Claim:
1. An organic light emitting display device comprising: a first substrate; a thin film transistor disposed on the first substrate; a first electrode electrically coupled to the thin film transistor; a pixel defining layer disposed on the first substrate and the first electrode to define unit pixels; a plurality of organic light emitting structures disposed on the first electrode, wherein the organic light emitting structures comprise a first organic light emitting structure, a second organic light emitting structure and a third light emitting structure; a second electrode which covers the first through third organic light emitting structures and the pixel defining layer; a metamaterial layer disposed on the second electrode corresponding to the organic light emitting structures; an encapsulation member which covers the second electrode and the metamaterial layer; and a second substrate disposed on the encapsulation member opposite to the first substrate.
