Abstract: Disclosed is a liquid crystal display device and a method of driving the same, which prevent image-quality defects due to charge variation. In the method of driving the liquid crystal display device including a pixel consisting of first to third sub-pixels which share one data line and are connected to first to third gate lines, one sub-pixel is turned off on a per frame basis, another sub-pixel is charged with a polarity inverted data voltage for a first charge time including a charge time of the turned-off sub-pixel, and the other sub-pixel is charged with a data voltage having the same polarity as a previous data voltage for a second charge time less than the first charge time. The turned-off sub-pixel, the sub-pixel charged with the polarity inverted data voltage, and the sub-pixel charged with the polarity maintained data voltage alternately vary on a per frame basis.
