Abstract:
A light emitting device comprising:a first insulating layer comprising silicon nitride or silicon oxynitride; a second insulating layer comprising silicon oxynitride over said first insulating layer; a thin film transistor formed between said first insulating layer and said second insulating layer, said thin film transistor having a semiconductor layer comprising silicon, a gate insulating film, and a gate electrode; a third insulating layer comprising silicon nitride or silicon oxynitride over said second insulating layer; a fourth insulating layer comprising carbon over said third insulating layer; a light emitting element formed between said third insulating layer and said fourth insulating layer, said light emitting element comprising an anode, an organic compound layer, and a cathode comprising an alkali metal; and partition layers comprising an insulating material on said third insulating layer, wherein said light emitting element is formed between partition layers, wherein at least an edge of said anode or at least an edge of said cathode is covered with at least one of said partition layers, and wherein said partition layers are directly in contact with said third insulating layer and either said anode or said cathode.
