Display panel and display device

The invention discloses a display panel and a display device, the display panel comprises an array substrate, a chip on film flexible packaging substrate, a touch panel and a viscous layer, the array substrate comprises a binding area and a first area; one end of the chip on film is arranged in the binding area and is fixed with the binding area; the touch panel is formed on the array substrate and covers the part, located in the binding area, of the chip on film; the viscous layer is located among the touch panel, the array substrate and the chip on film, the viscous layer comprises a first viscous area opposite to the binding area and a second viscous area opposite to the first area, the first viscous area comprises a deformation space, and the first viscous area can extend into the deformation space after being extruded, so after the viscous layer is extruded, the thickness of the first viscous area is smaller than that of the second viscous area. According to the display panel, the binding area in the arr
