Claim 0:
1. An organic light emitting display device, comprising:
a substrate;
a first electrode disposed on the substrate;
an emission layer disposed on the first electrode;
a second electrode formed on the emission layer;
a first organic layer disposed on the second electrode;
a first inorganic layer disposed on the first organic layer; and
at least one second organic layer and at least one second inorganic layer disposed on the first inorganic layer,
wherein:
the first organic layer is spaced apart from the substrate;
a refractive index of the first inorganic layer is lower than a refractive index of the first organic layer; and
in a cross-sectional view, the first inorganic layer is contacted by at least one of the at least one second organic layer and the at least one second inorganic layer.
