摘要：
A liquid crystal projector includes an illumination optical system provided with a light source, first and second lens arrays arranged in this order from the light source, a liquid crystal panel, and a polarization changing optical system arranged between the first and second lens arrays. This makes it possible to install the polarization changing optical system and the optical integrator in a smaller space.
