A matrix liquid crystal display using an antiferroelectric liquid crystal prevents the displayed image from tailing off. The liquid crystal display includes a liquid crystal panel, a temperature sensor, a control unit, a scanning electrode driver circuit, and a signal electrode driver circuit. When the temperature of the liquid crystal panel is detected by the temperature sensor, the control unit increases or reduces the de-select period according to the detected temperature. The scanning electrode driver circuit and the signal electrode driver circuit serve to drive scanning electrodes and signal electrodes, respectively included in the liquid crystal panel according to control signals from the control unit and from a level converter. These control signals include a signal indicating the controlled de-select period. Thus, the controlled de-selected period is secured.
