Abstract
In order to prevent a burn-in phenomenon from occurring in a liquid crystal, the present invention provides a display apparatus including a liquid-crystal display device employing the liquid crystal and a driving circuit. In an operation to drive the liquid-crystal display device, the driving circuit inverts the polarity of a signal voltage applied between pixel electrodes and a facing electrode, which are employed in the liquid-crystal display device, every frame period of a moving-image signal. In the operation to drive the liquid-crystal display device, the driving circuit also changes the phase of a control signal for inverting the polarity.
