<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an uneven pattern formed sheet which exhibits excellent performance when being used as an optical element such as anti-reflective body, retardation plate and light diffusion plate without causing wrinkles in a continuous sheet form. <P>SOLUTION: In the method of manufacturing the uneven pattern formed sheet, a tension is actuated in at least one direction of a stacked sheet in such a state of the stacked sheet that a hard layer is stacked on one surface or both surfaces of a heat-shrinking film to cause heat shrinking and, thereby, at least the hard layer on the stacked sheet is meander-deformed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
