摘要： In each horizontal period, by switching ON switches respectively provided for three data signal lines for R, G and B in a group at the same time only in a predetermined period, the data signal lines in the group are preliminary charged to a predetermined potential at the same time before a data signal supply period. In a subsequent data signal supply period, respective switches of data signal lines for R, G and B are switched ON sequentially, to sequentially supply respective data for R, G and B to pixels on a scanning signal line as selected are supplied via data signal lines. As a result, in a display device driven by time-division based on a group of sequentially provided data signal lines, it is possible to suppress up-throw potential fluctuations when display.
