Abstract:
An active matrix device comprising:a semiconductor layer formed over a substrate; at least first and second thin film transistors formed with said semiconductor layer, each of said first and second thin film transistors including source, drain and channel regions formed in said semiconductor layer, and a gate electrode adjacent to said channel forming region; a pixel electrode formed over said substrate; a signal line formed over said substrate, electrically connected to said pixel electrode through said first and second thin film transistors in series; a capacitor forming electrode and a portion of said semiconductor layer and an insulating film interposed therebetween, wherein said portion of the semiconductor layer is disposed between a pair of impurity regions in said semiconductor layer, and said impurity regions have a same conductivity type as the source and drain regions of said first and second thin film transistors.
