Light direction control film, method for manufacturing the same and fingerprint recognition panel

A light direction control film, having, in a direction perpendicular to a thickness direction of the light direction control film, a refractive index decreasing from a central region of the light direction control film to each of both sides of the light direction control film gradually, wherein light direction control film comprising a fingerprint recognition panel, further comprising:

• a substrate;
• a light sensor provided on the substrate;
• and the light direction control film;
• wherein the light sensor is provided between the light direction control film and the substrate, and an orthographic projection of the light sensor on the substrate is located within an orthographic projection of the light direction control film on the substrate, wherein the orthographic projection of the light sensor on the substrate completely coincides with the orthographic projection of the light direction control film on the substrate.
