Abstract:
An optical system of a liquid crystal projector for superimposing, enlarging, and projecting pictures displayed on first to third liquid crystal panels by using color lights received through first to third light path changing parts, the first light path changing part comprising:a first sub-light path part for making a first time alteration of a linearly polarized light component of the color light received from one of the first to third light path changing parts; a second sub-light path part for reflecting the color light from the first sub-light path part, and making a second alteration of the linearly polarized component of a reflected color light, and forwarding to the first sub-light path part; and, a third sub-light path part for directing the color light received through the second sub-light path part and the first sub-light path part to the first liquid crystal panel relevant to the color light, wherein the first to third sub-light path parts are arranged spaced away from the first liquid crystal panel, on sides of the first liquid crystal panel respectively except a side the connector is fitted thereto.
