Abstract
Disclosed is an organic light emitting display device. The organic light emitting display device includes a first emission part between a first electrode and a second electrode and a second emission part on the first emission part. The first emission part includes a first hole transport layer and a first emission layer, and the second emission part includes a second hole transport layer and a second emission layer. A thickness of the second hole transport layer is greater than a thickness of the first hole transport layer.
