Method of manufacturing an optical substrate using a film-like mold, the manufacturing apparatus and resulting optical substrate

摘要

The method for manufacturing an optical substrate, a step S0 providing a long film-shaped mold having a patterned surface, the step S2 of forming a coating of the sol-gel material to the concavo-convex pattern surface of the film-like mold, the sol-gel material the concave-convex pattern surface and the substrate of the film-like mold coating is formed by opposed, it was pressed against the press roll on the opposite side to the concave-convex pattern surface of the film-like mold formed on the concavo-convex pattern surface wherein a coating film and process S3 to close contact with the substrate, a step S4 for peeling the film-shaped molded from the coating film, and a step S5 for curing the coating film adhered to the substrate. Used in diffraction and scattering of light, it can be manufactured at a high throughput optical substrate having heat resistance and weather resistance.
