ORGANIC LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DEVICE INCLUDING THE SAME

Abstract:

An organic light emitting diode includes a first electrode; a second electrode facing the first electrode; and a first emitting material layer including a first compound, a second compound and a third compound and positioned between the first and second electrodes, wherein an onset wavelength of the second compound is greater than an onset wavelength of the first compound and is smaller than an onset wavelength of the third compound, wherein a maximum emission wavelength of the second compound is smaller than a maximum emission wavelength of the first compound, and a maximum emission wavelength of the third compound is equal to or smaller than a maximum emission wavelength of the first compound, and wherein a full width at half maximum of each of the second and third compounds is smaller than a full width at half maximum of the first compound.
