ABSTRACT:
A method of driving an electro-optical device having a plurality of scan lines, data lines and pixels in which data written into and stored within the plurality of pixels is erased from the pixels sequentially rather than at the same time. A plurality of pulses supplied on the scan and data lines during the erasing period produces an erasing period for each scan line which is substantially the same. The effective voltage value of signal waveforms during the erasing period is less than the absolute magnitude of a holding signal waveform which maintains the data in the pixels until the erasing period begins.
