Abstract
An optical film includes a base member having convex structures that are two-dimensionally and orderly arranged on a surface thereof and a hard-coating layer provided on the surface of the base member, the surface having the arranged structures thereon. A continuous wave surface is provided on a surface of the hard-coating layer so as to approximately conform to the shape of the structures of the surface of the base member, a maximum amplitude A and a minimum wavelength λ of the continuous wave surface are each substantially uniform, and a ratio (A/λ) of the maximum amplitude A to the minimum wavelength λ is more than 0.002 and 0.011 or less.
