ABSTRACT:
A driving circuit includes a scanning-line driving circuit applying an on potential to sequentially drive scanning-lines, a data-line driving circuit that, when the on potential is applied to each scanning-line, turns each data-line potential to a potential difference corresponding to a density based on a counter electrode potential and a potential corresponding to the same writing polarity among the scanning-lines, and a storage capacitor driving circuit which, when the on potential is applied to the scanning-lines and the data-line potential corresponds to positive polarity writing, shifts the other storage capacitor electrode potential in each storage capacitor to a high level after an off potential is applied to the scanning-lines, and, when the on potential is applied to the scanning-lines and the data-line potential corresponds to negative polarity writing, shifts the other storage capacitor electrode potential to a low level after the off potential is applied to the scanning-lines.
