Abstract
The present application discloses a display panel and a display device. The display panel includes substrate, a plurality of pixel driving circuits, and a light-shielding layer. By disposing the light-shielding layer in a transition display region of the display panel, disposing the light-shielding layer between the substrate and an active layer of each of transistors of the pixel driving circuits, and configuring an orthographic projection of light-shielding portions on the substrate to cover an orthographic projection of overlapping portions on the substrate, the light-shielding layer can shield infrared light emitted by the transmitting sensor, thereby preventing the transistors from an interference of the infrared light.
