Display panel and display device

1. A display panel, comprising: a display area and a non-display area adjacent to the display area, wherein the display area includes: a first display area and a second display area;

the first display area and the second display area comprise a plurality of pixels arranged in an array, a plurality of data lines extending in a column direction and arranged in a row direction, and a plurality of fixed potential signal lines extending in the column direction and arranged in the row direction, with the row direction being perpendicular to the column direction; the data lines and the fixed potential signal lines are arranged in a same layer, and a quantity of pixels in each column of pixels in the first display area is less than that of pixels in any column of pixels in the second display area; and

the first display area further comprises compensation lines, wherein the compensation line and the fixed potential signal lines are electrically connected and arranged in different layers, the compensation lines and the data lines are insulated from each other, and there is an overlapping area between each of the compensation lines and each of the data lines in a direction perpendicular to the display panel;

wherein the first display area comprises at least a first column of pixels and a second column of pixels with different quantity of pixels, and a quantity of pixels in the first column of pixels is less than a quantity of pixels in the second column of pixels;

there is a first overlapping area between a data line and a compensation line corresponding to the first column of pixels, and there is a second overlapping area between a data line and a compensation line corresponding to the second column of pixels; and

the first overlapping area is larger than the second overlapping area.

2. The display panel of claim 1 , wherein when all compensation lines in the column direction have a same length, a width of the compensation lines in the row direction in the first overlapping area is larger than that of the compensation lines in the row direction in the second overlapping area.

3. The display panel of claim 1 , wherein when all compensation lines in the row direction have a same width, a length of the compensation lines in the column direction in the first overlapping area is longer than that of the compensation lines in the column direction in the second overlapping area.

4. The display panel of claim 1 , wherein a width of the data line in the row direction in the first overlapping area is larger than that of the data line in the row direction in the second overlapping area.

5. The display panel of claim 3 , wherein a width of the data line in a non-overlapping area is less than that of the data line in the overlapping area.

6. The display panel of the claim 1 , wherein an insulating layer is arranged between a layer where the compensation lines are located and a layer where the data lines are located; and

each of the compensation lines is connected with a corresponding fixed potential signal line through a through-hole in the insulating layer.

7. The display panel of the claim 1 , wherein the fixed potential signal lines include a power supply voltage signal line.

8. The display panel of claim 1 , wherein at least part of an edge of the first display area is a curved edge, a fillet, a chamfer or a notch, and the columns of pixels in the first display area extend to the curved edge, the fillet, the chamfer or the notch.

9. A display device, comprising the display panel in the claim 1 .

10. The display device of claim 9 , wherein when all compensation lines in the column direction have a same length, a width of the compensation lines in the row direction in the first overlapping area is larger than that of the compensation lines in the row direction in the second overlapping area.

11. The display device of claim 9 , wherein when all compensation lines in the row direction have a same width, a length of the compensation lines in the column direction in the first overlapping area is longer than that of the compensation lines in the column direction in the second overlapping area.

12. The display device of claim 9 , wherein a width of the data line in the row direction in the first overlapping area is larger than that of the data line in the row direction in the second overlapping area.

13. The display device of claim 11 , wherein a width of the data line in a non-overlapping area is less than that of the data line in the overlapping area.

14. The display device of the claim 9 , wherein an insulating layer is arranged between a layer where the compensation lines are located and a layer where the data lines are located; and

each of the compensation lines is connected with a corresponding fixed potential signal line through a through-hole in the insulating layer.

15. The display device of the claim 9 , wherein the fixed potential signal lines include a power supply voltage signal line.

16. The display device of claim 9 , wherein at least part of an edge of the first display area is a curved edge, a fillet, a chamfer or a notch, and the columns of pixels in the first display area extend to the curved edge, the fillet, the chamfer or the notch.
