ABSTRACT:
A liquid crystal display with improved gray-scale display. The liquid crystal display includes a plurality of pixel areas, each including first and second substrates disposed opposite each other and a liquid crystal layer interposed therebetween. A first pixel electrode and a first pixel driving device electrically connected thereto are formed on part of the first substrate. A second pixel electrode and a second pixel driving device electrically connected thereto are formed on part of the first substrate. A common electrode is formed on the interior of the second substrate. The first and second pixel driving devices have mutually different ON currents, resulting in the first and second pixel electrodes having mutually different voltages.
