[0094] When describing the embodiment, the circuit layer 120 and the light emitting element layer 130 are described separately, but the embodiment is not necessarily limited thereto. For example, the circuit layer 120 and the light emitting element layer 130 may be integrated.

[0095] The encapsulation layer 140 may be disposed on the light emitting element layer 130 to encapsulate pixels disposed in the active area AA of the circuit layer 120 and the light emitting element layer 130. The encapsulation layer 140 may extend into the non-active area NA to contact the circuit layer 120. In an embodiment, the encapsulation layer 140 may have a multi-layer structure including at least two inorganic encapsulation films stacked on each other and at least one organic encapsulation film disposed between the inorganic encapsulation films.

[0096] The sensor layer 150 may be disposed on the encapsulation layer 140 and at least in the main area MA. In an embodiment, the sensor layer 150 may be a touch sensor layer and may include sensor electrodes for detecting touch input (direct touch, proximity, etc.) from a person or an object. In this case, the sensor layer 150 may constitute or form a touch sensor. The sensor layer 150 may include sensor electrodes disposed in the active area AA and wiring electrically connected to the sensor electrodes. In an embodiment, the wiring of the sensor layer 150 may extend from the main area MA to the sub-area SBA and be electrically connected to a pad disposed in the sub-area SBA.

[0097] The optical layer 160 may be disposed on the sensor layer 150 (or the encapsulation layer 140). In an embodiment, the optical layer 160 may include at least one of a polarization layer and a color filter layer, and may block external light reflected from the sensor layer 150, the encapsulation layer 140, the light emitting element layer 130, the circuit layer 120, and the interface therebetween. Therefore, it is possible to prevent the visibility of the image from being degraded due to the reflection of the external light.

[0098] The light blocker LBM may be disposed in the non-active area NA to surround the active area AA. For example, the light blocker LBM may be opened to expose at least the active area AA, and may be disposed on an edge area of ​​the sensor layer 150.

[0099] The light blocker LBM may be disposed or formed on one surface of the sensor layer 150 or the optical layer 160. For example, the light blocker LBM may be directly printed on one surface of the optical layer 160. Therefore, the printing accuracy of the light blocker LBM may be increased, and the light blocker LBM may be formed more clearly. However, the position and / or formation method of the light blocker LBM are not necessarily limited thereto. For example, the light blocker LBM may be arranged or disposed on one surface of a window or the like disposed above the display panel 100.

[0100] In an embodiment, the display panel 100 may be bent in the bending area BA. The bending area BA may be a part of the sub area SBA and may be spaced apart from the main area MA.

[0101] The substrate 110 and the circuit layer 120 may be bent in the bending area BA corresponding to a partial area of ​​the sub-area SBA. Therefore, a bezel area recognized as a non-active area NA by a user may be reduced or minimized.

[0102] In an embodiment, the display device 10 may further include a window disposed on the optical layer 160 to protect the display panel 100. The window may be attached to the optical layer 160 by a transparent adhesive member such as an optically clear adhesive (OCA) film or an optically clear resin (OCR). Alternatively, the window may be integrally manufactured with the display panel 100. The window may include an inorganic material such as glass or an organic material such as a plastic or polymer material.

[0103] In an embodiment, the display device 10 according to the embodiment may further include a touch driving circuit 400 for driving the sensor layer 150. In an embodiment, the touch driving circuit 400 may be implemented as an integrated circuit chip (IC) and may be mounted on the circuit board 300 bonded to the pad in the sub-area SBA to be electrically connected to the sensor layer 150. Alternatively, similar to the display driving circuit 200, the touch driving circuit 400 may be mounted on the substrate 110. For example, the touch driving circuit 400 may be mounted in the sub-area SBA.

[0104] The touch drive circuit 400 may apply a touch drive signal to at least some of the sensor electrodes provided in the sensor layer 150, and receive a touch sensing signal through at least some of the sensor electrodes. For example, when the sensor layer 150 includes drive electrodes and sensing electrodes constituting mutual capacitance sensor electrodes, the touch drive circuit 400 may apply a touch drive signal to the drive electrodes, receive a touch sensing signal of each of the touch nodes through the sensing electrodes, and detect a change in the charge of the mutual capacitance based on the touch sensing signal. Therefore, the touch drive circuit 400 (or a host processor that receives an electrical signal corresponding to the touch sensing signal from the touch drive circuit 400) may determine whether a user has touched or is close to the position of each of the touch nodes, etc., based on the touch sensing signal of each of the touch nodes.

[0105] Figure 4 is a plan view showing a display panel 100 according to an embodiment. Figure 4 The display panel 100 is shown in an unbent and unfolded state.

[0106] Apart from Figures 1 to 3 In addition, refer to Figure 4 , the display panel 100 may include a main area MA including an active area AA and a non-active area NA and a sub area SBA including a bank area BNKA, a driving circuit mounting area ICA, a pad area PA, and the like.

[0107] The active area AA may be an area in which pixels and sensor electrodes are disposed. Figure 6 The pixel PX and Figure 5 or Figure 6 The sensor electrode TSE shown in FIG. 4 may be disposed in the active area AA.

[0108] The non-active area NA may be disposed close to the active area AA. For example, the non-active area NA may be a remaining area of ​​the main area MA except the active area AA, and may be an edge area of ​​the main area MA disposed outside the active area AA to surround the active area AA.

[0109] In an embodiment, the non-active area NA may include a first non-active area NA1, a second non-active area NA2, a third non-active area NA3, and a fourth non-active area NA4 disposed on different sides of the active area AA. For example, when viewed on a plane defined by the first direction DR1 and the second direction DR2, the non-active area NA may include a first non-active area NA1 disposed on the left side of the active area AA and extending in the first direction DR1, a second non-active area NA2 disposed on the lower side of the active area AA and extending in the second direction DR2, a third non-active area NA3 disposed on the right side of the active area AA and extending in the first direction DR1, and a fourth non-active area NA4 disposed above the active area AA and extending in the second direction DR2. The first non-active area NA1 and the third non-active area NA3 may be disposed on both sides of the active area AA in the second direction DR2. The second non-active area NA2 and the fourth non-active area NA4 may be disposed on both sides of the active area AA in the first direction DR1.

[0110] The pixels and sensor electrodes disposed in the active area AA may be electrically connected to the display drive circuit 200, the touch drive circuit 400, and / or the pad PD through wiring passing through the non-active area NA. For example, the wiring may be electrically connected to each of the pixels and each of the sensor electrodes inside the active area AA and / or at the boundary between the active area AA and the non-active area NA, and may pass through at least the second non-active area NA2 to extend to the sub-area SBA. At least some of the wiring may pass through the second non-active area NA2 from the first non-active area NA1 or the third non-active area NA3 to extend to the sub-area SBA.

[0111] In an embodiment, the light blocker LBM may be disposed in the non-active area NA of the display panel 100. For example, the light blocker LBM may be disposed on the sensor layer 150 in the non-active area NA of the display panel 100 to surround the active area AA. The light blocker LBM may have an opening OPN that exposes the active area AA and portions NA11, NA21, NA31, and NA41 of the non-active area NA disposed adjacent to the active area AA. For example, considering an error range, a viewing angle, and the like that may occur in a formation process and / or a setting process of the light blocker LBM, the light blocker LBM may be opened to an area equal to or larger than the active area AA so that the light blocker LBM does not cover the active area AA. The light blocker LBM may be disposed on the sensor layer 150 to cover the remaining portions NA12, NA22, NA32, and NA42 of the non-active area NA.

[0112] The sub-region SBA may include a bank region BNKA, a driving circuit mounting region ICA, and a pad region PA sequentially disposed on one side of the main region MA. Wiring (or portions of wiring), banks, and pads PD may be disposed in the sub-region SBA. At least some of the wirings may extend into the main region MA and be electrically connected to the pixel and / or sensor electrode.

[0113] The bank area BNKA may be an area in which a bank including at least one organic layer is disposed. In an embodiment, the bank area BNKA may include a bending area BA. For example, the bank area BNKA may include a bending area BA spaced apart from the main area MA and a first edge area BEA1 and a second edge area BEA2 disposed on both sides of the bending area BA in the first direction DR1. The bank may be disposed in the bending area BA and its peripheral area (e.g., the first edge area BEA1 and the second edge area BEA2 of the bank area BNKA) to cover a wiring passing through the bending area BA. In an embodiment, an inorganic insulating layer disposed on the display panel 100 may be removed in the bending area BA. The wiring passing through the bending area BA may be covered by a bank including at least one organic insulating layer. The display panel 100 may be bent in the bending area BA so that a portion of the sub-area SBA may be disposed behind the main area MA.

[0114] The driving circuit mounting area ICA may be an area in which the display driving circuit 200 is mounted. Input / output pads for connecting some of the wirings to the display driving circuit 200 may be provided in the driving circuit mounting area ICA. For example, in the driving circuit mounting area ICA, an input pad for connecting the display driving circuit 200 to a specific pad (e.g., a data input pad) of the pad area PA and an output pad for connecting the display driving circuit 200 to the pixel PX may be provided.

[0115] In some embodiments, the display driving circuit 200 may not be mounted on the display panel 100. In this case, the display panel 100 may not include the driving circuit mounting area ICA, and only the wiring may be disposed between the bank area BNKA and the pad area PA.

[0116] The pad area PA may be an area in which a pad PD for transmitting a power voltage and a driving signal required to drive the display panel 100 is disposed or arranged. The pad PD may include a first pad DP (e.g., a display pad) for displaying an image and a second pad TP (e.g., a touch pad) for sensing a touch input. For example, the first pad DP may include a power pad and a signal pad electrically connected to a pixel and / or an embedded circuit of the display panel 100 and the display driving circuit 200, and the second pad TP may include a signal pad electrically connected to a sensor electrode. The circuit board 300 may be disposed or combined on the pad PD.

[0121] In an embodiment, the sensor layer 150 may be integrally formed with the display panel 100.

In an embodiment, the second wiring TL2 may pass through the second non-active area NA2 and be electrically connected to the second pads TP, respectively.

[0136] In an embodiment, at least one wiring TL may pass through close to the active area AA and may pass through portions NA11, NA21, NA31, and NA41 of the non-active area NA overlapping the opening OPN of the light blocker LBM. In this case, at least one wiring TL may not be covered by the light blocker LBM and may be exposed to a visible area that can be recognized by a user.

Figure 5 In at least a portion of the area C including the peripheral area of ​​the portion NA21, at least one wiring TL may be exposed to a visible area according to an angle at which a user views the display panel 100, etc. In an embodiment, the wiring TL is formed to prevent, reduce or minimize the possibility of Figure 5 The pattern perspective phenomenon of the wiring TL exposed in the region C) of FIG. A detailed description thereof will be given later.

In an embodiment, the first wiring layer LTL of the second wiring portion STL22 may be arranged at the same layer as the first wiring layer LTL of the first wiring portion STL21 and the first wiring layer LTL of the third wiring portion STL23. For example, the first wiring layer LTL of the second wiring portion STL22 may be formed integrally with the first wiring layer LTL of the first wiring portion STL21 and the first wiring layer LTL of the third wiring portion STL23.

[0218] The third wiring portion STL23 of the second wiring TL2 may extend from one end of the second wiring portion STL22 in the first direction DR1 in the second non-active area NA2. For example, the third wiring portion STL23 may be a portion in which the second wiring TL2 extends in the first direction DR1 in the second non-active area NA2 and extends to the sub-area SBA.

[0219] In an embodiment, the third wiring portion STL23 of the second wiring TL2 may include at least two wiring layers. For example, the third wiring portion STL23 may include a first wiring layer LTL and a second wiring layer UTL stacked on each other with an insulating layer 152 interposed between the first wiring layer LTL and the second wiring layer UTL. The first wiring layer LTL and the second wiring layer UTL of the third wiring portion STL23 may be electrically connected to each other through a second contact portion CNT2' including at least one second contact hole CH2.

[0220] In the third wiring portion STL23 of the second wiring TL2, the first wiring layer LTL and the second wiring layer UTL may have substantially the same or similar widths and may be substantially and / or substantially overlapped. For example, the first wiring layer LTL and the second wiring layer UTL of the third wiring portion STL23 may completely overlap each other or may not overlap partially at an edge or the like due to a process error or the like that may occur within a predetermined tolerance error range.

[0221] Fig. 9 is a plan view showing a portion of the sensor layer 150 according to an embodiment. For example, Fig. 9 Shows Figure 8 A modified embodiment of the embodiment regarding the second wiring TL2.

[0222] Apart from Figures 1 to 8 In addition, refer to Fig. 9 The first wiring portion STL21 of the second wiring TL2 may include a single wiring layer. For example, the first wiring portion STL21 may include a single first wiring layer LTL similar to the second wiring portion STL22, and may be formed integrally with the second wiring portion STL22.

[0223] Fig.10 It shows that it can be set in Figure 8 A plan view of an embodiment of the wiring TL in the region F1 of FIG. Fig.10 Shows that it can be set in Figure 8 The first wiring TL1 in the region F1.

[0224] Fig.11 is shown corresponding to Fig.10 A cross-sectional view of an embodiment of a cross section taken along line G-G'. Fig.12 is shown corresponding to Fig.10 A cross-sectional view of an embodiment of a cross-section taken along line HH'.

[0225] Apart from Figures 1 to 9 In addition, refer to Figures 10 to 12 , a plurality of wirings TL including at least two first wirings TL1 may pass through a portion NA21 of the second non-active area NA2 that is not covered by the light blocker LBM. One of the plurality of wirings TL may include each of the first wiring portions STL11 including at least two wiring layers (e.g., a first wiring layer LTL and a second wiring layer UTL), each of the second wiring portions STL12 including a single wiring layer (e.g., a first wiring layer LTL), and each of the third wiring portions STL13 including at least two wiring layers (e.g., a first wiring layer LTL and a second wiring layer UTL).

[0226] In an embodiment, each wiring layer may have a multilayer structure. For example, each of the first wiring layer LTL and the second wiring layer UTL may have a multilayer structure including first metal layers MT11 and MT21 including a first metal, second metal layers MT12 and MT22 disposed on the first metal layers MT11 and MT21 and including a second metal, and third metal layers MT13 and MT23 disposed on the second metal layers MT12 and MT22 and including a third metal. In an embodiment, the first metal and the third metal may have a light reflectivity that is smaller than that of the second metal, and may be made of the same material. For example, each of the first wiring layer LTL and the second wiring layer UTL may have a three-layer structure of titanium (Ti) / aluminum (Al) / titanium (Ti) in which first metal layers MT11 and MT21 including titanium (Ti), second metal layers MT12 and MT22 including aluminum (Al), and third metal layers MT13 and MT23 including titanium (Ti) are continuously stacked.

[0227] Fig.13 It shows that it can be set in Figure 8 A plan view of an embodiment of the wiring TL in the region F1 of FIG. Fig.13 Shows Fig.10 The embodiments of the present invention may be set in Figure 8 A modified example of the second wiring portion STL12 of the first wiring TL1 in the region F1 is shown in FIG.

[0228] Fig.14 is shown corresponding to Fig.13 A cross-sectional view of an embodiment of a cross section taken along line II'.

[0229] Apart from Figures 1 to 12 In addition, refer to Fig.13 and Fig.14 , a plurality of wirings TL passing through the second non-active area NA2 (for example, a first wiring TL1 passing through a portion NA21 of the second non-active area NA2 not covered by the light blocker LBM) may include a second wiring portion STL12 including a single second wiring layer UTL. In an embodiment, the second wiring portion STL12 of each of the first wirings TL1 may be provided at the same layer as the second wiring layer UTL of the first wiring portion STL11 and the second wiring layer UTL of the third wiring portion STL13 constituting the same first wiring TL1, and they may be formed integrally with each other.

[0230] In the embodiment, similarly to the first wiring TL1, Figure 5The second wiring TL2 disclosed in the specification may also include a second wiring portion STL22 including a single second wiring layer UTL. In addition, the second wiring portion STL22 of each of the second wirings TL2 may be arranged on the same layer as the second wiring layer UTL of the first wiring portion STL21 and the second wiring layer UTL of the third wiring portion STL23 constituting the same second wiring TL2, and they may be formed integrally with each other.

[0231] According to the above-described embodiment, the second wiring portions STL12 and STL22 of the wiring TL extending in the second direction DR2 may be formed as a single wiring layer in a visible region (e.g., a region corresponding to the opening OPN of the light blocker LBM and a region not covered by the light blocker LBM) that may be exposed to the user's field of vision and / or a region disposed close to the visible region (e.g., a region that may be visually recognized by the user according to the angle at which the display device 10 is viewed, etc.). Therefore, the pattern see-through phenomenon of the wiring TL can be prevented, reduced, or minimized.

[0232] For example, unlike the above-described embodiments, when the second wiring portions STL12 and STL22 extending in the second direction DR2 in the second non-active area NA2 are formed in a double-layer structure including the first wiring layer LTL and the second wiring layer UTL, like the first wiring portions STL11 and STL21 and the third wiring portions STL13 and STL23, etc., an edge portion of one side surface including the first wiring layer LTL may be exposed when an alignment error occurs along the first direction DR1. For example, depending on the angle at which the user views the display device 10, an edge portion of one side surface of the second metal layer MT12 including the first wiring layer LTL in the first direction DR1 may not be covered by at least one of the first metal layers MT11 and MT21 and the third metal layers MT13 and MT23 of the first wiring layer LTL and the second wiring layer UTL and may be exposed.

[0233] In an embodiment, the material included in the second metal layers MT12 and MT22 of the first wiring layer LTL and the second wiring layer UTL may be different from the material included in the first metal layers MT11 and MT21 and the third metal layers MT13 and MT23 of the first wiring layer LTL and the second wiring layer UTL. Due to the difference in light reflectivity (or the amount of light reflection) between the material included in the second metal layers MT12 and MT22 and the material included in the first metal layers MT11 and MT21 and the third metal layers MT13 and MT23, a pattern perspective phenomenon in which the pattern of the wiring TL is visually recognized by the user may occur.

[0234] For example, the second metal layer MT12 of the first wiring layer LTL may be formed of a material having a light reflectivity greater than that of the first metal layers MT11 and MT21 and the third metal layers MT13 and MT23 constituting the first wiring layer LTL and the second wiring layer UTL (e.g., titanium (Ti) having a UV reflectivity of approximately 5% to 6%) (e.g., aluminum (Al) having a UV reflectivity of approximately 87%). Therefore, when the second metal layers MT12 and MT22 of the first wiring layer LTL and the second wiring layer UTL are exposed at the same edge of the wiring TL, a pattern perspective phenomenon in which the pattern of the wiring TL is visually recognized by the user may occur.

[0235] For example, with Fig.10 and Fig.11 In the same form as the first wiring portion STL11 shown in FIG. 1 , when the second wiring portion STL12 has a double-layer structure and one side surface of the first wiring layer LTL (eg, Fig.11 When the left edge portion of the wiring TL is exposed, all of the side surfaces of the second metal layer MT12 of the first wiring layer LTL and the side surfaces of the second metal layer MT22 of the second wiring layer UTL may be exposed in one of the exposed side surfaces and close to one of the exposed side surfaces, and thus the amount of reflected light reflected from the second wiring portion STL12 may be relatively large. Therefore, a pattern perspective phenomenon of the wiring TL may occur.

[0236] In the above-described embodiment, in an area where the pattern perspective phenomenon of the wiring TL may occur (for example, in the second non-active area NA2 and / or a portion NA21 that is not covered by the light blocker LBM in the immediately adjacent peripheral area), the second wiring portions STL12 and STL22 of the wiring TL extending in the second direction DR2 can be formed as a single wiring layer, so that the amount of reflected light that can be reflected from the wiring TL can be reduced or minimized. Therefore, although alignment errors and the like occur in the process of forming the wiring TL including the first wiring layer LTL and the second wiring layer UTL, the second wiring portions STL12 and STL22 that can be exposed to the user can be formed as a single wiring layer, so that the amount of reflected light can be reduced or minimized. Therefore, the pattern perspective phenomenon of the wiring TL can be prevented, reduced or minimized.

[0237] Fig.15 is a plan view showing a portion of the sensor layer 150 according to an embodiment. For example, Fig.15 Shows Figure 8 A modified example of the embodiment regarding the structure of the first wiring TL1 and the second wiring TL2.

[0238] Fig.16 It shows that it can be set in Fig.15 A plan view of an embodiment of the wiring TL in the region F2 of FIG. Fig.16 Shows Fig.10 The embodiments of the present invention may be set in Fig.15 A modified example of the structure of the first wiring TL1 in the region F2 is shown in FIG.

[0239] Fig.17 is shown corresponding to Fig.16 A cross-sectional view of an embodiment of a cross section taken along line J-J'. Fig.18 is shown corresponding to Fig.16 A cross-sectional view of an embodiment of a cross-section of line J-J'. For example, Figure 17 to Figure 18 Shows the corresponding Fig.16 Different embodiments of the cross section along line J-J'.

[0240] Apart from Figures 1 to 14 In addition, refer to Figures 15 to 18 , the second wiring portion STL12 of the first wiring TL1 may include at least two wiring layers. For example, the second wiring portion STL12 of the first wiring TL1 may include a first wiring layer LTL and a second wiring layer UTL. The first wiring layer LTL of the second wiring portion STL12 may extend in the second direction DR2 in the non-active area NA (e.g., the second non-active area NA2). The second wiring layer UTL of the second wiring portion STL12 may be disposed on the insulating layer 152 covering the first wiring layer LTL, and may extend in the second direction DR2 in the non-active area NA (e.g., the second non-active area NA2) and overlap with the first wiring layer LTL of the second wiring portion STL12.

[0241] In the second wiring portion STL12, the second wiring layer UTL may have a width greater than that of the first wiring layer LTL and may cover the top surface of the first wiring layer LTL. For example, the second wiring layer UTL may be formed to have a width greater than that of the first wiring layer LTL by extending the width of the second wiring layer UTL, reducing the width of the first wiring layer LTL, or extending the width of the second wiring layer UTL and reducing the width of the first wiring layer LTL. In an embodiment, when viewed on a plane defined by the first direction DR1 and the second direction DR2, at least one of the first metal layer MT21 and the third metal layer MT23 of the second wiring layer UTL may completely cover the second metal layer MT12 of the first wiring layer LTL.

[0242] For example, Fig.17 As shown in the figure, the bottom surface of the second wiring layer UTL corresponding to the bottom surface of the third metal layer MT23 can cover the second metal layer MT12 and the third metal layer MT13 of the first wiring layer LTL, and at the same time have a width at least greater than the width of the second metal layer MT12 and the third metal layer MT13 of the first wiring layer LTL.

[0243] In an embodiment, Fig.18 As shown in , the second wiring layer UTL may be expanded to have a large width sufficient to cover portions corresponding to the top surface and the side surface of the first wiring layer LTL.

[0244] Each of the first wiring portion STL11 and the third wiring portion STL13 of the first wiring TL1 may have a single-layer structure or a multi-layer structure. For example, each of the first wiring portion STL11 and the third wiring portion STL13 of the first wiring TL1 may include a first wiring layer LTL and a second wiring layer UTL. In an embodiment, the first wiring layer LTL of each of the first wiring portion STL11 and the third wiring portion STL13 may be integrated with the first wiring layer LTL of the second wiring portion STL12. In an embodiment, the second wiring layer UTL of each of the first wiring portion STL11 and the third wiring portion STL13 may be disposed on the insulating layer 152 and overlapped with the first wiring layer LTL of the first wiring portion STL11 and the third wiring portion STL13, and may be integrated with the second wiring layer UTL of the second wiring portion STL12.

[0245] The second wiring portion STL22 of the second wiring TL2 may include at least two wiring layers. For example, the second wiring portion STL22 of the second wiring TL2 may include a first wiring layer LTL and a second wiring layer UTL. The first wiring layer LTL of the second wiring portion STL22 may extend in the second direction DR2 in the non-active area NA (e.g., the second non-active area NA2). The second wiring layer UTL of the second wiring portion STL22 may be disposed on the insulating layer 152 covering the first wiring layer LTL, and may extend in the second direction DR2 in the non-active area NA (e.g., the second non-active area NA2) and overlap with the first wiring layer LTL of the second wiring portion STL22.

[0246] In the second wiring portion STL22, the second wiring layer UTL may have a width greater than that of the first wiring layer LTL and may cover (e.g., completely cover) the top surface of the first wiring layer LTL. For example, in the second wiring portion STL22, the second wiring layer UTL may be formed with a width sufficient to cover the first wiring layer LTL in consideration of a process error range such as an alignment error that may occur in a manufacturing process of the display device 10.

[0247] In an embodiment, like the first wiring layer LTL of the first wiring TL1, the first wiring layer LTL of the second wiring TL2 may have a multilayer structure including a first metal layer MT11, a second metal layer MT12, and a third metal layer MT13, and like the second wiring layer UTL of the first wiring TL1, the second wiring layer UTL of the second wiring TL2 may have a multilayer structure including a first metal layer MT21, a second metal layer MT22, and a third metal layer MT23. When viewed on a plane defined by the first direction DR1 and the second direction DR2, at least one of the first metal layer MT21 and the third metal layer MT23 included in the second wiring layer UTL of the second wiring TL2 may completely cover the second metal layer MT12 included in the first wiring layer LTL of the second wiring TL2.

[0248] According to the above-described embodiment, in a visible area exposed to the user's field of vision and / or in an area set close to the visible area, the second wiring portions STL12 and STL22 of the wiring TL extending in the second direction DR2 may be formed to have a double-layer or more-layer structure including a first wiring layer LTL and a second wiring layer UTL, but may be formed such that the second wiring layer UTL covers the top surface of the first wiring layer LTL. For example, in a visible area, etc., the second metal layer MT12 of the first wiring layer LTL may be completely covered by the first metal layer MT21 and / or the third metal layer MT23 of the second wiring layer UTL. Therefore, the amount of light that may be reflected from the second wiring portions STL12 and STL22 that may be exposed to the user may be reduced or minimized, and the pattern perspective phenomenon of the wiring TL may be prevented, reduced or minimized.

[0249] Fig.19 It shows that it can be set in Figure 8 A plan view of an embodiment of the wiring TL and the wiring TL' in the region F1. For example, Fig.19 Shows about Fig.10 Another embodiment of an embodiment of .

[0250] Apart from Figures 1 to 18 In addition, refer to Fig.19, a plurality of wirings TL' (for example, a first wiring TL1' overlapping with the light blocker LBM in the second non-active area NA2) may also be disposed in a portion NA22 of the second non-active area NA2 covered by the light blocker LBM. In an embodiment, at least some of the plurality of wirings TL' may have a structure substantially the same as or similar to that of a wiring TL disposed in a portion NA21 of the second non-active area NA2 not covered by the light blocker LBM. For example, among the wirings TL and TL' passing through the second non-active area NA2, regardless of whether the wirings TL and TL' overlap with the light blocker LBM, each of the second wiring portions STL12 and STL12' extending in the second direction DR2 in the second non-active area NA2 may have substantially the same cross-sectional structure.

[0251] In an embodiment, the wirings TL and TL' passing through the second non-active area NA2 may include a single wiring layer in each of the second wiring portions STL12 and STL12', and the single wiring layer may be the first wiring layer LTL. However, the embodiment is not necessarily limited thereto. For example, as in Fig.13 and Fig.14 In the embodiment of the present invention, the wirings TL and TL' passing through the second non-active area NA2 may include a single wiring layer in each of the second wiring portions STL12 and STL12', and the single wiring layer may be the second wiring layer UTL. Fig.17 and Fig.18 In an embodiment, the wirings TL and TL' passing through the second non-active area NA2 may include a first wiring layer LTL and a second wiring layer UTL in each of the second wiring portions STL12 and STL12', and the second wiring layer UTL may completely cover the top surface of the first wiring layer LTL while having a width greater than that of the first wiring layer LTL.

[0252] The first wiring portion STL11' and the third wiring portion STL13' of the wiring TL' including each of the second wiring portions STL12' disposed in a portion NA22 of the second non-active area NA2 covered by the light blocker LBM may have a structure substantially the same as or similar to the structure of the first wiring portion STL11 and the third wiring portion STL13 of the wiring TL including each of the second wiring portions STL12 disposed in a portion NA21 of the second non-active area NA2 not covered by the light blocker LBM. For example, regardless of whether the wirings TL and TL' overlap with the light blocker LBM, the wirings TL and TL' may include each of the first wiring portions STL11 and STL11' and the third wiring portions STL13 and STL13' including a first wiring layer LTL and a second wiring layer UTL having substantially the same or similar widths.

[0253] Fig. 20 It shows that it can be set in Figure 8 A plan view of an embodiment of the wiring TL and the wiring TL' in the region F1. For example, Fig. 20 Shows Fig.19 A modified embodiment of the embodiment.

[0254] Apart from Figures 1 to 19 In addition, refer to Fig. 20 , the wiring TL disposed in a portion NA21 of the second non-active area NA2 that is not covered by the light blocker LBM and the wiring TL' disposed in a portion NA22 of the second non-active area NA2 that is covered by the light blocker LBM may include second wiring portions STL12 and STL12' having different structures. For example, the wiring TL' passing through a portion NA22 of the second non-active area NA2 that is covered by the light blocker LBM may include at least two wiring layers including a first wiring layer LTL and a second wiring layer UTL, and the first wiring layer LTL may have a width that is substantially the same as or similar to a width of the second wiring layer UTL. Depending on process errors, etc. (e.g., alignment errors), the first wiring layer LTL and the second wiring layer UTL of the wiring TL' may be completely overlapped at an edge, etc. or may not be partially overlapped. However, since the second wiring portion STL12' of the wiring TL' may be disposed in an area that cannot be visually recognized by a user, the pattern perspective phenomenon of the wiring TL' may not occur.

[0255] As in the above-described embodiment, the wiring TL disposed in a portion NA21 of the second non-active area NA2 that is not covered by the light blocker LBM and the wiring TL' disposed in a portion NA22 of the second non-active area NA2 that is covered by the light blocker LBM may have the same or different structures. For example, by comprehensively considering factors such as design conditions (such as the area of ​​the space in which the wirings TL and TL' may be disposed, the resistance of the wirings TL and TL', and the pattern perspective phenomenon), the wiring TL disposed in a portion NA21 of the second non-active area NA2 that is not covered by the light blocker LBM and the wiring TL' disposed in a portion NA22 of the second non-active area NA2 that is covered by the light blocker LBM may be formed to have the same structure or to have different structures.

[0256] While summarizing the detailed description, it will be appreciated by those skilled in the art that many variations and modifications may be made to the embodiments without substantially departing from the principles of the invention.
