Document Type and Number:
WIPO Patent Application WO/2010/095402
Kind Code:
A1
Abstract:
A method for manufacturing an optical member having a surface shape includes: a step of sandwiching a substrate with a pair of flexible sheets having a surface shape forming die at least on one of the sandwiching surfaces; a step of bringing the space between the pair of flexible sheets into the vacuum state, applying heat and pressure to the sandwiching surfaces of the flexible sheets, and forming a surface shape pattern at least on one of the surfaces of the substrate; and a step of cooling the sandwiching surfaces of the pair of flexible sheets and solidifying the substrate having the surface shape pattern formed thereon.
