1. An organic light emitting display device comprising:
a substrate; a plurality of organic light emitting elements disposed on the substrate, the plurality of organic light emitting elements including a first organic light emitting element, a second organic light emitting element and a third organic light emitting element; an encapsulating member encapsulating the plurality of organic light emitting elements; graded functional layers disposed on the encapsulating member, the graded functional layers including convex lenses and concave lenses disposed on pixel regions, and connecting portions connecting adjacent convex lenses; and a black matrix disposed on each of the connecting portions of the graded functional layers, wherein the concave lenses are disposed closer to the encapsulating member than the convex lenses, wherein the graded functional layers comprise a low refractive film and a high refractive film having a refractive index higher than that of the low refractive film and on the low refractive film, wherein the convex lenses are formed of the high refractive film, the convex lenses including a first convex lens disposed on the first organic light emitting element, a second convex lens disposed on the second organic light emitting element and a third convex lens disposed on the third organic light emitting element, wherein each of the first convex lens, the second convex lens and the third convex lens has an upper region disposed above an upper surface of the connecting portions and a lower region disposed below a lower surface of the connecting portions, and wherein the third convex lens has a flat portion directly on its lower region.
