In this case, when the user views the display panel 10 from the +X direction to the -X direction at a side viewing angle, the signal lines TS1, TS2...TS m ,TSm+1 ...the side facing the +X direction will respectively generate reflected light with the colors of the first color resist CR1, the second color resist CR2, the third color resist CR3, the first color resist CR1, the second color resist CR2, the third color resist CR3..., for example, red reflected light, green reflected light, blue reflected light, red reflected light, green reflected light, blue reflected light... Therefore, the above-mentioned colored lights will be mixed to form white reflected light. Similarly, when the user views the display panel 10 from the -X direction to the +X direction with a side viewing angle, white reflected light will also be seen. It should be particularly noted that compared to Figure 1C The display panel shown in this embodiment does not cause color difference at side viewing angles due to reflections from the signal lines.

[0043] Reference Figure 1A as well as Figure 3 In the first embodiment of the present invention, the display panel 10 includes a first substrate 100 , a pixel array layer PL, and a color resist layer 300 .

In some embodiments, the display panel 10 is not a touch panel, and the signal lines TP1, TP2...TP m ,TP m+1 ...may be a heating wire for heating.

[0046] The color resist layer 300 is disposed on the pixel array layer PL and includes a plurality of pixel units PX. The pixel units PX are sequentially arranged along the X direction, and each pixel unit PX includes a first color resist CR1, a second color resist CR2, and a third color resist CR3 sequentially arranged along the X direction, wherein the colors of the first color resist CR1, the second color resist CR2, and the third color resist CR3 are different. In the embodiment, the colors of the first color resist CR1, the second color resist CR2, and the third color resist CR3 are red, green, and blue, respectively, but are not limited thereto. In some embodiments, the colors of the first color resist CR1, the second color resist CR2, and the third color resist CR3 are green, blue, and red, respectively. In some embodiments, the colors of the first color resist CR1, the second color resist CR2, and the third color resist CR3 are blue, red, and green, respectively.

[0047] It should be noted that, Figure 3 Only a schematic view of a partial region of the display panel 10 is shown. In fact, Figure 3 The structure shown is periodically arranged on the first substrate 100.

[0048] As Figure 3 As shown, the signal line TP1 corresponds to the junction of the first color resist CR1 and the second color resist CR2; the signal line TP2 corresponds to the junction of the third color resist CR3 and the first color resist CR1; and the signal line TP3 corresponds to the junction of the second color resist CR2 and the third color resist CR3. The gap between two adjacent signal lines corresponds to 2 color resists. Specifically, the gap between the adjacent signal line TP1 and the signal line TP2 corresponds to one second color resist CR2 and one third color resist CR3; the gap between the adjacent signal line TP2 and the signal line TP3 corresponds to one first color resist CR1 and one second color resist CR2; and the gap between the adjacent signal line TP3 and the signal line TP4 (not shown) corresponds to one third color resist CR3 and one first color resist CR1.

[0049] When the user views the display panel 10 with a lateral viewing angle from the +X direction to the -X direction, the light reflected by the signal line TP1 and penetrating the second color resist CR2, the light reflected by the signal line TP2 and penetrating the first color resist CR1, and the light reflected by the signal line TP3 and penetrating the third color resist CR3 will be seen at the same time. The above-mentioned light will be mixed into white light. As described above, Figure 3 The structure shown is periodically arranged on the first substrate 100, so that when the user views the display panel 10 with a lateral viewing angle from the +X direction to the -X direction, white reflected light will be seen.

[0050] Similarly, when a user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the user will see light reflected by the signal line TP1 and penetrating the first color resist CR1, light reflected by the signal line TP2 and penetrating the third color resist CR3, and light reflected by the signal line TP3 and penetrating the second color resist CR2. The above-mentioned light will mix to white light. As described above, Figure 3 The structure shown is periodically arranged on the first substrate 100, so that when a user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the user will see white reflected light.

[0051] The display panel 10 of the first embodiment will not cause color difference at a lateral viewing angle due to reflection of light by the signal lines.

[0052] Compared with Figure 2 The signal lines TS1, TS2, …, TS m , TS m+1 … of the embodiment shown are arranged under the black matrix BM at the junctions of the adjacent color resists CR1, CR2, CR3. Figure 3 The distribution density of the signal lines TP1, TP2, …, TP m , TP m+1 … in the embodiment shown is reduced to one half. Accordingly, the problem of dark state light leakage and contrast reduction at the normal viewing angle / lateral viewing angle caused by too high distribution density of the signal lines can be avoided. In some embodiments, Figure 3 The central (normal viewing angle) contrast of the display panel in Figure 2 is increased by 10%, Figure 3 The lateral (lateral viewing angle) contrast of the display panel in Figure 2 is increased by 17%.

The gaps between two adjacent signal lines correspond to 4 color resistors. Specifically, the gap between the adjacent signal line TP1 and the signal line TP2 corresponds to two second color resistors CR2, one third color resistor CR3 and one first color resistor CR1; the gap between the adjacent signal line TP2 and the signal line TP3 corresponds to two third color resistors CR3, one first color resistor CR1 and one second color resistor CR2; the gap between the adjacent signal line TP3 and the signal line TP4 (not shown) corresponds to two first color resistors CR1, one second color resistor CR2 and one third color resistor CR3.

[0055] When a user views the display panel 10 from the +X direction toward the -X direction at a side angle, they will simultaneously see the light reflected by the signal line TP1 and passing through the second color resist CR2, the light reflected by the signal line TP2 and passing through the third color resist CR3, and the light reflected by the signal line TP3 and passing through the first color resist CR1. The above light will mix to form white light. As described above, Figure 4 The structures shown are periodically arranged on the first substrate 100 . Therefore, when a user views the display panel 10 from the +X direction to the −X direction at a side viewing angle, white reflected light is seen.

[0056] Similarly, when a user views the display panel 10 from the -X direction toward the +X direction at a side angle, they will simultaneously see the light reflected by the signal line TP1 and passing through the first color resist CR1, the light reflected by the signal line TP2 and passing through the second color resist CR2, and the light reflected by the signal line TP3 and passing through the third color resist CR3. The above light will mix to form white light. As described above, Figure 4 The structures shown are periodically arranged on the first substrate 100 . Therefore, when a user views the display panel 10 from the −X direction to the +X direction at a side viewing angle, white reflected light is seen.

[0057] The display panel 10 of the second embodiment will not have color difference at side viewing angles due to the reflection of the signal lines.

[0058] Compared to Figure 2 In the embodiment shown, signal lines TS1, TS2, TS3 are arranged below the black matrix BM at the junction of adjacent color resists CR1, CR2, CR3. m ,TS m+1 ...the situation, Figure 4 The signal lines TP1, TP2, ...TP of the second embodiment are shown.m ,TP m+1 The distribution density of the signal lines TP is reduced to one fourth. Accordingly, the problem of light leakage in dark state and contrast ratio reduction in normal viewing angle / side viewing angle caused by too high distribution density of the signal lines can be avoided.

[0059] Referring to Figure 1A and Figure 5 , a schematic diagram of a display panel according to a third embodiment of the present application is shown. It should be noted that, Figure 5 only a schematic diagram of a partial area of the display panel of the third embodiment is shown. In fact, Figure 5 The structure shown is periodically arranged on the first substrate 100.

[0060] The display panel of the third embodiment ( Figure 5 ) has substantially the same configuration as the display panel of the first embodiment ( Figure 3 ). The display panel of the third embodiment is different from the display panel of the first embodiment in that the signal line TP1 corresponds to the junction of the first color resist CR1 and the second color resist CR2; the signal line TP2 corresponds to the junction of the third color resist CR3 and the first color resist CR1; and the signal line TP3 corresponds to the junction of the second color resist CR2 and the third color resist CR3. The gap between two adjacent signal lines corresponds to five color resists. Specifically, the gap between the adjacent signal line TP1 and the signal line TP2 corresponds to two second color resists CR2, two third color resists CR3 and one first color resist CR1; the gap between the adjacent signal line TP2 and the signal line TP3 corresponds to two first color resists CR1, two second color resists CR2 and one third color resist CR3; and the gap between the adjacent signal line TP3 and the signal line TP4 (not shown) corresponds to two third color resists CR3, two first color resists CR1 and one second color resist CR2.

[0061] When the user views the display panel 10 with a side viewing angle from the +X direction to the -X direction, the user will see the light reflected by the signal line TP1 and penetrating the second color resist CR2, the light reflected by the signal line TP2 and penetrating the first color resist CR1, and the light reflected by the signal line TP3 and penetrating the third color resist CR3. The above-mentioned lights will mix into white light. As mentioned above, Figure 5 The structure shown is periodically arranged on the first substrate 100. Therefore, when the user views the display panel 10 with a side viewing angle from the +X direction to the -X direction, the user will see white reflected light.

[0062] Similarly, when a user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the user will see light reflected by the signal line TP1 and penetrating the first color resist CR1, light reflected by the signal line TP2 and penetrating the third color resist CR3, and light reflected by the signal line TP3 and penetrating the second color resist CR2. The above-mentioned light will be mixed into white light. As mentioned above, Figure 5 The structure shown is periodically arranged on the first substrate 100. Therefore, when a user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the user will see white reflected light.

[0063] The display panel 10 of the third embodiment will not cause color difference at a lateral viewing angle due to reflection of light by the signal lines.

[0064] Compared with the first embodiment, Figure 2 The signal lines TS1, TS2, …, TS m , TS m+1 … of the embodiment shown are arranged under the black matrix BM at the junctions of the adjacent color resists CR1, CR2, CR3. Figure 5 The distribution density of the signal lines TP1, TP2, …, TP m , TP m+1 … of the third embodiment shown is reduced to one fifth. Accordingly, the problem of dark state light leakage and contrast ratio reduction at the normal viewing angle / lateral viewing angle caused by too high distribution density of the signal lines can be avoided.

[0065] Referring to Figure 1A and Figure 6 , schematic diagrams of a display panel according to a fourth embodiment of the present application are shown. It should be noted that, Figure 6 Only schematic diagrams of a partial area of the display panel of the fourth embodiment are shown. In fact, Figure 6 The structure shown is periodically arranged on the first substrate 100.

[0066] The display panel of the fourth embodiment ( Figure 6 ) is similar to the display panel of the first embodiment ( Figure 3The configuration of the display panel of the fourth embodiment is substantially the same as that of the first embodiment, and thus is not described again. The display panel of the fourth embodiment differs from the display panel of the first embodiment in that the signal line TP1 corresponds to the junction of the first color resist CR1 and the second color resist CR2; the signal line TP2 corresponds to the junction of the second color resist CR2 and the third color resist CR3; and the signal line TP3 corresponds to the junction of the third color resist CR3 and the first color resist CR1. The gap between two adjacent signal lines corresponds to seven color resists. Specifically, the gap between the adjacent signal line TP1 and the signal line TP2 corresponds to three second color resists CR2, two third color resists CR3, and two first color resists CR1; the gap between the adjacent signal line TP2 and the signal line TP3 corresponds to three third color resists CR3, two first color resists CR1, and two second color resists CR2; and the gap between the adjacent signal line TP3 and the signal line TP4 (not shown) corresponds to three first color resists CR1, two second color resists CR2, and two third color resists CR3.

[0067] When the user views the display panel 10 from the +X direction toward the -X direction at a lateral viewing angle, the user will simultaneously see the light reflected by the signal line TP1 and penetrating the second color resist CR2, the light reflected by the signal line TP2 and penetrating the third color resist CR3, and the light reflected by the signal line TP3 and penetrating the first color resist CR1. The above-mentioned lights will mix to white light. As described above, Figure 6 The structure shown is periodically arranged on the first substrate 100, and thus, when the user views the display panel 10 from the +X direction toward the -X direction at a lateral viewing angle, the user will see white reflected light.

[0068] Similarly, when the user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the user will simultaneously see the light reflected by the signal line TP1 and penetrating the first color resist CR1, the light reflected by the signal line TP2 and penetrating the second color resist CR2, and the light reflected by the signal line TP3 and penetrating the third color resist CR3. The above-mentioned lights will mix to white light. As described above, Figure 6 The structure shown is periodically arranged on the first substrate 100, and thus, when the user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the user will see white reflected light.

[0069] The display panel 10 of the fourth embodiment will not have color difference at a lateral viewing angle due to the reflection of the signal lines.

Accordingly, the problem of light leakage in dark state and contrast ratio reduction in normal viewing angle / side viewing angle caused by too high distribution density of the signal lines can be avoided.

[0071] It should be noted that, as shown in the first embodiment to the fourth embodiment, when the gap between two adjacent signal lines corresponds to N color resistances, where N is a positive integer greater than 1 and N is not a multiple of 3, the problem of light leakage in dark state and contrast ratio reduction in normal viewing angle / side viewing angle caused by too high distribution density of the signal lines can be avoided, and the display panel will not have color difference in side viewing angle due to reflection of the signal lines.

[0084] Referring to Figure 1A and Figure 8 , a schematic diagram of a display panel according to a sixth embodiment of the present application is shown. It should be noted that, Figure 8 only a schematic diagram of a partial region of the display panel of the sixth embodiment is shown. In fact, Figure 8 The structures shown are arranged periodically on the first substrate 100.

[0085] The display panel of the sixth embodiment of the present application ( Figure 8 ) has substantially the same configuration as the display panel of the fifth embodiment of the present application ( Figure 7 ). Therefore, the display panel of the sixth embodiment of the present application is not described in detail. The display panel of the sixth embodiment of the present application is different from the display panel of the fifth embodiment of the present application in that each of the plurality of signal line groups TG1, TG2, …, TG n ,TG n+1 … includes three signal lines arranged along the X direction.

[0086] In addition, the gap between two adjacent ones of the signal line groups TG1, TG2, …, TG n ,TG n+1 … corresponds to two color resists. Specifically, as shown in Figure 8 , the gap between the two signal line groups TG1, TG2 corresponds to two color resists, and the gap between the two signal line groups TG2, TG3 corresponds to two color resists.

[0087] As shown in Figure 8As shown, signal line TP1 corresponds to the junction of the first color resist CR1 and the second color resist CR2; signal line TP2 corresponds to the junction of the second color resist CR2 and the third color resist CR3; signal line TP3 corresponds to the junction of the third color resist CR3 and the first color resist CR1; signal line TP4 corresponds to the junction of the second color resist CR2 and the third color resist CR3; signal line TP5 corresponds to the junction of the third color resist CR3 and the first color resist CR1; signal line TP6 corresponds to the junction of the first color resist CR1 and the second color resist CR2; signal line TP7 corresponds to the junction of the third color resist CR3 and the first color resist CR1; signal line TP8 corresponds to the junction of the first color resist CR1 and the second color resist CR2; and signal line TP9 corresponds to the junction of the second color resist CR2 and the third color resist CR3.

[0088] When the user views the display panel 10 from the +X direction toward the -X direction at a lateral viewing angle, the user will simultaneously see light reflected by the signal line TP1 and penetrating the second color resist CR2, light reflected by the signal line TP2 and penetrating the third color resist CR3, light reflected by the signal line TP3 and penetrating the first color resist CR1, light reflected by the signal line TP4 and penetrating the third color resist CR3, light reflected by the signal line TP5 and penetrating the first color resist CR1, and light reflected by the signal line TP6 and penetrating the second color resist CR2, light reflected by the signal line TP7 and penetrating the first color resist CR1, light reflected by the signal line TP8 and penetrating the second color resist CR2, and light reflected by the signal line TP9 and penetrating the third color resist CR3. The above-mentioned light will mix to white light. As described above, Figure 8 The structure shown is periodically arranged on the first substrate 100, and thus, when the user views the display panel 10 from the +X direction toward the -X direction at a lateral viewing angle, the user will see white reflected light.

[0089] Similarly, when the user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the user will simultaneously see light reflected by the signal line TP1 and penetrating the first color resist CR1, light reflected by the signal line TP2 and penetrating the second color resist CR2, light reflected by the signal line TP3 and penetrating the third color resist CR3, light reflected by the signal line TP4 and penetrating the second color resist CR2, light reflected by the signal line TP5 and penetrating the third color resist CR3, and light reflected by the signal line TP6 and penetrating the first color resist CR1, light reflected by the signal line TP7 and penetrating the third color resist CR3, light reflected by the signal line TP8 and penetrating the first color resist CR1, and light reflected by the signal line TP9 and penetrating the second color resist CR2. The above-mentioned light will mix to white light. As described above, Figure 8 The structure shown is periodically arranged on the first substrate 100, and thus, when the user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the user will see white reflected light.

[0090] The display panel 10 of the sixth embodiment does not cause color difference at the side view angle due to the reflection of the signal lines.

[0091] Compared with Figure 2 The signal lines TS1, TS2, …, TS m , TS m+1 … are arranged under the black matrix BM at the junction of the adjacent color resist CR1, CR2, CR3 in the illustrated embodiment. Figure 7 The distribution density of the signal lines TP1, TP2, …, TP m , TP m+1 … in the illustrated embodiment is reduced to one third. Accordingly, the problem of light leakage in the dark state and the contrast reduction at the normal view angle / side view angle due to the too high distribution density of the signal lines can be avoided.

[0092] It should be noted that, as shown in the fifth embodiment to the sixth embodiment, when each signal line group includes M signal lines, and the gap between the adjacent signal line groups corresponds to N color resist, M is a positive integer greater than 1, the sum of M and N is a positive integer greater than 3, and the sum of M and N is not a multiple of 3, the problem of light leakage in the dark state and the contrast reduction at the normal view angle / side view angle due to the too high distribution density of the signal lines can be avoided, and the display panel does not cause color difference at the side view angle due to the reflection of the signal lines.

[0093] In summary, the display panel provided by the embodiments of the present application has a special signal line configuration, and does not need to arrange signal lines at each color resist junction, thereby avoiding the problem of light leakage in the dark state and the contrast reduction at the normal view angle / side view angle, and the display panel does not cause color difference at the side view angle due to the reflection of the signal lines.
