Abstract: PROBLEM TO BE SOLVED: To obtain high-grade videos which have decreased unequal luminosity and colors, is light and has a good contrast by specifying the position of a lens plate which is arranged in the position near a condenser lens among the lens plates consisting of plural unit lenses. SOLUTION: The second lens plate 301 is arranged in the position where nearly the same optical distance as the optical distance of an aperture-stop 105 viewed from the liquid crystal panel on nearly the same plane as the plane of this aperture-stop 105 is attained. The size of the lens aperture of this second lens plate 301 is set smaller than the size of the aperture-stop 105 of the projecting lens. The second lens plate 301 is arranged in the position where nearly the same optical distance as the optical distance of the aperture-stop 105 is attained and, further, the size of the lens aperture is set larger than the effective diaphragm surface of the projecting lens and, therefore, the condensing position of the light made incident on the liquid crystal panel via the second lens plate 301 and reflected is within the effective diaphragm surface 601 of the projecting lens.  The efficient incidence of this light on the projecting lens is made possible. The light reflected by the liquid crystal panel is thus efficiently utilized for projection without increasing the size of the projecting lens.
