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;
an organic structure at least partially located in the peripheral region, the organic structure comprises a dam, the dam at least partially surrounds the display region, and the dam comprises a first dam portion located on at least one side of the display region; the first dam portion comprises a plurality of sub-dams arranged at intervals in a direction facing away from the display region; and
a shielding structure, wherein an orthographic projection of the shielding structure on the base substrate at least partially overlaps with an orthographic projection of at least one of the plurality of sub-dams on the base substrate;
the shielding structure comprises a first shielding structure and a second shielding structure, and a height of the first shielding structure relative to the first surface is greater than a height of the second shielding structure relative to the first surface; and
a boundary line between the first height portion and the second height portion at least partially overlaps with the first shielding structure in a direction perpendicular to the first surface.
