Abstract:
A method of driving an electro-optical device including a plurality of scanning electrodes and a plurality of signal electrodes, said plurality of scanning electrodes and said plurality of signal electrodes crossing each other, said plurality of scanning electrodes being organized into groups in which each group consists of a number of scanning electrodes which are simultaneously selected, and selection of scanning electrodes being performed group by group, the method comprising:applying signal voltages to said signal electrodes, wherein the signal voltages applied to said signal electrodes including a maximum signal voltage and a minimum signal voltage; applying scanning voltages to said scanning electrodes, the scanning voltages having an amplitude equal to an amplitude of the signal voltages applied to said signal electrodes, the scanning voltages applied to said scanning electrodes including a non-selection voltage, a first selection voltage which is positive with respect to said non-selection voltage, and a second selection voltage which is negative with respect to said non-selection voltage; and setting the maximum signal voltage and the minimum signal voltage to be equal to said first selection voltage and said second selection voltage.
