Abstract: An organic light emitting diode can include a first electrode and a second electrode; an organic light emitting layer between the first electrode and the second electrode; and a auxiliary light emitting layer between the first electrode and the organic light emitting layer or between the organic light emitting layer and the second electrode, wherein a difference between a main peak wavelength of light emitted from the organic light emitting layer itself and a main peak wavelength of light out-coupling between the first and second electrodes is within a predetermined range.

Abstract: An organic light-emitting device and an organic light-emitting display device using the same are discussed. In a structure in which emission layers that emit light having the same color are provided in a plurality of stacks, the emission layers have different properties such that the light emission efficiencies of the stacks are made uniform, whereby the lifespan of the organic light-emitting device is increased through charge balance.
