The invention discloses a touch display panel and a display device. The touch display panel comprises a display substrate, a touch module located on one side of the light emitting face of the displaysubstrate and first optical cement located between the display substrate and the touch module, and the portion, located in a frame area, of the first optical cement is provided with a rough contact face. The touch module comprises a plurality of touch wires which are located in the frame area and insulated from one another. The touch wires are arranged in a stacked mode, and the orthographic projection of each touch wire on the display substrate completely covers the orthographic projection of the portion, located in the frame area, of the first optical cement on the display substrate. According to the touch display panel, the touch wires are arranged in the stacked mode, the touch wires completely cover the part, in the frame area, of the first optical cement, diffuse reflection light caused by existence of the rough surface can be shielded, and therefore the light leakage phenomenon of the touch display panel can be effectively avoided.
