Patent ID: 8293552

Claim:
A method for manufacturing a light-emitting device comprising: forming an etching-stop layer having an electric conductivity over an insulating surface; forming a first insulating film covering the etching-stop layer; etching the first insulating film to form an opening reaching the etching-stop layer; carrying out plating to form a conductive film over the etching-stop layer and at least in the opening; planarizing a surface of the conductive film to form a buried interconnection; forming a second insulating film containing aluminum over the first insulating film; forming a third insulating film over the second insulating film; forming a semiconductor layer over the third insulating film; forming a fourth insulating film over the semiconductor layer; forming a gate electrode over the fourth insulating film; forming a first line electrically connected to the semiconductor layer and a second line electrically connected to the buried interconnection; forming a first electrode; and forming a layer containing an organic compound over the first electrode and a second electrode over the layer containing the organic compound, wherein the first electrode is electrically connected to the first line.
