ABSTRACT:
The present invention includes a light source which emits a plurality of lights having different wavelength areas, a plurality of image forming devices which are arranged on respective optical paths for the lights emitted by the light source and which are irradiated with the lights to form images via the lights, magnifying devices which process and magnify the respective images formed by the image forming devices to form magnified images, synthesizing devices placed on respective optical paths for the lights via which the magnified images are transmitted, the synthesizing devices superimposing the lights on one another to synthesize the magnified images together to form a synthesized image, and a projection lens placed on an optical path for the light formed by the synthesizing device to project the light.
