Abstract:
A reflective type liquid crystal display device, having a liquid crystal display element provided with:a quarter-wavelength plate; and a 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; and a complex member, composed of a complex of liquid crystal and a polymer that are phase separated, for selectively diffusing incident light while transmitting the incident light, wherein the complex member is a liquid crystal layer disposed between the substrate and the reflector member, the liquid crystal being oriented with a twist angle in the range of 40Â° to 50Â°, and the quarter-wavelength plate is disposed between the reflector member and the liquid crystal layer, and a polarizer plate is provided on a side where the incident light enters.
