A device for driving a liquid crystal display device including common electrodes and segment electrodes to which scanning signals and display signals whose polarities are changed every half period of a frame signal are applied respectively. This device comprises a common electrode driving circuit, a segment electrode driving circuit, a display period control circuit for supplying the common electrode driving circuit and the segment electrode driving circuit with clock pulses, display data corresponding to an image to be displayed, and the frame signals during a display period in which an operation for displaying an image on the liquid crystal device is to be performed, and a non-display period control circuit for supplying the common electrode driving circuit and the segment electrode driving circuit with frame signals during a non-display period in which the displaying operation of an image on the liquid crystal display device is to be stopped.
