Abstract: Discussed is an organic light emitting display device. The organic light emitting display device according to an embodiment includes a first electrode and a second electrode on a substrate to be opposite to each other and at least three emission parts between the first electrode and the second electrode. A first distance between the substrate and the first emission layer, a second distance between the first emission layer and the second emission layer, a third distance between the second emission layer and the third emission layer, and a fourth distance between the third emission layer and the second electrode are different from each other.
