[0096] For convenience of explanation, the following description will focus on the case where the display device (1) has a structure as shown in FIG. 4b.

[0097] FIG. 5 is a cross-sectional view schematically showing a first island part (11) and a first bridge part (12) arranged in a display area (DA) of a display device (1) according to one embodiment of the present invention.

[0098] 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.

[0099] 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.

In other words, the circuit-light-emitting element layer (200) may include an opening (200OP1) having the same shape as the first opening (CS1).

[0154] The first interlayer insulating layer (205) and the second interlayer insulating layer (207) may include an inorganic insulating material such as silicon oxide, silicon nitride, or silicon oxynitride, and may be a single layer or a multilayer containing the aforementioned inorganic insulating material. The first and second transistors (T1, T2) and the storage capacitor (Cst) may be covered by the first organic insulating layer (209).

[0155] A second organic insulating layer (211) and a third organic insulating layer (213) may be sequentially disposed on the first organic insulating layer (209). The first organic insulating layer (209), the second organic insulating layer (211), and the third organic insulating layer (213) may include an organic insulating material. The organic insulating material may include, for example, general-purpose polymers such as polymethylmethacrylate (PMMA) or polystyrene (PS), polymer derivatives having a phenolic group, acrylic polymers, imide polymers, aryl ether polymers, amide polymers, fluorine polymers, p-xylene polymers, vinyl alcohol polymers, and blends thereof.

[0156] The second voltage line (VSSL) may be placed on the second organic insulating layer (211). Although not illustrated, the first voltage line (VDDL, FIG. 6a to 6c) may be placed on the first organic insulating layer (209) or on the second organic insulating layer (211).

[0157] The first electrode pad (241) may be disposed on the third organic insulating layer (213). The first electrode pad (241) may be connected to the second contact metal (CM2) through the first contact hole (CNT1), and the second contact metal (CM2) may be connected to the first contact metal (CM1) through the third contact hole (CNT3). FIG. 8 illustrates the first electrode pad (241) being electrically connected to the first transistor (T1) through the first and second contact metals (CM1, CM2), but the present invention is not limited thereto. As described with reference to FIGS. 6b and 6c, the pixel driving circuit (PC) may further include a sixth transistor (T6, FIGS. 6b and 6c), in which case the first electrode pad (241) may be electrically connected to the sixth transistor (T6, FIGS. 6b and 6c) through the first and second contact metals (CM1, CM2). The sixth transistor (T6, FIGS. 6b and 6c) may have substantially the same structure as the first transistor (T1).

[0158] The second electrode pad (242) may be placed on the same layer as the first electrode pad (241), for example, on the third organic insulating layer (213). The second electrode pad (242) may be electrically connected to the second voltage line (VSSL) through the second contact hole (not shown).

[0159] The light-emitting diode (230) may be an inorganic light-emitting diode. For example, the light-emitting diode (230) may include a first semiconductor layer (231), a second semiconductor layer (232), an intermediate layer (233) between the first semiconductor layer (231) and the second semiconductor layer (232), a first electrode (235) electrically connected to the first semiconductor layer (231), and a second electrode (238) electrically connected to the second semiconductor layer (232).

[0160] The first semiconductor layer (231) may include, for example, a p-type semiconductor layer. The p-type semiconductor layer is In x Al y Ga 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 p-type dopants such as Mg, Zn, Ca, Sr, and Ba can be doped.

[0161] The second semiconductor layer (232) may include, for example, an n-type semiconductor layer.

[0162] 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, Inx 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.

[0163] FIG. 8 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.

[0164] The first electrode (235) and the second electrode (238) of the light-emitting diode (230) can be electrically connected to the first electrode pad (241) and the second electrode pad (242), respectively, through the bump metal (250).

[0165] The light-emitting diode (230) can be electrically connected to the first electrode pad (241) and the second electrode pad (242) by placing a bump metal (250) on each of the first electrode pad (241) and the second electrode pad (242), applying a predetermined amount of heat, and then placing the light-emitting diode (230) under a predetermined amount of pressure. For example, the light-emitting diode (230) can be electrically connected to the first electrode pad (241) through a first bump metal (250A) between the light-emitting diode (230) and the first electrode pad (241). The light-emitting diode (230) can be electrically connected to the second electrode pad (242) through a second bump metal (250B) between the light-emitting diode (230) and the second electrode pad (242).

[0166] A circuit section (CP) may be disposed on the substrate (100) of the second island section (21). As described above, the substrate (100) of the second island section (21) may be connected to and integrally formed with the substrate (100) of the first island section (11) and the third island section (31).

[0167] A lower insulating layer (LI) may be disposed on the substrate (100). In one embodiment, the lower insulating layer (LI) may comprise an organic insulating material such as polyimide or an inorganic insulating material such as silicon oxide, silicon nitride, or silicon oxynitride. Additionally, the lower insulating layer (LI) may be a single layer or a multilayer. In one embodiment, the lower insulating layer (LI) may have a thickness corresponding to that of the inorganic insulating layers (201, 203, 205, 207). In some embodiments, the lower insulating layer (LI) may be omitted.

[0168] A first organic insulating layer (209) may be disposed on the lower insulating layer (LI), and a second organic insulating layer (211) and a third organic insulating layer (213) may be disposed sequentially on the first organic insulating layer (209). The first organic insulating layer (209), the second organic insulating layer (211), and the third organic insulating layer (213) may include an organic insulating material. The organic insulating material may include, for example, a general-purpose polymer such as polymethylmethacrylate (PMMA) or polystyrene (PS), a polymer derivative having a phenolic group, an acrylic polymer, an imide polymer, an aryl ether polymer, an amide polymer, a fluorine polymer, a p-xylene polymer, a vinyl alcohol polymer, and blends thereof.

[0169] The circuit portion (CP) may be disposed between insulating layers. For example, the circuit portion (CP) may include a plurality of circuit patterns, some of which may be disposed on the third organic insulating layer (213), other parts disposed between the third organic insulating layer (213) and the second organic insulating layer (211), other parts disposed between the second organic insulating layer (211) and the first organic insulating layer (209), and other parts disposed between the first organic insulating layer (209) and the lower insulating layer (LI). At least some of these plurality of circuit patterns may be connected to each other through contact holes.

[0170] Wiring (WL) may be arranged on the substrate (100) of the third island section (31). As described above, the substrate (100) of the third island section (31) may be connected to and formed integrally with the substrate (100) of the first island section (11) and the substrate (100) of the second island section (21).

[0171] A lower insulating layer (LI) may be disposed on the substrate (100). In one embodiment, the lower insulating layer (LI) may comprise an organic insulating material such as polyimide or an inorganic insulating material such as silicon oxide, silicon nitride, or silicon oxynitride. Additionally, the lower insulating layer (LI) may be a single layer or a multilayer. In one embodiment, the lower insulating layer (LI) may have a thickness corresponding to that of the inorganic insulating layers (201, 203, 205, 207). In some embodiments, the lower insulating layer (LI) may be omitted.

[0172] A first organic insulating layer (209) may be disposed on the lower insulating layer (LI), and a second organic insulating layer (211) and a third organic insulating layer (213) may be disposed sequentially on the first organic insulating layer (209). The first organic insulating layer (209), the second organic insulating layer (211), and the third organic insulating layer (213) may include an organic insulating material. The organic insulating material may include, for example, a general-purpose polymer such as polymethylmethacrylate (PMMA) or polystyrene (PS), a polymer derivative having a phenolic group, an acrylic polymer, an imide polymer, an aryl ether polymer, an amide polymer, a fluorine polymer, a p-xylene polymer, a vinyl alcohol polymer, and blends thereof.

[0173] A plurality of wirings (WL), for example, first to third wirings (WL1, WL2, WL3), may be disposed on different layers. For example, the first wiring (WL1) may be disposed between the third organic insulating layer (213) and the second organic insulating layer (211), the second wiring (WL2) may be disposed between the second organic insulating layer (211) and the first organic insulating layer (209), and the third wiring (WL3) may be disposed between the first organic insulating layer (209) and the lower insulating layer (LI). However, the present invention is not limited thereto, and in other embodiments, at least some of the first to third wirings (WL1, WL2, WL3) may be disposed on the same layer.

[0174] The support column (SC) may be placed on the upper surface (e.g., the upper surface) of the third island section (31). For example, the support column (SC) may be placed on the upper surface of the third organic insulating layer (213) of the third island section (31). In one embodiment, the height of the support column (SC) may be greater than the height of the light-emitting diode (230). That is, the height from the upper surface of the third organic insulating layer (213) to the upper surface of the support column (SC) may be greater than the height from the upper surface of the third organic insulating layer (213) to the upper surface of the light-emitting diode (230). Additionally, the height from the lower surface of the third island section (31) to the upper surface of the support column (SC) may be greater than the height from the lower surface of the first island section (11) to the upper surface of the light-emitting diode (230). In one embodiment, the support column (SC) may contain an organic material.

[0175] These support columns (SC) can be positioned so as not to overlap with the wiring (WL) arranged in the third island section (31) in one embodiment on the plan view. For example, the third island section (31) may be provided in a roughly rectangular shape, and the wiring (WL) may cross the third island section (31) by intersecting in a first direction (x direction) and a second direction (y direction) that intersects the first direction. The wiring (WL) may be arranged in a roughly '+' shape by intersecting in the central part of the third island section (31).

[0176] At this time, the support columns (SC) can be positioned so as not to overlap with the wiring (WL) on the plan view. For example, the support columns (SC) can be provided in multiple numbers, for example, four. The four support columns (SC) can be positioned adjacent to each of the four vertices of the third island section (31).

[0177] As described above, the light-emitting diode (230) can be pressed with a predetermined pressure after being placed in the first island section (11). For example, the light-emitting diode (230) can be connected to the electrode pad (240) by pressing the upper surface of the light-emitting diode (230) using a pressure plate. At this time, the pressure plate can cover not only the display area (DA) but also the non-display area (NDA) outside the display area (DA). Accordingly, when the light-emitting diode (230) is pressed, the pressure plate presses the upper part of the non-display area (NDA), for example, the second island section (21) and the third island section (31), thereby causing damage. In this case, damage may be caused to the circuit section (CP) of the second island section (21).

[0178] According to embodiments of the present invention, a support column (SC) can support a pressure plate in a non-display area (NDA). Since the third island section (31) is positioned adjacent to the second island section (21), the circuit section (CP) of the third island section (31) can be protected by the support column (SC) positioned in the second island section (21) supporting the pressure plate. Additionally, since the support column (SC) is positioned so as not to overlap with the wiring (WL) in a plan view, pressure damage caused by the wiring (WL) being positioned below the support column (SC) receiving the pressure of the pressure plate can be prevented.

[0179] Additionally, FIG. 8 illustrates a third island section (31) positioned between the first island section (11) and the second island section (21), but the present invention is not limited thereto. In other embodiments, a plurality of third island sections (31), for example, two third island sections (31), may be positioned between the first island section (11) and the second island section (21). In this case, the first island section (11), the third-1 island section, the third-2 island section, and the second island section (21) may be positioned in sequence. Furthermore, it goes without saying that a support column (SC) may be positioned in both the third-1 island section and the third-2 island section.

[0180] The protection column (TC) may be placed on the upper surface (e.g., the upper surface) of the second island section (21). For example, the protection column (TC) may be placed on the upper surface of the third organic insulating layer (213) of the second island section (21). In one embodiment, the height of the protection column (TC) may be smaller than the height of the support column (SC). That is, the height from the upper surface of the third organic insulating layer (213) to the upper surface of the protection column (TC) may be smaller than the height from the upper surface of the third organic insulating layer (213) to the upper surface of the support column (SC). Additionally, the height from the lower surface of the second island section (21) to the upper surface of the protection column (TC) may be smaller than the height from the lower surface of the third island section (31) to the upper surface of the support column (SC).

[0181] Additionally, in one embodiment, the height of the protection column (TC) may be smaller than the height of the light-emitting diode (230). That is, the height from the upper surface of the third organic insulating layer (213) to the upper surface of the protection column (TC) may be smaller than the height from the upper surface of the third organic insulating layer (213) to the upper surface of the light-emitting diode (230). Also, the height from the lower surface of the second island portion (21) to the upper surface of the protection column (TC) may be smaller than the height from the lower surface of the first island portion (11) to the upper surface of the light-emitting diode (230).

[0182] In one embodiment, the protection column (TC) may contain the same material as the support column (SC). Additionally, the protection column (TC) may be placed in the same layer as the support column (SC) and may be formed by the same process as the support column (SC).

[0183] These protection columns (TC) can be positioned so as not to overlap with the circuit section (CP) placed in the second island section (21) in one embodiment on the plan view. For example, the second island section (21) may be provided in a roughly rectangular shape. Multiple protection columns (TC) may be provided, and multiple protection columns (TC) may be arranged along the perimeter of the second island section (21).

[0184] According to embodiments of the present invention, the pressure plate can be supported in the non-display area (NDA) by the support column (SC) of the third island section (31) adjacent to the second island section (21). Accordingly, the second island section (21) may not have a support column (SC) and may have a protection column (TC) placed at a height lower than the support column (SC). The pressure of the pressure plate is supported by the support column (SC) in the non-display area (NDA), and the protection column (TC) may be a column intended to block the pressure plate from contacting the upper part of the second island section (21) rather than supporting the pressure plate. Additionally, since the protection column (TC) is placed so as not to overlap with the circuit section (CP) in the plan view, pressure damage caused by the circuit section (CP) being placed below the protection column (TC) can be prevented.

[0185] In one embodiment, the protective column (TC) may not be placed on the side proximate to the third island part (31) among the four sides of the second island part (21). Additionally, the size of the protective column (TC) placed on the side of the second island part (21) proximate to the third island part (31) may be larger than the size of the protective column (TC) placed on the other side of the second island part (21). Furthermore, according to one embodiment, the size of the protective column (TC) in the plan view may be smaller than the size of the support column (SC).

[0186] The pressure plate may have a greater pressure applied along the direction from the display area (DA) to the non-display area (NDA) in the second island section (21), that is, from the first island section (21) to the second island section (21). The protection column (TC) can protect the circuit section (CP) of the second island section (21) more effectively as it is positioned in a larger size in the area where the pressure of the pressure plate is greater.

[0187] FIGS. 9 and 10 are cross-sectional views schematically illustrating a display device according to embodiments of the present invention, which may correspond to a cross-section taken along line VIII-VIII' of FIG. 7. Since the display device according to the present embodiment is similar to the display device described above, the following description will focus only on the differences.

[0188] Referring to FIG. 9, in one embodiment, a support column (SC) may also be placed in the second island section (21). The support column (SC) may be placed on the upper part of the second island section (21). For example, the support column (SC) may be placed on the upper part of the third organic insulating layer (213) of the second island section (21). In this case, the support column (SC) may be placed so as not to overlap with the circuit section (CP) placed in the second island section (21) in the plan view. Additionally, the support column (SC) placed in the second island section (21) may have the same height as the support column (SC) placed in the third island section (31). In this case, the support column (SC) of the second island section (21) may support the pressure plate together with the support column (SC) of the third island section (31). At this time, it will be understood that the support column (SC) placed in the second island section (21) may contain the same material as the support column (SC) placed in the third island section (31), be placed in the same layer, and be formed by the same process.

[0189] Referring to FIG. 10, in one embodiment, a support member (SP) may be placed on the second island portion (21) to support the pressure plate. The support member (SP) may be placed on the upper part of the second island portion (21). For example, the support member (SP) may be placed on the upper part of the third organic insulating layer (213) of the second island portion (21). The support member (SP) may support the pressure plate similarly to a support column (SC). That is, the support member (SP) may have the same height as the support column (SC) placed on the third island portion (31). At this time, it will be understood that the support member (SP) may contain the same material as the support column (SC) placed on the third island portion (31), be placed on the same layer, and be formed by the same process.

[0190] In one embodiment, the support member (SP) may be positioned to cover at least a portion of the circuit member (CP). That is, the support member (SP) may be positioned to overlap at least a portion of the circuit member (CP) in a plan view. The support member (SP) is positioned to cover the upper surface of the second island member (21) and may have a tapered shape that narrows toward the top. As the support member (SP) is widely positioned on the upper surface of the second island member (21), it can support the pressure plate while distributing the pressure force across the entire second island member (21). Additionally, even though the support member (CP) overlaps with the circuit member (CP) in a plan view, the pressure force can be distributed to prevent damage to the circuit member (CP).

[0191] FIG. 11a is a plan view schematically illustrating a display device according to an embodiment of the present invention, and may be similar to FIG. 7. FIG. 11b is a cross-sectional view schematically illustrating a display device according to an embodiment of the present invention, and may be similar to FIG. 8. Since the display device according to the present embodiment is similar to the display devices described above, the following description will focus only on the differences.

[0192] Referring to FIGS. 11a and 11b, a first island section (11) may be placed in the display area (DA), and a second island section (21) and a third island section (31) may be placed in the non-display area (NDA). Specifically, a second island section (21) may be placed in the first sub-non-display area (SNDA1), and a third island section (31) may be placed in the second sub-non-display area (SNDA2) between the display area (DA) and the first sub-non-display area (SNDA1).

[0193] In this case, in one embodiment, a third sub-non-display area (SNDA3) may be defined on the outer side of the first sub-non-display area (SNDA1), for example, on the side opposite to the display area (DA). Additionally, a fourth sub-non-display area (SNDA4) may be defined between the first sub-non-display area (SNDA1) and the third sub-non-display area (SNDA3).

[0194] A fourth island section (41) may be placed in the third sub-non-display area (SNDA3). A fifth island section (51) may be placed in the fourth sub-non-display area (SNDA4). That is, the first island section (11), the third island section (31), the second island section (21), the fifth island section (51), and the fourth island section (41) may be placed in order in the direction from the display area (DA) toward the non-display area (NDA). Although not illustrated in the drawing, it will be understood that the island sections may be connected to each other by bridge sections.

[0195] The fourth island section (41) may have the same structure as the second island section (21). For example, the fourth island section (41) may have the same stacking structure as the second island section (21) and may be an island section where a circuit section (CP) is placed. A protection column (TC) may be placed in the fourth island section (41) in the same way as in the second island section (21).

[0196] The fifth island section (51) may have the same structure as the third island section (31). For example, the fifth island section (51) may have the same stacking structure as the third island section (31) and may be an island section where wiring (WL) is arranged. Support columns (SC) may be arranged in the fifth island section (51) in the same way as in the third island section (31).

[0197] That is, island sections where wiring (WL) is placed (e.g., the third island section (31) or the fifth island section (51)) and island sections where circuit sections (CP) are placed (e.g., the second island section (21) or the fourth island section (41)) can be arranged alternately. Accordingly, the pressure plate can be more stably supported by the support columns (SC) in the non-display area (NDA), and damage caused by contact with the circuit section (CP) can be prevented more effectively.

[0198] FIGS. 12a to 12c are schematic drawings illustrating a method for manufacturing a display device according to an embodiment of the present invention. The method for manufacturing a display device according to the present embodiment may be used to manufacture the aforementioned display device, but is not necessarily limited thereto.

[0199] Referring to FIG. 12a, a display board may be prepared. The display board may refer to a display device (1) that is in the process of manufacturing. As described above, the display board may include a first island section (11) placed in a display area (DA), a second island section (21) placed in a non-display area (NDA), and a third island section (31).

[0200] In the first island section (11), a substrate (100) and insulating layers on top of the substrate (100) may be laminated. An electrode pad (240) and a bump metal (250) on the electrode pad (240) may be disposed on top of the insulating layers. In the second island section (21), a substrate (100) and insulating layers on top of the substrate (100) may be laminated. A protection column (TC) may be disposed on top of the insulating layers. In the third island section (31), a substrate (100) and insulating layers on top of the substrate (100) may be laminated. A support column (SC) may be disposed on top of the insulating layers.

[0201] Referring to FIG. 12b, a light-emitting diode (230) can be connected to the first island portion (11). At this time, to ensure a secure connection of the light-emitting diode (230), the upper surface of the display board can be pressed with a pressure plate (PT). At this time, the pressure plate (PT) can cover the entire upper surface of the display board. For example, the pressure plate (PT) can cover not only the display area (DA) but also the non-display area (NDA).

[0202] Referring to FIG. 12c, the pressure plate (PT) can press the light-emitting diode (230) against the upper surface of the first island section (11). At this time, due to the pressure, a portion of the pressure plate (PT) corresponding to the non-display area (NDA) can press the second island section (21) and the third island section (31) placed in the non-display area (NDA). According to embodiments of the present invention, a support column (SC) placed in the third island section (31) supports the pressure plate (PT) to prevent the pressure plate (PT) from contacting and damaging the upper surfaces of the second island section (21) and the third island section (31). Additionally, the protection column (TC) of the second island section (21) can be positioned to prevent damage to the circuit section (CP) of the second island section (21) when the pressure plate (PT) is pressed toward the second island section (21) even though it is supported by the support column (SC).

[0203] According to a method for manufacturing a display device according to one embodiment of the present invention, the pressure generated during the bonding process of the light-emitting diode (230) is distributed to support the non-display area (NDA), thereby preventing defects in the circuits or wiring located in the island portions.

[0204] The display device (1) according to the above-described embodiments can be used in various electronic devices capable of providing an image. Here, an electronic device refers to a device that uses electricity and has the function of providing a predetermined image.

[0205] FIG. 13a is a schematic perspective view of an electronic device (1000) including a display device according to one embodiment of the present invention, and FIG. 13b is a schematic block diagram of an electronic device (1000) including a display device (1) according to one embodiment of the present invention.

[0206] Referring to FIG. 13a, the electronic device (1000) can be freely deformed in three dimensions and can provide a three-dimensional image surface through the display area (DA). The statement that the electronic device (1000) can be freely deformed in three dimensions is distinguished from the operation of an electronic device having a rollable display device, such as when a part of the rolled-up display area is visible to the user, and then another part of the rolled-up display area is unfolded so that the entire display area is visible to the user (or when the entire unfolded display area is visible to the user, and then the display area is rolled up so that only a part of the display area is visible to the user). The electronic device (1000) according to embodiments of the present invention may exhibit a deformation such as the area of ​​the entire display area (DA) increasing or decreasing again as the electronic device (1000) is deformed in the x direction, y direction, and / or z direction.

[0207] Referring to FIG. 13b, the electronic device (1000) may include a processor (1100), memory (1200), input module (1300), display module (1400), power module (1500), built-in module (1600), and external module (1700). According to one embodiment, at least one of the above-described components may be omitted from the electronic device (1000), or one or more other components may be added.
