A display panel, comprising a display region and a peripheral region surrounding the display region, and further comprising:

• a base substrate;
• a driving circuit layer, provided on the base substrate;
• a display structure layer, provided on a side of the driving circuit layer facing away from the base substrate;
• an encapsulation layer, provided on a side of the display structure layer facing away from the base substrate;
• a touch electrode, provided on a side of the encapsulation layer facing away from the base substrate, and at least located in the display region;
• a touch wire, provided on the side of the encapsulation layer facing away from the base substrate, and electrically connected to the touch electrode, wherein the touch wire comprises a first sub-portion and a second sub-portion electrically connected to the first sub-portion, a main surface of the base substrate close to the touch wire is a first surface, and a distance between the first sub-portion and the first surface is smaller than a distance between the second sub-portion and the first surface;
• the second sub-portion comprises a first height portion and a second height portion electrically connected to the first height portion, the first height portion is located between the first sub-portion and the second height portion, a height of the first height portion relative to the first surface is smaller than a height of the second height portion relative to the first surface, line widths of respective positions of the first height portion are inversely proportional to heights of the respective positions of the first height portion relative to the first surface, and line widths of respective positions of at least part of the second height portion are proportional to heights of the respective positions of the at least part of the second height portion relative to the first surface, wherein
• the touch wire further comprises a first sub-wiring layer and a second sub-wiring layer located on a side of the first sub-wiring layer facing away from the base substrate;
• the display panel further comprises a touch insulating layer, the touch insulating layer is between the first sub-wiring layer and the second sub-wiring layer, the touch insulating layer comprises a via hole, and the first sub-wiring layer is electrically connected to the second sub-wiring layer through the via hole;
• the via hole at least partially overlaps with the first dam portion in a direction perpendicular to the first surface;
• and
• an orthographic projection of the via hole on the base substrate is located within an orthographic projection of the second height portion on the base substrate.
