Antiferroelectric liquid crystal display with liquid crystal layer structure control

摘要

An antiferroelectric liquid crystal display having: a temperature sensor for measuring the temperature of a liquid crystal panel (10); a heater (102) for heating the liquid crystal panel (10); and a heater control circuit (17) for controlling the temperature of the liquid crystal panel (10), wherein the liquid crystal panel (10), while being driven to produce a display, is maintained at a temperature at which smectic layer spacing in an antiferroelectric liquid crystal material sandwiched within the liquid crystal panel (10) becomes the smallest. In this antiferroelectric liquid crystal display, when the temperature of the liquid crystal panel (10), after power on, has reached the temperature at which the smectic layer spacing in the antiferroelectric liquid crystal material becomes the smallest, a layer structure control voltage waveform is applied to the liquid crystal panel (10).
