ABSTRACT:
A liquid crystal display includes a liquid crystal matrix panel for displaying information having a plurality of liquid crystal pixels which are arranged in a matrix and to which driving voltages are applied from X electrodes and Y electrodes, a driving circuit for supplying the driving voltages to the Y electrodes, and a circuit for superimposing a compensating voltage for masking waveform distortion of a liquid crystal driving voltage by constantly changing the waveform thereof on at least one of the X electrode driving circuit and the Y electrode driving circuit.
