Abstract
A liquid crystal display is provided with: a liquid crystal panel having a liquid crystal layer that is disposed between signal electrodes and scanning electrodes, a signal-side driving circuit which applies binary voltages representative of data to be displayed on the liquid crystal panel to the signal electrodes, a scanning-side driving circuit which successively applies scanning voltages to the scanning electrodes, a control circuit which controls the signal-side driving circuit so that rounded waveforms of voltages to be respectively applied to the signal electrodes are made virtually constant, and a compensation circuit which eliminates voltage distortions that are induced with respect to non-selected scanning electrodes, when the signal-side driving circuit is controlled. With this arrangement, it becomes possible to positively reduce the two types of crosstalk and also to achieve liquid crystal displays which have high display quality and are capable of making less conspicuous flickers and beats due to irregularly distorted waveforms which still remain slightly.
