Abstract
An image synthesizing optical apparatus includes displays for modulating first, second, and third color beams according to image signals and outputting the first, second, and third color beams thus modulated. The optical axis of the second color beam coincides with the optical axis of the first color beam. The optical axis of the third color beam crosses a midpoint between the first and second displays on the optical axes of the first and second color beams. The apparatus has a color beam combining unit at the midpoint and combining the color beams from the respective displays, and a support supporting the foregoing components. The support maintains optical path lengths of the respective color beams from the displays to the color beam combining unit equal even with a change in temperature.
