Abstract: An optical film is provided. The optical film includes a base film and a cover film. The base film includes a base member and a plurality of lens patterns disposed on the base member. The plurality of lens patterns protrudes from the base member and extends in a first direction. The cover film is disposed on the base film to cover the base member and the plurality of lens patterns. A refractive index of at least one of the lens patterns is smaller than a refractive index of the cover film. An aspect ratio of the at least one of the lens patterns ranges from 0.8 to 1.6.
