Claim 16:
17. A display device, comprising a display panel, wherein the display panel comprises:
a base substrate, having a display region and a peripheral region surrounding the display region;
a dam structure, disposed on the base substrate and located in the peripheral region, surrounding the display region, and comprising a first dam portion located at at least one side of the display region;
a touch electrode, at least located in the display region; and
a touch trace, electrically connected with the touch electrode, and disposed on a side of the dam structure away from the base substrate;
wherein the touch trace comprises a first trace portion, and an orthographic projection of at least a part of the first trace portion on the base substrate overlaps with an orthographic projection of the first dam portion on the base substrate;
the first trace portion comprises at least one first trace sub-portion having an average width of a first width, and at least one second trace sub-portion having an average width of a second width;
in an extending direction of the first trace portion, a minimum distance between an orthographic projection of the first trace sub-portion on the base substrate and the orthographic projection of the first dam portion on the base substrate is less than or equal to 15 μm; and
the first width is less than the second width,
wherein in a direction along the extending direction of the first trace portion, the first dam portion comprises a flat portion and slope portions located at both sides of the flat portion,
wherein an orthographic projection of the slope portion on the base substrate overlaps with the orthographic projection of the first trace sub-portion on the base substrate
wherein the slope portions comprise a first slope sub-portion and a second slope sub-portion, and
wherein the second slope sub-portion is located at a side of the first slope sub-portion toward the flat portion and an average slope of the first slope sub-portion is greater than an average slope of the second slope sub-portion.
