Abstract

A display panel and a display device are provided. The display panel includes: a display region and a non-display region surrounding the display region; multiple gate lines; and multiple data lines. The gate lines include regular gate lines and irregular gate lines. In the display region, the regular gate lines and the irregular gate lines are extended in a first direction, and a length of a part of the regular gate line in the display region is greater than a length of a part of the irregular gate line in the display region. The data lines include regular data lines and irregular data lines, and an extension direction of the regular data lines and the irregular data lines intersects with the first direction.

Claims

1. A display panel, comprising:

a display region;

a non-display region surrounding the display region;

a plurality of gate lines, wherein the plurality of gate lines comprises a plurality of regular gate lines and a plurality of irregular gate lines;

in the display region, the plurality of regular gate lines and the plurality of irregular gate lines are both extended in a first direction, and a length of each of the plurality of regular gate lines in the display region is greater than a length of each of the irregular gate lines in the display region; and

a plurality of data lines, wherein the data lines comprise a plurality of regular data lines and a plurality of irregular data lines, an extension direction of the plurality of regular data lines and the plurality of irregular data lines intersects with the first direction,

wherein in the display region, the number of the plurality of gate lines that intersect with the plurality of regular data lines in an insulating manner is greater than the number of the plurality of gate lines that intersect with the irregular data lines in an insulating manner; and

in the non-display region, at least one of the plurality of irregular data lines intersects with the plurality of irregular gate lines in an insulating manner.

2. The display panel according to claim 1, wherein a length of one of the plurality of regular data lines in the display region is greater than a length of one of the plurality of irregular data lines in the display region.

3. The display panel according to claim 1, wherein each of the plurality of irregular data lines and each of the plurality of irregular gate lines intersect in an insulating manner.

4. The display panel according to claim 1, wherein

in the display region, one of the plurality of regular data lines intersects with a number of the plurality of gate lines in an insulating manner, wherein the number is N;

and

one of the plurality of irregular data lines intersects with another number of the plurality of gate lines in an insulating manner in the display region, wherein the another number is X, and intersects with N less X (N−

X) of the plurality of irregular gate lines in an insulating manner in the non-display region, wherein both X and N are positive integers and X<

N.

5. The display panel according to claim 1, further comprising a semiconductor active layer, a source drain metal layer, and a gate metal layer, wherein

the plurality of gate lines are located in the gate metal layer, and a subset of the plurality of regular data lines and a subset of the plurality of irregular data lines in the display region are located in the source drain metal layer.

6. The display panel according to claim 5,
