Claim Text:
1. An organic light emitting display device comprising: a substrate including a first active area and a dummy area; a plurality of first electrodes on the substrate; a first bank pattern overlapping edges of each first electrode and exposing a part of an upper surface of each first electrode; a second bank pattern on the first bank pattern within the first active area; a third bank pattern on the first bank pattern within the dummy area in the same layer as the second bank pattern; a first organic emission layer on an exposed upper surface of the first electrode within the first active area; a second organic emission layer on the exposed surface of the first electrode within the dummy area, wherein the second organic emission layer covers a larger area of the first electrode than the first organic emission layer; and a second electrode on the second and the third bank patterns and the first and the second organic emission layers, wherein a first opening in the first active area defined by the first bank pattern is smaller than a second opening in the dummy area defined by the third bank pattern.
