Patent ID: 6885027

Claim:
An active matrix type display device comprising: a first thin film transistor over a substrate; a pixel electrode electrically connected to the first thin film transistor; a second thin film transistor over the substrate, each of the first and second thin film transistors comprising at least source, drain and channel regions, a gate insulating film and a gate electrode; and a capacitor comprising a first electrode, a second electrode and a dielectric layer interposed therebetween wherein said capacitor is connected to one of the source and drain regions of the first thin film transistor and to one of the source and drain regions of the second thin film transistor, wherein the second electrode of the capacitor is formed in a same semiconductor layer as the source and drain regions of the first thin film transistor and the source and drain regions of the second thin film transistor are formed, and wherein the dielectric layer of the capacitor is formed on a same surface as the gate insulating films of the first and second thin film transistors.
