More Information
Summary: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, a second emission part on the first emission part, and a first charge generation layer and a second charge generation layer between the first emission part and the second emission part. The first emission part includes a first organic layer, and the second emission part includes a second organic layer. A first thickness includes the first emission part and the first charge generation layer, and a second thickness includes the second emission part and the second charge generation layer. The first thickness is equal to or greater than the second thickness.
