Abstract:
A reflection type liquid crystal display comprising:a polarization plate; a quarter wavelength plate comprising a half phase difference film and a quarter phase difference film; an upper substrate; a transparent electrode; a liquid crystal layer; a reflector electrode; and a lower substrate, wherein, said polarization plate, said quarter wavelength plate, said upper substrate, said transparent electrode, said liquid crystal layer, said reflector electrode, and said lower substrate are layered in sequence from a light inputting side, and assuming that an orientation direction of liquid crystal molecules adjacent to said upper substrate is zero degrees, and that a twist direction of the liquid crystal molecules from the upper substrate to the lower substrate is positive, an angle of the polarized light absorption axis of said polarization plate is 5 to 35 degrees with respect to said orientation direction of the liquid crystal molecules, an angle of the optical axis of said half phase difference film is âˆ’15 to 15 degrees with respect to said orientation direction of the liquid crystal molecules, and an angle of the optical axis of said quarter phase difference film is âˆ’75 to âˆ’45 degrees with respect to said orientation direction of the liquid crystal molecules.
