Abstract:
Disclosed is a viewing angle control film including a transparent substrate and a plurality of first optical microstructures. The first optical microstructures are disposed on a surface of the transparent substrate, and a disposed range thereof has a geometric center. Each of the first optical microstructures has a first refracting surface away from the geometric center. First refracting angles included between the respective first refracting surfaces of the first optical microstructures and the surface of the transparent substrate are asymmetrically distributed with respect to the geometric center. A display apparatus adopting the viewing angle control film is also provided.
