Abstract

PURPOSE: To disuse a polarizing film or an expensive active LCD and to realize bright and stable driving by using a phase transition type liquid crystal panel as a liquid crystal panel and providing a means for making parallel white light beams incident on the panel. CONSTITUTION: A white light beam from a light source 1 is turned into the parallel white light beams by a condensing lens 2 and reaches a half mirror 3. The 1st light beam reflected by the half mirror 3 reaches the phase transition type liquid crystal panel 6 via mirrors 4 and 5. The 2nd light beam transmitted reaches the phase transition type liquid crystal panel 7 and the 3rd light beam reflected reaches the phase transition type liquid crystal panel 10 via mirrors 8 and 9. After the red transmitted light beam R from the panel 6, the green transmitted light beam G from the panel 7 and the blue transmitted light beam B from the panel 10 pass through a dichroic prism 11, they are synthesized on a screen 13 by a projection lens 12. Thus, the bright and stable driving where the temperature rise of the liquid crystal panel is little is realized without using the polarizing film.
