Abstract
A control section of a driving device for a liquid crystal display device element selects one dividing ratio pattern from at least two different predetermined dividing ratio patterns, and a 1-line selection period is divided into a plurality of timing segments by a timing signal outputted from a timing generating circuit based on the selection result. A picture element is charged by having a predetermined voltage applied during at least one timing segment out of the plurality of timing segments depending on whether the picture element is ON or OFF, and the charge supplied to the picture element is discharged during at least another timing segment in accordance with the ON/OFF state of the picture element.
