An optical film includes a first refraction layer having a first surface with first optical lens patterns for scattering light and a second surface opposite to the first surface, the first optical lens patterns having a lens shape, and a second refraction layer on the first surface and having second optical patterns for redirecting light in a first direction that is perpendicular to the second surface of the first refraction layer, the second optical patterns being linearly arranged.
