PURPOSE:To obtain high luminance and high resolution by synthesizing a transmission light from each liquid crystal panel by a prism means, and observing an enlarged image of a color image by a lens means. CONSTITUTION:An R transmission light from a liquid crystal panel 1 is reflected by a joint surface 8a of a first prism 8 or a joint surface 11b of a fourth prism 11 and emitted from the prism 11, a B transmission light from a liquid crystal panel 2 is reflected by a joint surface 9a of a second prism 9 or a joint surface 11a of the prism 11 and emitted from the prism 11, and a G transmission light from a liquid crystal panel 3 travels straight as it is in a third and a fourth prisms 10, 11 and is emitted from the prism 11. In that case, the panels 1, 2 and 3 are positioned exactly and attached to each incident surface so that optical axes in emitting ends of each R, G and B transmission light coincide with each other, therefore, each transmission comes to be synthesized, and accordingly, a color image 14 by the panels 1, 2 and 3 appears on the emitting surface of the prism 11. Subsequently, this color image is made incident on a convex lens 12, by which a color enlarged image 15 is observed. |
