Abstract

A display panel and a display device, a fingerprint identification region of the display panel includes a substrate layer and a pixel circuit; the pixel circuit includes a DTFT unit, a source wiring, a drain wiring, and a capacitor unit arranged on the substrate layer; a source region of the DTFT unit is connected with the source wiring, a drain region of the DTFT unit is connected with the drain wiring, a light-transmitting region is located between a channel region of the DTFT unit and the drain wiring; a projection of the capacitor unit on the substrate layer covers the projection of the channel region on the substrate layer, thereby reducing the diffraction generated by the light-transmitting gap between the channel region and the source wiring, and improving the imaging quality of fingerprint under the screen.
