The invention provides a display panel and a display device, and the display panel comprises a photosensitive area, a substrate, a light-emitting layer, and a light blocking layer. A semiconductor layer is arranged on one side of the substrate and comprises a plurality of semiconductor elements, and the semiconductor elements comprise first semiconductor elements located in the photosensitive area. The light-emitting layer is located on the side, away from the substrate, of the semiconductor layer, the light blocking layer is located on the side, away from the light-emitting layer, of the semiconductor layer, the light blocking layer comprises a plurality of first light blocking parts arranged at intervals, and the first light blocking parts correspond to the first semiconductor elements. The orthographic projection of the first light blocking part on the plane where the substrate is located is at least partially overlapped with the orthographic projection of the first semiconductor element on the plane where
