1. A display panel, comprising a fingerprint identification sensor, a first light shield layer disposed above the fingerprint identification sensor, and a color film layer disposed above the first light shield layer,
wherein the color film layer comprises color filters with different colors and light transmission parts disposed between the color filters with different colors;
the first light shield layer comprises first openings and a light shield part, there is an overlapping area between an orthographic projection of the light transmission parts on the display panel and an orthographic projection of the first openings on the display panel, wherein the light transmission parts and the first openings form fingerprint imaging holes, and the fingerprint imaging holes are configured to allow fingerprint reflected light to transmit and reach the fingerprint identification sensor, and the light shield part is configured to block out stray light; and
the display panel further comprises a touch structure layer, wherein the touch structure layer comprises a plurality of touch electrodes, and there is no overlapping area between an orthographic projection of the touch electrodes on the display panel and an orthographic projection of the fingerprint imaging holes on the display panel.
