(54) | LIQUID CRYSTAL DISPLAY DEVICE |
(57) In a liquid crystal display device according to 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 jth row rises before the source signal voltages change to values that correspond to pixels
along the jth row. Next, the image write pulse of the gate signal supplied to a gate bus line that
corresponds to pixels along the jth row falls, and then the image write pulse of the gate signal supplied to a gate bus
line that corresponds to pixels along the kth row (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 jth row are inverted after the image write pulse of the gate signal supplied to a gate
bus line that corresponds to pixels along the kth row rises.
