Abstract
Optical system of a liquid crystal projector with three reflective liquid crystal displays, wherein a first light path changing part among first to third light path changing parts is designed such that a first color path surrounds three faces of a first of liquid crystal panel except a side of a connector thereof, for avoiding interference of the color light path with the connector, thereby reducing a total length of the optical system.
