Abstract:
An active matrix device comprising:a pixel electrode formed over a substrate having an insulating surface; a signal line formed over said substrate; and a switching element operationally connected between said pixel electrode and said signal line, said switching element comprising: a crystalline semiconductor island formed over said substrate; a first channel region formed in said semiconductor island; a second channel region formed in said semiconductor island; a first impurity doped region in said semiconductor island between said first and second channel regions; at least two impurity doped regions in said semiconductor island contiguous to said first and second channel regions, respectively, wherein said at least two impurity doped regions have a same conductivity type as said first impurity doped region; first and second gate electrodes below said first and second channel regions, respectively, with a gate insulating film interposed therebetween wherein said first and second gate electrodes are connected to a same gate line.
