Abstract
An organic light emitting display device includes an overcoating layer on a substrate; a first electrode on the overcoating layer; a bank layer on the overcoating layer and the first electrode, the bank layer including an opening through which the first electrode is exposed; a pattern layer having an island shape on the exposed portion of the first electrode; an organic emission layer on the first electrode and the pattern layer; and a second electrode on the organic emission layer.
Claims21
An organic light emitting display device, comprising:
- a substrate including a plurality of pixel areas having an emission area;
- a thin film transistor provided in each of the plurality of pixel areas;
