A display panel, comprising: 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 (h), 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 (h) 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; and 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; the slope portions comprise a first slope sub-portion and a second slope sub-portion, and the second slope sub-portion is located at a side of the first slope sub-portion toward the flat portion; characterized in that an average slope of the first slope sub-portion is greater than an average slope of the second slope sub-portion. 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 (h), 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 (h) 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; and 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; the slope portions comprise a first slope sub-portion and a second slope sub-portion, and the second slope sub-portion is located at a side of the first slope sub-portion toward the flat portion; characterized in that an average slope of the first slope sub-portion is greater than an average slope of the second slope sub-portion.
