Abstract
A liquid crystal display device includes a liquid crystal panel having a plurality of scanning electrodes including first and second scanning electrodes, a plurality of signal electrodes including a first signal electrode, and a liquid crystal layer. A display is generated based on display data including first and second display data. The liquid crystal display device further includes a scanning electrode driver which outputs a scanning voltage to the first scanning electrode in a first scanning period and outputs a scanning voltage to the second scanning electrode in a second scanning period following the first scanning period. A signal electrode driver outputs a first voltage corresponding to the first display data to the first signal electrode in the first scanning period and outputs a second voltage corresponding to the second display data to the first signal electrode in the second scanning period. The signal electrode driver compares the first display data and the second display data and, when the first display data and the second display data are different, outputs a third voltage for correcting a reduction of an effective voltage of the second voltage for a correction duration in the second scanning period.
