ABSTRACT:
A polymer having spontaneous polarization with the same codes as liquid crystal is introduced into a liquid crystal layer of the smectic liquid crystal cell so that the responding speed is improved (second liquid crystal cell). In another way, a polymer having spontaneous polarization with opposite codes to the liquid crystal is introduced into liquid crystal showing .tau.-V.sub.min characteristic so that a driving voltage is lowered (first liquid crystal cell). These polymers are previously added to a liquid crystal composite before injecting into the liquid crystal cell. In another way, after a photochemically polymeric monomer is added to the liquid crystal composite and the obtained product is injected into the liquid crystal cell, the monomer is polymerized by the projection of a light. Furthermore, the liquid crystal cell into which the polymer is introduced is heated again so as to show I phase and is cooled so that the tone display is realized.
