Disclosed are: an optical film which has a moth eye structure, while having directivity in optical characteristics such as reflection and scattering; a method for producing the optical film; and a method for controlling the optical characteristics of the optical film. Specifically disclosed is an optical film having a moth eye structure that comprises a plurality of projections, wherein the plurality of projections include a plurality of slanted projections that are inclined to a film surface and the plurality of slanted projections are inclined in a generally same direction when the film surface is viewed in plan. Also specifically disclosed is a method for producing an optical film having a moth eye structure that comprises a plurality of projections, which comprises a step wherein a physical force is applied to the moth eye structure. Further specifically disclosed is a method for controlling the optical characteristics of an optical film having a moth eye structure that comprises a plurality of projections, wherein a physical force is applied to the moth eye structure. |
