Patent ID: 8107021

Claim:
A liquid crystal projection apparatus for projecting colored imaging light obtained by image synthesizing means that is adapted to illuminate three liquid crystal panels with lights of three primary colors to generate imaging lights of three primary colors and synthesize the imaging lights into the colored imaging light, the image synthesizing means comprising: a color synthesization prism having an upper surface, a lower surface facing the upper surface, and three incident faces between the upper and lower surfaces; an upper prism pedestal provided on the upper surface of the color synthesization prism; a lower prism pedestal provided on the lower surface of the color synthesization prism; an upper liquid crystal panel holder provided on top of the upper prism pedestal and having a multiplicity of first jointing sections, a lower liquid crystal panel holder provided on the bottom of the lower prism pedestal and having a multiplicity of second jointing sections; three liquid crystal panels; and three liquid crystal panel mounting members securely fixing thereon the three liquid crystal panels, the three liquid crystal panel mounting members arranged on the respective three incident faces of the color synthesization prism and adapted to joint the first jointing sections located in association with the respective incident faces to corresponding second jointing sections located in association with the corresponding incident faces.
