Abstract
In an active matrix liquid crystal display apparatus, the potentials of a source signal, the terminal of a storage capacitor other than the terminal connected to a pixel electrode, and a counter electrode are set so that the relationship between a potential difference from the potential of the other terminal of the storage capacitor to the potential of the counter electrode varies repeatedly. Further, the absolute value of a first voltage applied between the pixel electrode and the counter electrode when the potential difference is the same as that during writing of a charge to the pixel electrode, and the absolute value of a second voltage applied between the pixel electrode and the counter electrode when the potential difference is different from that during writing of a charge to the pixel electrode is determined to make the effective voltage applied to a liquid crystal capacitor during display of a predetermined gray-scale level by a moving image different from an effective voltage applied to the liquid crystal capacitor during display of the predetermined gray-scale level by a still image.
