LIQUID CRYSTAL DISPLAY DEVICE AND PROJECTOR USING THE SAME

摘要

A reflecting type liquid crystal display device having a perpendicularly aligned structure and shorter response time and a projector using the same are provided. The reflecting type liquid crystal display device includes a first substrate having a reflective electrode, a second substrate having a transparent electrode, first and second alignment layers provided on the first substrate and the second substrate to be opposed to and face each other, a spacer interposed between the first alignment layer and the second alignment layer to form a predetermined cell gap therebetween, and vertically aligned liquid crystals injected into the cell gap, the cell gap being not greater than 1.0 mu m, the dielectric anisotropy of the liquid crystals being negative value, and the refractive index anisotropy of the liquid crystals being not less than 0.14. The projector includes a light source; a color separation unit, a reflecting type liquid crystal display device for selectively reflecting light beams of the respective colors separated by the color separation unit and sequentially incident thereto to form an image, an optical path changing unit disposed on an optical path between the light source and the reflecting type liquid crystal display device, for changing the optical path of the light incident from the light source to be directed toward a screen via the reflecting type liquid crystal display device, and a projection lens unit.
