[0043] The inventive concept will now be described more fully below with reference to the accompanying drawings, in which various embodiments are shown. However, the inventive concept can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concept to those skilled in the art. The same reference numerals represent the same elements throughout.

[0044] Figure 1 is a plan view showing a display device according to an embodiment.

[0045] refer to Figure 1 , the display device DD can display an image in a fourth direction DR4 on a plane defined by the first direction DR1 and the third direction DR3. Here, the third direction DR3 may be a direction perpendicular to the first direction DR1. Meanwhile, in the present specification, the second direction DR2 may be a direction obliquely intersecting the first direction DR1. The front surface and the rear surface of each component included in the display device DD are defined by the fourth direction DR4. Meanwhile, the directions indicated by the first direction DR1, the second direction DR2, the third direction DR3, and the fourth direction DR4 may be defined as directions different from the above directions, and may be relative concepts. Meanwhile, the planar shape of the display device DD is not limited to a quadrilateral, and may be formed into a polygonal shape other than a quadrilateral, a circular shape, or an elliptical shape.

[0046] Display device DD (e.g. Figure 3 The substrate SUB) may include a main area MA and a sub area SBA.

[0047] The main area MA may include a display area DA displaying an image and a non-display area NDA located around the display area DA. For example, the non-display area NDA may surround the display area DA. The opening area DTA may be located in the display area DA.

[0048] The non-display area NDA may include a first non-display area NDA1, a second non-display area NDA2, and a third non-display area NDA3. The first non-display area NDA1 may surround the display area DA, the second non-display area NDA2 may surround the first non-display area NDA1, and the third non-display area NDA3 may surround the second non-display area NDA2.

[0049] In other words, the first non-display area NDA1 may be disposed between the display area DA and the second non-display area NDA2, and the second non-display area NDA2 may be disposed between the first non-display area NDA1 and the third non-display area NDA3. That is, the first non-display area NDA1 may be disposed inside the second non-display area NDA2, and the third non-display area NDA3 may be disposed outside the second non-display area NDA2.

[0050] The second non-display area NDA2 may be provided with a protruding member ( Figure 8 The protruding member PM may prevent the encapsulation layer ( Figure 3 Organic encapsulation layer ( Figure 3 EOL in the display) overflows to the third non-display area NDA3.

[0051] The sub-region SBA may protrude from one side of the main region MA in a direction opposite to the first direction DR1. In an embodiment, the length of the sub-region SBA in the third direction DR3 may be shorter than the length of the main region MA in the third direction DR3. However, the inventive concept is not necessarily limited thereto. The sub-region SBA may be curved, and a portion of the sub-region SBA may be disposed on the rear surface of the display device DD. In this case, a portion of the sub-region SBA may overlap with the main region MA in the fourth direction DR4.

[0052] The sub-area SBA may include a first area A1, a second area A2, and a bending area BA.

[0053] The first area A1 may protrude from one side of the main area MA in a direction opposite to the first direction DR1. One side of the first area A1 may contact the non-display area NDA of the main area MA, and the other side of the first area A1 may contact the bending area BA.

[0054] The second area A2 may be an area where the pad portion PD and the data driver DDV are disposed. The pad portion PD may be electrically connected to an external device (eg, a printed circuit board). One side of the second area A2 may contact the bending area BA.

[0055] The bending area BA may be bent. When the bending area BA is bent, the second area A2 may be disposed below the first area A1 and below the main area MA. The bending area BA may be disposed between the first area A1 and the second area A2. One side of the bending area BA may contact the first area A1, and the other side of the bending area BA may contact the second area A2.

[0056] The display device DD may include pixels PX. The pixels PX may be disposed in the display area DA. Each of the pixels PX may include a light emitting element and a transistor connected to the light emitting element. In an embodiment, each of the pixels PX may emit red light, green light, blue light, or white light.

[0057] The display device DD may include a plurality of lines. The lines may include data lines DL extending in a first direction DR1 and scan lines SL extending in a third direction DR3.

[0058] The data driver DDV may be disposed in the sub-area SBA. Specifically, the data driver DDV may be disposed in the second area A2. More specifically, the data driver DDV may be disposed between the display area DA and the pad portion PD. The data driver DDV may generate a data voltage. The data voltage may be transmitted to the pixel PX through the data line DL.

[0059] The data line DL may be electrically connected to the data driver DDV through the transmission line portion TLP. That is, the data voltage generated by the data driver DDV may be transmitted to the data line DL through the transmission line portion TLP. In an embodiment, the transmission line portion TLP may overlap the non-display area NDA and may be connected to the data line DL. In other words, the transmission line portion TLP may be disposed between the data driver DDV and the display area DA. The transmission line portion TLP may extend obliquely toward the second direction DR2. This will be referred to later. Figures 5 to 7 The transmission line part TLP is described in detail.

[0060] The scan driver SDV may be disposed in the non-display area NDA. The scan driver SDV may be located on the left and right sides of the display area DA. For example, the scan driver SDV may be disposed in the first non-display area NDA1. However, the inventive concept is not necessarily limited thereto, and the scan driver SDV may be disposed in the third non-display area NDA3. The scan driver SDV may generate a scan signal. The scan signal may be transmitted to the pixel PX through the scan line SL.

[0061] Meanwhile, the lines may further include a power voltage line (not shown) for transmitting a power voltage to the pixels PX.

[0062] Figure 2 It is shown Figure 1 Magnified view of the enlarged area A.

[0063] refer to Figure 1 and Figure 2 As described above, the display device DD may include data lines DL, scan lines SL, and pixels PX. The pixels PX may be connected to the data lines DL and the scan lines SL.

[0064] Display device DD (e.g. Figure 3 The substrate SUB) may further include an opening area DTA and a peripheral area LA, and at least one electronic module (such as a camera, a speaker, or a sensor for detecting light or heat) is exposed through the opening area DTA. The opening area DTA may be surrounded by the peripheral area LA, and the peripheral area LA may be surrounded by the display area DA. That is, the peripheral area LA may be an area surrounding the outside of the opening area DTA, and may be an intermediate area between the display area DA and the opening area DTA. The peripheral area LA may include a first peripheral area LA1 and a second peripheral area LA2.

[0065] The first peripheral area LA1 may include an area where laser is irradiated to remove some layers. In addition, the first dam D1 and the second dam D2 may be provided in the first peripheral area LA1. The first peripheral area LA1 may be an area to prevent damage to elements and lines located in the display area DA even when a process of cutting off the opening area DTA is performed after laser irradiation.

[0066] The second peripheral area LA2 may be an area in which a portion (RDL, hereinafter referred to as a bypass portion) of the data line DL extending along the periphery of the opening area DTA is provided. Therefore, even if the data line DL cannot have a line shape due to the opening area DTA, the pixels PX located above and below the opening area DTA may be connected to one data line DL due to the bypass portion RDL extending along the periphery of the opening area DTA.

[0067] The first peripheral area LA1 may be located closer to the opening area DTA than the second peripheral area LA2, and the second peripheral area LA2 may be located closer to the display area DA than the first peripheral area LA1.

[0068] At the same time, the scan line SL of the pixel PX located on the left side of the opening area DTA can be electrically connected only to the scan driver SDV located on the left side of the display area DA, and the scan line SL of the pixel PX located on the right side of the opening area DTA can be electrically connected only to the scan driver SDV located on the right side of the display area DA. That is, the scan line SL connected to the pixel PX located on the left side of the opening area DTA and the scan line SL connected to the pixel PX located on the right side of the opening area DTA can be disconnected at the opening area DTA. However, the inventive concept is not necessarily limited thereto, and in another example, the scan lines SL located on the left and right sides of the opening area DTA can be connected to each other in a bypass portion RDL in which a bypass scan line is provided, the bypass scan line connecting the scan line SL located on the left side of the opening area DTA and the scan line SL located on the right side of the opening area DTA.

[0101] The second peripheral area LA2 may be an area where the bypass portion RDL is disposed. The bypass portion RDL may be a portion of the data line DL extending along the periphery of the opening area DTA. In an embodiment, the bypass portion RDL may be included in the first data conductive layer SD1 and may be disposed on the third inorganic insulating layer IL3.

[0102] The buffer layer BF, the first inorganic insulating layer IL1, the second inorganic insulating layer IL2, and the third inorganic insulating layer IL3 may be disposed in the peripheral area LA on the substrate SUB. That is, the buffer layer BF, the first inorganic insulating layer IL1, the second inorganic insulating layer IL2, and the third inorganic insulating layer IL3 may continuously extend from the display area DA to the peripheral area LA.

[0103] In the second peripheral area LA2, the bypass portion RDL may be disposed on the third inorganic insulating layer IL3, and the first organic insulating layer IL4, the second organic insulating layer IL5, the pixel defining layer IL6, the spacer IL7, the functional layer FL, the second electrode E2, and the encapsulation layer ENC may be continuously disposed on the bypass portion RDL. In addition, an outer coating YOC as an additional insulating layer, a touch insulating layer YILD, and a planarization layer YPVX may be further disposed on the encapsulation layer ENC.

[0104] Meanwhile, in the first peripheral area LA1 , a portion where the dams D1 and D2 are located and the first, second, and third disconnected regions R1 , R2 , and R3 may have different layered structures.

[0105] First, the layered structure of the first disconnected region R1 , the second disconnected region R2 , and the third disconnected region R3 will be described as follows.

[0106] In the first disconnection region R1, the second disconnection region R2, and the third disconnection region R3, the substrate SUB, the buffer layer BF, the first inorganic insulating layer IL1, the second inorganic insulating layer IL2, the third inorganic insulating layer IL3, the first inorganic encapsulation layer EIL1, and the second inorganic encapsulation layer EIL2 may be stacked in sequence. However, the organic encapsulation layer EOL may be further disposed between the first inorganic encapsulation layer EIL1 and the second inorganic encapsulation layer EIL2 in the first disconnection region R1 positioned close to the display area DA. According to an embodiment, the organic encapsulation layer EOL may be further disposed to the second disconnection region R2 or the third disconnection region R3. However, since the organic encapsulation layer EOL of the encapsulation layer ENC is disposed not to be exposed to the outside to block moisture and oxygen, one end of the organic encapsulation layer EOL may be covered by the first inorganic encapsulation layer EIL1 and the second inorganic encapsulation layer EIL2 without being exposed to the outside.

[0107] That is, in the layered structure of the first disconnected region R1 , the second disconnected region R2 , and the third disconnected region R3 , the functional layer FL and the second electrode E2 may be disconnected.

[0108] The layered structure of a portion of the first peripheral area LA1 where the dams D1 and D2 are located is as follows.

[0109] In the first peripheral area LA1, the first dam D1 and the second dam D2 may be sequentially positioned. The first dam D1 and the second dam D2 may be disposed on the substrate SUB, the buffer layer BF, the first inorganic insulating layer IL1, the second inorganic insulating layer IL2, and the third inorganic insulating layer IL3.

[0110] The first dam D1 may include a 1-1st sub-dam D1-a, a 1-2nd sub-dam D1-b, and a 1-3rd sub-dam D1-c. The 1-1st sub-dam D1-a may be located on the same layer as the second organic insulating layer IL5 located in the display area DA, and may include the same material. The 1-1st sub-dam D1-a may be formed in the same process as the second organic insulating layer IL5 located in the display area DA. The 1-2nd sub-dam D1-b may be located on the same layer as the pixel defining layer IL6 located in the display area DA, and may include the same material. The 1-2nd sub-dam D1-b may be formed in the same process as the pixel defining layer IL6 located in the display area DA. The 1-3rd sub-dam D1-c may be located on the same layer as the spacer IL7 located in the display area DA, and may include the same material. The 1-3rd sub-dam D1-c may be formed in the same process as the spacer IL7 located in the display area DA.

[0111] The second dam D2 may include a 2-1st sub-dam D2-a, a 2-2nd sub-dam D2-b, a 2-3rd sub-dam D2-c, and a 2-4th sub-dam D2-d. The 2-1st sub-dam D2-a may be located on the same layer as the first organic insulating layer IL4 located in the display area DA, and may include the same material. The 2-1st sub-dam D2-a may be formed in the same process as the first organic insulating layer IL4 located in the display area DA. The 2-2nd sub-dam D2-b may be located on the same layer as the second organic insulating layer IL5 located in the display area DA, and may include the same material. The 2-2nd sub-dam D2-b may be formed in the same process as the second organic insulating layer IL5 located in the display area DA. The 2-3rd sub-dam D2-c may be located on the same layer as the pixel defining layer IL6 located in the display area DA, and may include the same material. The 2-3rd sub-dam D2-c may be formed in the same process as the pixel defining layer IL6 located in the display area DA. The 2-4th sub-dam D2 - d may be located on the same layer as the spacer IL7 located in the display area DA and may include the same material. The 2-4th sub-dam D2 - d may be formed in the same process as the spacer IL7 located in the display area DA.

[0112] At the same time, Figure 4 In the embodiment, the first dam D1 has a three-layer structure and the second dam D2 has a four-layer structure, but the present inventive concept is not necessarily limited thereto, and the number of layers of the first dam D1 and the second dam D2 may be variously changed. Figure 4 2 shows that two dams are provided in the peripheral area LA, but the present inventive concept is not necessarily limited thereto, and three or more dams may be provided in the peripheral area LA.

[0113] The 1-1 layer FL-1 may be disposed on the first dam D1. The 1-2 layer FL-2 may be disposed on the second dam D2. The 1-3 layer FL-3 may be disposed between the second dam D2 and the opening area DTA. The 1-1 layer FL-1, the 1-2 layer FL-2, and the 1-3 layer FL-3 may include the same material as the functional layer FL and may be formed in the same process.

[0114] On each of the 1-1 layer FL-1, the 1-2 layer FL-2, and the 1-3 layer FL-3, a 2-1 layer E2-1, a 2-2 layer E2-2, and a 2-3 layer E2-3 may be disposed. The 2-1 layer E2-1, the 2-2 layer E2-2, and the 2-3 layer E2-3 may include the same material as the second electrode E2 and may be formed in the same process.

[0115] The first inorganic encapsulation layer EIL1 extending from the display area DA may be disposed in the peripheral area LA. In addition, an end of the organic encapsulation layer EOL extending from the display area DA may be located in the peripheral area LA. The first dam D1 may control the diffusion of the organic material in the process of forming the organic encapsulation layer EOL. The organic encapsulation layer EOL may fill the space between the end of the display area DA and the first dam D1. The second inorganic encapsulation layer EIL2 overlapping the entire surface of the substrate SUB may be located on the organic encapsulation layer EOL.

[0116] The first inorganic encapsulation layer EIL1, the organic encapsulation layer EOL and the second inorganic encapsulation layer EIL2 may be sequentially disposed on the third inorganic insulating layer IL3 in the first disconnection region R1. In addition, the first inorganic encapsulation layer EIL1 and the second inorganic encapsulation layer EIL2 may be sequentially stacked on the third inorganic insulating layer IL3 in the second disconnection region R2 and the third disconnection region R3.

[0117] Meanwhile, the display device DD may further include an electronic module overlapping the opening area DTA. For example, the electronic module may be inserted into the opening area DTA. The electronic module may include various functional modules for operating the display device DD. For example, the electronic module may be a camera, a speaker, or a sensor for detecting light or heat.

[0118] The inner surface of the opening area DTA may be defined by the end of each of the substrate SUB, the buffer layer BF, the first inorganic insulating layer IL1, the second inorganic insulating layer IL2, the third inorganic insulating layer IL3, the 1-3 layer FL-3, the 2-3 layer E2-3, the first inorganic encapsulation layer EIL1, the second inorganic encapsulation layer EIL2, the overcoat layer YOC, the touch insulating layer YILD, and the planarization layer YPVX. However, the inventive concept is not necessarily limited thereto, and some of the above components may be omitted or other components may be added to define the inner surface of the opening area DTA.

[0119] At the same time, reference Figure 3 and Figure 4 The described cross-sectional structures of the display area DA, the peripheral area LA, and the opening area DTA are merely examples and may be variously changed according to embodiments.

[0120] Figure 5 It is shown Figure 1 Magnified view of the enlarged area B.

[0121] exist Figure 5, for convenience of description, a data line DL, a data pad line DPL, a data bending line DBL, a transmission line portion TLP, a first power line VSL, a first power pad line VSPL, a first power bending line VSBL, a second power line VDL, a second power pad line VDPL, and a second power bending line VDBL are shown.

[0122] refer to Figure 1 and Figure 5 , the data pad line DPL may be disposed in the second area A2. The data pad line DPL may be disposed between the data driver DDV and the data bending line DBL.

[0123] The data bending lines DBL may be disposed in the first area A1, the second area A2, and the bending area BA. The data bending lines DBL may be disposed between the transmission line portion TLP and the data pad line DPL. One end of each of the data bending lines DBL may be connected to the transmission line portion TLP through the second data contact hole DCT2, and the other end of each of the data bending lines DBL may be connected to the corresponding data pad line DPL through the first data contact hole DCT1.

One end of each of the transmission lines may be connected to the corresponding data line DL through a third data contact hole DCT3, and the other end of each of the transmission lines may be connected to the corresponding data bending line DBL through a second data contact hole DCT2. In an embodiment, the transmission line portion TLP may extend in the second direction DR2. That is, the transmission line portion TLP may extend in a direction obliquely intersecting with the first direction DR1.

[0125] At the same time, Figure 5 , for ease of description, the scan control lines connected to the scan driver SDV are omitted, but each of the scan control lines (not shown) may include a scan transfer line portion, a scan pad line, and a scan bending line, and the scan transfer line portion may be substantially the same as the transfer line portion TLP, the scan pad line may be substantially the same as the data pad line DPL, and the scan bending line may be substantially the same as the data bending line DBL.

[0126] The first power line VSL may be disposed in the non-display area NDA. The first power line VSL may overlap the second non-display area NDA2. In a plan view, the first power line VSL may overlap the transmission line portion TLP.

[0127] The first power bending line VSBL may be disposed in the first area A1, the second area A2, and the bending area BA. The first power bending line VSBL may be disposed between the first power line VSL and the first power pad line VSPL. The first power bending line VSBL may extend from the first power line VSL. The first power bending line VSBL may be formed integrally with the first power line VSL. That is, the first power bending line VSBL may be formed of the same material as the first power line VSL. Each of the first power bending lines VSBL may be connected to the corresponding first power pad line VSPL through a first line contact hole VSH.

[0128] The first power pad line VSPL may be disposed in the second area A2. The first power pad line VSPL may be disposed between the first power bending line VSBL and the pad portion PD. One end of each of the first power pad lines VSPL may be connected to the corresponding first power bending line VSBL through the first line contact hole VSH, and the other end of each of the first power pad lines VSPL may be connected to the pad portion PD.

[0132] Figure 6 It is shown Figure 5 An example of a magnified view of region C, and Figure 7 It is shown Figure 6 Magnified view of area D.

[0133] refer to Figures 5 to 7 , the third non-display area NDA3 may include a bank area BNKA and an inorganic layer area ILA.

[0134] The bank area BNKA may be spaced apart from the first non-display area NDA1 with the second non-display area NDA2 and the inorganic layer area ILA interposed therebetween. When manufacturing the display device DD, the bank area BNKA may be a bank ( Figure 8 The bank area BNKA may be disposed in the non-display area NDA in a direction opposite to the first direction DR1. Figure 8 Describe BNK in detail.

[0135] The inorganic layer area ILA may be disposed between the second non-display area NDA2 and the bank area BNKA. One side of the inorganic layer area ILA may contact the second non-display area NDA2, and the other side of the inorganic layer area ILA may contact the bank area BNKA. The inorganic layer area ILA may be an area in which at least one organic layer is removed and only an inorganic layer is disposed. For example, the inorganic layer area ILA may be an area in which the encapsulation layer ( Figure 3 The first inorganic encapsulation layer ( Figure 3 EIL1 in) and the second inorganic encapsulation layer ( Figure 3 The region directly in contact with EIL2 in the

[0136] Meanwhile, as described above, the second non-display area NDA2 may be provided with a protruding member ( Figure 8 PM) area.

[0137] A transmission line portion TLP for transmitting a data voltage to the data line DL may be disposed in the non-display area NDA. In detail, the transmission line portion TLP may overlap the inorganic layer area ILA. The transmission line portion TLP may include a first transmission line TL1 and a second transmission line TL2. Each of the first transmission line TL1 and the second transmission line TL2 may be connected to the data line DL.

[0138] The first transmission line TL1 may extend in the second direction DR2. The second transmission line TL2 may be arranged parallel to the first transmission line TL1. That is, the second transmission line TL2 may extend in the second direction DR2. In other words, the first transmission line TL1 and the second transmission line TL2 may extend in a direction obliquely intersecting the first direction DR1. The first transmission line TL1 and the second transmission line TL2 may be alternately arranged along a direction perpendicularly intersecting the second direction DR2.

[0139] The first transmission lines TL1 may be disposed on the same layer as each other. The second transmission lines TL2 may be disposed on the same layer as each other. The layer on which the first transmission lines TL1 are disposed may be different from the layer on which the second transmission lines TL2 are disposed. For example, the layer on which the second transmission lines TL2 are disposed may be located above the layer on which the first transmission lines TL1 are disposed. Fig.10 This is described in more detail.

[0140] For the second electrode ( Figure 3 The first power line VSL providing the first power voltage may be disposed in the non-display area NDA. The first power line VSL may include a first sub-power line SVSL1, a second sub-power line ( Figure 8 For example, the first power line VSL may include a plurality of first branches BRP1. Since the second sub-power line SVSL2 is disposed below the first sub-power line SVSL1, Figure 6 The illustration of the second sub power line SVSL2 is omitted.

[0141] The first sub power line SVSL1 may extend in the first direction DR1. For example, the first sub power line SVSL1 may be disposed in the first non-display area NDA1, the second non-display area NDA2, the inorganic layer area ILA, and the bank area BNKA. The first sub power line SVSL1 may be connected to the second sub power line SVSL2 through the first power contact hole VSCT. Therefore, the resistance of the first power line VSL may be reduced.

[0142] In the inorganic layer area ILA, due to the inclination of the side surface of the first sub-power line SVSL1, the first sub-power line SVSL1 may not be properly covered by the first inorganic encapsulation layer EIL1 and the second inorganic encapsulation layer EIL2. That is, in the inorganic layer area ILA, due to the inclination of the side surface of the first sub-power line SVSL1, a gap may appear in the first inorganic encapsulation layer EIL1 and the second inorganic encapsulation layer EIL2. The gap may be a permeable passage for external air or moisture.

[0143] The first branch BRP1 may protrude from one side of the first sub power line SVSL1. The first branch BRP1 may be disposed in the inorganic layer area ILA. In addition, the first branch BRP1 may be disposed in the first non-display area NDA1, the second non-display area NDA2, and the bank area BNKA, but the inventive concept is not necessarily limited thereto. The first branch BRP1 may be omitted in at least one of the first non-display area NDA1, the second non-display area NDA2, and the bank area BNKA.

[0144] In the inorganic layer area ILA, a portion with poor step coverage may be formed along the side surface of the first sub-power line SVSL1. Therefore, a penetration path for external air or moisture through the portion with poor step coverage in the inorganic layer area ILA may be formed along the side surface of the first sub-power line SVSL1. Since the first power line VSL includes the first branch BRP1, the length of the side surface of the first power line VSL may include the length of the periphery of the first branch BRP1. Therefore, the length of the side surface of the first power line VSL when the first branch BRP1 is included may be longer than the length of the side surface of the first power line VSL when the first branch BRP1 is not included. Therefore, the moisture penetration path may be relatively long. Therefore, even if a portion with poor step coverage is formed along the side surface of the first sub-power line SVSL1 in the inorganic layer area ILA, the penetration of external air or moisture into the display area DA may be delayed or prevented.

[0145] Meanwhile, the first branch BRP1 may have a first edge ES1 and a second edge ES2 that completely overlap the transmission line portion TLP in a plan view. In other words, the first edge ES1 and the second edge ES2 of the first branch BRP1 may not overlap the space between the first transmission line TL1 and the second transmission line TL2 in a plan view. In this case, the first edge ES1 and the second edge ES2 may be edges having one end in contact with the first sub power line SVSL1.

[0146] In an embodiment, in a plan view, the first edge ES1 may completely overlap one of the second transmission lines TL2, and in a plan view, the second edge ES2 may completely overlap another of the second transmission lines TL2. Therefore, in a plan view, the first branch BRP1 may overlap a portion of at least one of the first transmission lines TL1. For example, Figure 6 and Figure 7 As shown in , one of the first transmission lines TL1 may be disposed between the second transmission line TL2 having the first edge ES1 disposed thereon in plan view and the second transmission line TL3 having the second edge ES2 disposed thereon in plan view. Therefore, in plan view, the first branch BRP1 may overlap a portion of one of the first transmission lines TL1.

[0147] However, the inventive concept is not necessarily limited thereto, and the number of first transmission lines TL1 disposed between the second transmission line TL2 overlapping the first edge ES1 in plan view and the second transmission line TL2 overlapping the second edge ES2 in plan view may be variously changed according to the area (or size) of the first branch BRP1. For example, two of the first transmission lines TL1 may be disposed between the second transmission line TL2 overlapping the first edge ES1 in plan view and the second transmission line TL2 overlapping the second edge ES2 in plan view. Therefore, in plan view, the first branch BRP1 may overlap a portion of each of the two first transmission lines TL1.

[0148] In addition, Figure 6 , the areas of the first branches BRP1 included in the first power line VSL are all shown to be the same, but the inventive concept is not necessarily limited thereto. That is, the number of first transfer lines TL1 overlapped with the first branches BRP1 may be different for each of the first branches BRP1. For example, in a plan view, at least one of the first branches BRP1 may overlap a portion of one of the first transfer lines TL1, and in a plan view, the other of the first branches BRP1 may overlap a portion of each of two of the first transfer lines TL1.

[0149] Since the transmission line overlapping the first edge ES1 in plan view and the transmission line overlapping the second edge ES2 in plan view are disposed on the same layer, the step difference due to the first branch BRP1 may be reduced or prevented.

[0150] The first branch BRP1 may protrude from one side of the first sub power line SVSL1 so that the first edge ES1 and the second edge ES2 are parallel to the first transmission line TL1 and the second transmission line TL2. For example, the first edge ES1 and the second edge ES2 may extend from one side of the first sub power line SVSL1 in a direction opposite to the second direction DR2. In an embodiment, the first edge ES1 and the second edge ES2 may have a straight line shape extending parallel to the first transmission line TL1 and the second transmission line TL2.

[0151] When the first edge ES1 and the second edge ES2 of the first branch BRP1 overlap with the space between the first transfer line TL1 and the second transfer line TL2, the first power line VSL (e.g., the first branch BRP1) may be easily damaged by external pressure, etc. On the other hand, according to an embodiment, in a plan view, the first edge ES1 and the second edge ES2 of the first branch BRP1 may completely overlap with the transfer line portion TLP. In addition, the first edge ES1 and the second edge ES2 of the first branch BRP1 may extend parallel to the transfer line portion TLP. Therefore, damage to the first power line VSL due to external pressure, etc. may be reduced or prevented. Therefore, the durability of the display device DD may be improved.

[0152] Specifically, when the display device DD includes Figure 4 When the first disconnection area R1, the second disconnection area R2 and the third disconnection area R3 are formed, the process of forming a sacrificial layer may be accompanied. Therefore, in the process of forming the sacrificial layer, additional damage to the first power line VSL may be caused. Therefore, in the inorganic layer area ILA, it may be easier for external air or moisture to penetrate through the portion with poor step coverage. According to an embodiment, the first power line VSL may have a first branch BRP1 protruding from one side of the first sub-power line SVSL1. In addition, in a plan view, the first edge ES1 and the second edge ES2 of the first branch BRP1 may completely overlap with the transmission line portion TLP. In addition, the first edge ES1 and the second edge ES2 of the first branch BRP1 may extend parallel to the transmission line portion TLP. Therefore, the moisture penetration path is increased, and damage to the first power line VSL due to external pressure, etc. can be reduced or prevented. Therefore, even after the process of forming the sacrificial layer, the penetration of external air or moisture through the gap in the inorganic layer area ILA can be reduced or prevented. Therefore, the durability of the display device DD can be improved.

[0153] The second power line VDL may be spaced apart from the first power line VSL. The second power line VDL may provide a second power voltage having a higher potential than the first power voltage to the display area DA. The second power line VDL may include a third sub-power line SVDL1, a fourth sub-power line SVDL2, a fifth sub-power line SVDL3, and a second branch BRP2. For example, the second power line VDL may include a plurality of second branches BRP2.

[0154] The third sub-power line SVDL1, the fourth sub-power line SVDL2, and the fifth sub-power line SVDL3 may extend in the first direction DR1. For example, the third sub-power line SVDL1 may be disposed in the second non-display area NDA2, the inorganic layer area ILA, and the bank area BNKA. The fourth sub-power line SVDL2 may be disposed in the first non-display area NDA1 and the second non-display area NDA2. The third sub-power line SVDL1 may be connected to the fourth sub-power line SVDL2 through the second power contact hole VDCT1. The fifth sub-power line SVDL3 may be disposed in the first non-display area NDA1. The fifth sub-power line SVDL3 may be connected to the fourth sub-power line SVDL2 through the third power contact hole VDCT2.

[0155] In the inorganic layer area ILA, due to the inclination of the side surface of the third sub-power line SVDL1, the third sub-power line SVDL1 may not be properly covered by the first inorganic encapsulation layer EIL1 and the second inorganic encapsulation layer EIL2. That is, in the inorganic layer area ILA, due to the inclination of the side surface of the third sub-power line SVDL1, a portion with poor step coverage may appear in the first inorganic encapsulation layer EIL1 and the second inorganic encapsulation layer EIL2. The portion with poor step coverage may be a permeable passage for external air or moisture.

[0156] The second branch BRP2 may protrude from one side of the third sub-power line SVDL1. The second branch BRP2 may be disposed in the inorganic layer area ILA. In addition, the second branch BRP2 may not be disposed in the first non-display area NDA1, the second non-display area NDA2, and the bank area BNKA, but the inventive concept is not necessarily limited thereto. The first branch BRP1 may be additionally disposed in at least one of the first non-display area NDA1, the second non-display area NDA2, and the bank area BNKA.

[0157] In the inorganic layer area ILA, a portion with poor step coverage may be formed along the side surface of the third sub-power line SVDL1. Therefore, a moisture penetration path for external air or moisture to pass through the portion with poor step coverage in the inorganic layer area ILA may be formed along the side surface of the third sub-power line SVDL1. Since the third sub-power line SVDL1 includes the second branch BRP2, the length of the side surface of the second power line VDL may include the length of the periphery of the second branch BRP2. Therefore, the length of the side surface of the second power line VDL when the second branch BRP2 is included may be longer than the length of the side surface of the second power line VDL when the second branch BRP2 is not included. Therefore, the moisture penetration path may be relatively long. Therefore, even if a portion with poor step coverage is formed along the side surface of the third sub-power line SVDL1 in the inorganic layer area ILA, the penetration of external air or moisture may be delayed or prevented.

[0158] At the same time, the second branch BRP2 may have a third edge ES3 and a fourth edge ES4 that completely overlap the transmission line portion TLP in a plan view. In other words, in a plan view, the third edge ES3 and the fourth edge ES4 of the second branch BRP2 may not overlap the space between the first transmission line TL1 and the second transmission line TL2. In this case, the third edge ES3 and the fourth edge ES4 may be edges having one end in contact with the third sub-power line SVDL1.

[0159] In addition, the third edge ES3 and the fourth edge ES4 of the second branch BRP2 may extend from one side of the third sub-power line SVDL1 in the second direction DR2. That is, the second branch BRP2 may protrude from one side of the third sub-power line SVDL1 so that the third edge ES3 and the fourth edge ES4 are parallel to the first and second transfer lines TL1 and TL2.

[0160] Meanwhile, since the arrangement relationship between the second branch BRP2 and the transmission line portion TLP is substantially the same as the arrangement relationship between the first branch BRP1 and the transmission line portion TLP, a detailed description thereof will be omitted.

[0161] According to an embodiment, in a plan view, the third edge ES3 and the fourth edge ES4 of the second branch BRP2 may completely overlap with the transmission line portion TLP. In addition, the third edge ES3 and the fourth edge ES4 of the second branch BRP2 may extend parallel to the transmission line portion TLP. Therefore, damage to the second power line VDL due to external pressure or the like may be reduced or prevented. Therefore, the durability of the display device DD may be improved.

[0162] Figure 8 It is along Figure 6 A cross-sectional view taken along line II'.

[0163] refer to Figure 8 , the first power line VSL may include a first sub-power line SVSL1 and a second sub-power line SVSL2. The protruding member PM may include a first sub-protruding member SPM1, a second sub-protruding member SPM2, a third sub-protruding member SPM3, and a fourth sub-protruding member SPM4. The protruding member PM may be disposed in the second non-display area NDA2. Figure 8It is shown that one protruding member PM is disposed in the second non-display area NDA2, but the inventive concept is not necessarily limited thereto. Two or more protruding members PM may be disposed in the second non-display area NDA2. The valley structure VLS may be a structure for forming a valley VAL between the valley structure VLS and the first organic insulating layer IL4, and may be disposed in the first non-display area NDA1.

That is, the fourth sub power line SVDL2 may be formed by connecting to the source electrode ( Figure 3 SE), drain electrode ( Figure 3 The source electrode SE, the drain electrode DE, the fourth sub-power line SVDL2 and the second sub-power line SVSL2 may be formed of the same material and disposed on the same layer.

[0179] In addition, since the protruding member PM, the valley structure VLS, the bank BNK, the encapsulation layer ENC and the touch insulating layer YILD can be Figure 8 Those described are substantially the same. Therefore, redundant descriptions are omitted.

[0180] Fig.10 It is along Figure 7 A cross-sectional view taken along line III-III'.

[0181] refer to Fig.10 , the first transmission line TL1 may be a first gate conductive layer ( Figure 3 That is, the first transfer line TL1 may be formed by connecting to the gate electrode ( Figure 3 GE) and the first capacitor electrode ( Figure 3 In other words, the gate electrode GE, the first capacitor electrode CSE1, and the first transfer line TL1 may be different parts of one conductive pattern.

[0182] The second transfer line TL2 may be a second gate conductive layer ( Figure 3 The second inorganic insulating layer IL2 is provided on the second transmission line TL2. That is, the layer on which the second transmission line TL2 is provided may be located above the layer on which the first transmission line TL1 is provided. For example, the second transmission line TL2 may be provided by connecting to the upper electrode ( Figure 3 AE) and the second capacitor electrode ( Figure 3 In other words, the upper electrode AE, the second capacitor electrode CSE2, and the second transfer line TL2 may be different parts of one conductive pattern.

[0183] As described above, the first transfer lines TL1 and the second transfer lines TL2 may be alternately arranged. For example, the second transfer lines TL2 may be disposed between the first transfer lines TL1, respectively.

[0184] Since the layer on which the first transfer line TL1 is disposed is different from the layer on which the second transfer line TL2 is disposed, the distance between the transfer lines forming the transfer line portion TLP can be reduced. Therefore, the area (or size) of the region in which the transfer line portion TLP is disposed can be reduced. Therefore, the non-display area NDA of the display device DD can be reduced.

[0185] In the inorganic layer area ILA, the first sub power line SVSL1 and the first branch BRP1 may be disposed on the third inorganic insulating layer IL3. That is, the layer on which the first sub power line SVSL1 and the first branch BRP1 are disposed may be located above the layer on which the transmission line portion TLP is disposed. The first sub power line SVSL1 and the first branch BRP1 may be integrally formed. That is, the first sub power line SVSL1 and the first branch BRP1 may be disposed on the same layer and formed of the same material.

[0186] As described above, in a plan view, the first edge ES1 and the second edge ES2 of the first branch BRP1 may completely overlap with the transfer line portion TLP. In other words, in a plan view, the first edge ES1 and the second edge ES2 of the first branch BRP1 may not overlap with the space between the first transfer line TL1 and the second transfer line TL2. For example, the first edge ES1 may completely overlap with one of the second transfer lines TL2 in a plan view, and the second edge ES2 may completely overlap with another of the second transfer lines TL2 in a plan view. Therefore, damage to the first power line VSL due to external pressure or the like may be reduced or prevented. Therefore, the durability of the display device DD may be improved.

[0187] Meanwhile, although not shown, the arrangement relationship between the second branch BRP2 and the transmission line portion TLP in the cross-sectional view may be similar to Fig.10The arrangement relationship between the first branch BRP1 and the transmission line portion TLP shown in FIG. 1 is substantially the same. Therefore, a detailed description is omitted.

[0188] According to an embodiment, the display device may include a transmission line portion and a power line disposed on the transmission line portion, and the power line may include a sub-power line and a branch protruding from one side of the sub-power line. Therefore, the length of the side surface of the power line may be longer than the length of the side surface of the power line not including the branch. Therefore, the moisture penetration path of the external air or moisture may be relatively long. Therefore, the penetration of the external air or moisture through the side surface of the power line may be delayed or prevented.

[0189] In addition, the branch may protrude from one side of the sub-power line so that the edge completely overlaps the transmission line portion in a plan view. In addition, the edge of the branch may extend parallel to the transmission line portion. Therefore, damage to the power line (e.g., branch) caused by external pressure, etc. may be reduced or prevented. Therefore, the durability of the display device may be improved.

[0190] Fig.11 It is shown Figure 5 An enlarged view of an example of area C. For example, Fig.11 Can correspond to Figure 6 A magnified view of .

[0191] refer to Fig.11 In an embodiment, the first edge ES1 of the first branch BRP1 may completely overlap one of the first transmission lines TL1 in a plan view, and the second edge ES2 may completely overlap another of the first transmission lines TL1 in a plan view. Therefore, the first branch BRP1 may overlap a portion of at least one of the second transmission lines TL2 in a plan view. For example, Fig.11 As shown in , one of the second transmission lines TL2 may be disposed between the first transmission line TL1 on which the first edge ES1 is disposed in plan view and the first transmission line TL1 on which the second edge ES2 is disposed in plan view. Therefore, in plan view, the first branch BRP1 may overlap a portion of one of the second transmission lines TL2.

[0192] However, the inventive concept is not necessarily limited thereto, and the number of second transmission lines TL2 disposed between the first transmission line TL1 at which the first edge ES1 is disposed in the plan view and the first transmission line TL1 at which the second edge ES2 is disposed in the plan view may be variously changed according to the area (or size) of the first branch BRP1. For example, two of the second transmission lines TL2 may be disposed between the first transmission line TL1 at which the first edge ES1 is disposed in the plan view and the first transmission line TL1 at which the second edge ES2 is disposed in the plan view. Therefore, in the plan view, the first branch BRP1 may overlap a portion of each of the two second transmission lines TL2.

[0193] Meanwhile, in the plan view, the third edge ES3 and the fourth edge ES4 of the second branch BRP2 may also completely overlap with the first transmission line TL1. For example, in the plan view, the third edge ES3 may completely overlap with one of the first transmission lines TL1, and in the plan view, the fourth edge ES4 may overlap with another of the first transmission lines TL1.

[0194] Fig.12 It is shown Figure 5 An example of a magnified view of region C, and Fig.13 It is along Fig.12 For example, Fig.12 Can correspond to Figure 6 A magnified view of Fig.13 Can correspond to Fig.10 sectional view of .

[0195] refer to Fig.12 and Fig.13 In an embodiment, in a plan view, the first edge ES1 and the second edge ES2 may be aligned with the edge of the second transfer line TL2. For example, in a plan view, the first edge ES1 may be aligned with one edge of the corresponding second transfer line TL2, and in a plan view, the second edge ES2 may be aligned with one edge of the corresponding second transfer line TL2.

[0196] Meanwhile, although not shown, in another example, in a plan view, the first edge ES1 and the second edge ES2 may be aligned with the edge of the first transfer line TL1. For example, in a plan view, the first edge ES1 may be aligned with one edge of the corresponding first transfer line TL1, and in a plan view, the second edge ES2 may be aligned with one edge of the corresponding first transfer line TL1.

[0197] In addition, although not shown, the arrangement relationship between the second branch BRP2 and the transmission line portion TLP in the cross-sectional view may be similar to Fig.13The arrangement relationship between the first branch BRP1 and the transmission line portion TLP shown in FIG. 1 is substantially the same. Therefore, a detailed description is omitted.

[0198] Fig.14 It is shown Figure 5 An enlarged view of an example of area C. For example, Fig.14 Can correspond to Figure 6 A magnified view of .

[0199] refer to Fig.14 , the transmission line portion TLP may further include a third transmission line TL3. The third transmission line TL3 may be disposed on the same layer as each other. The layer on which the third transmission line TL3 is disposed may be different from the layer on which the first transmission line TL1 is disposed and the layer on which the second transmission line TL2 is disposed. For example, the third transmission line TL3 may be disposed on the first inorganic insulating layer ( Fig.10 IL1 in the figure), and an additional sub-insulating layer may be disposed on the first inorganic insulating layer IL1 and the third transfer line TL3, and the first transfer line TL1 may be disposed on the additional sub-insulating layer.

[0200] However, the present inventive concept is not necessarily limited thereto, and in another example, the layer on which the third transmission line TL3 is disposed may be located above the layer on which the first transmission line TL1 is disposed and the layer on which the second transmission line TL2 is disposed. In another example, the layer on which the third transmission line TL3 is disposed may be located between the layer on which the first transmission line TL1 is disposed and the layer on which the second transmission line TL2 is disposed.

[0201] The third transmission line TL3 may be arranged parallel to the first transmission line TL1 and the second transmission line TL2. That is, the third transmission line TL3 may extend in the second direction DR2. In other words, the third transmission line TL3 may extend in a direction obliquely intersecting the first direction DR1. The first transmission line TL1, the second transmission line TL2, and the third transmission line TL3 may be arranged alternately.

[0202] In an embodiment, in a plan view, the first edge ES1 may completely overlap one of the third transmission lines TL3, and in a plan view, the second edge ES2 may completely overlap another of the third transmission lines TL3. Therefore, in a plan view, the first branch BRP1 may overlap a portion of at least one of the first transmission lines TL1 and a portion of at least one of the second transmission lines TL2. For example, Fig.14As shown in , one of the first transmission lines TL1 and one of the second transmission lines TL2 may be disposed between a third transmission line TL3 on which the first edge ES1 is disposed in the plan view and a third transmission line TL3 on which the second edge ES2 is disposed in the plan view. Therefore, in the plan view, the first branch BRP1 may overlap a portion of one of the first transmission lines TL1 and a portion of one of the second transmission lines TL2.

[0203] However, the present inventive concept is not necessarily limited thereto, and the number of first transmission lines TL1 and the number of second transmission lines TL2 arranged between the third transmission line TL3 having the first edge ES1 arranged thereon in the plan view and the third transmission line TL3 having the second edge ES2 arranged thereon in the plan view may be variously changed according to the area (or size) of the first branch BRP1.

[0204] Meanwhile, in the plan view, the third edge ES3 and the fourth edge ES4 of the second branch BRP2 may also completely overlap with the third transmission line TL3. For example, in the plan view, the third edge ES3 may completely overlap with one of the third transmission lines TL3, and in the plan view, the fourth edge ES4 may completely overlap with another of the third transmission lines TL3.

[0205] The inventive concept should not be interpreted as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the inventive concept to those skilled in the art.

[0206] While the inventive concept has been particularly shown and described with reference to embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit or scope of the inventive concept as defined by the appended claims.
