PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical plate-like member having small optical distortion, excellent transferability of a rugged pattern, heat resistance, moisture resistance and productivity. SOLUTION: The method for manufacturing the optical plate-like member comprises a step of molding a photo-crosslinking resin mixture containing a photo-crosslinking resin, a photo-crosslinking agent and a photo-crosslinking initiator in a plate-like material 4 by extrusion molding, a step of forming the rugged pattern on the surface of the material 4 by setting a temperature of the material 4 within a range of a glass transition temperature of the resin±20 deg.C and a viscosity of the material to 102 to 105 Pa.s, and thereafter a step of crosslinking the photo-crosslinking resin and the photo-crosslinking agent by emitting an ultraviolet ray thereto. |
