Abstract

A projector includes: a plurality of image-forming units each including an image forming surface provided with a plurality of micromirrors; a plurality of reflecting units that are provided so as to respectively reflect the plurality of image beams formed by the image-forming units; a beam-combining unit that receives the plurality of image beams via the plurality of reflecting units and emits a combined image beam in which the plurality of image beams are combined such that the propagation directions coincide; and a projection unit that projects the combined image beam emitted from the beam-combining unit. At least two of the image-forming units are arranged such that the image-forming surface of each image-forming means lies in the same plane.
