The invention discloses a display panel and a display device. The display panel comprises a flexible substrate, and the flexible substrate comprises a display area and a bending area positioned on atleast one side of the display area. The part, positioned in the bending area, of the flexible substrate is bent towards one side far away from the light-emitting face of the display panel, a support module is arranged at the bending inner side of the bending area, a first surface of the support module is bonded to the flexible substrate through a first bonding layer, the first surface is an arc-shaped surface, the radius of the first surface is equal to the bending radius of the bent area, thus the bending radius of the bending area can be accurately controlled, then the excessive stretching when the flexible substrate is bent is prevented, meanwhile, the support module can carry out support protection on the bending area, so that the dead bending of the bending area is prevented, the linebreakage of the bending area is avoided, and the reliability of the display panel is improved.
