    摘要： An organic light emitting diode (OLED) is described, which comprises at least one emitting material (EML) disposed between two electrodes. The EML can comprise a first emitting material layer having a first compound and a second compound of phosphorescent material, and a second emitting material layer having a third compound with triplet-triplet-annihilation property and a fourth compound. Further, an organic light emitting device can comprise the OLED. With the luminous materials with adjusted excited singlet/triplet energy levels, the intensities of emission peaks and full-width at quarter maximum applied into the emitting material layer, the driving voltage of the OLED can be reduced and the luminous efficiency, blue index and luminous lifespan of the OLED can be enhanced.
