Liquid crystal projector equipment in which light from light source 1 is condensed by lens arrays 2 and 4 and lens 5; the condensed light strikes PBS 22 where the s-polarized-light component of the green-color-range light is reflected to strike reflex liquid crystal plate for green color range, and the modulated and reflected p-polarized light component passes through PBS 22 and dichroic prism 11. The p-polarized-light component that has passed through PBS 22 falls on PBS 8 and then on reflex liquid crystal plate 10B for blue color range by way of blue-color-range filter 9B; the modulated reflected p-polarized light passes through PBS 8 to be reflected by dichroic prism 11; the p-polarized-light component that has passed PBS 8 falls on reflex liquid crystal plate 10R for red color range by way of red-color-range light transmitting filter 9R; the modulated and reflected s-polarized light is reflected by dichroic prism 11 and projected on the screen together with image lights of green color range and blue color range by means of the projection lens.
