Abstract
A ferroelectric liquid crystal cell comprising a ferroelectric liquid crystal having an antiferro-electric phase (S.sub.m C.sub.A.sup.*) or its composition and a pair of substrates having electrodes and holding said liquid crystal or its composition therebetween, characterized in that the layer structure of said liquid crystal in the antiferro-electric phase (S.sub.m C.sub.A.sup.*) has once been changed from a chevron structure to a bookshelf structure by application of a voltage to the electrodes.
