The first pixel area has a first pixel electrode to which an image signal is applied, the image signal having a potential alternately switching between a positive polarity and a negative polarity with reference to a first central potential. The second pixel area includes a second pixel electrode to which a first driving potential is applied, the first driving potential having a potential alternately switching between a positive polarity and a negative polarity with reference to a second central potential, the first central potential and the second central potential having a potential difference set therebetween. Therefore, ionic impurities can be efficiently swept from the first pixel area to the second pixel area.
