Original Abstract Submitted

the disclosure provides a fingerprint recognition module and a display apparatus, including: a base substrate; a photosensitive device layer above the base substrate and including a plurality of photosensitive devices; a bias metal layer and a noise reduction metal layer sequentially on the side of the photosensitive device layer distant from the base substrate; a light guide film layer including at least two light shielding layers arranged in a stacked manner, and a microlens layer on the side of the light guiding film layer facing away from the photosensitive device layer and including a plurality of microlenses. each of the light shielding layers is provided with light transmitting holes arranged in an array, the light transmitting holes in all the light shielding layers are provided in a one-to-one correspondence manner. an orthogonal projection of the microlens covers the orthogonal projections of the light transmitting holes on the base substrate.
