The application provides a display panel, including a plurality of pixel units, a circular polarizer and a plurality of fingerprint identification units disposed on the back of the base substrate. Each fingerprint identification unit disposes a linear polarized liquid crystal layer. A light emitted from each pixel unit is a linear polarized light, which is parallel to an absorption axis of the linear polarized liquid crystal layer. The fingerprint identification unit can realize the fingerprint identification according to the light being emitted from the pixel unit, passing through the circular polarizer to the finger, then being reflected back to the circular polarizer from the finger, and passing through the linear polarized liquid crystal layer.
