PURPOSE:To improve displayed gradation characteristic by inserting ferroelectric liquid crystals between confronting substrates and holding the liquid crystals at specified three conditions. CONSTITUTION:When ferroelectric liquid crystals are inserted between confronting substrates having an oblique deposited inorg. material on the surface of the substrates, the liquid crystal molecules are stabilized at an intermediate third state having a twisted structure with a different angle between the normal of the layer of molecules. Accordingly, the liquid crystals in the liquid crystal element are held at the first state where the liquid crystal molecules are almost parallel to the substrate but are inclined rightwards against the normal of the molecule layer, at the second state where the liquid crystals are inclined leftwards, and the third state where the liquid crystal molecules are in the intermediate stage, permitting sufficient display of gradation by the intermediate state. Thus, the display performance of the gradation is improved.
