Abstract
An optical structure film and a light source module are provided. The optical structure film includes multiple optical unit microstructures. Each of the optical unit microstructures has four side surfaces and an inwardly concave beam splitting surface. The beam splitting surface is respectively connected to the side surfaces, and the beam splitting surface has four endpoints when viewed from a front viewing angle. Connection lines of the four endpoints form a rectangle. The beam splitting surface includes at least one beam splitting curved surface. A junction of the at least one beam splitting curved surface and one of the four side surfaces is a first line segment. A projection of a midpoint of an edge of the rectangle on the beam splitting surface overlaps with a relative extreme point of the first line segment.
