Abstract
Provided is an organic light emitting diode including a first electrode layer, a second electrode layer opposing the first electrode layer, a first light emitting layer between the first and second electrode layers to generate a first light having a first wavelength, a second light emitting layer between the first light emitting layer and the second electrode layer to generate a second light having a second wavelength which is longer than the first wavelength, and a charge generating layer between the first and second light emitting layers. The first and second lights are emitted through the second electrode layer. An optical length between the first and second electrode layers is substantially the same as a fourth resonant distance of the first light.
