ABSTRACT:
A method for driving a ferroelectric liquid crystal panel in which a ferroelectric liquid crystal is disposed between a plurality of scanning and signal electrodes, and a select or a non-select voltage is applied to the scanning electrode whereas a rewriting or a holding voltage is applied to the signal electrode to change the display of each pixel, the method including: dividing all the scanning electrodes into a plurality of groups composed of a plurality of scanning electrodes; selecting a group whose display is to be changed; applying the select voltage to the scanning electrodes of the selected group at once; applying the rewriting voltage to the signal electrodes corresponding to the pixels whose displays are to be changed; applying the select voltage to each scanning electrode of the selected group successively; and applying the rewriting voltage to the signal electrodes corresponding to the pixels whose liquid crystal is to be placed in a second stable state.
