The drains of the second thin-film transistor 440 and the third thin-film transistor 450 are electrically connected to the sub-pixel electrode 420. The main pixel electrode 410 includes a first main electrode 411, and the sub-pixel electrode 420 includes a second main electrode 421. The extending directions of the first main electrode 411 and the second main electrode 421 are the same as that of the data line 200. A part of the common electrode line 460 is provided with a slot 4612; in a top view of the display panel, a part of the shared electrode line 300 overlaps with the first main electrode 411 and the second main electrode 421, and at least a part of at least one of the shared electrode line 300 overlapping with the first main electrode 411 and the shared electrode line 300 overlapping with the second main electrode 421 is located in the slot 4612; specifically, the common electrode line 460 includes a first line segment 461, the extending direction of the first line segment 461 is the same as that of the data line 200, and the slot 4612 is located on the first line segment 461, wherein at least a part of the shared electrode line 300 overlapping with the first main electrode 411 is located in the slot 4612.

[0045] The liquid crystal display panel of the conventional solution is provided with a common electrode line 300, and the common electrode line 300 is electrically connected to the thin film transistor, so as to adjust the deflection angle of the liquid crystal of the liquid crystal display panel through the voltage of the common electrode line 300, thereby improving the large viewing angle of the liquid crystal display panel. When the main electrode of the pixel 400 electrode of the liquid crystal display panel and the film layer of the common electrode line 300 are damaged or there are foreign objects, the common electrode line 300 of the liquid crystal display panel is conducted with the pixel 400 electrode. Since the voltage input to the common electrode line 300 is greater than the voltage input to the data line 200, a pressure difference is formed between the common electrode line 300 and the electrode on the opposite substrate side, causing bright spots to appear at the positions of the common electrode line 300 and the pixel 400 electrode of the display panel. Since the common electrode line 460 is located below the pixel 400 electrode and the common electrode line 300, the common electrode line 460 blocks the bright spots, resulting in an increase in the difficulty of repairing the brightness of the display panel. Therefore, the technical solution of the present application is to set the display panel to include a common electrode line 300 and a pixel 400.

After the array substrate and the opposite substrate of the display panel are laminated, the position of the bright spot can be found from the backlight side of the display panel, so as to facilitate the repair of the bright spot of the display panel, thereby reducing the difficulty of repairing the bright spot of the display panel.

Among them, the main pixel region and the sub-pixel region of a single pixel 400 include eight display domain regions.

[0047] In this embodiment, the top view of the display panel is a view seen from the back side of the display panel looking upward.

[0048] In this embodiment, the side view of the display panel is a view seen from the light-emitting side of the display panel looking downward.

[0049] In this embodiment, refer to Figure 1 , the common electrode line 460 further includes a second line segment 462, and the second line segment 462 is connected to the first line segment 461. Among them, the extending direction of the second line segment 462 is the same as the extending direction of the scanning line.

[0050] In this embodiment, refer to Figure 1 , in the top view of the display panel, a part of the shared electrode line 300 overlapping with the first main electrode 411 is located in the slot 4612, and another part of the shared electrode line 300 overlapping with the first main electrode 411 overlaps with the first line segment 461. By setting that in the top view of the display panel, a part of the shared electrode line 300 overlapping with the first main electrode 411 is located in the slot 4612, and another part of the shared electrode line 300 overlapping with the first main electrode 411 overlaps with the first line segment 461, on the one hand, it can reduce the occlusion of the shared electrode line 300 by the region of the main pixel electrode 410. After laminating the array substrate and the counter substrate of the display panel, the position of the bright point can be found from the backlight side of the display panel, so as to facilitate repairing the bright point of the display panel, thereby reducing the difficulty of repairing the bright point of the display panel. On the other hand, it is not necessary to set the width of the slot 4612 too large, reducing the risk of foreign objects entering the slot 4612 and avoiding the problem of poor bright points of the display panel caused by foreign objects entering the slot 4612 and electrically connecting the first main electrode 411 and the shared electrode line 300; at the same time, it is beneficial to reduce the width of the common electrode line 460 and improve the transmittance of the display panel.

[0051] In this embodiment, in the top view of the display panel, the shared electrode line 300 overlapping with the first main electrode 411 is located within the slot 4612.

[0052] In this embodiment, referring to Figure 2 , the first line segment 461 includes two first sub-segments 4611. The two first sub-segments 4611 are arranged side by side, and the extending direction of the first sub-segment 4611 is the same as the extending direction of the data line 200. The slot 4612 is formed between the two first sub-segments 4611.

[0053] In this embodiment, the sum of the widths of the two first sub-segments 4611 is not less than the width of the slot 4612. By setting the sum of the widths of the two first sub-segments 4611 to be not less than the width of the slot 4612, the strength of the first line segment 461 can be improved, the risk of breakage of the first line segment 461 can be reduced, and thus the display stability of the display panel can be improved.

One end of the second sub-segment 4613 is connected to one of the first sub-segments 4611, and the other end of the second sub-segment 4613 is connected to the other first sub-segment 4611. Since the slot 4612 is provided in the first line segment 461, the risk of breakage of the first line segment 461 is increased. Therefore, by setting that the first line segment 461 further includes a plurality of second sub-segments 4613, the plurality of second sub-segments 4613 are arranged at intervals, one end of the second sub-segment 4613 is connected to one of the first sub-segments 4611, and the other end of the second sub-segment 4613 is connected to the other first sub-segment 4611, the strength of the first line segment 461 can be improved, the risk of breakage of the first line segment 461 can be reduced, and thus the display stability of the display panel can be improved.

[0055] In this embodiment, the width of the slot 4612 is greater than the width of the shared electrode line 300, and the width of the slot 4612 is less than the width of the first main electrode 411 or the second main electrode 421. By setting the width of the slot 4612 to be greater than the width of the shared electrode line 300 and the width of the slot 4612 to be less than the width of the first main electrode 411 or the second main electrode 421, on the one hand, the common electrode will not block the lateral area of the shared electrode line 300, which is more conducive to finding the position of the bright point from the backlight side of the display panel, so as to facilitate repairing the bright point of the display panel, thereby reducing the difficulty of repairing the bright point of the display panel. On the other hand, it avoids the reduction of the transmittance of the display panel caused by the excessive width of the common electrode line 460.

Since the voltage input to the common electrode line 300 is greater than the voltage input to the data line 200, a pressure difference is formed between the common electrode line 300 and the electrode on the counter substrate side, resulting in bright spots at the positions of the common electrode line 300 and the pixel 400 electrode of the display panel. Since the common electrode line 460 is located below the pixel 400 electrode and the common electrode line 300, the common electrode line 460 blocks the bright spots, increasing the difficulty of repairing the brightness of the display panel.

By setting the sum of the widths of the two first sub-segments 4611 to be not less than the width of the slot 4612, the strength of the first segment 461 can be improved, the risk of the first segment 461 breaking can be reduced, and thus the display stability of the display panel can be improved.

[0067] In this embodiment, referring to Figure 6, the first line segment 461 further includes a plurality of second sub-segments 4613, the plurality of second sub-segments 4613 are arranged at intervals, one end of the second sub-segment 4613 is connected to one of the first sub-segments 4611, and the other end of the second sub-segment 4613 is connected to another first sub-segment 4611. Since the slot 4612 is provided in the first line segment 461, the risk of breakage of the first line segment 461 is increased. Therefore, by providing that the first line segment 461 further includes a plurality of second sub-segments 4613, the plurality of second sub-segments 4613 are arranged at intervals, one end of the second sub-segment 4613 is connected to one of the first sub-segments 4611, and the other end of the second sub-segment 4613 is connected to another first sub-segment 4611, the strength of the first line segment 461 can be improved, the risk of breakage of the first line segment 461 can be reduced, and thus the display stability of the display panel can be improved.

[0068] In this embodiment, the width of the slot 4612 is greater than the width of the shared electrode line 300, and the width of the slot 4612 is less than the width of the first main electrode 411 or the second main electrode 421. By setting the width of the slot 4612 to be greater than the width of the shared electrode line 300 and the width of the slot 4612 to be less than the width of the first main electrode 411 or the second main electrode 421, on the one hand, the common electrode will not block the lateral area of the shared electrode line 300, which is more conducive to finding the position of the bright point from the backlight side of the display panel, so as to facilitate repairing the bright point of the display panel, thereby reducing the difficulty of repairing the bright point of the display panel. On the other hand, it is avoided that the width of the common electrode line 460 is too large, resulting in a decrease in the transmittance of the display panel.

[0069] In this embodiment, refer to Figure 13, the display panel further includes a substrate 101, a first metal layer 102, a transparent insulating layer 103, a second metal layer 104, and a pixel electrode layer 105. The first metal layer 102 is disposed on the substrate 101, and the common electrode line 460 is located on the first metal layer 102.

The second metal layer 104 is disposed on a side of the first metal layer 102 away from the substrate 101, and the shared electrode line 300 is located on the second metal layer 104. The pixel electrode layer 105 is disposed on a side of the second metal layer 104 away from the substrate 101, and the main pixel electrode 410 and the sub-pixel electrode 420 are located on the pixel electrode layer 105. By disposing the transparent insulating layer 103 on a surface of the first metal layer 102 away from the substrate 101 and filling a part of the transparent insulating layer 103 into the slot 4612, on the one hand, the transparent filling layer can fill the slot 4612, thereby reducing the risk of breakage of the first line segment 461. On the other hand, the transparent filling layer will not block the electrode line, ensuring the position of the bright spot can be found from the backlight side of the display panel, so as to facilitate the repair of the bright spot of the display panel, thereby reducing the difficulty of repairing the bright spot of the display panel.

[0070] The third embodiment of the present application provides a third display panel. Refer to Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , the third embodiment is similar to the first embodiment. The difference between the third embodiment and the first embodiment is that at least a part of the shared electrode line 300 overlapping with the first main electrode 411 is located in the slot 4612, and at least a part of the shared electrode line 300 overlapping with the second main electrode 421 is located in the slot 4612.

[0071] The liquid crystal display panel of the conventional solution is provided with a common electrode line 300, and the common electrode line 300 is electrically connected to the thin film transistor, so as to adjust the deflection angle of the liquid crystal of the liquid crystal display panel through the voltage of the common electrode line 300, thereby improving the large viewing angle of the liquid crystal display panel. When the main electrode of the pixel 400 electrode of the liquid crystal display panel and the film layer of the common electrode line 300 are damaged or there are foreign objects, the common electrode line 300 of the liquid crystal display panel is conducted with the pixel 400 electrode. Since the voltage input to the common electrode line 300 is greater than the voltage input to the data line 200, a pressure difference is formed between the common electrode line 300 and the electrode on the opposite substrate side, causing bright spots to appear at the positions of the common electrode line 300 and the pixel 400 electrode of the display panel. Since the common electrode line 460 is located below the pixel 400 electrode and the common electrode line 300, the common electrode line 460 blocks the bright spots, resulting in an increase in the difficulty of repairing the brightness of the display panel. By providing that the display panel includes a common electrode line 300 and a pixel 400, the pixel 400 includes a main pixel electrode 410, a sub-pixel electrode 420 and a common electrode line 460, the main pixel electrode 410 includes a first main electrode 411, the sub-pixel electrode 420 includes a second main electrode 421, the extending directions of the first main electrode 411 and the second main electrode 421 are the same as the extending direction of the data line 200, a slot 4612 is provided in a part of the common electrode line 460, a part of the common electrode line 300 overlaps with the first main electrode 411 and the second main electrode 421, and at least a part of at least one of the common electrode line 300 overlapping with the first main electrode 411 and the common electrode line 300 overlapping with the second main electrode 421 is located in the slot 4612, the common electrode line 460 includes a first line segment 461, the extending direction of the first line segment 461 is the same as the extending direction of the data line 200, the slot 4612 is located on the first line segment 461, wherein at least a part of the common electrode line 300 overlapping with the first main electrode 411 is located in the slot 4612, and at least a part of the common electrode line 300 overlapping with the second main electrode 421 is located in the slot 4612; it is possible to reduce the shielding of the common electrode line 460 in the regions of the main pixel electrode 410 and the sub-pixel electrode 420 from the common electrode line 300. After the array substrate and the opposite substrate of the display panel are laminated, the position of the bright spot can be found from the backlight side of the display panel, so as to facilitate the repair of the bright spot of the display panel, thereby reducing the difficulty of repairing the bright spot of the display panel.

[0072] In this embodiment, referring to Figure 11 、 Figure 12, the main pixel electrode 410 further includes a third main electrode 412, the sub-pixel electrode 420 further includes a fourth main electrode 422, the extending direction of the third main electrode 412 is the same as that of the scanning line, the extending direction of the fourth main electrode 422 is the same as that of the scanning line, the third main electrode 412 intersects with the first main electrode 411 to divide the main pixel electrode 410 into four display domain regions, the fourth main electrode 422 intersects with the second main electrode 421 to divide the sub-pixel electrode 420 into four display domain regions, the region corresponding to the main pixel electrode 410 is the main pixel region, and the region where the sub-pixel electrode 420 is located is the sub-pixel region. Among them, the main pixel region and the sub-pixel region of a single pixel 400 include eight display domain regions.

[0076] In this embodiment, referring to Figure 4, in the top view of the display panel, a part of the shared electrode line 300 overlapping with the first main electrode 411 is located within the slot 4612, another part of the shared electrode line 300 overlapping with the first main electrode 411 overlaps with the first line segment 461, a part of the shared electrode line 300 overlapping with the second main electrode 421 is located within the slot 4612, and another part of the shared electrode line 300 overlapping with the second main electrode 421 overlaps with the first line segment 461.

On the one hand, it can reduce the occlusion of the common electrode line 460 of the main pixel electrode 410 region and the sub-pixel electrode 420 region on the shared electrode line 300. After laminating the array substrate and the counter substrate of the display panel, the position of the bright spot can be found from the backlight side of the display panel, so as to facilitate repairing the bright spot of the display panel, thereby reducing the difficulty of repairing the bright spot of the display panel. On the other hand, it is not necessary to set the width of the slot 4612 too large, reducing the risk of foreign objects entering the slot 4612 and avoiding the problem of poor bright spots of the display panel caused by foreign objects entering the slot 4612 and electrically connecting the first main electrode 411, the second main electrode 421 and the shared electrode line 300; at the same time, it is beneficial to reduce the width of the common electrode line 460 and improve the transmittance of the display panel.

[0077] In this embodiment, in the top view of the display panel, the shared electrode line 300 overlapping with the first main electrode 411 is located within the slot 4612, and the shared electrode line 300 overlapping with the second main electrode 421 is located within the slot 4612.

[0079] In this embodiment, the sum of the widths of the two first sub-segments 4611 is not less than the width of the slot 4612. By setting the sum of the widths of the two first sub-segments 4611 to be not less than the width of the slot 4612, the strength of the first line segment 461 can be improved, the risk of breakage of the first line segment 461 can be reduced, and thus the display stability of the display panel can be improved.

[0080] In this embodiment, referring to Figure 8 , the first line segment 461 further includes a plurality of second sub-segments 4613, the plurality of second sub-segments 4613 are arranged at intervals, one end of the second sub-segment 4613 is connected to one of the first sub-segments 4611, and the other end of the second sub-segment 4613 is connected to the other first sub-segment 4611. Since the slot 4612 is provided in the first line segment 461, the risk of breakage of the first line segment 461 will increase. Therefore, by setting that the first line segment 461 further includes a plurality of second sub-segments 4613, the plurality of second sub-segments 4613 are arranged at intervals, one end of the second sub-segment 4613 is connected to one of the first sub-segments 4611, and the other end of the second sub-segment 4613 is connected to the other first sub-segment 4611, the strength of the first line segment 461 can be improved, the risk of breakage of the first line segment 461 can be reduced, and thus the display stability of the display panel can be improved.

On the other hand, it is avoided that the width of the common electrode line 460 is too large, resulting in a reduction in the transmittance of the display panel.
