Abstract
A method of driving the electro-optical device includes selecting a plurality of scanning lines in a predetermined order in each of first and second fields of one frame; when one of the plurality of scanning lines is selected in the first field, for each pixel located on the selected scanning line, supplying one of a positive voltage and a negative voltage as the data signal to one of the plurality of data lines associated with the pixel, the positive voltage having a positive polarity corresponding to a voltage higher than a predetermined reference potential and the negative polarity corresponding to a voltage lower than the predetermined reference potential; and when the one of the plurality of scanning lines is selected in the second field, for each pixel located on the selected scanning line, supplying the other one of the positive voltage and the negative voltage as the data signal to one of the plurality of data lines associated with the pixel. A ratio between durations of the first field and the second field of the one frame is adjustable.
