Patent ID: 7701426

Claim:
A display device comprising: a plurality of data signal lines divided into a plurality of groups, each group being made up of sequentially provided data signal lines; a plurality of scanning signal lines; a data output circuit for outputting data signals to the plurality of data signal lines; a plurality of pixels, provided respectively at intersections of said plurality of data signal lines and said plurality of scanning signal lines; and a plurality of switches provided for each group of data signal lines, wherein respective data output sides of said plurality of switches are connected to respective ends on one side of said plurality of data signal lines, and respective data input sides of said plurality of switches are mutually connected to the data output circuit, and said plurality of switches output the data signals to each group of data signal lines by time-division in each horizontal scanning period and turn ON respective groups of data signal lines at the same time to simultaneously output the data signals, wherein a polarity of each of the data signals is inverted for each frame, and the data output circuit charges the data signal lines in each group to a predetermined potential only in a vertical blank period, and the switches are conducted also in a period in which the data output circuit charges the data signal lines.
