The invention provides a display panel and a display device, being characterized in that a fingerprint identification area of the display panel comprises a substrate layer and a pixel circuit; the pixel circuit comprises a DTFT unit, a source electrode wire, a drain electrode wire and a capacitor unit which are arranged on the substrate layer; a source region of the DTFT unit is connected with thesource electrode wire; a drain region of the DTFT unit is connected with the drain electrode wire, and a light transmitting region is arranged between a channel region of the DTFT unit and the drainelectrode wire; the projection of the channel region of the DTFT unit on the substrate layer and the projection of the channel region close to the source electrode wire on the substrate layer reduce the width of a gap between the channel region of the DTFT unit and the source electrode wire and increase the distance between the channel region of the DTFT unit and the drain electrode wire, so thatthe light transmission area of a single light transmission region is increased; and the projection of the capacitor unit on the substrate layer covers the projection of the channel region on the substrate layer, so that diffraction of a gap between the channel region and the source electrode wire is reduced, and the under-screen fingerprint imaging quality is improved.
