Abstract
A display panel and a display device are provided. The display panel includes a flexible screen body having a first region and a second region. The second region has a bending transitional region coplanar with the first region, a bending region, and an extending region connected in sequence. The first region is connected to the bending region through the bending transitional region and is at least a part of an active region. The bending region and the extending region are at least a part of a non-active region and not coplanar with the first region. The bending transitional region is another part of the active region or another part of the non-active region. The display panel further includes a buffer layer disposed on surfaces of the bending transitional region and the bending region at a stress concentration side thereof. At least two sections of the buffer layer have different hardnesses.
