Touch display panel and display device

A touch display panel, comprising:

• a display substrate, a touch circuit on a side of a light emergent surface of the display substrate, and a first optical adhesive between the display substrate and the touch circuit, wherein a rough contact surface existing on a part, in a frame region, of the first optical adhesive, and the touch circuit comprises a plurality of touch traces insulated from one another and located in the frame region;
• and
• each of the touch traces is arranged to be stacked, and an orthographic projection of each of the touch traces on the display substrate covers an orthographic projection of a part, located in the frame region, of the first optical adhesive on the display substrate;
• wherein the touch traces are respectively located on two layers, and an orthographic projection of each of the touch traces on the first layer on the display substrate is provided with a region overlapped with an orthographic projection of each of the touch traces on the second layer on the display substrate.
