Abstract

An active matrix liquid crystal display device, comprising an array of pixels (10); each pixel (10) comprising a liquid crystal element comprising a respective pixel electrode (18) and a corresponding part of a liquid crystal layer; each pixel (10) further comprising a storage capacitor (20); wherein the device is arranged to reset the liquid crystal element by coupling a voltage onto the pixel electrode (18) of the pixel (10) using the storage capacitor (20) of the pixel (10). The reset of the liquid crystal element may be combined with switching of a backlight (70).
