Patent ID: 7309958

Claim:
A light emitting device comprising: a substrate; a cathode layer and an anode layer spaced apart by a predetermined distance on said substrate; an electron transfer layer and a light emitting layer sequentially stacked on said cathode layer; a current control unit controlling current flow between said cathode layer and said anode layer, said current control unit being formed between said cathode layer and said anode layer; a hole transfer layer spaced apart from said current control unit and connecting said light emitting layer and said anode layer; a protective layer formed on said hole transfer layer; a first insulating layer sealed by said protective layer and contacting outer surfaces of the layers stacked on said cathode layer; a second insulating layer surrounding a portion of said current control unit to which an external voltage is applied; and a third insulating layer formed on said substrate adjacent to said anode layer, said third insulating layer contacting at least the outer surface of said anode layer and being sealed by said protective layer.
