Abstract
A display panel and a display device are provided. An adhesive layer is disposed between an organic layer and an inorganic layer in a bonding area of the display panel, where a surface roughness of an adhesive layer material is greater than a surface roughness of an organic layer material and a surface roughness of an inorganic layer material. In addition, a plurality of concave-convex structures can be provided on a surface of the organic layer and/or a surface of the inorganic layer in contact with the adhesive layer to enhance interface bonding force. This can alleviate a problem that film layers are prone to peeling off when a flexible printed circuit (FPC) is bonded to the display panel in the prior art.
