Abstract
A method for producing an optical substrate includes: a step of preparing a long film-shaped mold having a concave-convex pattern surface having a concave-convex pattern; a step of forming a coating film made of a sol-gel material on the concave-convex pattern surface of the film-shaped mold; a step of adhering the coating film, which is formed on the concave-convex pattern surface of the film-shaped mold, to a substrate by arranging the concave-convex pattern surface of the film-shaped mold on which the coating film made of the sol-gel material is formed to face the substrate and by pressing a pressing roll against a surface of the film-shaped mold on a side opposite to the concave-convex pattern surface; a step of releasing the film-shaped mold from the coating film; and a step of curing the coating film adhered to the substrate.
