Display panel and display device

A display panel, comprising:

• a substrate layer, wherein a plurality of sub-pixel structures are disposed on a side of the substrate layer;
• and
• a touch electrode layer disposed on a side of the sub-pixel structures away from the substrate layer, wherein the touch electrode layer comprises a plurality of first openings, and an orthographic projection of the first openings on the substrate layer covers an orthographic projection of the plurality of sub-pixel structures on the substrate layer;
• wherein,
• the touch electrode layer comprises a first electrode layer, a touch insulating layer, and a second electrode layer arranged in a stack, the touch insulating layer is disposed between the first electrode layer and the second electrode layer, and the second electrode layer is disposed on a side of the touch insulating layer away from the substrate layer;
• and
• an orthographic projection of the second electrode layer on the substrate layer covers an orthographic projection of the touch insulating layer on the substrate layer, and an edge of the orthographic projection of the second electrode layer on the substrate layer surrounds an edge of the orthographic projection of the touch insulating layer on the substrate layer, or an edge of the orthographic projection of the second electrode layer on the substrate layer at least partially overlaps with an edge of the orthographic projection of the touch insulating layer on the substrate layer.
