Abstract:
1. A liquid crystal display device comprising: a source signal line, a first gate signal line, a second gate signal line, a first pixel electrode, a second pixel electrode, a third pixel electrode and a fourth pixel electrode over a substrate; and a color filter formed at a side of the substrate, wherein a first and a second video signals are supplied to the first pixel electrode, wherein a third and a fourth video signals are supplied to the second pixel electrode, wherein a fifth and a sixth video signals are supplied to the third pixel electrode, wherein a seventh and a eights video signals are supplied to the fourth pixel electrode, wherein the source signal line is interposed between the first pixel electrode and the third pixel electrode, and between the second pixel electrode and the fourth pixel electrode, wherein the second gate signal line is interposed between the first pixel electrode and the second pixel electrode, and between the third pixel electrode and the fourth pixel electrode, wherein the first video signal is supplied to the first pixel electrode in a first frame period, wherein the second video signal having an opposite polarity to the first video signal is supplied to the first pixel electrode in a second frame period subsequent to the first frame period, wherein the third video signal having a same polarity as the first video signal is supplied to the second pixel electrode in the first frame period, wherein the fourth video signal having an opposite polarity to the first video signal is supplied to the second pixel electrode in the second frame period, wherein the fifth video signal having a same polarity as the first video signal is supplied to the third pixel electrode in the first frame period, wherein the sixth video signal having an opposite polarity to the first video signal is supplied to the third pixel electrode in the second frame period, wherein the seventh video signal having a same polarity as the first video signal is supplied to the fourth pixel electrode in the first frame period, wherein the eighth video signal having an opposite polarity to the first video signal is supplied to the fourth pixel electrode in the second frame period, wherein a frame frequency is 120 Hz or more, and wherein each of the first frame period and the second frame period is a period in which one image is displayed.
