ABSTRACT:
A liquid crystal display which comprises an active matrix circuit board equipped with a plurality of transistors having a plurality of pixel electrodes arranged along a plurality of lines and rows and drains connected to these pixel electrodes, scanning lines for commonly connecting gates of the transistors arranged along the lines, and signal lines for commonly connecting sources of the transistors arranged along the rows, a substrate having a facing electrode, and a liquid crystal interposed between the active matrix circuit board and the substrate the liquid crystal display being constituted so that a voltage may be applied to regions of a conductive mode which is different from a conductive mode of the sources and the drains of semiconductor layers constituting the transistors.
