Abstract
A liquid crystal projector in which light is effectively used and an excellent picture can be obtained is provided. In the liquid crystal projector, dichroic mirrors arranged at different angles are used to separate white light into beams of light of three primary colors of R, G, and B, and the respective beams of the light are incident on microlenses at different angles. The respective beams of light of the three primary colors are distributed by the microlenses to optical components corresponding to pixels, and highly collimated light beams can be obtained by the optical components. Since the highly collimated light beams are made incident on the pixels of the liquid crystal panel, the beams can be certainly made incident on desired pixels.
