Abstract
A display panel and a display device. The display panel includes a substrate, at least three different light-emitting units disposed on the substrate, and at least three different buffer encapsulation layers disposed on the side of the at least three different light-emitting units facing away from the substrate. The at least three different light-emitting units emit at least three different colors. The thickness of at least one buffer encapsulation layer corresponding to at least one light-emitting unit among the at least three different light-emitting units is different from the respective thicknesses of the other buffer encapsulation layers corresponding to the other light-emitting units among the at least three different light-emitting units.
