Abstract:
1. An electronic device having at least one self-light emitting device comprising: a first semiconductor island formed on an insulating surface, said first semiconductor island having at least first and second impurity regions and a channel region therebetween; a second semiconductor island formed on said insulating surface, said second semiconductor island separated from said first semiconductor island; an insulating film formed on said first semiconductor island and said second semiconductor island; a gate electrode formed over said first semiconductor island with said insulating film interposed therebetween; a capacitor forming electrode formed over said second semiconductor island with said insulating film interposed therebetween, wherein said gate electrode and said capacitor forming electrode are formed in a same conductive layer and electrically connected to each other; and a light emitting element comprising a cathode, an anode and a light emitting material interposed between said cathode and said anode wherein one of said first and second impurity regions is electrically connected to one of said cathode and said anode.
