ABSTRACT:
A projector module adopts a structure having an optical image forming block and an optical block integrated via a locking member. The optical image forming block adopts a structure achieved by disposing an aluminum substrate at which an LED is mounted and a liquid crystal panel in a casing constituted with a plastic material having low thermal conductivity. The locking member is formed by bending a metal sheet through a sheet metal bending process and the locking member is set in surface contact with the substrate. The optical block adopts a structure achieved by disposing a PBS and a reflecting member at the casing constituted with a plastic material having low thermal conductivity with a quarter-wave plate disposed at the boundary of the two members.
