Patent ID: 7609247

Claim:
A driving circuit for a liquid crystal display device, which has adjacent scanning line groups each having a plurality of scanning lines, data lines, liquid crystal capacitors correspondingly provided intersections between the plurality of scanning lines and the data lines with liquid crystal interposed between a counter electrode and pixel electrodes, switching elements interposed between the data lines and the pixel electrodes, the switching elements being turned on when an on potential is applied to the scanning lines and being turned off when an off potential is applied to the scanning lines, and storage capacitors each having one storage capacitor electrode connected to the corresponding pixel electrode and the other storage capacitor electrode disposed to face one storage capacitor electrode, the driving circuit for a liquid crystal display device comprising: a scanning line driving circuit that applies the on potential to the plurality of scanning lines so as to sequentially drive the plurality of scanning lines; a data line driving circuit that, when the on potential is applied to each of the plurality of scanning lines by the scanning line driving circuit, turns the potentials of the data lines to a potential difference according to a density on the basis of a potential of the counter electrode and the potentials corresponding to the same writing polarity among the scanning lines belonging to each of the groups of scanning lines; and a storage capacitor driving circuit which, when the on potential is applied to the scanning lines in the scanning line groups and the potential of the data line corresponds to positive polarity writing, simultaneously provides a first potential, which shifts a potential of the other storage capacitor electrode in each of the storage capacitors to a high level after the off potential is applied to all of the scanning lines in one of the scanning line groups, to the other storage capacitor electrode corresponding to all of the scanning lines in the one of the scanning line groups, and, when the on potential is applied to the scanning lines and the potential of the data line corresponds to negative polarity writing, simultaneously provides the second potential, which shifts the potential of the other storage capacitor electrode in each of the storage capacitors to a low level after the off potential is applied to all of the scanning lines in the one of the scanning line groups, to the other storage capacitor electrode which corresponds to all of the scanning lines in the one of the scanning line groups.
