Abstract
Provided are a display panel and a display device. The display panel includes a fingerprint identification module, a light-blocking layer, a light-emitting device layer and a touch function layer which are sequentially stacked, where the light-blocking layer includes a plurality of imaging apertures; and the touch function layer includes a plurality of first touch areas and a plurality of second touch areas. The plurality of first touch areas do not overlap with imaging aperture identification areas, and the plurality of second touch areas overlap with at least one of the imaging aperture identification areas. Reflectivity of the second touch area is smaller than reflectivity of the first touch area; or transmittance of the second touch area is greater than transmittance of the first touch area; or light transmission uniformity of the second touch area is greater than light transmission uniformity of the first touch area.
