Abstract

PURPOSE: To realize a large-sized projection color display device without separating light from 8 projection light source into spectral components by using a phase transition type liquid crystal panel capable of large-capacity display. CONSTITUTION: In this device, three phase transition type liquid crystal panels 9a to 9c provided with red, green, and blue color filters are arranged, and light from a light source 1 is made incident on a dichroic prism 4 through these panels and is projected on a screen 5. That is, light passing panels 9a to 9c which allow red, green, and blue light to selectively pass through is synthesized on the screen 5 through the prism 4 where red and blue dichroic prisms are stuck to each other, thereby realizing the large-sized projection color liquid crystal display without separating light from the projection light source l into spectral components.
