Abstract:
1. A light emitting display device comprising: a thin film transistor over a substrate; an interlayer insulating film over the thin film transistor; a wiring over the interlayer insulating film, wherein the wiring is electrically connected to the thin film transistor; a first electrode over the wiring, wherein the first electrode is electrically connected to the wiring; an inorganic insulating film over the first electrode, wherein the inorganic insulating film has an opening which reaches the first electrode; a rounded corner at the opening of the inorganic insulating film; an electroluminescent layer over the inorganic insulating film; and a second electrode over the electroluminescent layer, wherein a top surface of the first electrode has a first region overlapping with the inorganic insulating film and a second region not overlapping with the inorganic insulating film, wherein the second region is nitrided and the first region is not nitrided, and wherein the second region contains nitrogen at a rate of 20 to 50 atomic %.
