摘要： In one embodiment of the present invention, when a still image is displayed, applied voltages respectively corresponding to a total of n (n being an integer of not less than 4) types of gradation 0 to (n−1) are outputted to pixels. On the other hand, when a moving image is displayed, an applied voltage corresponding to a predetermined gradation m (1≦m≦(n−2)) is applied to the pixels instead of applied voltages respectively corresponding to gradations of less than the predetermined gradation m.
