Projector device capable of obtaining a high luminance without increasing output of light source

摘要

In a projector device for magnifically projecting onto a screen a beam of light emitted from a light source which is irradiated at a mirror reflecting type light modulator after being color-separated into light beams of three primary colors and after respective light beams of primary colors modulated in the mirror reflecting type light modulator are synthesized by a color prism, a light beam emitted from a first light source is polarized into an “p” polarization by a polarization converter and a light beam emitted from a second light source is polarized into a “s” polarization by the polarization converter, thereby both light beams are synthesized by a polarization beam splitter.
