  • Patent number: 6233030
    Abstract: A liquid crystal display apparatus includes first and second transparent substrates having optical anisotropy, a super twisted nematic liquid crystal body including liquid crystal molecules, an orientation device configured to urge the liquid crystal molecules to orient in a first direction in the inner surface of the first transparent substrate and in a second direction in the inner surface of the second transparent substrate, at least one phase retarder plate and at least one polarizing plate, wherein an angle between an absorption axis of the at least one polarizing plate and a direction of the largest refraction index of the at least one phase retarder plate adjacent to the at least one polarizing plate is 45°±22.5°, an angle between an absorption axis of the at least one polarizing plate and an orientation direction of the liquid crystal molecules in the inner surface of the second substrates adjacent to the polarizing plate is 45°±22.
