Abstract

A method for driving an antiferroelectric liquid crystal cell suitable for a simple-matrix display, "utilizing" third state .fwdarw.uniform state and "uniform state.fwdarw.third state" switchings, in which the uniform state to third state switching is done within a memory time of uniform to third state switching. The uniform states are employed as the light and dark states.
