Abstract:
A liquid crystal display comprises picture elements each including a plurality of pixel electrodes (10,12,11,13) of different sizes. Each pixel electrode (10,12,11,13) is connected to a thin film transistor (20,21,22,23). To reduce flicker when displaying a half tone image, each thin film transistor (20,21,22,23) comprises a channel whose width is a function of the size of the corresponding pixel electrode (10,11,12,13). Preferably each thin film transistor (20,21,22,23) comprises a channel whose width is proportional to the size of the corresponding pixel electrode (10,11,12,13).
