Patent ID: 7901081

Claim:
A method of manufacturing an optical compensation element, comprising: (a) temporarily attaching an inorganic substrate made of a birefringent inorganic material to a base member with a temporary bond; (b) grinding/polishing a surface of the inorganic substrate mounting the base member, to which the inorganic substrate is temporarily attached, on a grinding/polishing device; (c) attaching a light transmissive support substrate to the surface of the inorganic substrate thus ground/polished in step (b) on the opposite side to the side of the base member; and (d) separating the inorganic substrate temporarily attached to the base member from the base member such that the light transmissive support substrate remains attached to the surface of the inorganic substrate following separation of the inorganic substrate from the base member, wherein the steps (a), (b), (c), and (d) are executed in this order.
