ABSTRACT:
An antiferroelectric liquid crystal display device includes: an active matrix type LC cell and an antiferroelectric liquid crystal sealed in the cell. Liquid crystal molecules aligned to one of a first aligning direction and a second aligning direction are aligned in the other aligning direction in accordance with an applied voltage, thus forming a plurality of regions of different alignment states in a range shorter than a wavelength of light in a visible light band, and directions of said directors are changed in accordance with a ratio of regions in a first alignment state to regions in a second alignment state. The liquid crystal molecules may behave along a predetermined cone by a phase transition precursor in accordance with an applied voltage. The liquid crystal molecules may behave so as to be inclined in a direction perpendicular to an electric field, in accordance with an applied voltage.
