ABSTRACT:
An active matrix-type liquid crystal panel is driven for a motion picture display in a succession of frame periods to provide an improved motion picture quality without causing a lowering in luminance or contrast, or a display irregularity over the panel due to a signal transmission delay along the panel electrodes. In the driving method, each frame period is divided into a plurality of sub-frame periods including at least one preceding sub-frame period and a final sub-frame period so that said at least one preceding sub-frame period provides a total period which is shorter than the final sub-frame period; the active elements along the rows of pixels are sequentially selected row by row at respective selection periods in each sub-frame period; and the liquid crystal at each pixel is supplied with a voltage in a selection period of each preceding sub-frame period which is lower than a voltage applied to the liquid crystal at the pixel in the final sub-final period.
