ABSTRACT:
The invention provides a reflective liquid crystal display device being low cost, high reflectance, and high contrast in the reflective liquid crystal display device of VA system providing a diffusion reflective plate having uneven shape and using negative dielectric anisotropy liquid crystal and a substrate using for a reflective liquid crystal display device. Assuming that reflective surface of the reflective plate has plurality of small mirror surfaces, direction of normal vector In of the small mirror is constructed so that standard deviation of probability distribution existing within angle range of azimuth angle from φn to φn+1° is 0.1 or more.
