A liquid crystal projector splits light from a light source into three lights of three different primary colors, respectively, through an optical system, enters the three lights into three liquid crystal display panels corresponding to the three different primary colors, respectively, combines the three lights reflected from the three liquid crystal display panels using a prism, and projects the combined three lights through a first lens onto a screen. The liquid crystal projector is provided with two second lenses each of which is disposed at a respective one of two entrance sides of the prism on which the three reflected lights are incident, and a combination of the two second lenses, the prism and the first lens constitute a projection lens optical system which projects the combined three lights onto the screen.
