Patent ID: 6905907

Claim:
A method of manufacturing a light-emitting device, comprising: Forming a thin film transistor over a substrate; Forming an insulating layer over the thin film transistor; Forming a wiring over the insulating layer; Forming a conductor, which is electrically connected to the thin film transistor by the wiring, over the insulating layer, Forming an insulating film over the conductor, Polishing at least an upper portion of the insulating film by a chemical mechanical polishing method until at least an entire upper surface of the conductor is exposed, making an exposed upper surface of the conductor flush with a polished upper surface of the insulating film, where the upper portion of the insulating film covers the entire surface of the conductor, thus forming a first electrode and a leveled insulating layer, Forming an organic compound layer contacting the first electrode; and Forming a second electrode contacting the organic compound layer.
