Abstract
A display panel and a display device. The display panel includes a display region and a non-display region including an encapsulation region, and an encapsulant is disposed in the encapsulation region between a dielectric layer and a cover plate opposite to each other. The dielectric layer in the encapsulation region includes N encapsulation sub-regions, in which a 1st encapsulation sub-region is closest to the display region among the encapsulation sub-regions, and an Nth encapsulation sub-region is farthest from the display region among the encapsulation sub-regions. A contact area between at least the first encapsulation sub-region and the encapsulant is smaller than the contact area between any other encapsulation sub-region and the encapsulant.
