摘要:
A ferroelectric liquid crystal device having a pair of substrates each provided with voltage applying means, an orientation control layer formed on at least one of the substrates, and a layer of ferroelectric liquid crystal composition disposed between the pair of substrates, the ferroelectric liquid crystal composition comprising at least one compound (a) having an optically active group of the formula (I):
, at least one compound (b) which is reverse to the compound (a) in the direction of a helical pitch induced in a nematic phase and at least one liquid crystal compound (c) exhibiting a smectic C phase, the liquid crystal composition exhibiting at least a smectic C phase, smectic A phase and nematic phase.
