Abstract
In a liquid crystal display device according to one embodiment of the present invention, when the polarities of the source signal voltages do not change over a plurality of horizontal scanning periods, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the jrow rises before the source signal voltages change to values that correspond to pixels along the jrow. Next, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the jrow falls, and then the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the krow (j≠k) rises. The polarities of the storage capacitor signal voltages applied to storage capacitor bus lines that correspond to sub-pixels of pixels along the jrow are inverted after the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the krow rises.
