1. A display panel comprising: an active area, a peripheral area located at a periphery of the active area; wherein
the active area comprises a base substrate, a display structure layer and a touch structure layer arranged sequentially on the base substrate;
the peripheral area comprises an isolation dam, a first ground trace and a second ground trace arranged on the base substrate; and
the first ground trace is located on a side of the isolation dam close to the active area, and the second ground trace is located on a side of the isolation dam away from the active area,
wherein the touch structure layer comprises: a first touch conductive layer, a first touch insulating layer, a second touch conductive layer, and a second touch insulating layer arranged sequentially on the display structure layer; and
the first ground trace and the second ground trace are of a structure of a same layer as the second touch conductive layer,
wherein an orthographic projection of the second touch insulating layer on the base substrate partially overlaps an orthographic projection of the second ground trace on the base substrate.
