Abstract
To keep down deterioration in picture quality caused by an AC driving method to enable image display with high quality to be achieved. In the invention, each of the pixels in a first frame just after the phase inversion for a predetermined starting time period is driven so that each of the pixels would be in a driving state of the polarity opposite to the polarity in the driving state in a last frame before the phase inversion, and then, each of the pixels is driven so that each of the pixels would be in a driving state of the polarity same as the polarity in the driving state in a last frame before the phase inversion when the driving circuit changes a driving state of each of the pixels from a positive polarity to a negative polarity or from the negative polarity to the positive polarity in every m (m≧1) frame and inverses a phase of the driving state of each of the pixels in every N (N≧m) frame wherein it is assumed that an image voltage having a potential higher than an opposite voltage applied to the opposite electrode is applied to the pixel electrode in a driving state of the positive polarity and that an image voltage having a potential lower than the opposite voltage applied to the opposite electrode is applied to the pixel electrode in a driving state of the negative polarity.
