ABSTRACT:
A ferroelectric liquid crystal composition having a long helical pitch and a light switching element having a quick response property are provided. This composition comprises (1) at least one member selected from the group consisting of liquid crystal compounds having a smectic C phase and no helical structure and liquid crystal compounds having only a nematic phase as a liquid crystal phase and no helical structure and (2) at least one chiral smectic liquid crystal compound.
