Abstract
An antiferroelectric liquid crystal display comprises: an antiferroelectric liquid crystal display element which includes an antiferroelectric liquid crystal that is sandwiched between a pair of substrates having a plurality of scanning electrodes and signal electrodes deposited respectively on the opposing surfaces thereof; and a light source which successively emits a plurality of different colors of light. In the thus constructed antiferroelectric liquid crystal display, a scanning period (TS) during which the light source emits light of one of the plurality of colors is divided into two periods, of which the first period (SC) includes a selection period for determining a display state and a non-selection period for holding therethrough the display state selected during the selection period, and the second period (SC), constituting the remainder of the scanning period, includes a selection period for forcing the display state into a black display state and a non-selection period for holding therethrough the black display state selected during the selection period.
