METHOD AND APPARATUS FOR PRODUCING OPTICAL ELEMENT, AND PROJECTOR

摘要

PROBLEM TO BE SOLVED: To highly accurately produce an optical element wherein a plurality of trigonal prisms having fine triangular cross sections are formed into parallel crosses. SOLUTION: Water repelling release films 33, 34 are formed on the respective opposed surfaces of a mold 31 and a substrate 32 and the tip of a potting nozzle 35 is inserted in the mold 31 from the close contact surface of the mold 31 and the substrate 32 on the side of the substrate 32 not only to inject a photosetting resin 36 in the mold but also to vent the air present between the mold 31 and the substrate 32 from air vent holes 38-41 and a μ-kaleido element used in a liquid crystal display is produced by a 2P method.
