Abstract
A method for driving a liquid crystal display device is provided. The device includes a plurality of row electrodes to which a scanning signal is applied: a plurality of column electrodes disposed so as to cross the plurality of row electrodes, to which a display data signal is applied; and a liquid crystal layer interposed between one of the plurality of row electrodes and one of the plurality of column electrodes, for performing a display at a crossing portion of one of the plurality of row electrodes and one of the plurality of column electrodes in response to an effective value of a voltage applied across one of the plurality of row electrodes and one of the plurality of column electrodes, wherein gray-scale display data consisting of a plurality of bits is received, and a voltage of a display data signal selected per bit by a scanning signal is applied during a period in which weights are assigned to bits during one horizontal scanning period and a voltage applying timing is made different at at least one column electrode, whereby a gray-scale display is realized.
