Fingerprint recognition sensor, manufacturing method thereof and display device

Abstract

A fingerprint recognition sensor includes a plurality of fingerprint recognition units arranged in an array. Each of the fingerprint recognition units includes a base substrate, an image capturing device disposed on one side of the substrate, and a first grating structure and a second grating structure sequentially disposed on the other side of the base substrate, the first grating structure has a first imaging hole at a position opposite to the image capturing device and the second grating structure has a second imaging hole at a position opposite to the image capturing device, and an extending direction of a slit of the first grating structure is perpendicular to an extending direction of a slit of the second grating structure.
