Abstract
Light from a light source is divided into P-and S-polarized beams by means of a polarizing beam splitter and converted into the same polarized wave. Two polarized waves are incident on a liquid crystal panel symmetrically at the same angle on right and left sides. An integrator comprising two lens arrays is disposed before and behind these polarization converting elements, and therefore brightness can be uniformly increased with a simple construction while achieving space saving.
