METHOD FOR MANUFACTURING OPTICAL SHEET AND DEVICE FOR MANUFACTURING OPTICAL SHEET

摘要

A method for manufacturing an optical sheet (90), wherein in a functional structure formation step (S3), a functional structure (82) having a reflection function or a diffusion function is formed on at least one surface of a resin sheet (70), and a cutout reference mark (85) is put at a reference position for obtaining the intended optical sheet by cutting the resin sheet (70), and on the basis of the cutout reference mark (85), the resin sheet on which the functional structure is formed is precisely cut by a cutting device (40) to obtain the optical sheet of an intended size.
