Abstract

Provided are a micro mirror device capable of realizing color images without a color wheel by selectively reflecting color beams using a plurality of micro mirrors whose driving axes are positioned in different directions, and a projector employing the same. The micro mirror device can individually control a plurality of micro mirrors, the micro mirror device comprising a plurality of micro mirror units having micro mirrors whose driving axes are positioned at predetermined different angles, the micro mirror units for reflecting light incident in different directions. Also, the projector includes a light source for illuminating light; a light separation unit for separating light generated by the light source into several beams according to wavelength regions, and for reflecting or projecting the beams at different angles; a micro mirror device including a plurality of micro mirror units which are composed of a plurality of micro mirrors whose driving axes are respectively positioned at different predetermined angles, the micro mirror device for realizing an image by selectively reflecting the beams, which are passing through the light separation unit, in a predetermined direction and at a predetermined angle; and a projection lens unit for magnifying and projecting light generated by the micro mirror device toward a screen.
