Abstract
Abstract A liquid crystal apparatus comprises an active matrix substrate including a plurality of scanning lines and a plurality of signal lines, transistors arranged respectively at the crossings of the scanning lines and the signal lines and having the source region connected to the corresponding signal line and the gate region connected to the corresponding scanning line and pixel electrodes connected respectively to the drain regions of the transistors, an opposite substrate disposed oppositely relative to the active matrix substrate and a liquid crystal material filled in the space between the active matrix substrate and the opposite substrate. A source region is shared by each pair of adjacently located transistors and connected to the corresponding signal line.
