METHOD FOR PRODUCING MICROLENS SUBSTRATE, MICROLENS SUBSTRATE, TRANSLUCENT SCREEN AND REAR PROJECTOR

摘要

PROBLEM TO BE SOLVED: To provide a microlens substrate excellent in utilization efficiency of light and viewing angle characteristic and giving an image excellent in contrast, a method for producing a microlens substrate by which such a microlens substrate can be efficiently produced, and a translucent screen, and a rear projector equipped with such a microlens substrate. SOLUTION: The method for producing a microlens substrate comprises steps of: forming a photosensitive resin layer on a light emitting surface of a substrate body; exposing parts of the photosensitive resin layer corresponding to light condensing parts of microlenses to form cured parts; removing an uncured part of the photosensitive resin of the photosensitive resin layer; forming a metallic material layer on the light emitting surface of the substrate body by vapor phase film deposition; and removing the metallic material provided on the cured parts together with the cured parts so as to form openings.
