    摘要： In a driver circuit which controls the supply of charge to cells each of which can store a charge, the EMI (Electro Magnetic Interference) which occurs at the time of performing the charge sharing driving can be reduced. A preceding conduction means (SW13) which is controlled in response to a clock signal (CLK1) makes an output signal line corresponding to a first circuit which has positive polarity of a potential higher than a reference potential and an output signal line corresponding to a second circuit which has negative polarity of a potential lower than the reference potential electrically conductive with each other. After a lapse of a predetermined time, a succeeding conduction means (SW23) which is controlled in response to a clock signal (CLK2) makes an output signal line corresponding to a third circuit which has the positive polarity and an output signal line corresponding to a fourth circuit which has the negative polarity electrically conductive with each other.

    摘要： 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.
