Abstract
A liquid crystal display (LCD) is improved. A driving method for a LCD which has a liquid crystal layer interposed between the first electrode and the second electrode so that voltages to be applied to pixels are changed, wherein voltage levels in a selection time in a Pulse Width Modulation (PWM) driving method are the same level between two successive column electrodes so as to obtain a color display or a gray scale display which corresponds to an intermediate voltage applied to a pixel.
