A driving apparatus suitable as, e.g., an electrode plate for an optical modulation device such as a liquid crystal device, comprises a conductor film, a plurality of voltage supply lines electrically connected to the conductor film respectively by the medium of a resistor, means for simultaneously applying a voltage signal to at least two voltage supply lines among the plurality of voltage supply lines, and means for changing a potential level provided to the conductor film defined between the at least two voltage supply lines.
