PROBLEM TO BE SOLVED: To provide a repairable fixing structure of a light valve means and to prevent the positional shift after fixation of a liquid crystal projector. SOLUTION: A metal brazing segment 207 is provided on a portion of a supporting part of a light valve panel 2 to fix the same by soldering a holder for holding a prism part. The movement of the light valve 2 after the fixation with respect to a base 201 may be prevented and the positional shift of the image to be projected may be prevented by forming the structure in the manner described above. The removal of the light valve panel 2 is made possible and maintenability is improved by removing the soldering. Further, the ratio of the coefficients of linear expansion of the material constituting the light valve panel and the base segment supporting the same is specified between 1 to 3 and the positional shift of the image to be projected is prevented by temperature cycles.
