Abstract
A ferroelectric liquid crystal device comprises a pair of opposite electrodes and a ferroelectric liquid crystal disposed between the electrodes. At least one of the opposite electrodes is coated with an insulating film having a thickness of 200 .ANG. or larger. The ferroelectric liquid crystal has a capacitance C.sub.LC measured in (nF/cm.sup.2) and a spontaneous polarization PS measured in (nC/cm.sup.2) and the insulating film has a capacitance Ci measured in (nF/cm.sup.2) wherein the magnitudes of C.sub.LC, Ps, and Ci satisfy the relationship of
