Abstract
This disclosure relates to an optical fingerprint identification display screen and a display device. In this disclosure, a plurality of photosensitive elements for fingerprint identification is arranged on an array substrate, such that mesh regions of a mesh-like black matrix layer corresponds to the photosensitive elements. A plurality of light guide members at least covering each of the photosensitive elements is arranged between each photosensitive element and the counter substrate. Since the light guide members and the counter substrate are in contact with each other, light reflected from ridges and valleys of a fingerprint will enter the light guide members maximally after passing through the mesh regions of the black matrix layer, and then directly impinge on the photosensitive elements after refraction within the light guide members.
