Flexible display panel and display device

The invention relates to a flexible display panel and a display device. The display panel comprises a first film, a second film, a first area and a second area, the elastic modulus of the first film is larger than that of the second film in the first area, and the elastic modulus of the first film is smaller than that of the second film in the second area. When the flexible display panel is bent,the positions of the first film and the second film in the display panel are different, and the first film and the second film are different in deformation during bending. Therefore, bending stress applied to the first film and the second film with corresponding different elastic modulus is balanced, the bending property of the flexible display panel is improved, and the flexible display panel canbear a smaller bending radius.
