Abstract
A display panel and a display device are provided, which the display panel including a display substrate, a counter substrate, and a backlight. The display substrate includes a first thin film transistor layer, a touch electrode, and a pixel definition layer. The substrate includes a second thin film transistor layer and a photosensitive component. The second thin film transistor layer has a plurality of thin film transistors. The photosensitive component is connected to an underside of the second thin film transistor layer. The photosensitive component receives a reflected light of a user's fingerprint to identify an identification of the user.
