Optical film and method for manufacturing optical film

Abstract

Visibility of an optical film at the time of handling can be improved, and an antireflection region and a visible region can be easily formed on a surface of the optical film in an identical processing step. An optical film 1 includes a base material 11 having flexibility and a resin layer 12 laminated on at least one of surfaces of the base material 11. The resin layer 12 includes a concave-convex pattern region 2 in which a micro concave-convex structure 20 composed of a plurality of convexities 21 or concavities 22 arrayed at a pitch P less than or equal to a wavelength of visible light are formed and a strip-shaped line marker region 3 in which a plurality of ridge portions 31 arrayed at intervals from one another at a track pitch Pt more than or equal to the wavelength of visible light are formed.
