The invention enables a sufficiently bright color image to be displayed without increasing a heating value with a simple and compact structure which is easily assembled and adjusted. A first microlens for condensing light and a second microlens for changing the travel direction of light are provided, every three pixel electrode parts in a liquid crystal panel. The travel directions of B and G rays condensed by the first microlens are changed by the second microlens, thereby allowing the principal rays to perpendicularly enter the pixel electrode part. The color ray passing through the second microlens focuses on the corresponding pixel electrode part. The first and second microlenses construct a relay optical system having the magnification of 1. Light reflected by the pixel electrode part is transformed by the same first microlens into a parallel ray bundle, and the ray bundle goes out from the liquid crystal panel. The outgoing light of each color ray from the liquid crystal panel is directed toward the incident direction.
