Abstract
An optical film includes a light-transmissive substrate and a first annular lens group. The light-transmissive substrate has a first surface and a second surface opposite to each other. The first annular lens group is disposed on the second surface, and the first annular lens group is configured to allow light to pass through. The reflectivity of the first annular lens group decreases along a direction away from a central axis of the first annular lens group, and an extending direction of the central axis is the same as a thickness direction of the light-transmissive substrate.
