Abstract
A liquid crystal display includes a liquid crystal display panel including a signal side substrate having an arrangement of a plurality of signal electrodes, a scanning side substrate positioned opposite to the signal side substrate and having an arrangement of a plurality of scanning electrodes crossing the plurality of signal electrodes, a liquid crystal layer positioned between the signal side substrate and the scanning side substrate, and a signal side driving circuit and a scanning side driving circuit for applying driving pulse voltage signals for displaying data to the plurality of signal electrodes and the plurality of scanning electrodes, respectively for driving these electrodes. When data is displayed, at least one of the driving pulse voltage signals is provided with a correction pulse voltage signal such that the effective voltage value of each part of the liquid crystal display panel attains an optimum level. The correction is achieved by adjusting the pulse width of the correction pulse voltage signal. As a result, unevenness in display quality may be improved without crosstalk.
