ABSTRACT:
An active matrix liquid crystal panel includes a plurality of thin film transistors respectively arranged adjacent to pixel electrodes, and a plurality of auxiliary capacitances. Each transistor has a semiconductor active layer, a pair of source and drain electrodes, and a gate electrode opposing the active layer via a gate insulating film. Each auxiliary capacitance has upper and lower electrodes, and a dielectric layer sandwiched between the upper and lower electrodes. The gate electrode, the lower electrode, and an address line respectively have portions formed of a common refractory metal film arranged on the insulating surface of a support substrate. The source and drain electrodes, the upper electrode, and a signal line respectively have portions formed of a common Mo film. Each pixel electrode has a portion formed of an ITO film. Each auxiliary capacitance further has an intervening layer between the dielectric layer and the upper electrode. The intervening layer has a portion formed of a semiconductor film common to the active layer of the transistor.
