摘要： A polymer dispersion type liquid crystal display element includes two layers of polymer dispersion type liquid crystal layers being overlaid and having liquid crystal drops positive in dielectric anisotropy dispersed in a polymer in which light scattering and transmission are controlled electrically, a transparent support element for scattering light between the polymer dispersion type liquid crystal layers, being interposed and a liquid crystal display device having a colored reflector plate 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, a liquid crystal layer containing a dichroic dye is dispersed, and coloring and light transmission are electrically controlled, and a white reflector plate is disposed on the back side of one of the polymer dispersion type liquid crystal layers to realize the 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.
