Abstract
In a display apparatus of a hold type represented by a TFT liquid crystal display, blurring of dynamic picture when the dynamic picture is displayed is improved. One frame is divided into dark fields and light fields. A dark brightness gradation voltage approaching to display of black as near as possible is generated in the dark fields and a light brightness gradation voltage for compensating the brightness reduced by the dark fields is generated in the light fields. At this time, low gradation voltages (VP to VP) or high gradation voltages (VP to VP) in the dark or light brightness gradation voltages are set to the same potential.
