Abstract:
A liquid crystal display device comprising:a first substrate on which pixel electrodes and active elements connected to said pixel electrodes are arranged in a matrix pattern;a second substrate on which a common electrode is formed facing said pixel electrodes;a liquid crystal layer formed by sealing, between said first and second substrates, an antiferroelectric liquid crystal which exhibits a chiral smectic phase while said liquid crystal is in a bulk state; andalignment films arranged each on one of opposite surfaces of said first and second substrates and having aligning forces by which liquid crystal molecules are aligned in a state in which there is substantially no correlation in molecular order between adjoining smectic layers in said liquid crystal layer, and by which a director of said liquid crystal layer is set substantially coincident with a direction of a normal line of said smectic layers; andmeans for changing the director of said liquid crystal layer by applying a voltage between said pixel electrodes and said common electrode.
