1. 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; and
an organic structure comprising an organic slope portion and an organic flat portion,
wherein the organic structure is at least partially located in the peripheral region,
the organic slope portion comprises a first slope sub-portion and a second slope sub-portion, and the second slope sub-portion is located on a side of the first slope sub-portion facing the organic flat portion; and
an average slope degree of the first slope sub-portion is greater than an average slope degree of the second slope sub-portion.
