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.

An organic light emitting display apparatus, comprising:
- 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,
- wherein 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.
A method of manufacturing an organic light emitting display apparatus, the method comprising:
- providing a substrate;
- forming an organic layer having a first concave portion and a first convex portion on a surface of the substrate;
- forming a first electrode having a second concave portion and a second convex portion on a surface of the organic layer;
- forming a hole transport region on the first electrode;
- forming an emission layer on the hole transport region;
- forming an electron transport region on the emission layer;
- and
- forming a second electrode on the electron transport region, wherein, informing the first electrode having the second concave portion and the second convex portion on the surface of the organic layer, a vertical distance between the second concave portion and the second convex portion is formed to be less a vertical distance that between the first concave portion and the first convex portion.
