<p>A polymer dispersion type liquid crystal display element is characterized by overlaying two layers of polymer dispersion type liquid crystal layers (8,9) having liquid crystal drops (12,13) positive in dielectric anisotropy dispersed in a polymer in which light scattering and transmission are controlled electrically, and interposing a transparent support element (2) for scattering light between the polymer dispersion type liquid crystal layers (8,9), and a liquid crystal display device comprises a colored reflector plate (15) disposed on the back of one polymer dispersion type liquid crystal layer. In one of the two layers of polymer dispersion type liquid crystal layers (8,9), a liquid crystal layer containing a dichroic dye is dispersed, and coloring and light transmission are electrically controlled, and a white reflector plate (15) is disposed on the back side of one of the polymer dispersion type liquid crystal layers to realize a liquid crystal display device. By composing the liquid crystal display element and liquid crystal display device in such constitutions, both light scattering capacity and contrast may be enhanced at the same time. <IMAGE></p> |
