Abstract
An optical film comprises a light incident side and a light emitting side opposite to the light incident side. A plurality of light incident microstructures are formed on the light incident side, and the light incident microstructures are tapered structures. According to the structural design of the light incident microstructures of the optical film, the light field of a light source can be expanded to achieve the purpose of emitting light at a specific angle. The invention also provides a backlight module and a display device including the optical film.
