Abstract

A display panel and a display device thereof are provided. The display panel comprises a display module comprising a first substrate and a first polarizer, wherein a light-exiting surface of the display module is arranged on an outer side of the first polarizer; a fingerprint recognition module disposed on an outer side of the first substrate and comprising a fingerprint recognition layer and a second polarizer disposed on an inner side of the fingerprint recognition layer; and a light source disposed on an inner side of the first polarizer. The fingerprint recognition layer recognizes fingerprint based on fingerprint signal light. The first polarizer is engaged with the second polarizer, such that the fingerprint signal light is transmitted through the first polarizer and the second polarizer without a light intensity loss, and the second polarizer reduces the light intensity of fingerprint noise light.
