ABSTRACT:
In the case of supplying voltage to a common electrode which faces a pixel electrode through electro-optical substance while changing the voltage from a first low-potential-side voltage to a first high-potential-side voltage, a second high-potential-side voltage, which is higher than the first high-potential-side voltage, is supplied to the common electrode instead of the first low-potential-side voltage, and the first high-potential-side voltage is then supplied to the common electrode. One of the first high-potential-side voltage and a first intermediate voltage, which is lower than the first high-potential-side voltage but higher than the first low-potential-side voltage, may be supplied to the common electrode before supplying the second high-potential-side voltage to the common electrode.
