Abstract
An organic light emitting display includes first and second electrodes facing each other on a substrate, a red light emitting layer, a green light emitting layer and a blue light emitting layer formed between the first and second electrodes, a hole-transporting layer formed between the first electrode and each of the red light emitting layer, the green light emitting layer and the blue light emitting layer, and an electron-transporting layer formed between the second electrode and each of the red light emitting layer, the green light emitting layer and the blue light emitting layer, wherein a gap between a photo-luminescence (PL) peak maximum of the red host of the red light emitting layer and a photo-luminescence (PL) peak maximum of the electron-transporting layer contacting the red light emitting layer is within ±25 nm.
