A driving method of a display device for expressing gray scales by a time gray scale method is provided where one frame is divided into multiple sub-frames, so that both the aperture ratio and the duty ratio can be maintained high while the power consumption can be suppressed low. The order of sub-frames is set to be different for each group having multiple pixel rows, and a data writing period of each group having the multiple pixel rows is set to be shorter than a data holding period of a sub-frame which corresponds to the least significant bit. While pixel rows belonging to a certain group are scanned, pixel rows belonging to the other groups are all in the data holding period. Accordingly, the driving frequency of data lines can be suppressed low and the power consumption can be reduced.
