A combination of a bright and dark display pattern and a polarity pattern is used to drive a liquid crystal display device. In the bright and dark display pattern, bright display picture elements and dark display picture elements alternate with each other every one picture element in horizontal and vertical directions. In the polarity pattern, positive-polarity picture elements and negative-polarity picture elements alternate with each other every two picture elements in the horizontal and vertical directions. This driving method allows preventing a phenomenon in which a screen becomes whitish when viewed from any oblique angle (i.e., washing out), that is, what the effect of HT technique based on time division is aiming at, while preventing the occurrence of flicker and burn-in on the screen. Moreover, the driving method enables coarseness-free excellent display, because the bright display picture elements and the dark display picture elements alternate with each other every one picture element.
