Abstract:
A reflective type liquid crystal display device, having a liquid crystal display element provided with:a quarter-wavelength plate; anda pair of substrates, each substrate being provided with a transparent electrode,the reflective type liquid crystal display device carrying out display by using ambient light,said element, comprising:a reflector member, possessing an excellent polarization preservation property, for reflecting incident light; anda complex member, composed of a complex of liquid crystal and a polymer that are phase separated, for selectively diffusing incident light,wherein the liquid crystal display element further includes a liquid crystal layer disposed between the substrates and composed of liquid crystal and dichroic dye having a transitional dipole moment at least in a direction of a longer axis of the molecule, andthe complex member is an anisotropic diffusing film for diffusing only light polarized in a particular direction while preserving the direction of polarization of the light,wherein the reflector member is disposed on one of the substrates, the quarter-wavelength plate is disposed on the reflector member, and the anisotropic diffusing film is disposed on the quarter-wavelength plate.
