ABSTRACT:
A liquid crystal material is sealed between substrates. The liquid crystal material exhibits an antiferroelectric phase while the liquid crystal is in a bulk state. In the liquid crystal layer sealed between the substrates, due to aligning forces of alignment films, liquid crystal molecules are aligned in a state wherein there is no correlation in molecular order between adjoining smectic layers, and the director of the liquid crystal layer is substantially coincident with the direction of a normal line of the smectic layers. The director varies continuously in accordance with the polarity and magnitude of a voltage applied between electrodes formed on the substrates. Arranging polarization plates so that the substrates are sandwiched therebetween enables a gradation to be displayed.
