摘要： A display panel (000) and a display device are provided. The display panel (000) includes: a substrate (100), and a plurality of first light-emitting devices (200), a plurality of first pixel driving circuits (300) and a plurality of first signal lines (400), which are disposed on the substrate (100). As only the first light-emitting devices (200) are disposed in a light-transmitting region (101a) of the substrate (100), the first pixel driving circuits (300) electrically connected with the first light-emitting devices (200) are disposed in a non-light-transmitting region, and the first signal lines (400) electrically connected with the first pixel driving circuits (300) are disposed outside the light-transmitting region (101a). The light transmittance of the light-transmitting region (101a) in the substrate (100) is relatively high. When the display panel (000) is integrated in the display device, it can be ensured that a photosensitive sensor (001) in the display device has a better performance in the case where the screen-to-body ratio of the display device is relatively high.
