An organic light emitting display is provided. According to an embodiment of the present invention, the organic light emitting display is an organic light emitting display comprising a first sub pixel, a second sub pixel, and a third sub pixel of different colors with each other, and includes: a substrate; a first electrode arranged on the substrate; a second electrode arranged to face the first electrode on the first electrode; and an organic light emitting layer arranged between the first electrode and the second electrode, and comprises a fist organic light emitting layer, a second organic light emitting layer and a third organic light emitting layer. The third organic light emitting layer is arranged on the first electrode in common to the first sub pixel, the second sub pixel and the third sub pixel. The first organic light emitting layer is arranged on the first sub pixel, and the second light emitting layer is arranged on the third light emitting layer in the first sub pixel, the second sub pixel and the third sub pixel. A middle layer is arranged between the first organic light emitting layer and the third organic light emitting layer in the first sub pixel, and between the second organic light emitting layer and the third organic light emitting layer in the second sub pixel. A hole transportation layer is formed between the first organic light emitting layer and the middle layer in the first sub pixel, and between the second organic light emitting layer and the middle layer in the second sub pixel. |
