OPTICAL FILM, OPTICAL FILM MANUFACTURING METHOD AND SURFACE LIGHT-EMITTING BODY

摘要

This optical film includes a diffraction grating layer made of a transparent material, and a concavoconvex surface structure layer made of a transparent material. The surface light-emitting body includes the aforementioned optical film. This optical film manufacturing method involves supplying a second active energy ray curable composition between a substrate and a mold having a diffractive grating transfer part, irradiating second active energy rays to obtain a laminate having a diffractive grating layer on convex structure transfer part, and irradiating first active energy rays.
