Abstract

Provided are a display panel and a display device. An array layer is located on a substrate. A display layer is located on a side of the array layer facing away from the substrate and includes light-emitting elements. A color filter layer is located on a side of the display layer facing away from the array layer. The color filter layer includes a light-blocking layer and color filters. The light-blocking layer includes first light-blocking portions. Each first light-blocking portion forms an imaging aperture. A protective layer is located on the color filter layer. Each first metal part overlaps the first light-blocking portion. The optical sensor layer is located on a side of the color filter layer facing away from the protective layer and configured to detect an image formed by the imaging aperture. Further provided is a display device including the preceding display panel.
