ABSTRACT:
In a liquid crystal device wherein a bistable ferroelectric liquid crystal is sandwiched between display electrodes; a liquid crystal device and a driving method therefor characterized in that switching elements are disposed at respective intersection points between a plurality of scanning electrodes and a plurality of signal electrodes, and that at a juncture between said each switching element and one of said display electrodes, a control element is disposed by which when said switching element is off, an absolute value of a crest value of a voltage applied to said ferroelectric liquid crystal is held less than a threshold value (.vertline.V.sub.th .vertline.) of said ferroelectric liquid crystal.
