ABSTRACT:
In the method for driving a liquid crystal display device which has a plurality of picture elements or “pixels” and a drive circuit for outputting to each pixel a gradation voltage selected from among M (M≧2) gradation voltages, the polarity of a gradation voltage that is outputted from the drive circuit to each pixel is inverted for every N (N≧2)-line group, while letting the voltage value of an m (1≧m≧M)-th gradation voltage to be outputted from the drive circuit to each pixel be different between the time when outputting it to the pixels on the first line immediately after the polarity inversion and the time when outputting it to the pixel on a line which is subsequent to the first line, immediately after the polarity inversion, and whose polarity is not inverted.
