A new multicolor liquid-crystal display device is described. The device is of a field-in-duced tunable birefringence type and employs a unique hybrid-aligned nematic (HAN) electro-optical cell between polarizers. The cell consists of two electrode substrates sandwiching a nematic fluid with either a positive or negative dielectric anisotropy, the two substrates hav-ing homeotropic and homogeneous boundary surfaces, respectively; thereby the nematic direc-tor is varied continuously, lying perpendicular to one substrate and parallel to the other. The multicolor display based on the HAN has such practically favorable features as remarkably lower driving-voltage, easier tolerance for fluctuation of operational conditions, and higher brightness of colors compared to previously described color liquid-crystal displays.
