ABSTRACT:
A liquid crystal display is provided with a dummy-capacity driver for applying dummy capacities to scanning lines, in accordance with the number of on-state display elements and the number of off-state display elements in each scanning line. This arrangement makes it possible to suppress distortions that tend to appear in a waveform of the driving voltage upon inversion of the polarity. Thus, it becomes possible to obtain liquid crystal images of high picture quality with virtually no crosstalk when displaying any pattern.
