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 a light transmission part disposed between the color filters with different colors;
the first light shield layer comprises a first opening and a light shield part, wherein the light transmission part and the first opening 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
wherein the color film layer further comprises a first black matrix disposed between the color filters with different colors, the first black matrix is provided with a second opening which forms the light transmission part, there is an overlapping area between an orthographic projection of the second opening on a base substrate and an orthographic projection of the fingerprint identification sensor on the base substrate, and the second opening pin-hole images a fingerprint in contact with the display panel onto the fingerprint identification sensor.
