Summary: | An organic light emitting display according to an embodiment of the present invention includes a first light emitting part which is disposed between a first electrode and a second electrode and includes a first organic layer, a second light emitting part which is disposed on the first light emitting part and includes a second organic layer, and a first charge generation layer and a second charge generation layer between the first light emitting part and the second light emitting part. A first thickness including the first light emitting part and the first charge generation layer is greater than or equal to a second thickness including the second light emitting part and the second charge generation layer. So, poor color generated in each position of the organic light emitting display can be prevented.
