Abstract

A liquid crystal display has a liquid crystal layer, first and second electrodes, and a third electrode. The liquid crystal layer is inserted between the first and second electrodes to define liquid crystal cells. The third electrode is capacitively coupled with one of the first and second electrodes. A correction voltage for correcting distortion of a waveform for driving one of the first and second electrodes is applied to the third electrode, to keep an effective voltage applied to the liquid crystal cells unchanged and improve the display quality of the liquid crystal display. Therefore, the liquid crystal display of the present invention can correct distortion of a common voltage and prevent crosstalk.
