Display panel and display device

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, and at least one second trace sub-portion having an average width of a second width, wherein the first width is less than the second width;
• 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;
• 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 and an average slope of the first slope sub-portion is greater than an average slope of the second slope sub-portion;
• a side of the second trace sub-portion close to the first trace sub-portion has a width gradient;
• and the width of the second trace sub-portion gradually decreases in a direction from the second trace sub-portion to the first trace sub-portion;
• and
• an edge of the orthographic projection of the first dam portion on the base substrate overlaps with an orthographic projection of the first trace sub-portion on the base substrate.

• and
• a range of a ratio of the minimum distance between the 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 to a width of the first dam portion is less than 0.5 and greater than or equal to 0.
