Abstract
In a liquid crystal device, pixel electrodes and a common electrode that opposes the pixel electrodes on another side of a liquid crystal layer are formed in a display region serving as a first region, and dummy pixel electrodes serving as first electrodes are formed in a dummy pixel region serving as a second region. A driving method for the liquid crystal device applies a voltage that is lower than a threshold voltage at which the transmissibility of liquid crystals changes between the dummy pixel electrodes and the common electrode. Accordingly, the dummy pixel electrodes can function as an electricity parting portion and ionic impurities can be pulled from the display region to the dummy pixel electrodes.
