That is, the first planarization layer 141 may cover the 1-1 wiring W1-1, the 1-2 wiring W1-2, the second wiring W2, the third wiring W3, and the fourth wiring W4. The first bridge wiring BW1 may be arranged above the first planarization layer 141. In an exemplary embodiment, the first planarization layer 141 may include, for example, an organic material such as polyimide, acrylic siloxane, carbon black, benzocyclobutene (BCB), or hexamethyldisiloxane (HMDSO). The first bridge wiring BW1 may include various conductive materials and have a single-layer structure or a multi-layer structure. In an exemplary embodiment, for example, the first bridge wiring BW1 may have a structure of Ti / Al / Ti.

[0068] As such, the first bridge wiring BW1 disposed above the first planarization layer 141 which is the 2-1 insulating layer contacts the 1-1 wiring W1-1 and the 1-2 wiring W1-2 through the contact hole CTH to electrically connect the 1-1 wiring W1-1 to the 1-2 wiring W1-2. Figure 2 As shown in FIG. 1 , the first bridge wiring BW1 has a convex shape in the direction (−x direction) opposite to the direction (+x direction) from the 1-1 wiring W1-1 and the 1-2 wiring W1-2 to the second wiring W2. Therefore, a sufficiently wide space can be defined between the center portion of the first bridge wiring BW1 and the second wiring W2.

[0069] The first pixel electrode PE1 and the second pixel electrode PE2 are arranged above the 2-2 insulating layer covering the first bridge wiring BW1. The 2-2 insulating layer may include, for example, a second planarization layer 142. That is, the second planarization layer 142 may cover the first bridge wiring BW1. The first pixel electrode PE1 and the second pixel electrode PE2 may be arranged above the second planarization layer 142. In an exemplary embodiment, the second planarization layer 142 may include, for example, an organic material such as polyimide, acrylic siloxane, carbon black, BCB, or HMDSO. The first pixel electrode PE1 and the second pixel electrode PE2 may include various conductive materials and have a single-layer structure or a multi-layer structure. In an exemplary embodiment, for example, the first pixel electrode PE1 and the second pixel electrode PE2 may include a reflective layer and a transparent conductive layer. In an exemplary embodiment, the reflective layer may include a metal such as aluminum (Al) or copper (Cu), and the transparent conductive layer may be arranged on the reflective layer and include indium tin oxide (ITO), indium zinc oxide (IZO), and indium oxide (In 2 O 3 ).

[0070] The first pixel electrode PE1 disposed over the second planarization layer 142 includes one side (in the +x direction) disposed over the second wiring W2. In addition, the other side (in the -x direction) of the first pixel electrode PE1 is disposed over the space between the 1-1 end W1-1a and the 1-2 end W1-2a.

[0071] Unlike the inorganic insulating layer including an inorganic material, since the first planarization layer 141 and the second planarization layer 142 include an organic material, the top surfaces of the first planarization layer 141 and the second planarization layer 142 are substantially flat despite the presence of elements arranged below the first planarization layer 141 and the second planarization layer 142. However, even if the organic layer includes an organic material, its top surface is not completely flat and has a slight bend corresponding to the elements arranged below it.

[0072] like Figure 3As shown in , the top surface of each of the first planarization layer 141 and the second planarization layer 142 has a slight bend. Since the second planarization layer 142 is arranged on the slightly flat top surface of the first planarization layer 141, the top surface of the second planarization layer 142 is relatively flatter than the top surface of the first planarization layer 141. However, the top surface of the second planarization layer 142 is still affected by the elements below the first planarization layer 141, and therefore has a curved shape. Therefore, the top surface of the second planarization layer 142 has a slightly convex shape (in the +z direction) above the second wiring W2. The top surface of the second planarization layer 142 has a slightly convex shape (in the +z direction) above the 1-1 wiring W1-1 and the 1-2 wiring W1-2. However, the top surface of the second planarization layer 142 has a flat shape between the 1-1 end W1-1a and the 1-2 end W1-2a. As described above, this is because the first bridge wiring BW1 has a convex shape in the direction (−x direction) opposite to the direction (+x direction) from the 1-1 wiring W1-1 and the 1-2 wiring W1-2 to the second wiring W2.

[0073] like Figure 3 As shown in FIG. 1 , the first pixel electrode PE1 arranged over the second planarization layer 142 including the top surface of this shape is relatively inclined with respect to the substrate 100. That is, a portion of the first pixel electrode PE1 arranged over the second wiring W2 and being one side (in the +x direction) of the first pixel electrode PE1 has a distance farther from the substrate 100 than the other side (in the −x direction) of the first pixel electrode PE1 arranged over the space between the 1-1 end W1-1a and the 1-2 end W1-2a.

[0074] like Figure 2 and Figure 4 As shown in , one side of the second pixel electrode PE2 (in the +x direction) is arranged above the third wiring W3, and the other side of the second pixel electrode PE2 (in the -x direction) is arranged above the space between the second wiring W2 and the third wiring W3. The top surface of the second planarization layer 142 has a slightly convex shape (in the +z direction) above the third wiring W3. However, between the second wiring W2 and the third wiring W3, more specifically, between the fourth wiring W4 arranged between the second wiring W2 and the third wiring W3 and the third wiring W3, the top surface of the second planarization layer 142 has a substantially flat shape. As shown in Figure 4As shown in FIG. 1 , the second pixel electrode PE2 arranged over the second planarization layer 142 having this shape is relatively inclined with respect to the substrate 100. That is, a portion of the second pixel electrode PE2 arranged over the third wiring W3 and being one side (in the +x direction) of the second pixel electrode PE2 has a distance farther from the substrate 100 than the other side (in the −x direction) of the second pixel electrode PE2 arranged over the space between the second wiring W2 and the third wiring W3.

[0075] Figure 5 is a plan view of a comparative example of a portion of a display device, and Figure 6 Is the edge of the display device Figure 5 In the display device according to the comparative technology, the first wiring W1 has a shape extending continuously in the first direction (-y direction) instead of having the 1-1 end W1-1a and the 1-2 end W1-2a separated from each other. Figure 4 As shown in , the top surface of the second planarization layer 142 has a convex shape (in the +z direction) in the portions corresponding to the first wiring W1 and the second wiring W2, respectively. In addition, one side (in the +x direction) of the first pixel electrode PE1 arranged above the second planarization layer 142 is approximately arranged above the second wiring W2, and the other side (in the -x direction) of the first pixel electrode PE1 is approximately arranged above the first wiring W1.

[0076] Therefore, with reference Figure 3 Unlike the first pixel electrode PE1 of the display device 1 in the exemplary embodiment shown in the description, the first pixel electrode PE1 of the display device is not inclined to one side relative to the substrate 100, and as shown in FIG. Figure 6 As shown in FIG. 1 , the first pixel electrode PE1 has a substantially flat shape, that is, both the edge of the first pixel electrode PE1 in the +x direction and the edge of the first pixel electrode PE1 in the −x direction are convex in the +z direction. Figure 4 As with the second pixel electrode PE2 of the exemplary embodiment shown in the display device 1 described above, the second pixel electrode PE2 of the comparative example of the display device is relatively inclined with respect to the substrate 100. This is because a portion of the second pixel electrode PE2 which is one side (in the +x direction) of the second pixel electrode PE2 and arranged above the third wiring W3 has a distance farther from the substrate 100 than the other side (in the -x direction) of the second pixel electrode PE2 which is arranged above the space between the second wiring W2 and the third wiring W3.

[0077] In a display device, in order to reduce external light reflection, a color filter is arranged above each pixel. For example, in the case of a pixel that emits red light, a red color filter that transmits only red light is arranged. For example, in the case of a pixel that emits blue light, a blue color filter that transmits only blue light is arranged. For example, in the case of a pixel that emits green light, a green color filter that transmits only green light is arranged. Therefore, for example, when external light that is white light is incident on the red color filter, the blue light and the green light are absorbed by the red color filter, and only the red light passes through the red color filter and is then reflected by the pixel electrode, passes through the red color filter again, and is emitted to the outside. Therefore, in the case of a display device including a color filter, the external light reflection is reduced to one third (1 / 3) compared to a display device that does not include a color filter.

[0078] However, in Figure 5 and Figure 6 In the comparative example of the display device shown in , the user can observe the color band due to the reflection of external light. Figure 6 As shown in , light reflected by the first pixel electrode PE1 having a substantially flat shape relative to the substrate 100 travels in the +z direction substantially perpendicular to the substrate 100. Figure 4 As shown in , light reflected by the second pixel electrode PE2 having a shape tilted relative to the substrate 100 travels at a specific angle that is not perpendicular to the substrate 100. Therefore, in the case where the second pixel electrode PE2 is a pixel electrode of a pixel emitting green light, as reflected light, the user observes light close to purple light mixed with red light and blue light in a direction perpendicular to the substrate 100, and observes light close to green light as reflected light at a specific angle that is not perpendicular to the substrate 100. Therefore, in the comparative example of the display device, the user observes color bands due to external light reflection.

[0079] In contrast, in the illustrated exemplary embodiment of the display device 1, not only the second pixel electrode PE2 but also the first pixel electrode PE1 is tilted relative to the substrate 100. Therefore, the user may not observe color banding due to external light reflection, or even if the user may observe color banding, the extent of the color banding may be minimized.

[0080] Similar to the second pixel electrode PE2, in order to tilt the first pixel electrode PE1 relative to the substrate 100, the top surface of the second planarization layer 142 is manufactured to have a substantially flat shape between the 1-1 end W1-1a and the 1-2 end W1-2a by separating the 1-1 end W1-1a from the 1-2 end W1-2a. For this purpose, the first bridge wiring BW1 electrically connecting the 1-1 end W1-1a to the 1-2 end W1-2a should not pass under the first pixel electrode PE1. Therefore, it is desirable that the orthographic projection image of the first pixel electrode PE1 on the substrate 100 does not overlap with the orthographic projection image of the first bridge wiring BW1 on the substrate 100. In the case of the second pixel electrode PE2, the orthographic projection image of the second pixel electrode PE2 on the substrate 100 does not overlap with the orthographic projection image of the second wiring W2 on the substrate 100.

[0081] For reference, Figure 2 As shown in , the arrangement relationship between the third pixel electrode PE3 and the wiring around it is similar to the arrangement relationship between the first pixel electrode PE1 and the wiring around it. That is, one side of the third pixel electrode PE3 (in the +x direction) is arranged above the second wiring W2. Moreover, the other side of the third pixel electrode PE3 (in the -x direction) is arranged above the space between the 1-1 end W1-1a and the 1-2 end W1-2a. Therefore, the third pixel electrode PE3 and the Figure 3 The first pixel electrodes PE1 arranged in the middle are similarly inclined.

[0082] Figure 2 FIG. 1 shows that the area of ​​a first pixel electrode PE1, the area of ​​a second pixel electrode PE2, and the area of ​​a third pixel electrode PE3 are different from each other. This is because the luminous efficiency may be different for each pixel. Figure 2 , it is shown that the number of second pixel electrodes PE2 per unit area is greater than the number of first pixel electrodes PE1 per unit area and the number of third pixel electrodes PE3 per unit area. Therefore, the area of ​​one second pixel electrode PE2 may be smaller than the area of ​​one first pixel electrode PE1 and the area of ​​one third pixel electrode PE3. The same applies to the following exemplary embodiments and their variations.

[0083] A pixel defining layer (not shown) may be arranged on the second planarization layer 142. The pixel defining layer defines a pixel by defining an opening corresponding to each sub-pixel (i.e., an opening exposing at least a central portion of each of the first to third pixel electrodes PE1 to PE3). The pixel defining layer may include an organic material such as polyimide or HMDSO.

[0084] In the case where the display device includes an organic light emitting diode as a display element, an intermediate layer (not shown) may be disposed above the first to third pixel electrodes PE1 to PE3 , and an opposing electrode (not shown) may be disposed above the intermediate layer.

[0085] The intermediate layer may include a low molecular weight material or a polymer material. In the case where the intermediate layer includes a low molecular weight material, the intermediate layer may have a structure stacked with a hole injection layer (hole injection layer, HIL), a hole transport layer (hole transport layer, HTL), an emission layer (emission layer, EML), an electron transport layer (electron transport layer, ETL), an electron injection layer (electron injection layer, EIL), etc. In an exemplary embodiment, the intermediate layer may include various organic materials, such as copper phthalocyanine (copper phthalocyanine, CuPc), N, N'-di (naphthalene-1-yl) -N, N'-diphenyl-benzidine (N, N'-Di (naphthalene-1-yl) -N, N'-diphenyl-benzidine, NPB) and tris-8-hydroxyquinoline aluminum (tris-8-hydroxyquinoline aluminum, Alq3). These layers can be provided by vacuum deposition.

[0086] In the case where the intermediate layer includes a polymer material, the intermediate layer may have a structure generally including an HTL and an EML. In this case, the HTL may include poly-3,4-ethylene dioxythiophene (PEDOT), and the EML may include a polymer material such as a polyphenylene vinylene (PPV)-based material and a polyfluorene-based material. In an exemplary embodiment, for example, the intermediate layer may be provided by screen printing, an inkjet printing method, and laser induced thermal imaging (LITI).

[0087] The structure of the intermediate layer is not limited to the above description and may have various structures. In addition, the intermediate layer may include a single whole covering the first to third pixel electrodes PE1 to PE3, or include a layer patterned to correspond to each of the first to third pixel electrodes PE1 to PE3.

[0088] The counter electrode may be arranged to cover the display area DA. That is, the counter electrode may be provided as a single integral body over the plurality of organic light emitting diodes to correspond to the first to third pixel electrodes PE1 to PE3. In an exemplary embodiment, for example, the counter electrode may include a substrate including ITO, IZO, or In 2 O 3 of a transparent conductive layer.

[0089] Despite Figure 2 , the first bridge wiring BW1 partially overlaps the third wiring W3 thereunder, but the present invention is not limited thereto. In an exemplary embodiment, for example, by ensuring a gap between the third wiring W3 and the 1-1 wiring W1-1, the first bridge wiring BW1 may not overlap the third wiring W3. This applies to the relationship between various bridge wirings and the wiring thereunder in the following exemplary embodiments and their modifications.

[0090] Figure 7 and Figure 8 1 is a cross-sectional view of another exemplary embodiment of a portion of the display device 1. As shown in the figure, the first pixel electrode PE1 may be electrically connected to the second wiring W2, and the second pixel electrode PE2 may be electrically connected to the third wiring W3. In this case, the second wiring W2 and the third wiring W3 may not be power lines as in the above exemplary embodiment, and may be wiring connected to one of the source electrode and the drain electrode of the TFT. In an alternative exemplary embodiment, the second wiring W2 and the third wiring W3 may be one of the source electrode and the drain electrode of the TFT. In this case, the TFT may be a driving TFT or an emission control TFT.

[0091] That is, in the organic light emitting display device, a pixel circuit may be arranged to each pixel to control the operation of each pixel, and the pixel circuit may include a plurality of TFTs and capacitors. The pixel circuit may be electrically connected to the corresponding pixel electrode. In this case, the second wiring W2 and the third wiring W3 may not be power lines as in the above exemplary embodiment, and may be electronic components (such as TFTs) electrically connected to the first pixel electrode PE1 and the second pixel electrode PE2 or wiring connected to the electronic components.

[0092] In this case, if Figure 7 and Figure 8As shown in , the first planarization layer 141 as the 2-1 insulating layer may be defined with a 2-1 through hole VH2-1 and a 3-1 through hole VH3-1. The 2-1 through hole VH2-1 is located above the second wiring W2, and the 3-1 through hole VH3-1 is located above the third wiring W3. In addition, the second planarization layer 142 as the 2-2 insulating layer on the 2-1 insulating layer may be defined with a 2-2 through hole VH2-2 and a 3-2 through hole VH3-2. The 2-2 through hole VH2-2 may correspond to the 2-1 through hole VH2-1, and the 3-2 through hole VH3-2 may correspond to the 3-1 through hole VH3-1. Therefore, the first pixel electrode PE1 may contact the second wiring W2 through the 2-1st and 2-2nd via holes VH2-1 and VH2-2, and the second pixel electrode PE2 may contact the third wiring W3 through the 3-1st and 3-2nd via holes VH3-1 and VH3-2.

[0093] Although in Figure 7 2 shows that the second planarization layer 142 covers the inner surface of the 2-1st through hole VH2-1, but the present invention is not limited thereto. In an exemplary embodiment, for example, since the 2-2nd through hole VH2-2 exposes the inner surface of the 2-1st through hole VH2-1, the inner surface of the 2-1st through hole VH2-1 may directly contact the first pixel electrode PE1. Figure 8 , the second planarization layer 142 covers the inner surface of the 3-1st through hole VH3-1, but the present invention is not limited thereto. In an exemplary embodiment, for example, since the 3-2nd through hole VH3-2 exposes the inner surface of the 3-1st through hole VH3-1, the inner surface of the 3-1st through hole VH3-1 may directly contact the second pixel electrode PE2.

[0094] During the manufacturing process, the materials of the first planarization layer 141 and the second planarization layer 142 may have properties such as photoresist. Therefore, the material for the first planarization layer 141 is arranged on the intermediate insulating layer 130 by a method such as slit coating, and the 2-1st through hole VH2-1 and the 3-1st through hole VH3-1 are defined by exposure and development. In an exemplary embodiment, for example, curing may be performed at 250 degrees Celsius for about 60 minutes. Then, the material for the second planarization layer 142 is provided to cover the first planarization layer 141 by a method such as slit coating, and the 2-2nd through hole VH2-2 and the 3-2nd through hole VH3-2 are defined by exposure and development. In addition, curing may be performed at 250 degrees Celsius for about 60 minutes. After providing the first planarization layer 141, before providing the second planarization layer 142, the first bridge wiring BW1, etc. may be provided by a deposition method using a fine metal mask.

[0095] like Figure 7 and Figure 8As shown in , when the first pixel electrode PE1 contacts the second wiring W2 corresponding thereto through the 2-1st through hole VH2-1 and the 2-2nd through hole VH2-2, and the second pixel electrode PE2 contacts the third wiring W3 corresponding thereto through the 3-1st through hole VH3-1 and the 3-2nd through hole VH3-2, the positions of the through holes may correspond to the outer edges of the pixel electrodes, not to the emission regions of the pixel electrodes. Fig. 9 As shown in , the first pixel electrode PE1 may include protrusions protruding in the +x direction and the -y direction, and contact the second wiring W2 corresponding thereto through the 2-1 through hole VH2-1 and the 2-2 through hole VH2-2 defined in the position where the protrusions are arranged. In addition, the second pixel electrode PE2 may include protrusions protruding in the +x direction and the +y direction, and contact the third wiring W3 corresponding thereto through the 3-1 through hole VH3-1 and the 3-2 through hole VH3-2 defined in the position where the protrusions are arranged. Like the first pixel electrode PE1, the third pixel electrode PE3 may include protrusions protruding in the +x direction and the -y direction, and contact the second wiring W2 corresponding thereto through the through hole defined in the position where the protrusions are arranged. For reference, in Fig. 9 In the figure, for the convenience of description, all through holes are represented by the reference symbol VH.

[0096] Although the first bridge wiring BW1 is described as being arranged between the first planarization layer 141 and the second planarization layer 142 and the first to third pixel electrodes PE1 to PE3 are described as being arranged above the second planarization layer 142 in the above exemplary embodiment, the present invention is not limited thereto. Fig.10 and Fig.11 As shown in FIG, the planarization layer 140 which is a second insulating layer may cover the 1-1 wiring W1-1, the 1-2 wiring W1-2, the second wiring W2 and the third wiring W3. For example, the first bridge wiring BW1, the first pixel electrode PE1 and the second pixel electrode PE2 may be arranged above the second insulating layer without contacting each other.

[0097] The first bridge wiring BW1 has a convex shape in the direction (-x direction) opposite to the direction (+x direction) from the 1-1 wiring W1-1 and the 1-2 wiring W1-2 to the second wiring W2. Therefore, a sufficiently wide space may be defined between the central portion of the first bridge wiring BW1 and the second wiring W2, and a portion of the first pixel electrode PE1 may be arranged in the space. Therefore, the first bridge wiring BW1 and the first pixel electrode PE1 may be arranged above the same layer. In this case, the first bridge wiring BW1 may include the same material as that of the first pixel electrode PE1, and be provided simultaneously during the provision of the first pixel electrode PE1. Therefore, the first bridge wiring BW1 may include the same material as that of the first pixel electrode PE1, and have the same layered structure as that of the first pixel electrode PE1.

[0098] Even in this case, Fig.10 and Fig.11 As shown in FIG. 1 , the first pixel electrode PE1 is relatively inclined with respect to the substrate 100, and similarly, the second pixel electrode PE2 is relatively inclined with respect to the substrate 100. Therefore, color banding caused by external light reflection may not occur or be minimized.

[0099] Since the first bridge wiring BW1 electrically connecting the 1-1 wiring W1-1 to the 1-2 wiring W1-2 does not contact the first pixel electrode PE1 during arrangement over the same layer as the first pixel electrode PE1, the orthographic projection image of the first pixel electrode PE1 on the substrate 100 does not overlap with the orthographic projection image of the first bridge wiring BW1 on the substrate 100. In addition, the orthographic projection image of the second pixel electrode PE2 on the substrate 100 does not overlap with the orthographic projection image of the second wiring W2 on the substrate 100.

[0100] Even in this case, as shown in the cross-sectional view of another exemplary embodiment of a portion of the display device 1 Fig.12 and Fig.13 As shown in FIG, a second through hole and a third through hole may also be defined in the planarization layer 140 which is a second insulating layer. The second through hole may be defined above the second wiring W2, and the third through hole may be defined above the third wiring W3. The first pixel electrode PE1 may contact the second wiring W2 through the second through hole, and the second pixel electrode PE2 may contact the third wiring W3 through the third through hole.

[0101] Fig.14 is a plan view of a portion of another exemplary embodiment of a display device, and Fig.15 is the edge of the display device 1 Fig.14Although in the above exemplary embodiment, the display device having a structure in which the first to third pixel electrodes PE1 to PE3 are similarly inclined with respect to the substrate 100 has been described, in the illustrated exemplary embodiment of the display device, the first to third pixel electrodes PE1 to PE3 that are substantially flat with respect to the substrate 100 are described.

[0102] The display device in the exemplary embodiment shown is different from the display device according to the exemplary embodiment described above in that the first wiring W1 arranged on the intermediate insulating layer 130 as the first insulating layer extends in the first direction (-y direction) and does not have the 1-1 end W1-1a or the 1-2 end W1-2a. Like the exemplary embodiment described above, the second wiring W2 is arranged above the intermediate insulating layer 130 as the first insulating layer, extends in the first direction (-y direction) to correspond to the first wiring W1, and is separated from the first wiring W1 in the +x direction. Therefore, along Fig.14 The cross section taken along line VI-VI has Figure 6 The shape shown in Figure 6 is a cross-sectional view of a comparative example of a display device taken along line VI-VI.

[0103] That is, in the illustrated exemplary embodiment of the display device, the top surface of the second planarization layer 142 has a convex shape (in the +z direction) in its portion corresponding to the first wiring W1 and the second wiring W2. In addition, one side (in the +x direction) of the first pixel electrode PE1 arranged above the second planarization layer 142 is approximately arranged above the second wiring W2, and the other side (in the -x direction) of the first pixel electrode PE1 is approximately arranged above the first wiring W1. Therefore, as Figure 6 As shown in , the first pixel electrode PE1 of the display device in the illustrated exemplary embodiment has a substantially flat shape with respect to the substrate 100 .

[0104] Unlike the exemplary embodiment of the display device described above, in the illustrated exemplary embodiment of the display device, the third wiring W3 arranged above the intermediate insulating layer 130 so that the second wiring W2 is located between the first wiring W1 and the third wiring W3 includes a 3-1 wiring W3-1 and a 3-2 wiring W3-2. The 3-1 wiring W3-1 extends in the first direction (-y direction) and includes a 3-1 end W3-1a at its end in the first direction (-y direction). The 3-2 wiring W3-2 faces the 3-1 end W3-1a by extending in a direction (+y direction) opposite to the first direction (-y direction), and includes a 3-2 end W3-2a separated from the 3-1 end W3-1a.

[0105] The third bridge wiring BW3 is arranged on a layer different from the layer on which the first wiring W1, the second wiring W2, the 3-1st wiring W3-1, the 3-2nd wiring W3-2, and the fourth wiring W4 are arranged. That is, the first wiring W1, the second wiring W2, the 3-1st wiring W3-1, the 3-2nd wiring W3-2, and the fourth wiring W4 are arranged above the first insulating layer, and the third bridge wiring BW3 is arranged above a layer different from the first insulating layer. In the exemplary embodiment, as shown in FIG. Fig.15 As shown in , for example, the third bridge wiring BW3 may be arranged above the 2-1st insulating layer on the intermediate insulating layer 130 which is the first insulating layer. The 2-1st insulating layer may include, for example, a first planarization layer 141. That is, the first planarization layer 141 may cover the first wiring W1, the second wiring W2, the 3-1st wiring W3-1, the 3-2nd wiring W3-2, and the fourth wiring W4. The third bridge wiring BW3 may be arranged above the first planarization layer 141. The material of the first planarization layer 141 is the same as described above. The third bridge wiring BW3 may include various conductive materials, and include a single-layer structure or a multi-layer structure. In an exemplary embodiment, for example, the third bridge wiring BW3 may have a structure of Ti / Al / Ti.

[0106] As described above, the third bridge wiring BW3 on the first planarization layer 141 as the 2-1 insulating layer contacts the 3-1 wiring W3-1 and the 3-2 wiring W3-2 through the contact hole CTH to electrically connect the 3-1 wiring W3-1 to the 3-2 wiring W3-2. Fig.14 As shown in , the third bridging wiring BW3 has a convex shape in the direction (+x direction) opposite to the direction (-x direction) from the 3-1 wiring W3-1 and the 3-2 wiring W3-2 to the second wiring W2. Therefore, a sufficiently wide space can be defined between the central portion of the third bridging wiring BW3 and the second wiring W2. The second pixel electrode PE2 is arranged above the space ensured in this way. That is, one side of the second pixel electrode PE2 is arranged above the space (in the +z direction) between the 3-1 end W3-1a and the 3-2 end W3-2a, and the other side of the second pixel electrode PE2 is arranged above the space between the center of the space between the 3-1 end W3-1a and the 3-2 end W3-2a and the second wiring W2. As a result, as shown in FIG. Figure 1 As shown in , since the second wiring W2 , the fourth wiring W4 , and the third wiring W3 do not pass under the second pixel electrode PE2 , the second pixel electrode PE2 is not inclined with respect to the substrate 100 .

[0107] As mentioned above, Figure 6 and Fig.15As shown in the exemplary embodiment of the display device, the first pixel electrode PE1 and the second pixel electrode PE2 are not inclined relative to the substrate 100. Therefore, the user may not observe color banding caused by external light reflection, or even when the user observes the color banding, the extent of the color banding may be minimized.

[0108] In order to allow the second pixel electrode PE2 not to tilt relative to the substrate 100, the top surface of the second planarization layer 142 is manufactured to have a substantially flat shape between the 3-1 end W3-1a and the 3-2 end W3-2a by separating the 3-1 end W3-1a from the 3-2 end W3-2a. For this purpose, the third bridge wiring BW3 should not pass under the second pixel electrode PE2, and the third bridge wiring BW3 electrically connects the 3-1 wiring W3-1 to the 3-2 wiring W3-2. Therefore, it is desired that the positive projection image of the second pixel electrode PE2 on the substrate 100 does not overlap with the positive projection image of the third bridge wiring BW3 on the substrate 100.

[0109] For reference, Fig.14 As shown in , the arrangement relationship between the third pixel electrode PE3 and the wiring around it is similar to the arrangement relationship between the first pixel electrode PE1 and the wiring around it. That is, one side of the third pixel electrode PE3 (in the +x direction) is arranged above the second wiring W2. In addition, the other side of the third pixel electrode PE3 (in the -x direction) is arranged above the first wiring W1. Therefore, Figure 6 Similar to the first pixel electrode PE1 shown in FIG. 1 , the third pixel electrode PE3 is not inclined with respect to the substrate 100 .

[0110] As described above, the third bridge wiring BW3 has a convex shape in the opposite direction (+x direction) to the direction (-x direction) from the 3-1 wiring W3-1 and the 3-2 wiring W3-2 to the second wiring W2. Therefore, it is preferable that the virtual straight line connecting the 3-1 wiring W3-1 to the 3-2 wiring W3-2 passes under one side of the second pixel electrode PE2. One side of the second pixel electrode PE2 is a portion of the second pixel electrode PE2 in the direction (+x direction) opposite to the direction (-x direction) toward the second wiring W2. With this configuration, the total length of the third bridge wiring BW3 can be minimized.

[0111] In the illustrated exemplary embodiment of the display device, the first wiring W1 may include, for example, a data line, and the second wiring W2 may include, for example, a power line. That is, the first wiring W1 may include a data line that transmits a data signal to a pixel disposed with the first pixel electrode PE1, and the second wiring W2 may include a power line that supplies power to the pixel disposed with the first pixel electrode PE1. The fourth wiring W4 disposed between the second wiring W2 and the third wiring W3 may include, for example, a data line, and the third wiring W3 may include, for example, a power line. That is, the fourth wiring W4 may include a data line that transmits a data signal to a pixel disposed with the second pixel electrode PE2, and the third wiring W3 may include a power line that supplies power to the pixel disposed with the second pixel electrode PE2.

[0112] However, the present invention is not limited thereto. In an exemplary embodiment, for example, the first pixel electrode PE1 may be electrically connected to one of the first wiring W1 and the second wiring W2, and the second pixel electrode PE2 may be electrically connected to the third bridge wiring BW3. In this case, the wiring electrically connected to the first pixel electrode PE1 may not be a data line or a power line, and may be a wiring connected to one of the source electrode and the drain electrode of the TFT. In an alternative exemplary embodiment, the wiring electrically connected to the first pixel electrode PE1 may be one of the source electrode and the drain electrode of the TFT. In this case, the TFT may include a driving TFT or an emission control TFT. The 3-1st wiring W3-1 and the 3-2nd wiring W3-2 electrically connected to the third bridge wiring BW3 may not be a data line or a power line, and may be a wiring connected to one of the source electrode and the drain electrode of the TFT. In an alternative exemplary embodiment, the wiring electrically connected to the third bridge wiring BW3 may be one of the source electrode and the drain electrode of the TFT.

[0113] In this case, a 2-1 through hole defined above the second wiring W2 may be defined in the first planarization layer 141 which is a 2-1 insulating layer. In addition, a 2-2 through hole and a third through hole may be defined in the second planarization layer 142 which is a 2-2 insulating layer on the 2-1 insulating layer. The 2-2 through hole corresponds to the 2-1 through hole, and the third through hole is located above the third bridge wiring BW3. Therefore, the first pixel electrode PE1 may contact the second wiring W2 through the 2-1 through hole and the 2-2 through hole, and the second pixel electrode PE2 may contact the third bridge wiring BW3 through the third through hole.

[0114] When the first pixel electrode PE1 contacts the second wiring W2 through the 2-1 through hole and the 2-2 through hole, and the second pixel electrode PE2 is electrically connected to the third wiring W3 through the third through hole by means of the third bridge wiring BW3, the position of the through hole may correspond to the outer edge of the pixel electrode instead of the emission area of ​​the pixel electrode. Fig.16 As shown in , the first pixel electrode PE1 may include protrusions protruding in the +x direction and the -y direction, and contact the second wiring W2 corresponding thereto through the 2-1 through hole and the 2-2 through hole defined in the position where the protrusions are arranged. In addition, the second pixel electrode PE2 may include protrusions protruding in the +x direction and the +y direction, and contact the third wiring W3 corresponding thereto by means of the third bridging wiring BW3 through the third through hole defined in the position where the protrusions are arranged. Like the first pixel electrode PE1, the third pixel electrode PE3 includes protrusions protruding in the +x direction and the -y direction, and contact the second wiring W2 corresponding thereto through the through hole defined in the position where the protrusions are arranged. For reference, in Fig.16 In the figure, for the convenience of description, all through holes are represented by the reference symbol VH.

[0115] exist Figures 14 to 16 In the above description, a case has been described where the first pixel electrode PE1 and the second pixel electrode PE2 are substantially parallel to the substrate 100 through the third bridge wiring BW3 near the second pixel electrode PE2. However, the present invention is not limited thereto.

[0116] In an exemplary embodiment, for example, a plan view of another exemplary embodiment of a portion of the display device 1 Fig.17 As shown in FIG. 1 , the first bridge wiring BW1 and the second bridge wiring BW2 may be arranged near the first pixel electrode PE1 , and the third bridge wiring BW3 may be arranged near the second pixel electrode PE2 .

[0117] The 1-1 wiring W1-1 extends in the first direction (-y direction) and has a 1-1 end W1-1a at its end in the first direction. The 1-2 wiring W1-2 faces the 1-1 end W1-1a by extending in the direction (+y direction) opposite to the first direction (-y direction). Therefore, the 1-2 wiring W1-2 includes a 1-2 end W1-2a separated from the 1-1 end W1-1a.

[0118] The 2-1 wiring W2-1 extends in the first direction (-y direction) and is separated from the 1-1 wiring W1-1 and the 1-2 wiring W1-2. In the first direction, the 2-1 wiring W2-1 includes a 2-1 end W2-1a at its end. The 2-2 wiring W2-2 extends in a direction (+y direction) opposite to the first direction (-y direction) and faces the 2-1 end W2-1a. Therefore, the 2-2 wiring W2-2 includes a 2-2 end W2-2a separated from the 2-1 end W2-1a.

[0119] The 3-1st wiring W3-1 extends in the first direction (-y direction) and is arranged so that the 2-1st wiring W2-1 is located between the 1-1st wiring W1-1 and the 3-1st wiring W3-1. In the first direction (-x direction), the 3-1st wiring W3-1 includes a 3-1st end W3-1a at its end. The 3-2nd wiring W3-2 extends in the direction (+y direction) opposite to the first direction (-y direction) and has a 3-2nd end W3-2a facing the 3-1st end W3-1a and separated from the 3-1st end W3-1a.

[0120] The first bridge wiring BW1 is arranged on a layer different from the layer on which the 1-1 wiring W1-1, the 1-2 wiring W1-2, the 2-1 wiring W2-1, the 2-2 wiring W2-2, the 3-1 wiring W3-1, and the 3-2 wiring W3-2 are arranged. That is, the 1-1 wiring W1-1, the 1-2 wiring W1-2, the 2-1 wiring W2-1, the 2-2 wiring W2-2, the 3-1 wiring W3-1, and the 3-2 wiring W3-2 are arranged on the first insulating layer, and the first bridge wiring BW1 is arranged on a layer different from the first insulating layer. In an exemplary embodiment, for example, the first bridge wiring BW1 may be arranged on the 2-1 insulating layer on the intermediate insulating layer 130 which is the first insulating layer. The 2-1 insulating layer may include, for example, the first planarization layer 141. That is, the first planarization layer 141 may cover the 1-1st wiring W1-1, the 1-2nd wiring W1-2, the 2-1st wiring W2-1, the 2-2nd wiring W2-2, the 3-1st wiring W3-1, and the 3-2nd wiring W3-2. The first bridge wiring BW1 may be disposed on the first planarization layer 141. The configuration of the first planarization layer 141 is the same as described above.

[0121] The first bridge wiring BW1 disposed over the first planarization layer 141 which is the 2-1 insulating layer contacts the 1-1 wiring W1-1 and the 1-2 wiring W1-2 to electrically connect the 1-1 wiring W1-1 to the 1-2 wiring W1-2. Fig.17As shown in , the first bridge wiring BW1 has a convex shape in the direction (−x direction) opposite to the direction (+x direction) from the 1-1 wiring W1-1 and the 1-2 wiring W1-2 to the 2-1 wiring W2-1.

[0122] Similar to the first bridge wiring BW1, the second bridge wiring BW2 disposed over the first planarization layer 141 which is the 2-1 insulating layer contacts the 2-1 wiring W2-1 and the 2-2 wiring W2-2 to electrically connect the 2-1 wiring W2-1 to the 2-2 wiring W2-2. Fig.17 As shown in , the second bridge wiring BW2 has a convex shape in the direction (+x direction) opposite to the direction (−x direction) from the 2-1 wiring W2-1 and the 2-2 wiring W2-2 to the 1-1 wiring W1-1.

[0123] Similar to the first bridge wiring BW1, the third bridge wiring BW3 disposed over the first planarization layer 141 which is the 2-1 insulating layer contacts the 3-1 wiring W3-1 and the 3-2 wiring W3-2 to electrically connect the 3-1 wiring W3-1 to the 3-2 wiring W3-2. Fig.17 As shown in , the third bridge wiring BW3 has a convex shape in the direction (+x direction) opposite to the direction (−x direction) from the 3-1st wiring W3-1 and the 3-2nd wiring W3-2 to the 2-1st wiring W2-1.

[0124] The first pixel electrode PE1 and the second pixel electrode PE2 are arranged above the second planarization layer 142 which is the 2-2 insulating layer covering the first bridge wiring BW1 to the third bridge wiring BW3. One side of the first pixel electrode PE1 is arranged in the space between the 1-1 end W1-1a and the 1-2 end W1-2a, and the other side of the first pixel electrode PE1 is arranged in the space between the 2-1 end W2-1a and the 2-2 end W2-2a. Therefore, the first pixel electrode PE1 has a substantially flat shape relative to the substrate 100. One side of the second pixel electrode PE2 is arranged above the space between the 3-1 end W3-1a and the 3-2 end W3-2a. The other side of the second pixel electrode PE2 may be arranged above the space between the center of the space between the 3-1 end W3-1a and the 3-2 end W3-2a and the 2-1 wiring W2-1, or above the space between the center of the space between the 3-1 end W3-1a and the 3-2 end W3-2a and the 2-2 wiring W2-2. With this configuration, the second pixel electrode PE2 has a shape that is substantially parallel to the substrate 100.

[0125] As described above, the third bridge wiring BW3 has a convex shape in the opposite direction (+x direction) to the direction (-x direction) from the 3-1 wiring W3-1 and the 3-2 wiring W3-2 to the 2-1 wiring W2-1. Therefore, it is preferred that, relative to the center of the second pixel electrode PE2, in the direction (+x direction) opposite to the direction (-x direction) toward the 2-1 wiring W2-1 or in the direction (+x direction) opposite to the direction (-x direction) toward the 2-2 wiring W2-2, a virtual straight line connecting the 3-1 wiring W3-1 to the 3-2 wiring W3-2 passes under one side of the second pixel electrode PE2. With this configuration, the total length of the third bridge wiring BW3 can be minimized.

[0126] In the illustrated exemplary embodiment of the display device, the 1-1th wiring W1-1 may include, for example, a data line, and the 2-1th wiring W2-1 may include, for example, a power line.

The fourth wiring W4 arranged between the 2-1th wiring W2-1 and the 3-1th wiring W3-1 may include, for example, a data line, and the 3-1th wiring W3-1 may include, for example, a power line. That is, the fourth wiring W4 may include a data line that transmits a data signal to a pixel arranged with the second pixel electrode PE2, and the 3-1th wiring W3-1 may include a power line that supplies power to the pixel arranged with the second pixel electrode PE2.

[0127] However, the present invention is not limited thereto. In an exemplary embodiment, for example, the first pixel electrode PE1 may be electrically connected to the second bridge wiring BW2, and the second pixel electrode PE2 may be electrically connected to the third bridge wiring BW3. In this case, the wiring electrically connected to the first pixel electrode PE1 through the second bridge wiring BW2 may not be a data line or a power line, and may be a wiring connected to one of the source electrode and the drain electrode of the TFT. In an alternative exemplary embodiment, the wiring electrically connected to the first pixel electrode PE1 may be one of the source electrode and the drain electrode of the TFT. In this case, the TFT may include a driving TFT or an emission control TFT. The wiring electrically connected to the second pixel electrode PE2 through the third bridge wiring BW3 may not be a data line or a power line, and may be a wiring connected to one of the source electrode and the drain electrode of the TFT. In an alternative exemplary embodiment, the wiring electrically connected to the second pixel electrode PE2 may be one of the source electrode and the drain electrode of the TFT.

[0128] In this case, the second planarization layer 142, which is the 2-2 insulating layer, may be defined with a second through hole and a third through hole. The second through hole is defined above the second bridge wiring BW2, and the third through hole is defined above the third bridge wiring BW3. Therefore, the first pixel electrode PE1 may contact the second bridge wiring BW2 through the second through hole, and the second pixel electrode PE2 may contact the third bridge wiring BW3 through the third through hole.

[0129] When the first pixel electrode PE1 contacts the second bridge wiring BW2 through the second through hole, and the second pixel electrode PE2 contacts the third bridge wiring BW3 through the third through hole, the position of the through hole may correspond to the outer edge of the pixel electrode instead of the emission area of ​​the pixel electrode. Fig.18 As shown in , the first pixel electrode PE1 may include protrusions protruding in the +x direction and the +y direction, and contact the second bridge wiring BW2 through a second through hole defined in the position where the protrusion is arranged. In addition, the second pixel electrode PE2 may include protrusions protruding in the +x direction and the -y direction, and contact the third bridge wiring BW3 through a third through hole defined in the position where the protrusion is arranged. Like the first pixel electrode PE1, the third pixel electrode PE3 may include protrusions protruding in the +x direction and the +y direction, and contact the bridge wiring corresponding thereto through a through hole defined in the position where the protrusion is arranged. For reference, in Fig.18 In the figure, for the convenience of description, all through holes are represented by the reference symbol VH.

[0130] In order to allow the first pixel electrode PE1 not to tilt relative to the substrate 100, the top surface of the second planarization layer 142 has a substantially flat shape between the 1-1 end W1-1a and the 1-2 end W1-2a by separating the 1-1 end W1-1a from the 1-2 end W1-2a, and the top surface of the second planarization layer 142 has a substantially flat shape between the 2-1 end W2-1a and the 2-2 end W2-2a by separating the 2-1 end W2-1a from the 2-2 end W2-2a. In order to allow the second pixel electrode PE2 not to tilt relative to the substrate 100, the top surface of the second planarization layer 142 is manufactured to have a substantially flat shape between the 3-1 end W3-1a and the 3-2 end W3-2a by separating the 3-1 end W3-1a from the 3-2 end W3-2a. For this purpose, it is desirable that the orthographic projection image of the first pixel electrode PE1 on the substrate 100 does not overlap with the orthographic projection images of the first bridge wiring BW1 and the second bridge wiring BW2 on the substrate 100.
