Abstract
A reflective-type liquid crystal display is configured so that a liquid crystal is sandwiched between a Thin Film Transistor (TFT) substrate and a facing substrate. A polarizer is formed on a side opposite to a side being in contact with the liquid crystal on a second transparent insulating substrate with a layer-stacke ¼ wavelength plate constructed by combining a ½ wavelength phase difference film with a ¼ wavelength phase difference film. Both films are made from a norbornene polymer and are sandwiched between the polarizer and second transparent insulating substrate. A permittivity anisotropy of the liquid crystal is set to be about 6 or more.
