    摘要： A ferroelectric liquid crystal element comprises a ferroelectric liquid crystal and a pair of substantially parallel substrates having opposite surfaces between which the ferroelectric liquid crystal is sealed. The substrates are provided with electrodes to which voltages are applied, and are subjected to one axis orientation treatment so as to orient the ferroelectric liquid crystal. The ferroelectric liquid crystal has an orientation state represented by the following condition: &thgr; &thgr;a>{fraction (&thgr;/2)}.

    摘要： A ferroelectric liquid crystal device is by disposing between a pair of substrates a ferroelectric liquid crystal composition showing a phase transition series of isotropic.fwdarw.chiral nematic phase (N.sup.*).fwdarw.chiral smectic C phase on temperature decrease. The alignment state of the liquid crystal is improved by forming alignment control films of mutually different materials on the pair of substrates. The alignment state is improved especially when the liquid crystal composition is formulated to show a helical pitch in N.sup.* phase which exceeds three times the spacing between the pair of substrates.

    摘要： A chiral smectic liquid crystal composition is formed by including at least one species of a mesomorphic compound represented by the following formula (I): ##STR1## wherein X denotes F, Cl, Br, CF.sub.3, NO.sub.2 or CN; Y denotes a single bond, ##STR2## --CH.sub.2 O-- or --OCH.sub.2 --; and R denotes a linear or branched alkyl group having 1-20 carbon atoms optionally substituted. The composition shows improved switching characteristics and, when used in combination with an alignment film providing a high pre-tilt angle, provides an increased contrast at a large drive margin and with little tendency of monostabilization of a memory state.
