Abstract
A display apparatus includes pixel electrodes, a counter electrode arranged facing the pixel electrodes, and liquid crystal cells held in a space between the pixel electrodes and the counter electrode. The optical characteristics of the liquid crystal cells change based on potential differences between the pixel electrodes and the counter electrode. The counter electrode includes row counter electrodes divided in accordance with rows of pixels. The display apparatus also includes a counter scanning circuit for sequentially scanning the row counter electrodes in accordance with a pixel row sequentially selected by a vertical scanning circuit and for applying a counter potential of one inverting polarity.
