N+1 , TP N+2 , TP N+3 …TP 2NThe third signal line TP is disposed in the second region R2 and below the boundary between the third color resists CR3 and the first color resists CR1 in the second region R2. 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N The plurality of second color resists CR2 and the plurality of third color resists CR3 are disposed in the third region R3 and below the boundary between the plurality of second color resists CR2 and the plurality of third color resists CR3 in the third region R3. N is a positive integer and is less than or equal to M.

[0048] In some embodiments, N is equal to M. That is, a first signal line TP1, TP2, TP3, TP4, TP5, TP6, TP7, TP8, TP9, TP10, TP11, TP21, TP22, TP3, TP43, TP54, TP15, TP16, TP17, TP18, TP29, TP20, TP21, TP22, N In the second region R2, each junction between the third color resistor CR3 and the first color resistor CR1 is configured with a second signal line TP.

[0049] Accordingly, when a user views the display panel 10 from the +X direction to the -X direction at a side viewing angle, the first signal lines TP1, TP2, TP3, TP4, TP5, TP6, TP7, TP8, TP9, TP10, TP11, TP2, TP3, TP4, TP50, TP12, TP13, TP14, TP15, TP16, TP17, TP N The side surfaces facing the +X direction will respectively generate reflected light having the color of the second color resist CR2, for example, green reflected light; the second signal lines TP N+1 , TP N+2 , TP N+3 …TP 2N The side surfaces facing the +X direction will respectively generate reflected light having the color of the first color resist CR1, for example, red reflected light; the third signal lines TP 2N+1 , TP 2N+2 ,TP 2N+3 …TP 3N The side surfaces facing the +X direction will respectively generate reflected light having the color of the third color resist CR3 , for example, blue reflected light.

[0050] Similarly, when the user views the display panel 10 from the −X direction to the +X direction at a side viewing angle, the first signal lines TP1, TP2, TP3, TP4, TP5, TP6, TP7, TP8, TP9, TP10, TP11, TP2, TP3, TP4, TP50, TP12, TP13, TP14, TP15, TP16, TP17, TP NThe side surfaces facing the -X direction will respectively generate reflected light having the color of the first color resist CR1, for example, red reflected light; the second signal lines TP N+1 , TP N+2 , TP N+3 …TP 2N The side surfaces facing the -X direction will respectively generate reflected light having the color of the third color resist CR3, for example, blue reflected light; the third signal lines TP 2N+1 , TP 2N+2 ,TP 2N+3 …TP 3N The side surfaces facing the −X direction will respectively generate reflected light having the color of the second color resist CR2 , for example, green reflected light.

[0051] In some preferred embodiments, N is equal to M and is less than or equal to 30. When a user views the display panel 10 from the +X direction toward the -X direction at a lateral viewing angle, the green reflected light from the first region R1, the red reflected light from the second region R2, and the blue reflected light from the third region R3 are mixed to form white light.

Therefore, compared to Figure 1C The display panel shown in the embodiment will not have color difference at side viewing angles due to reflection of each signal line.

[0052] It should also be noted that there is no second signal line TP in the first region R1 of the display panel 10 of this embodiment. N+1 ,TP N+2 , TP N+3 …TP 2N and the third signal line TP 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N There are no first signal lines TP1, TP2, TP3…TP in the second region R2. N and the third signal line TP 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N There are no first signal lines TP1, TP2, TP3…TP in the third region R3. N and the second signal line TP N+1 , TP N+2 , TP N+3 …TP 2N Compared to Figure 2In the embodiment shown, signal lines TS1, TS2, TS3 are arranged under the black matrix BM at the junction of adjacent color resists CR1, CR2, CR3. m ,TS m+1 ...the situation, Figure 3 In the embodiment shown, the signal lines TP1 ...TP N , TP N+1 …TP 2N , TP 2N+1 …TP 3N The distribution density of the signal lines is reduced to one third. This can avoid the problem of dark state light leakage and the decrease in contrast of the front viewing angle / side viewing angle caused by the high distribution density of the signal lines. In some embodiments, Figure 3 The center (normal viewing angle) contrast ratio of the display panel is relatively high. Figure 2 The center contrast of the display panel in the XT is improved by 8%.

[0053] In some preferred embodiments, N is equal to M and less than or equal to 25. In some more preferred embodiments, N is equal to M and less than or equal to 20.

[0054] In some embodiments, N may be smaller than M. For example, M=20, N=10, and the first signal lines TP1, TP2, TP3, TP4, TP5, TP6, TP7, TP8, TP9, TP10, TP11, TP21, TP32, TP43, TP54, TP15, TP16, TP17, TP18, TP19, TP20, TP N The spacing between the adjacent second signal lines TP is the same. N+1 , TP N+2 , TP N+3 …TP 2N The spacing between the adjacent third signal lines TP is the same. 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N The spacing between the two is the same. This can still maintain no color difference in the lateral viewing angle, and further reduce the distribution density of the signal lines.

[0055] Reference Figure 1A as well as Figure 4 In the second embodiment of the present invention, the display panel 10 includes a plurality of pixel units PX arranged along the X direction and the Y direction, and each pixel unit PX includes a first color resist CR1, a second color resist CR2, and a third color resist CR3 arranged in sequence 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.

[0056] The display panel 10 further includes a plurality of signal lines TP i , each signal line TP iIn the Y direction, there are a plurality of first line segments SE1, a plurality of second line segments SE2 and a plurality of third line segments SE3. A fourth line segment SE4 is between the first line segment SE1 and the second line segment SE2, and a fifth line segment SE5 is between the second line segment SE2 and the third line segment SE3. The fourth line segment SE4 is parallel to the fifth line segment SE5.

[0057] Each first line segment SE1 corresponds to the intersection of N first color resistors CR1 and N second color resistors CR2, each second line segment SE2 corresponds to the intersection of N second color resistors CR2 and N third color resistors CR3, and each third line segment SE3 corresponds to the intersection of N third color resistors CR3 and N first color resistors CR1, where N is a positive integer. Since a first color resistor CR1, a second color resistor CR2, and a third color resistor CR3 have the same width in the Y direction, a first line segment SE1, a second line segment SE2, and a third line segment SE3 have the same length in the Y direction. In addition, each signal line TP i With respect to the virtual line C1, it has a symmetrical structure, such as Figure 4 shown.

[0058] Accordingly, when the user views the display panel 10 from the +X direction toward the -X direction at a side viewing angle, the side of the first line segment SE1 facing the +X direction will generate reflected light having the color of the second color resist CR2, such as green reflected light; the side of the second line segment SE2 facing the +X direction will generate reflected light having the color of the third color resist CR3, such as blue reflected light; and the side of the third line segment SE3 facing the +X direction will generate reflected light having the color of the first color resist CR1, such as red reflected light.

[0059] Similarly, when the user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the side of the first line segment SE1 facing the -X direction will generate reflected light having the color of the first color resist CR1, such as red reflected light; the side of the second line segment SE2 facing the -X direction will generate reflected light having the color of the second color resist CR2, such as green reflected light; and the side of the third line segment SE3 facing the -X direction will generate reflected light having the color of the third color resist CR3, such as blue reflected light.

[0060] In some preferred embodiments, N is less than or equal to 25. In some more preferred embodiments, N is less than or equal to 20. Accordingly, when a user views the display panel 10 from the +X direction toward the -X direction at a lateral viewing angle, the green reflected light from the first line segment SE1, the blue reflected light from the second line segment SE2, and the red reflected light from the third line segment SE3 are mixed to form white light. Similarly, when a user views the display panel 10 from the -X direction toward the +X direction at a lateral viewing angle, the red reflected light from the first line segment SE1, the green reflected light from the second line segment SE2, and the blue reflected light from the third line segment SE3 are mixed to form white light. Therefore, compared to Figure 1C The display panel shown in the embodiment will not have color difference at side viewing angles due to reflection of each signal line.

[0061] Furthermore, compared to Figure 2 Middle signal line TS1, TS2…TS m ,TS m+1 The distribution density of ... Figure 4 Medium signal line TP i The distribution density is low, which can avoid the problem of dark state light leakage and decreased contrast at front viewing angle / side viewing angle caused by too high distribution density of signal lines.

[0062] Also refer to Figure 4 , each signal line TP i It also includes a plurality of dummy line segments DL, and each signal line TP i The electrical signal on Figure 4 As shown in the arrow direction, there is no electrical signal on the dummy line segments DL. Since the fourth line segment SE4 is arranged between two adjacent second color resistors CR2, and the fifth line segment SE5 is arranged between two adjacent third color resistors CR3, by respectively arranging the dummy line segments DL between two adjacent first color resistors CR1, no color difference occurs when the user views the display panel 10 from the +Y direction to the -Y direction or from the -Y direction to the +Y direction.

[0063] Reference Figure 1A as well as Figure 5 In the third embodiment of the present invention, the display panel 10 includes a plurality of first signal lines TP1 and a plurality of second signal lines TP2. The color resist layer 300 includes a plurality of first color resists CR1, a plurality of second color resists CR2, and a plurality of third color resists CR3, wherein the colors of the first color resists CR1, the second color resists CR2, and the third color resists CR3 are different.

The first signal lines TP1 and the second signal lines TP2 are alternately arranged along the X direction, such as Figure 5 As shown. Moreover, in the X direction, the area between the adjacent first signal lines TP1 and the second signal lines TP2 corresponds to a plurality of second color resists CR2. Accordingly, when the user views the display panel 10 from the +X direction to the -X direction at a lateral viewing angle or from the -X direction to the +X direction at a lateral viewing angle, the side surfaces of the first signal lines TP1 will respectively generate reflected light having the color of the third color resist CR3, such as blue reflected light; and the side surfaces of the second signal lines TP2 will respectively generate reflected light having the color of the first color resist CR1, such as red reflected light. The blue reflected light from the first signal line TP1 and the red reflected light from the second signal line TP2 will be mixed to form purple light.

[0064] In this embodiment, a first color resist CR1, a second color resist CR2, a third color resist CR3, a third color resist CR3, a second color resist CR2, and a first color resist CR1 are sequentially arranged in the X direction, and the above arrangement is periodically repeated in the X direction. Accordingly, the distance between two adjacent first signal lines TP1 and second signal lines TP2 is a constant value. Therefore, when the user views the display panel 10 from a side viewing angle, the purple reflected light will be evenly distributed.

[0065] Reference Figure 1A as well as Figure 6In the fourth embodiment of the present invention, the display panel 10 includes a plurality of first signal lines TP1, a plurality of second signal lines TP2, and a plurality of third signal lines TP3. The color resist layer 300 includes a first color resist CR1, a plurality of second color resists CR2, and a plurality of third color resists CR3, wherein the colors of the first color resist CR1, the second color resist CR2, and the third color resist CR3 are different. Each first signal line TP1 corresponds to the boundary between the third color resists CR3 adjacent to each other, each second signal line TP2 corresponds to the boundary between the second color resists CR2 adjacent to each other, and each third signal line TP3 corresponds to the boundary between the first color resists CR1 adjacent to each other. The first signal line TP1, the second signal line TP2, and the third signal line TP3 are arranged in sequence along the X direction, and the above arrangement is repeated periodically along the X direction. In the X direction, the area between the adjacent first signal lines TP1 and the second signal lines TP2 corresponds to the plurality of first color resists CR1, and the area between the adjacent second signal lines TP2 and the third signal lines TP3 corresponds to the plurality of third color resists CR3. Accordingly, when the user views the display panel 10 from the +X direction to the -X direction at a lateral viewing angle or from the -X direction to the +X direction at a lateral viewing angle, the side surfaces of the first signal lines TP1 will respectively generate reflected light having the color of the third color resist CR3, such as blue reflected light; the side surfaces of the second signal lines TP2 will respectively generate reflected light having the color of the second color resist CR2, such as green reflected light; and the side surfaces of the third signal lines TP3 will respectively generate reflected light having the color of the first color resist CR1, such as red reflected light.
