Abstract
The present application provides a display panel and a display device. The display panel includes a display area, a hole-digging area, and a buffer area between the display area and the hole-digging area, wherein one or more retaining walls on the pixel defining layer in the buffer area, a top surface of the retaining wall is provided with a groove or a protrusion; the encapsulating layer is disposed on the light-emitting functional layer and the retaining wall, such that a contact area between a top surface of the retaining wall and the encapsulation layer is increased, thus avoiding the problem of film peeling between the retaining wall and the encapsulating layer.
