<p>A liquid crystal optical modulation element is disclosed. The modulation element comprises two transparent substrates (51, 52) positioned so as to face each other; a transparent electrode (61, 62) provided on the facing surface of the transparent substrates (51, 52); a transparent insulating/orientation control layer (91, 71; 92,72) provided on each of the facing surfaces of the transparent electrodes (61, 62), having insulating properties and orientating the liquid crystal (11) molecules in the proximity thereof in a preferential direction substantially parallel to the surfaces of the substrates (51, 52); a liquid crystal (11) layer exhibiting ferroelectricity, sandwiched between the insulating/orientation con- trot layers (91, 71; 92, 72); and means (41, 42) for polarizing tight passing through said liquid crystal (11) layer.</p><p>The liquid crystal optical modulation element of the : present invention is produced by the steps of coating transparent electrodes (61, 62) onto transparent substrates (51, 52); coating polyimide films (91, 92) so as to cover the transparent electrodes (61, 62); rubbing the polyimide coating films (91, 92); positioning the transparent substrates (51, 52) parallel to each other so that the rubbed polyimide coating films (91, 92) face each other so that a liquid crystal cell is thereby assembled; introducing a liquid crystal (11) exhibiting ferroelectricity into the cell thus formed and sealing the cell; and providing polarizers (41, 42) on the external surfaces of the substrates (51, 52).</p> |
