Projection type image display system has polarizing element installed on path of light from light source towards polarization beam splitter and path of light reflected by light valve and traveling towards beam splitter

摘要

A polarization beam splitter (250) transmits/reflects incident light beam based on polarization, so that light from illumination system advances towards light valve and light reflected by light valve advances towards projection lens unit. Polarizing elements installed on path of light from light source towards beam splitter and path of light reflected by light valve, for transmitting light beam of preset polarization.
