[0048] In this specification, terms such as first, second, etc. are used not in a limiting sense, but for the purpose of distinguishing one component from another.

[0049] In this specification, singular expressions include plural expressions unless the context clearly indicates otherwise.

[0050] In this specification, terms such as "include" or "have" mean that the features or components described in the specification exist, and do not preclude the possibility that one or more other features or components may be added.

[0051] In this specification, 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 immediately above the other part, but also cases where another film, region, or component is interposed therein.

[0052] In this specification, when it is stated that a membrane, region, component, etc. is connected, it includes cases where the membrane, region, or component is directly connected, or / or cases where other membranes, regions, or components are interposed between them to form an indirect connection. For example, when it is stated that a membrane, region, or component, etc. is electrically connected in this specification, it indicates cases where the membrane, region, or component, etc. are directly electrically connected, and / or cases where other membranes, regions, or components are interposed between them to form an indirect electrical connection.

[0053] In this specification, "A and / or B" indicates the case where it is A, B, or both A and B. And, "at least one of A and B" indicates the case where it is A, B, or both A and B.

[0054] In this specification, the x-axis, y-axis, and z-axis are not limited to three axes in an orthogonal coordinate system and may 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.

[0055] Where any embodiment in this specification 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 order described.

[0056] 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.

[0057] 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. 2d is a perspective view showing the display device 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.

[0058] 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 completely surround the display area (DA).

[0059] 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).

[0061] 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.

[0062] 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 shows 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), can be protruded along the -z direction (or sunken along the z direction).

[0063] 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.

[0064] FIG. 3 is a schematic plan view of a display device (1) according to an embodiment of the present invention. In this specification, "plan" may mean a view of the display device (1) in the thickness direction (z direction).

[0065] 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. 3 illustrates the placement of a gate driving circuit (GDC) 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).

[0066] 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. 3 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).

[0067] FIG. 3 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.

[0068] 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 (△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). Here, △L is the amount of change in length of the display device, and L represents the initial length of the display device.

[0069] FIGS. 4a to 4c are schematic plan views showing the display area (DA) of a display device (1) according to one embodiment of the present invention.

[0070] Referring to FIG. 4a, the display device (1) may include a plurality of first island portions (11) spaced apart from each other along a first direction (e.g., x direction or -x direction) and a second direction (e.g., y direction or -y direction) in a display area (DA, see FIG. 1), and a plurality of first bridge portions (12) connecting adjacent first island portions (11).

[0071] 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).

[0072] The first bridge sections (12) may be spaced apart from each other by an opening (CS) located between the first bridge sections (12). The first bridge section (12) may have a serpentine shape. For example, as shown in FIG. 4a, the first bridge section (12) may have a shape of approximately the letter 'S'.

[0073] Referring to FIG. 4b, the display device (1) may include a plurality of first island portions (11) spaced apart from each other in a first direction (e.g., x direction or -x direction) and a second direction (e.g., y direction or -y direction) in a display area (DA, see FIG. 1), and a plurality of first bridge portions (12) connecting adjacent first island portions (11). The first bridge portions (12) may be spaced apart from each other by an opening (CS) located between the first bridge portions (12).

[0074] In one embodiment, at least one of the sides of the first island portion (11) may be tilted obliquely with respect to a first direction (e.g., x direction or -x direction) and / or a second direction (e.g., y direction or -y direction). FIG. 4b illustrates that all four sides of the first island portion (11) are tilted obliquely in a clockwise direction.

[0075] 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).

[0076] The first bridge portion (12) may have a wavy shape. For example, as shown in FIG. 4b, the first bridge portion (12) may have a shape of approximately the letter 'S'.

[0077] In one embodiment, the first bridge section (12) may extend substantially parallel to the side of the adjacent first island section (11) as shown in FIG. 4b. For example, the first bridge section (12) may have two rounded sections connected to the adjacent first island sections (11) and a straight section connecting the rounded sections. The straight section of the first bridge section (12) may extend substantially parallel to the side of the adjacent first island section (11).

[0078] Depending on the arrangement of the first island section (11) and / or the structure of the first bridge section (12) described above, the area of ​​the opening (CS) shown in FIG. 4b may be relatively smaller than the area of ​​the opening (CS) shown in FIG. 4a, and thus the display device (1) according to the embodiment shown in FIG. 4a may provide a relatively high-resolution image.

[0079] Referring to FIG. 4c, the display device (1) may include a plurality of first island portions (11) spaced apart from each other along a first direction (e.g., x direction or -x direction) and a second direction (e.g., y direction or -y direction) in a display area (DA, see FIG. 1), and a plurality of first bridge portions (12) connecting adjacent first island portions (11).

[0080] 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).

[0081] The first bridge sections (12) may be spaced apart from each other by an opening (CS) located between the first bridge sections (12). In one embodiment, an opening (CS) approximately H-shaped and an opening (CS) 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 opening (CS).

[0082] In one embodiment, the display device (1) may include a plurality of second island portions 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 non-display area (NDA, see FIG. 1), and a plurality of second bridge portions connecting adjacent second island portions. Accordingly, the non-display area (NDA) of the display device (1) may also be extended in various directions. Each of the second island portions and the second bridge portions may have the same or similar shape as the first island portion (11) and the first bridge portion (12) of the display area (DA) described with reference to FIG. 4a to 4c. In another embodiment of the present invention, the second island portion and the second bridge portion of the non-display area (NDA) may each have a different shape from the first island portion (11) and the first bridge portion (12) of the display area (DA).

[0083] 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.

[0084] 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).

[0085] Looking at the first island section (11), a buffer layer (BF) 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 (BF). 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.

[0086] 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.

[0087] 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, three, or four or more.

[0088] A first organic pattern (OPT1) may be positioned on the light-emitting elements (LEDs) in the first island section (11). The first organic pattern (OPT1) may be arranged continuously along a first direction on the light-emitting elements (LEDs) to serve to support the light-emitting elements (LEDs) from above. Although the first organic pattern (OPT1) is shown as completely covering the upper surface of the light-emitting elements (LEDs) in FIG. 5, substantially, as described later with reference to FIG. 7a to 7c, the first organic pattern (OPT1) may be provided to overlap only partially with the light-emitting elements (LEDs).

[0089] 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. Specifically, the encapsulation layer (300) may be placed on a first organic pattern (OPT1). 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.

[0090] 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).

[0091] 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.

[0092] As previously explained, the wiring (WL) of the first bridge section (12) may be signal lines (e.g., gate lines, data lines, etc.) for providing an electrical signal to a transistor 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 a voltage.

[0093] A third organic pattern (OPT3) may be disposed on the insulating layer (IL) of the first bridge portion (12). The third organic pattern (OPT3) will be described in detail with reference to FIG. 7c.

[0094] A bag layer (300) may also be disposed in the first bridge portion (12). In another embodiment, the bag layer (300) may not be present in the first bridge portion (12).

[0095] Referring to FIGS. 4a through 4c 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 4c 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).

[0096] 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. For example, the plan view shown in FIGS. 4a through 4c above may be substantially identical to the plan view of the bag layer (300). In other words, the bag layer (300) may include an area corresponding to the first island portion (11), an area corresponding to the first bridge portion (12), and an opening (300OP1) having the same shape as the first opening (CS1).

[0097] The circuit-light-emitting element layer (200) between the substrate (100) and the encapsulation layer (300) may include a buffer layer (BF), a pixel driving circuit (PC), wiring (WL), an insulating layer (IL), and a light-emitting element (LED). Similar to the substrate (100), the plan view previously shown in FIGS. 4a through 4c may be substantially identical to the plan view of the circuit-light-emitting element layer (200). In other words, the circuit-light-emitting element layer (200) may include an opening (200OP1) having the same shape as the first opening (CS1).

[0115] The pixel driving circuit (PC) is electrically connected to signal lines and voltage lines. The signal lines may include gate lines such as a first scan line (SL1), a second scan line (SL2), a third scan line (SL3), and a light emission control line (EML), and a data line (DL). The voltage lines may include first and second initialization voltage lines (VIL1, VIL2), a holding voltage line (VSL), and a first voltage line (VDDL).

[0116] The first voltage line (VDDL) can transmit the first power supply voltage (VDD) to the first transistor (T1). The first initialization voltage line (VIL1) can transmit the first initialization voltage (Vint) that initializes the first transistor (T1) to the pixel driving circuit (PC). The second initialization voltage line (VIL2) can transmit the second initialization voltage (Vaint) that initializes the first electrode of the light-emitting element (LED) to the pixel driving circuit (PC). The holding voltage line (VSL) can provide the holding voltage (VSUS) to the second electrode (CE2) of the second node (N2), for example, the storage capacitor (Cst), during the initialization section and the data writing section.

[0117] The first transistor (T1) can be electrically connected to the first voltage line (VDDL) via the fifth transistor (T5) and the eighth transistor (T8), and can be electrically connected to the light-emitting element (LED) via the sixth transistor (T6). The first transistor (T1) acts as a driving transistor and can receive a data signal (Dm) according to the switching operation of the second transistor (T2) and supply driving current to the light-emitting element (LED).

[0118] The second transistor (T2) is electrically connected to the first scan line (SL1) and the data line (DL), and is electrically connected to the first voltage line (VDDL) via the fifth transistor (T5) and the eighth transistor (T8). The second transistor (T2) is turned on according to the first scan signal (GW) received through the first scan line (SL1) and performs a switching operation to transmit the data signal (Dm) transmitted to the data line (DL) to the first node (N1).

[0119] The third transistor (T3) is electrically connected to the first scan line (SL1) and is electrically connected to the light-emitting element (LED) via the sixth transistor (T6). The third transistor (T3) is turned on according to the first scan signal (GW) received through the first scan line (SL1) and connects the first transistor (T1) to the diode, thereby compensating for the threshold voltage of the first transistor (T1).

[0120] The fourth transistor (T4) is electrically connected to the third scan line (SL3) and the first initialization voltage line (VIL1), and is turned on according to the third scan signal (GI) received through the third scan line (SL3) to transmit the first initialization voltage (Vint) from the first initialization voltage line (VIL1) to the gate electrode of the first transistor (T1) to initialize the voltage of the gate electrode of the first transistor (T1). The third scan signal (GI) may correspond to the first scan signal of another pixel driving circuit unit placed in the previous row of the corresponding pixel driving circuit unit (PC).

[0121] The fifth transistor (T5), the sixth transistor (T6), and the eighth transistor (T8) are electrically connected to the light emission control line (EML) and are simultaneously turned on according to the light emission control signal (EM) received through the light emission control line (EML) to form a current path so that driving current can flow from the first voltage line (VDDL) toward the light-emitting element (LED).

[0122] The seventh transistor (T7) is a second initialization transistor and can be electrically connected to the second scan line (SL2), the second initialization voltage line (VIL2), and the sixth transistor (T6). The seventh transistor (T7) is turned on according to the second scan signal (GB) received through the second scan line (SL2) and transmits the second initialization voltage (Vaint) from the second initialization voltage line (VIL2) to the first electrode of the light-emitting element (LED) to initialize the first electrode of the light-emitting element (LED).

[0123] The ninth transistor (T9) can be electrically connected to the second scan line (SL2), the second electrode (CE2) of the storage capacitor (Cst), and the holding voltage line (VSL). The ninth transistor (T9) is turned on according to the second scan signal (GB) received through the second scan line (SL2), and can transmit a holding voltage (VSUS) to the second node (N2), such as the second electrode (CE2) of the storage capacitor (Cst), during the initialization period and the data writing period.

In some embodiments, the eighth transistor (T8) may be turned off and the ninth transistor (T9) may be turned on during the initialization period and the data writing period, and the eighth transistor (T8) may be turned on and the ninth transistor (T9) may be turned off during the light emission period. Since the second node (N2) receives the holding voltage (VSUS) during the initialization period and the data writing period, the uniformity of the brightness of the display device (e.g., LRU, Long Range Uniformity) due to the voltage drop of the first voltage line (VDDL) can be improved.

[0126] The auxiliary capacitor (Ca) can be electrically connected to the sixth transistor (T6), the holding voltage line (VSL), and the first electrode of the light-emitting element (LED). By storing and maintaining a voltage corresponding to the voltage difference between the first electrode of the light-emitting element (LED) and the holding voltage line (VSL) while the seventh transistor (T7) and the ninth transistor (T9) are turned on, the auxiliary capacitor (Ca) can prevent the problem of the black brightness rising when the sixth transistor (T6) is turned off.

[0127] FIGS. 7a to 7c are schematic plan views showing enlarged views of a first island section (11) and a first bridge section (12) arranged in a display area (DA) of a display device (1) according to one embodiment of the present invention.

[0128] Referring to FIG. 7a, a display device (1) according to one embodiment of the present invention includes each first bridge part (12) connected to a first island part (11), and the first island part (11) may include a first organic pattern (OPT1).

[0129] Light-emitting elements (LEDs) corresponding to subpixels may be placed on the first island section (11). Multiple light-emitting elements (LEDs) may be placed spaced apart from each other on one first island section (11). FIGS. 7a to 7c illustrate three light-emitting elements (LEDs) placed on one first island section (11). Each light-emitting element (LED) may emit the same color or emit different colors. For example, the light-emitting elements (LEDs) may each include a first light-emitting diode (230R), a second light-emitting diode (230G), and a third light-emitting diode (230B). The first light-emitting diode (230R) may emit red light, the second light-emitting diode (230G) may emit green light, and the third light-emitting diode (230B) may emit blue light.

[0130] The first organic pattern (OPT1) may be placed on the first to third light-emitting diodes (230R, 230G, 230B). In other words, the first organic pattern (OPT1) may be placed in a planar position with partial overlap with the first to third light-emitting diodes (230R, 230G, 230B). The first organic pattern (OPT1) may be continuously placed on the first to third light-emitting diodes (230R, 230G, 230B) by extending in a first direction (e.g., x direction and / or -x direction). When viewed in a planar position, the first organic pattern (OPT1) may have the shape of a bar or a rectangle with the first direction (e.g., x direction and / or -x direction) as the length direction and the second direction (e.g., y direction and / or -y direction) as the width direction.

[0131] The first organic pattern (OPT1) is integrally provided and arranged to pass over the first to third light-emitting diodes (230R, 230G, 230B) from the top, thereby functioning to physically fix the first to third light-emitting diodes (230R, 230G, 230B). Through this, it is possible to prevent the first to third light-emitting diodes (230R, 230G, 230B) from falling off during subsequent processes such as interlayer patterning and etching after transfer of the first to third light-emitting diodes (230R, 230G, 230B). In addition, due to the characteristics of the display device (1) according to one embodiment of the present invention, it is possible to prevent the first to third light-emitting diodes (230R, 230G, 230B) from falling off due to stress propagation when performing a stretching (extension) operation.

[0132] Each of the first to third light-emitting diodes (230R, 230G, 230B) may include a first electrode (230a) and a second electrode (230b) on the upper side. Each of the first to third light-emitting diodes (230R, 230G, 230B) may have a stacked structure as described later in FIG. 8a, etc., and the first electrode (230a) and the second electrode (230b) may be located at the top of the stacked structure. The first electrode (230a) and the second electrode (230b) may be parts that are electrically connected to a pixel circuit (PC) located on the lower side.

[0133] The first organic pattern (OPT1) may be positioned so as not to overlap with the first electrode (230a) and the second electrode (230b) on a plane. More specifically, the first organic pattern (OPT1) may be positioned to pass between the first electrode (230a) and the second electrode (230b). The first electrodes (230a) of the first to third light-emitting diodes (230R, 230G, 230B) may be positioned in the same row, and the second electrodes (230b) of the first to third light-emitting diodes (230R, 230G, 230B) may also be positioned in the same row spaced apart from the first electrode (230a) in a second direction (e.g., the y direction and / or the -y direction). The first organic pattern (OPT1) may be arranged to extend in a first direction (e.g., x direction and / or -x direction) between the first electrode (230a) and the second electrode (230b).

[0134] The first organic pattern (OPT1) may extend to the edge of the first island portion (11). That is, the end of the first organic pattern (OPT1) and the end of the first island portion (11) may coincide. In another embodiment, the end of the first organic pattern (OPT1) may be spaced apart from the end of the first island portion (11) by a predetermined distance.

[0135] The first organic pattern (OPT1) may include an organic insulating material. For example, the first organic pattern (OPT1) may include a material such as polyimide.

[0136] Referring to FIG. 7b, the first island portion (11) may further include a first organic pattern (OPT1) and a second organic pattern (OPT2).

[0137] The second organic pattern (OPT2) may be positioned to surround the edge of the first island portion (11). In one embodiment, the second organic pattern (OPT2) may have a frame shape that surrounds the edge of the first island portion (11). The second organic pattern (OPT2) may be provided to be in contact with the first organic pattern (OPT1). Thus, since the second organic pattern (OPT2) serves to support the first organic pattern (OPT1) from the outside, it can prevent the first organic pattern (OPT1) from peeling off or lifting.

[0138] The first organic pattern (OPT1) and the second organic pattern (OPT2) may be provided as a single unit. The statement that the first organic pattern (OPT1) and the second organic pattern (OPT2) are provided as a single unit may mean that the first organic pattern (OPT1) and the second organic pattern (OPT2) may be formed through the same process.

[0139] The first organic pattern (OPT1) and the second organic pattern (OPT2) may include the same material. The first organic pattern (OPT1) and the second organic pattern (OPT2) may include an organic insulating material. For example, the first organic pattern (OPT1) and the second organic pattern (OPT2) may include a material such as polyimide.

[0140] Of course, the first organic pattern (OPT1) and the second organic pattern (OPT2) may each be formed by a separate process. In this case, the first organic pattern (OPT1) and the second organic pattern (OPT2) may each contain different materials. In one embodiment, since the first organic pattern (OPT1) passes over the top of each of the first to third light-emitting diodes (230R, 230G, 230B), a material with higher light transmittance than the second organic pattern (OPT2) may be used.

[0141] Referring to FIG. 7c, the first island portion (11) includes a first organic pattern (OPT1) and a second organic pattern (OPT2), and the first bridge portion (12) may further include a third organic pattern (OPT3).

[0142] The third organic pattern (OPT3) may be positioned on top of each first bridge portion (12). As the third organic pattern (OPT3) covers each first bridge portion (12) on the upper surface, it can relieve the stress received by the first bridge portions (12) during the stretching (extension) process.

[0143] The third organic pattern (OPT3) may be arranged to correspond to the entire surface of each first bridge part (12). In other words, the width of the third organic pattern (OPT3) may be the same as the width of the first bridge part (12). The width of the first bridge part (12) may refer to the width of the layers arranged below the third organic pattern (OPT3) in the first bridge part (12). Accordingly, the edge of the third organic pattern (OPT3) may coincide with the edge of the first bridge part (12). In another embodiment, the width of the third organic pattern (OPT3) may be narrower than the width of the first bridge part (12). In this case, the edge of the third organic pattern (OPT3) may be spaced apart from the edge of the first bridge part (12) by a predetermined distance.

[0144] The third organic pattern (OPT3) can be provided integrally with the first organic pattern (OPT1) and the second organic pattern (OPT2). That is, the first organic pattern (OPT1), the second organic pattern (OPT2), and the third organic pattern (OPT3) can be connected in a single layer. The statement that the first organic pattern (OPT1), the second organic pattern (OPT2), and the third organic pattern (OPT3) are provided integrally may mean that the first organic pattern (OPT1), the second organic pattern (OPT2), and the third organic pattern (OPT3) can be formed through the same process.

[0145] The third organic pattern (OPT3) may include the same material as the first organic pattern (OPT1) and the second organic pattern (OPT2). The third organic pattern (OPT3) may include an organic insulator. For example, the third organic pattern (OPT3) may include a material such as polyimide.

[0146] Of course, the third organic pattern (OPT3) may be formed through a separate process from the first organic pattern (OPT1) and the second organic pattern (OPT2), respectively. In this case, the third organic pattern (OPT3) may contain a material different from the first organic pattern (OPT1) and the second organic pattern (OPT2). In one embodiment, since the third organic pattern (OPT3) is located in the first bridge portion (12), it may contain a material with a greater elongation rate compared to the first organic pattern (OPT1) and the second organic pattern (OPT2) located in the first island portion (11).

[0147] FIGS. 8a to 8c are cross-sectional views schematically illustrating a light-emitting element of a display device (1) according to an embodiment of the present invention.

[0148] Referring to FIG. 8a, a light-emitting element (LED) according to one embodiment of the present invention may include an inorganic light-emitting diode comprising an inorganic material. The light-emitting element (LED) may include a first semiconductor layer (231), a second semiconductor layer (232), an intermediate layer (233) between the first semiconductor layer (231) and the second semiconductor layer (232), a first electrode (230a) electrically connected to the first semiconductor layer (231), and a second electrode (230b) electrically connected to the second semiconductor layer (232). The first electrode (230a) and the second electrode (230b) of the light-emitting element (LED) may each be electrically connected to a first electrode pad (241) and a second electrode pad (242) disposed on the same layer. The second electrode pad (242) may be a part of the second voltage line (VSSL, FIG. 5a) or a conductive layer electrically connected to the second voltage line (VSSL, FIG. 5a).

[0149] In one embodiment, the first semiconductor layer (231) may include a p-type semiconductor layer. The p-type semiconductor layer is In x AlyGa 1-x-yA semiconductor material having the composition formula N (0≤x≤1, 0≤y≤1, 0≤x+y≤1) can be selected from, for example, GaN, AlN, AlGaN, InGaN, InN, InAlGaN, AlInN, etc., and p-type dopants such as Mg, Zn, Ca, Sr, and Ba can be doped.

[0150] The second semiconductor layer (232) may include, for example, an n-type semiconductor layer. The n-type semiconductor layer is In x AlyGa 1-x-y A semiconductor material having the composition formula N (0≤x≤1, 0≤y≤1, 0≤x+y≤1) can be selected from, for example, GaN, AlN, AlGaN, InGaN, InN, InAlGaN, AlInN, etc., and can be doped with n-type dopants such as Si, Ge, and Sn.

[0151] The intermediate layer (233) is a region where electrons and holes recombine, and as electrons and holes recombine, they transition to a lower energy level and can generate light having a corresponding wavelength. The intermediate layer (233) is, for example, In x Al y Ga 1-x-y It can be formed by including a semiconductor material having a composition formula of N (0≤x≤1, 0≤y≤1, 0≤x+y≤1), and can be formed as a single quantum well structure or a multi-quantum well (MQW) structure. In addition, it may include a quantum wire structure or a quantum dot structure.

[0152] FIG. 8a illustrates that the first semiconductor layer (231) includes a p-type semiconductor layer and the second semiconductor layer (232) includes an n-type semiconductor layer, but the present invention is not limited thereto. In another embodiment, the first semiconductor layer (231) may include an n-type semiconductor layer and the second semiconductor layer (232) may include a p-type semiconductor layer.

[0153] FIG. 8a illustrates that the first electrode pad (241) and the second electrode pad (242) are disposed on the same layer, but the present invention is not limited thereto. The first electrode pad (241) and the second electrode pad (242) may be disposed on different layers.

[0154] The first electrode (230a) and the second electrode (230b) of the light-emitting element (LED) may face in the same direction, but may face in the +z direction. The first electrode (230a) and the second electrode (230b) may be placed on a stacked structure of a first semiconductor layer (231), an intermediate layer (233), and a second semiconductor layer (232). On a plane, the first electrode (230a) and the second electrode (230b) may have a structure in which they are spaced apart at a predetermined distance and placed adjacent to each other, such as a horizontal (lateral) diode structure. Since this horizontal (lateral) diode structure does not use pressure during transfer, it can prevent physical damage to the lower layers or circuit structure.

[0155] A light-emitting element (LED) can be attached to the first electrode pad (241) and the second electrode pad (242) using an adhesive layer (251). In another embodiment, the adhesive layer (251) may be omitted depending on the case.

[0156] In one embodiment, a protective film (253) may be placed on the outer edge of a light-emitting element (LED). The protective film (253) may include an organic insulating material and / or an inorganic insulating material. The protective film (253) may include, for example, polyimide. In another embodiment, the protective film (253) may be omitted depending on the case.

[0157] An organic insulating film (130) may be disposed on the first electrode pad (241) and the second electrode pad (242). The organic insulating film (130) may have a first contact hole (CNT1) and a second contact hole (CNT2) (see FIG. 10) that expose at least a portion of each of the first electrode pad (241) and the second electrode pad (242). The organic insulating film (130) may include, for example, polyimide. At least a portion of the light-emitting element (LED) may be a structure in which it is surrounded and embedded by the organic insulating film (130). FIG. 8a illustrates a structure in which at least a portion of a stacked structure including a first semiconductor layer (231), a second semiconductor layer (232), and an intermediate layer (233) is embedded in the organic insulating film (130). In this case as well, the first electrode (230a) and the second electrode (230b) of the light-emitting element (LED) may protrude in the +z direction above the upper surface of the organic insulating film (130).

[0158] The first electrode pad (241) and the first electrode (230a) of the light-emitting element (LED) can be electrically connected through the first contact electrode (CMa), and the second electrode pad (242) and the second electrode (230b) of the light-emitting element (LED) can be electrically connected through the second contact electrode (CMb). One end of the first contact electrode (CMa) can be connected to the first electrode pad (241) through a first contact hole (CNT1) that exposes at least a portion of the first electrode pad (241), and the other end can be connected to the first electrode (230a). Additionally, one end of the second contact electrode (CMb) can be connected to the second electrode pad (242) through a second contact hole (CNT2) that exposes at least a portion of the second electrode pad (242), and the other end can be connected to the second electrode (230b).

[0159] The first contact electrode (CMa) and the second contact electrode (CMb) may include a conductive material including molybdenum (Mo), aluminum (Al), copper (Cu), titanium (Ti), etc., and may be formed as a multilayer or single layer including the above materials. Alternatively, the first contact electrode (CMa) and the second contact electrode (CMb) may include a transparent conductive material. For example, the first contact electrode (CMa) and the second contact electrode (CMb) may include a transparent conducting oxide (TCO) such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium oxide (In2O3), indium gallium oxide (IGO), or aluminum zinc oxide (AZO).

[0160] The first organic pattern (OPT1) may be placed between the first electrode (230a) and the second electrode (230b). FIG. 8a discloses that the first organic pattern (OPT1) is located on the protective film (253). In another embodiment, if the protective film (253) is not provided, the first organic pattern (OPT1) may be placed directly on the first semiconductor layer (231) and / or the second semiconductor layer (232). Or in another embodiment, an organic insulating film (130) may cover the top of the first semiconductor layer (231) and / or the second semiconductor layer (232), and the first organic pattern (OPT1) may be placed on this organic insulating film (130).

[0161] Meanwhile, as shown in FIG. 8a, the first organic pattern (OPT1) may be placed across the step formed by the first semiconductor layer (231) and the intermediate layer (233). Alternatively, as shown in FIG. 8c, the first organic pattern (OPT1) may be placed on the second semiconductor layer (232) (or the first semiconductor layer (231)) with a flattened upper surface.

[0162] The width (w1) of the first organic pattern (OPT1) may be equal to or narrower than the distance (d1) between the first electrode (230a) and the second electrode (230b). The width (w1) may be measured in the same direction as the distance (d1). Thus, the first organic pattern (OPT1) may overlap with a part of the light-emitting element (LED) on a plane.

[0163] As a comparative example, it can be assumed that the first organic pattern overlaps with the entire light-emitting element (LED) rather than with a part of the light-emitting element (LED). However, in this case, a problem may arise in which the light efficiency emitted from the light-emitting element (LED) is reduced due to the light transmittance and refractive index of the material layer forming the first organic pattern. Therefore, in the display device (1) according to one embodiment of the present invention, the first organic pattern (OPT1) is provided to overlap with a part of the light-emitting element (LED), thereby supporting the light-emitting elements (LED) from above while minimizing the reduction in light efficiency of the light-emitting elements (LED).

[0164] Referring to FIG. 8b, the second organic pattern (OPT2) may be positioned on the organic insulating film (130). The second organic pattern (OPT2) may be arranged to surround the edge of the first island portion (11). As shown in FIG. 7b, the second organic pattern (OPT2) may have a frame shape that surrounds the edge of the first island portion (11). The second organic pattern (OPT2) may be provided to be in contact with the first organic pattern (OPT1). Thus, the second organic pattern (OPT2) serves to support the first organic pattern (OPT1) from the outside, thereby preventing the first organic pattern (OPT1) from peeling off or lifting.

[0165] The second organic pattern (OPT2) may be spaced apart from the first contact hole (CNT1) and the second contact hole (CNT2) defined in the organic insulating film (130) by a predetermined distance. One end of the second organic pattern (OPT2) may coincide with the edge of the first island portion (11). This can be understood as being because the second organic pattern (OPT2) is also patterned together during patterning to form the first island portion (11) and the first bridge portion (12).

[0166] FIG. 9 is a schematic cross-sectional view showing an enlarged portion of a display device (1) according to one embodiment of the present invention.

[0167] Referring to FIG. 9, in one embodiment, a residue layer (rd) may be located between the first electrode (230a) and the second electrode (230b). The residue layer (rd) may be located on the stepped portion of the first electrode (230a) on the first semiconductor layer (231) and / or on the stepped portion of the second electrode (230b) on the second semiconductor layer (232). In FIG. 9, the residue layer (rd) is shown as being located on a protective film (253) placed on the outer edge of the light-emitting element (LED); however, if the protective film (253) is not provided, the residue layer (rd) may be in contact with a portion of the upper surface of the first semiconductor layer (231) and a portion of the side of the first electrode (230a), and may be in contact with a portion of the upper surface of the second semiconductor layer (232) and a portion of the side of the second electrode (230b).

[0168] In one embodiment, the residue layer (rd) may be formed in a patterning process, i.e., a hard mask process, to form the first island portion (11) and the first bridge portion (12). The first electrode (230a) and the second electrode (230b) have a predetermined thickness, and due to the resulting step difference, residue that was not completely removed in the etching process may be generated. Accordingly, the residue layer (rd) may contain the same material as the material used in the hard mask process. The residue layer (rd) may include, for example, a transparent conducting oxide (TCO) such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium oxide (In2O3), indium gallium oxide (IGO), or aluminum zinc oxide (AZO).

[0169] As the first organic pattern (OPT1) is positioned between the first electrode (230a) and the second electrode (230b), a short circuit between the first electrode (230a) and the second electrode (230b) can be prevented due to residue of the residue layer (rd). In some embodiments, the thickness (t1) of the first organic pattern (OPT1) may be thicker than the thicknesses (t2, t3) of the first electrode (230a) and the second electrode (230b), respectively. In some embodiments, the upper surface of the first organic pattern (OPT1) may be positioned raised above the upper surface of the first electrode (230a) and the second electrode (230b), respectively, from the substrate (100, see FIG. 5).

[0170] FIG. 10 is a cross-sectional view schematically showing a part of the display area of ​​a display device (1) according to one embodiment of the present invention.

[0171] Referring to FIG. 10, a first island portion (11) and a first bridge portion (12) of a display device (1) according to one embodiment of the present invention may be spaced apart with an opening (CS) in between. The first island portion (11) includes a light-emitting element (LED) and a pixel circuit (PC) electrically connected to the light-emitting element (LED), and the first bridge portion (12) may include wiring (WL) electrically connected to the pixel circuit (PC) placed in the first island portion (11).

[0172] The substrate (100) may include an island region (100a) corresponding to a first island portion (11) and a bridge region (100b) corresponding to a first bridge portion (12). In one embodiment, the substrate (100) may have a multilayer structure including base layers (101, 105) comprising a polymer resin and barrier layers (103, 107) comprising an inorganic insulating material. For example, the substrate (100) may include a first base layer (101), a second base layer (105) on the first base layer (101), a first barrier layer (103) between the first base layer (101) and the second base layer (105), and a second barrier layer (107) on the second base layer (105). The first base layer (101) and the second base layer (105) may comprise a polymer resin, and the first barrier layer (103) and the second barrier layer (107) may comprise an inorganic insulating material. The first barrier layer (103) and the second barrier layer (107) may have an isolated shape disposed in the first island portion (11). That is, in a planar view, the first barrier layer (103) and the second barrier layer (107) may not overlap with the bridge area (100b).

[0173] Looking first at the first island portion (11), a pixel circuit (PC) may be disposed on the second barrier layer (107). The pixel circuit (PC) may include a first thin-film transistor (TFT1), a second thin-film transistor (TFT2), and a storage capacitor (Cst). Each of the first thin-film transistor (TFT1) and the second thin-film transistor (TFT2) may include a semiconductor layer (Act), a gate electrode (GE), a source electrode (SE), and a drain electrode (DE). In one embodiment, the first thin-film transistor (TFT1) may be a driving transistor, and the second thin-film transistor (TFT2) may be a switching transistor. FIG. 10 illustrates that the first thin-film transistor (TFT1) and the second thin-film transistor (TFT2) are each of the top gate type, with the gate electrode (GE) disposed on the semiconductor layer (Act) with the gate insulating layer (111) in between; however, according to another embodiment, the first thin-film transistor (TFT1) and the second thin-film transistor (TFT2) may each be of the bottom gate type.

[0174] Inorganic insulating layers constituting an inorganic insulating stack (IIL) may be disposed between the semiconductor layer (Act) and the conductive layer constituting the pixel circuit (PC). The inorganic insulating stack (IIL) may include a gate insulating layer (111), a first interlayer insulating layer (113), and a second interlayer insulating layer (115). Each of the gate insulating layer (111), the first interlayer insulating layer (113), and the second interlayer insulating layer (115) may include an inorganic insulating material such as silicon oxide, silicon nitride, silicon oxynitride, aluminum oxide, titanium oxide, etc., and may be a single layer or a multilayer containing the aforementioned material.

[0175] The semiconductor layer (Act) may include polysilicon. Alternatively, the semiconductor layer (Act) may include amorphous silicon, an oxide semiconductor, an organic semiconductor, etc. The gate electrode (GE) may include a metal thin film composed of a low-resistance metal material. The gate electrode (GE) may include a conductive material including molybdenum (Mo), aluminum (Al), copper (Cu), titanium (Ti), etc., and may be formed as a multilayer or single layer including the above materials. For example, the gate electrode (GE) may include a metal thin film formed as a triple layer with a titanium (Ti) / aluminum (Al) / titanium (Ti) structure. A gate insulating layer (111) may be disposed between the semiconductor layer (Act) and the gate electrode (GE).

[0176] The source electrode (SE) and the drain electrode (DE) may be located on the same layer, for example, the second interlayer insulating layer (115), and may contain the same material. The source electrode (SE) and the drain electrode (DE) may contain a metal thin film composed of a low-resistance metal material. The source electrode (SE) and the drain electrode (DE) may contain a conductive material including molybdenum (Mo), aluminum (Al), copper (Cu), titanium (Ti), etc., and may be formed as a multilayer or single layer containing the above materials. For example, the source electrode (SE) and the drain electrode (DE), like the gate electrode (GE), may be provided with a metal thin film formed as a triple layer of titanium (Ti) / aluminum (Al) / titanium (Ti) structure.

[0177] The storage capacitor (Cst) may include a first electrode (CE1) and a second electrode (CE2) that overlap with the first interlayer insulating layer (113) in between. The storage capacitor (Cst) may overlap with the first thin-film transistor (TFT1) in a planar plane. In this regard, FIG. 10 illustrates that the gate electrode (GE) of the first thin-film transistor (TFT1) is integrally formed with the first electrode (CE1) of the storage capacitor (Cst). In another embodiment, the storage capacitor (Cst) may not overlap with the thin-film transistor (TFT) in a planar plane. The storage capacitor (Cst) may be covered by the second interlayer insulating layer (115).

[0178] The second electrode (CE2) of the storage capacitor (Cst) may include a conductive material and may be formed as a multilayer or single layer. The second electrode (CE2) may include a metal thin film composed of a low-resistance metal material. The second electrode (CE2) may include a conductive material including molybdenum (Mo), aluminum (Al), copper (Cu), titanium (Ti), etc., and may be formed as a multilayer or single layer including the above materials. For example, the second electrode (CE2) may be provided with a metal thin film formed as a triple layer of a titanium (Ti) / aluminum (Al) / titanium (Ti) structure.

[0179] A first organic insulating stack (OILa) may be disposed on an inorganic insulating stack (IIL). The first organic insulating stack (OILa) may include a first organic insulating layer (123), a second organic insulating layer (124), and a third organic insulating layer (125). The first organic insulating layer (123), the second organic insulating layer (124), and the third organic insulating layer (125) may include an organic insulating material and may be formed as a multilayer or a single layer.

[0180] The first organic insulating layer (123) may be disposed on the source electrode (SE) and the drain electrode (DE). A third contact electrode (CM1) may be disposed on the first organic insulating layer (123). The third contact electrode (CM1) may be electrically connected to the drain electrode (DE) of the first thin-film transistor (TFT1) through a contact hole penetrating the first organic insulating layer (123). The third contact electrode (CM1) may include a conductive material including molybdenum (Mo), aluminum (Al), copper (Cu), titanium (Ti), etc., and may be formed as a multilayer or single layer including the above materials.

[0181] A second organic insulating layer (124) may be disposed on the third contact electrode (CM1), and a second voltage line (VSSL) may be disposed on the second organic insulating layer (124). The second voltage line (VSSL) may be electrically connected to the second electrode of the light-emitting element (LED) to supply a second power supply voltage (VSS). The second voltage line (VSSL) may include a conductive material including molybdenum (Mo), aluminum (Al), copper (Cu), titanium (Ti), etc., and may be formed as a multilayer or single layer including the above materials.

[0182] A third organic insulating layer (125) may be disposed on the second voltage line (VSSL), and a first electrode pad (241) and a second electrode pad (242) may be disposed on the third organic insulating layer (125). The first electrode pad (241) may be electrically connected to the third contact electrode (CM1) through a contact hole penetrating the second organic insulating layer (124) and the third organic insulating layer (125). The second electrode pad (242) may be electrically connected to the second voltage line (VSSL) through a contact hole penetrating the third organic insulating layer (125).

[0183] A light-emitting element (LED) may be placed on the first electrode pad (241) and the second electrode pad (242). The structure of the light-emitting element (LED) is as described above with reference to FIG. 8a. The light-emitting element (LED) may be attached to the first electrode pad (241) and the second electrode pad (242) using an adhesive layer (251).

[0184] An organic insulating film (130) may be disposed on a first electrode pad (241) and a second electrode pad (242). The organic insulating film (130) covers the first electrode pad (241) and the second electrode pad (242) and may have a first contact hole (CNT1) and a second contact hole (CNT2) that expose at least a portion of each of the first electrode pad (241) and the second electrode pad (242). At least a portion of a light-emitting element (LED) may be disposed in the organic insulating film (130) so as to be embedded therein.

[0185] The first electrode (230a) and the second electrode (230b) of the light-emitting element (LED) may protrude onto the upper surface of the organic insulating film (130). In other words, the first electrode (230a) and the second electrode (230b) may be arranged to protrude in the +z direction. On a plane, the first electrode (230a) and the second electrode (230b) may have a structure in which they are spaced apart at a predetermined distance and positioned adjacent to each other, such as a horizontal (lateral) diode structure. Since this horizontal diode structure does not use pressure during transfer, it can prevent physical damage to the lower layers or circuit structure.

[0186] The first electrode (230a) of the light-emitting element (LED) can be electrically connected to the pixel circuit (PC) through the first contact electrode (CMa), the first electrode pad (241), and the third contact electrode (CM1). The second electrode (230b) of the light-emitting element (LED) can be electrically connected to the second voltage line (VSSL) through the second contact electrode (CMb) and the second electrode pad (242).

[0187] The first organic pattern (OPT1) may be placed between the first electrode (230a) and the second electrode (230b). The first organic pattern (OPT1) may be placed to continuously pass over the top of the first to third light-emitting diodes (230R, 230G, 230B), as illustrated in FIG. 7c, etc. By doing so, the first to third light-emitting diodes (230R, 230G, 230B) may be prevented from falling off during subsequent processes such as interlayer patterning and etching after transfer of the first to third light-emitting diodes (230R, 230G, 230B). In addition, due to the characteristics of the display device (1) according to one embodiment of the present invention, it may be possible to prevent the first to third light-emitting diodes (230R, 230G, 230B) from falling off due to stress propagation when performing a stretching (extension) operation.

[0188] The second organic pattern (OPT2) may be placed on the organic insulating film (130) and arranged around the edge of the first island portion (11). The second organic pattern (OPT2) may be arranged at a predetermined distance from the first contact hole (CNT1) and the second contact hole (CNT2). The second organic pattern (OPT2) may be connected to the first organic pattern (OPT1) as shown in FIG. 7c, etc., and may be provided integrally.

[0189] In some embodiments, an encapsulation layer (300) may be disposed on a first organic pattern (OPT1) and a second organic pattern (OPT2). The encapsulation layer (300) may be disposed to cover the first organic pattern (OPT1), the second organic pattern (OPT2), and the light-emitting element (LED) from the front. 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 another embodiment, the encapsulation layer (300) may include an organic material such as resin.

[0190] The first island portion (11) of the display device (1) may represent a stacked structure extending from the island region (100a) of the substrate (100) to the encapsulation layer (300) disposed on the island region (100a). In this specification, the upper surface refers to the surface on which an image is displayed in the display device (1), i.e., the surface facing the substrate (100). In FIG. 10, the first island portion (11) may be the upper surface of the encapsulation layer (300).

[0191] Looking at the first bridge portion (12), only base layers may be disposed in the bridge region (100b) of the substrate (100). For example, only the first base layer (101) and the second base layer (105) may be disposed in the bridge region (100b), and the first barrier layer (103) and the second barrier layer (107) may be spaced apart from the bridge region (100b) and not overlapped on the plane.

[0192] A second organic insulating stack (OILb) may be disposed on a bridge region (100b) of a substrate (100). The second organic insulating stack (OILb) may include a first organic insulating layer (123), a second organic insulating layer (124), a third organic insulating layer (125), and a fourth organic layer (121). The first organic insulating layer (123), the second organic insulating layer (124), and the third organic insulating layer (125) of the second organic insulating stack (OILb) may be formed through the same process as the first organic insulating layer (123), the second organic insulating layer (124), and the third organic insulating layer (125) of the first organic insulating stack (OILa). Since the bridge region (100b) does not include an inorganic insulating stack (IIL), the second organic insulating stack (OILb) may further include a fourth organic layer (121) to level with the upper surface of the inorganic insulating stack (IIL). In one embodiment, the first island portion (11) may further include a fourth organic layer (121), and the fourth organic layer (121) may be positioned to cover the side of the inorganic insulating stack (IIL) having an isolated shape. The fourth organic layer (121) may include an organic insulating material and may be formed as a multilayer or a single layer.

[0193] First wiring lines (WL1) may be disposed on the fourth organic layer (121), second wiring lines (WL2) may be disposed on the first organic insulating layer (123), and third wiring lines (WL3) may be disposed on the second organic insulating layer (124). Each of the first wiring lines (WL1), second wiring lines (WL2), and third wiring lines (WL3) may be a signal line (e.g., gate line, data line, etc.) for providing an electrical signal to a transistor included in the pixel circuit (PC) of the first island portion (11) as described above, or a voltage line (e.g., power supply voltage line, initialization voltage line, etc.) for providing a voltage. The wiring lines (WL) may include a conductive material including molybdenum (Mo), aluminum (Al), copper (Cu), titanium (Ti), etc., and may be formed as a multilayer or single layer including the above materials.

[0194] The wiring (WL) can be placed within the wiring area (WA). The width of the wiring area (WA) may be narrower than the width of the bridge area (100b). For example, the edge of the wiring area (WA) may be spaced inward from the edge of the bridge area (100b). FIG. 10 illustrates that the edge of the wiring area (WA) is spaced inward by a first distance (d1) from both edges of the bridge area (100b).

[0195] A sealing layer (300) may be disposed on the second organic insulating stack (OILb). The sealing layer (300) may include a structure in which an inorganic sealing layer containing an inorganic insulating material, an organic sealing layer containing an organic insulating material, and an inorganic sealing layer containing an inorganic insulating material are laminated. In another embodiment, the sealing layer (300) may include an organic material such as resin.

[0196] The first bridge portion (12) of the display device (1) may represent a stacked structure from the bridge region (100b) of the substrate (100) to the encapsulation layer (300) disposed on the bridge region (100b). The upper surface of the first bridge portion (12) may be the upper surface of the encapsulation layer (300).

[0197] FIGS. 11a to 11f are cross-sectional views schematically illustrating the manufacturing process of a display device (1) according to one embodiment of the present invention.

[0198] First, referring to FIG. 11a, a first electrode pad (241) and a second electrode pad (242) can be formed on the third organic insulating layer (125). Although the lower structure of the third organic insulating layer (125) is omitted, it may have the same structure as described above with reference to FIG. 10.

[0199] An adhesive layer (251) is disposed on the first electrode pad (241) and the second electrode pad (242), and a light-emitting element (LED) can be attached to the first electrode pad (241) and the second electrode pad (242) using the adhesive layer (251).

[0200] Then, referring to FIG. 11b, an organic insulating film (130) may be formed to cover the first electrode pad (241) and the second electrode pad (242). A portion of the light-emitting element (LED) may be embedded by the organic insulating film (130).

[0201] Then, referring to FIG. 11c, a first contact hole (CNT1) and a second contact hole (CNT2) can be formed in the organic insulating film (130). A portion of the organic insulating film (130) is removed to form the first contact hole (CNT1) and the second contact hole (CNT2), and at least a portion of the first electrode pad (241) and the second electrode pad (242) may be exposed in correspondence with the first contact hole (CNT1) and the second contact hole (CNT2).

[0202] Then, referring to FIG. 11d, the first contact electrode (CMa) and the second contact electrode (CMb) can be patterned so that the first electrode pad (241) and the first electrode (230a) are electrically connected, and the second electrode pad (242) and the second electrode (230b) are electrically connected to each other. One end of the first contact electrode (CMa) can be connected to the first electrode pad (241) exposed through the first contact hole (CNT1), and the other end of the first contact electrode (CMa) can be connected to the first electrode (230a). One end of the second contact electrode (CMb) can be connected to the second electrode pad (242) exposed through the second contact hole (CNT2), and the other end of the second contact electrode (CMb) can be connected to the second electrode (230b).

[0203] Referring to FIG. 11e, a hard mask process may be performed thereafter. A hard mask layer (HML) may be formed to completely cover the top of the light-emitting element (LED). The hard mask layer (HML) may include a transparent conductive material. For example, the hard mask layer (HML) may include a transparent conducting oxide (TCO) such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium oxide (In2O3), indium gallium oxide (IGO), or aluminum zinc oxide (AZO).

[0204] Through a hard mask process, the substrate (100, see FIG. 5) can be patterned into a first island portion (11) and a first bridge portion (12). In other words, through a hard mask process, the portions and layers of the substrate (100) corresponding to the first opening (CS1) are removed, and the shape of the first island portion (11) and the first bridge portion (12) can be realized.

[0205] Referring to FIG. 11f, after the hard mask process is completed, the hard mask layer (HML) can be removed. Then, a first organic pattern (OPT1) can be formed on the light-emitting element (LED). The first organic pattern (OPT1) can be patterned to pass between the first electrode (230a) and the second electrode (230b) of the light-emitting element (LED).

[0206] Additionally, a second organic pattern (OPT2) and a third organic pattern (OPT3) may be formed on the organic insulating film (130). The first organic pattern (OPT1), the second organic pattern (OPT2), and the third organic pattern (OPT3) may be formed by the same process. In other words, the first organic pattern (OPT1), the second organic pattern (OPT2), and the third organic pattern (OPT3) may be patterned while leaving the first organic pattern (OPT1), the second organic pattern (OPT2), and the third organic pattern (OPT3) after an organic material layer (not shown) for forming them is formed on the entire surface of the substrate (100). Accordingly, the first organic pattern (OPT1), the second organic pattern (OPT2), and the third organic pattern (OPT3) may be formed as a single unit.

[0207] FIGS. 12a to 12c are cross-sectional views schematically illustrating the manufacturing process of a display device (1) according to one embodiment of the present invention.

[0208] In this embodiment, the process from FIGS. 11a to 11c is the same as described above, but there is a difference in the subsequent process. In FIGS. 12a to 12c, a first organic pattern (OPT1), etc., may be formed before the hard mask process.

[0209] Referring to FIG. 12a, a first contact electrode (CMa) and a second contact electrode (CMb) can be formed. The first contact electrode (CMa) and the second contact electrode (CMb) can be formed by the same process as described with reference to FIG. 11d. After that, a first organic pattern (OPT1) can be formed on the light-emitting element (LED). The first organic pattern (OPT1) can be patterned to pass between the first electrode (230a) and the second electrode (230b) of the light-emitting element (LED). Additionally, a second organic pattern (OPT2) and a third organic pattern (OPT3) can be formed on the organic insulating film (130).

[0210] Referring to FIG. 12b, a hard mask process may be performed thereafter. A hard mask layer (HML) may be formed on a first organic pattern (OPT1), a second organic pattern (OPT2), and a third organic pattern (OPT3). The hard mask layer (HML) may be formed to completely cover the first organic pattern (OPT1), the second organic pattern (OPT2), and the third organic pattern (OPT3), as well as the light-emitting element (LED). Through the hard mask process, the substrate (100, see FIG. 5) may be patterned into a first island portion (11) and a first bridge portion (12). In other words, through the hard mask process, portions and layers of the substrate (100) corresponding to the first opening (CS1) are removed, and the shape of the first island portion (11) and the first bridge portion (12) may be realized.

[0211] Referring to Fig. 12c, after the hard mask process is completed, the hard mask layer (HML) can be removed.

In the manufacturing process described with reference to FIGS. 12a to 12c, a first organic pattern (OPT1) may be formed before the hard mask process. By placing the first organic pattern (OPT1) between the first electrode (230a) and the second electrode (230b), a short circuit between the first electrode (230a) and the second electrode (230b) can be prevented due to a residue that remains as a residue layer (rd, see FIG. 9) between the first electrode (230a) and the second electrode (230b) without removing a portion of the hard mask layer (HML) between the first electrode (230a) and the second electrode (230b).
