Abstract: Discussed is an organic light emitting display device for reducing a color defect or a color difference which occurs in the front or side of the organic light emitting display device. The organic light emitting display device can include a first electrode, a second electrode and an organic layer between the first electrode and the second electrode, the organic layer including at least one emission part. The organic layer is configured for a peak wavelength of an electroluminescence (EL) spectrum of the organic light emitting display device emitted from the at least one emission part to have a range from 10 nm less a predetermined peak wavelength to 10 nm more than the predetermined peak wavelength.

Abstract: Disclosed herein are an organic light-emitting diode and an organic light-emitting display device including the same. The organic light-emitting diode includes: a first electrode; a first light emitting structure disposed on the first electrode and including a first organic emissive layer; a second light emitting structure disposed on the first light emitting structure and including a second organic emissive layer; a third light emitting structure disposed on the second light emitting structure and including a third organic emissive layer; and a second electrode on the third light emitting structure, wherein a full width at half maximum (FWHM) of a peak wavelength of light emitted from each of the first organic emissive layer and the third organic emissive layer is within a range from 26 nm to 36 nm, inclusive.
