PROJECTOR

PROBLEM TO BE SOLVED: To provide a projector reducing a shadow of a black matrix. SOLUTION: The projector 1 has a lighting unit (light source lamp 111) which emits illumination light, an electrooptical modulating unit (liquid crystal panel 141) having nearly rectangular pixels formed in a lattice sh...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a projector reducing a shadow of a black matrix. SOLUTION: The projector 1 has a lighting unit (light source lamp 111) which emits illumination light, an electrooptical modulating unit (liquid crystal panel 141) having nearly rectangular pixels formed in a lattice shape and modulating the illumination light for each pixel according to image information to emit it as modulated light, an optical path deflecting unit 160 which deflects the optical path of the modulated light emitted by the pixels of the electrooptical modulating unit to a reference direction and also deflects the optical path to a corner direction of the pixels while moving it by a predetermined distance, and a projection optical unit (projection lens 170) which projects the modulated light deflected by the optical path deflecting unit 160.
