Abstract:
A projection-type color liquid crystal display device, comprising:a white light source;a liquid crystal display element which is illuminated by a light flux from said white light source, said liquid crystal display element having pixels grouped into pixel groups, a predetermined number, not less than 2, of the pixels constituting each pixel group;a microlens array provided on a light output side of said liquid crystal display element, said microlens array having microlenses corresponding to the pixel groups, said microlens array dividing the light flux into fluxes which constitute a plurality of images respectively analogous to pixels corresponding to the number of the pixels in said pixel groups;a projection lens for projecting light modulated by said liquid crystal display element;a field lens, provided between said microlens array and said projection lens, for converging the light fluxes which constitute said plurality of images respectively analogous to pixels output by said microlens array at an entrance pupil position of said projection lens; anda coloring means, provided at the entrance pupil position of said projection lens, having regions adjusted to courses of the light fluxes, a number of the regions being in accordance with the number of pixels constituting one pixel group,wherein pixel enlarged images of said plurality of images respectively analogous to pixels are formed at the entrance pupil position of said projection lens without being overlapped.
