PROBLEM TO BE SOLVED: To provide a color exposure device using a liquid crystal shutter capable of forming an excellent color image in spite of the chromatic aberration of a condensing optical system. SOLUTION: This color exposure device is provided with color light sources (101r, 101g and 101b) for generating a plurality of color light beams, an optical shutter means (120) for controlling the transmission of the plurality of color light beams and a transmission type lens means (130) for making transmitted light from the optical shutter means form an image. The optical shutter means has a plurality of shutter apertures in order to respectively and independently control the transmission of the plurality of color light beams, and the diameters of the openings of the plurality of shutter apertures are made different in accordance with the corresponding color light beams. |
