Abstract
The motion picture quality of liquid crystal display apparatus is improved by placing a non-display period depending on the responsiveness of the liquid crystal and a backlight source. For this purpose, a sub-period is set, within one frame period, for displaying a luminance corresponding to prescribed picture data so as to provide a time integral of luminance corresponding to a maximum luminance not exceeding a certain threshold, and another sub-period for displaying a lower luminance is placed in the same one frame period.
