ABSTRACT:
A liquid crystal display device includes first and second electrode substrates, a liquid crystal layer which is held between the substrates and in which nematic liquid crystal molecules are arranged in substantially parallel to each of the substrates without distortion, first and second optical anisotropic elements respectively disposed on the substrates on the sides opposite to the liquid crystal layer, first and second half-wavelength plates respectively disposed on the optical anisotropic elements, and first and second polarizing plates respectively disposed on the half-wavelength plates. Particularly, the substrate includes a light transmitting section which permits backlight light from the polarizing plate side to transmit therethrough and a light reflecting section which reflects ambient light from the polarizing plate side and at least one of the optical anisotropic elements is formed of two retardation plates having a retardation in a plane.
