CONSTITUTION:A driving pulse is applied between the transparent electrodes of the ferroelectric liquid crystal element to select one uniform state with the pulse whose voltage is -V0 once and then a pulse voltage V having the opposite polarity is applied to select a liquid crystal array state again, so that the transmissivity of the ferroelectric liquid crystal element changes in the order of one uniform state, the twist state, and the other uniform state as the reselect voltage V increases. Further, liquid crystal molecule array areas in the uniform states and twist state coexist between reselect voltages V1 and V2, and V3 and V4 to obtain the half-tone display. Consequently, the half-tone display which is continuous within the voltage range of V1 - V2 is obtained in switching mode wherein the twist state is selected after the uniform state is selected.
