Abstract
An organic light emitting display includes a red light emitting layer, a green light emitting layer and a blue light emitting layer formed between first and second electrodes, a hole-transporting layer formed between the first electrode and each of the red, the green and the blue light emitting layers, and an electron-transporting layer formed between the second electrode and each of the red, the green and the blue light emitting layers, wherein at least one light emitting layer of the red, the green and the blue light emitting layers includes a first light emitting layer including a light emitting host and a light emitting dopant, and a second light emitting layer which is formed between the first light emitting layer and at least one of the electron-transporting layer and the hole-transporting layer, and includes the light emitting dopant.
