Abstract: PROBLEM TO BE SOLVED: To provide a color projector which improves image quality and can make the design of a projection lens unit compact by varying the sizes of the effective surfaces for forming images of plural selected display elements in such a manner that generated chromatic aberrations can be corrected. SOLUTION: The first to third display elements 131, 133 and 135 form the images with respect to light of R, G and B colors, respectively, and therefore, these light beams are synthesized by a synthesizing means 140 and the chromatic aberrations are generated when the light beams pass the projection lens unit 150 in the same optical path. The >=2 display elements selected from the first to third display elements 131, 133 and 135 are consequently varied in the sizes of the effective surfaces for forming the images. As a result, the sizes of the screens to the respective colors which are converged and diffused by the projection lens unit 150 and are converged into the screen 160 may be made the same.  Then, the occurrence of magnification differences to the red, green and blue is substantially prevented and the degradation in the image quality by the chromatic aberrations may be prevented.
