Abstract: The liquid Crystal Device which comprises (a) pair of transparent substrates held facing each other with a gap normally employed such devices, (b) each substrate having on one of its surfaces a coating of a transparent electrically conducting material which serves as an electrode, (c) an additional layer of a coating of a polymer on the resulting substrate, (d) a dual frequency addrerssable nematic liquid crystal being filled in the gap between the coated surfaces of the substrates thereby forming a cell, and (e) the cell incorporated between a pair of crossed polarisers.
