Patent ID: 8188478

Claim:
A display device comprising: a thin film transistor, the thin film transistor comprising: a gate electrode formed over a substrate; an insulating film formed over the gate electrode; a semiconductor film formed over the insulating film; a source electrode formed over the semiconductor film; and a drain electrode formed over the semiconductor film; a pixel electrode comprising a transparent conductive material, formed over the substrate, and connected to the drain electrode; a source wiring being continuous to the source electrode, formed over the insulating film; a gate wiring being continuous to the gate electrode, formed over the substrate; a passivation film formed over the source electrode and the drain electrode, the passivation film being in contact with a portion of the semiconductor film between the source electrode and the drain electrode; and a capacitor, the capacitor comprising: a capacitor wiring formed over the substrate, wherein the capacitor wiring comprises a same material as the gate electrode; the insulating film formed over the capacitor wiring; and the pixel electrode formed over the capacitor wiring with the insulating film interposed therebetween, wherein the capacitor wiring extends substantially in parallel with the gate wiring at least in a pixel portion, wherein the capacitor wiring is electrically connected to a terminal portion, and wherein the terminal portion is formed in an edge portion of the substrate.
