Abstract
A liquid crystal display device includes a display panel including row electrodes and column electrodes which cross the row electrodes. Display dots are formed at points where the column electrodes cross the row electrodes. A column electrode driver drives each of the column electrodes in accordance with display data to be displayed on the display dots. A waveform generator generates at least four different sets of waveforms. A row electrode driver drives the row electrodes by applying to the row electrodes respective voltages having respective ones of the waveforms in a selected one of the at least four different sets of waveforms, the selected one changing after each frame period. The display data is displayed on the display panel in accordance with the driving of the row electrodes by the row electrode driver and the driving of the column electrodes by the column electrode driver.
