Abstract
A display panel and a display device are provided, which including a folding area configured to bend the display panel. The display panel further comprising a film layer. The film layer is disposed in the folding area, and the film layer includes a metal layer. A stress balance line is provided in the film layer. When the folding area is bent, the stress balance line is a curve having an upper boundary and a lower boundary. A resultant force of tensile stress and compressive stress at any point on the stress balance line is zero. The metal layer is disposed between the upper boundary and the lower boundary of the stress balance line.
