Abstract: An organic light emitting display apparatus includes a substrate, an organic layer on the substrate, wherein the organic layer includes a first concave portion and a first convex portion on a surface thereof, a first electrode on the organic layer, wherein the first electrode includes a second concave portion and a second convex portion on a surface thereof, a second electrode on the first electrode, and an emission layer between the first and second electrodes. A vertical distance between the second concave portion and the second convex portion is less than that between the first concave portion and the first convex portion.
