island section (30).

[0215] In one embodiment, the connecting wire (CNL) is placed on the same layer as the data line (DL) and may contain the same material. The connecting wire (CNL) may be placed integrally with the data line (DL). In one embodiment, the connecting wire (CNL) is placed on a different layer from the fan-out wire (FWL) and may be electrically connected to the fan-out wire (FWL) through a contact hole. In one embodiment, the data lines (DL) may be arranged in a straight line or diagonally in the second peripheral island section (30).

[0216] Referring to FIGS. 8a through 9, a plurality of main island sections (D11) are arranged in a tilted structure and a plurality of first peripheral island sections (A11) are arranged in a non-tilting structure, so the space efficiency of the display device (1) can be improved. Accordingly, a plurality of main island sections (D11) and a plurality of first peripheral island sections (A11) can be arranged at a relatively high density. In addition, since the lengths of a plurality of main bridge sections (D12), a plurality of first intermediate bridge sections (B12), a plurality of first peripheral bridge sections (A12a), and a plurality of second peripheral bridge sections (A12b) can be increased, the elongation rate of the display device (1) can be improved.

[0217] Since the plurality of first intermediate bridge sections (B12) are each separated into a first-1 intermediate bridge section (B12a) and a first-2 intermediate bridge section (B12b), the width of the first-1 intermediate bridge section (B12a) and the first-2 intermediate bridge section (B12b) can be relatively reduced. Accordingly, the elongation rate of the display device (1) can be improved.

[0218] Since multiple data lines (DL) are separated into a first data line (DL1) and a second data line (DL2) that are spaced apart from each other, stability can be improved during the process of transmitting data signals to multiple main island sections (D11).

[0219] FIG. 10 is a schematic plan view illustrating a part included in a display device (1) according to one embodiment of the present invention, showing part VⅠ of FIG. 3b.

[0245] The auxiliary processor (1120) may further include data processing circuits such as a data conversion circuit (1122), a gamma correction circuit (1123), and a rendering circuit (1124). The data conversion circuit (1122) receives image data from the controller (1121) and can compensate the image data so that the image is displayed at a desired brightness according to the characteristics of the electronic device (1000) or the user's settings, or can convert the image data to reduce power consumption or compensate for afterimages. The gamma correction circuit (1123) can convert image data or gamma reference voltage, etc. so that the image displayed on the electronic device (1000) has desired gamma characteristics. The rendering circuit (1124) receives image data from the controller (1121) and can render the image data by considering the pixel arrangement of the display device (1) applied to the electronic device (1000).
