Abstract
Provided are a display panel and a display device. The display panel includes a display assembly and a fingerprint recognition assembly. The display assembly includes a base substrate, a plurality of pixel units disposed on one side of the base substrate and a first scanning line extending along a first direction, each of the plurality of pixel units includes a pixel driving unit and a light-emitting unit disposed on one side of the pixel driving unit facing away from the base substrate, and the light-emitting unit includes a metal anode. The fingerprint recognition assembly is configured to perform fingerprint recognition according to light reflected by a touch object to a fingerprint recognition unit. A vertical projection of the first scanning line on the base substrate and a vertical projection of the metal anode on the base substrate have an overlapping area.
