ABSTRACT:
A liquid crystal display includes a pair of support substrates, a liquid crystal layer held between the substrates, and pixel circuits that are arrayed in a matrix on one of the substrates and control the alignment state of liquid crystal molecules. Each pixel circuit includes first and second power terminals, first and second pixel electrodes that apply a liquid crystal drive voltage to the liquid crystal layer to create a substantially lateral electric field, and first and second drive transistors that have gate electrodes for receiving a video signal, that are connected between the first power terminal and the first pixel electrode and between the second power terminal and the second pixel electrode, respectively, and that cause the liquid crystal drive voltage determined by conductances that vary in accordance with the video signal, to be retained in a liquid crystal capacitance between the first and second pixel electrodes.
