Abstract:
1. A liquid crystal display device comprising: first and second electrode substrates; a liquid crystal layer which is held between the first and second electrode 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 first and second electrode substrates on the sides opposite to the liquid crystal layer; first and second half-wavelength plates respectively disposed on the first and second optical anisotropic elements; and first and second polarizing plates respectively disposed on the first and second half-wavelength plates; wherein the first electrode substrate includes a light transmitting section which permits backlight light incident from the first polarizing plate side to transmit therethrough and a light reflecting section which reflects ambient light incident from the second polarizing plate side, and at least one of the first and second optical anisotropic elements is formed of two retardation plates having a retardation in a plane; wherein at least one of the two retardation plates is a liquid crystal film; and wherein the liquid crystal film is one of a nematic liquid crystal and smectic liquid crystal which are aligned and solidified.
