Abstract
A liquid crystal display includes a liquid crystal display panel having a pixel matrix consisting of a plurality of pixels, a signal line driver, a row address line driving circuit, a row pixel counter circuit, a row address signal generating circuit, a column address line driving circuit, a column pixel counter circuit, and a column address signal generating circuit. Each pixel includes a liquid crystal unit, a storage capacitor, and a switching unit consisting of switching devices. The switching unit is turned on and off by a cooperation of a row address line and a column address line. While the switching unit is ON, an image signal is supplied from a signal line to a pixel electrode. This reduces write operations to pixels and thereby reduces the power consumption, and also improves the writing characteristic and the holding characteristic which differ from one pixel to another.
