Abstract: An organic light emitting diode (OLED) includes at least one emitting material layer (EML) disposed between two electrodes and including a first compound of a pyrimidine-based organic compound substituted with at least one electron-withdrawing group and a second compound of an organic compound having a tetracene-based core. The OLED can be included in an organic light emitting device. The first compound and the second compound can be the same emitting material layer or adjacently disposed emitting material layers. The OLED can lower its driving voltage and improve its luminous efficiency utilizing the advantages of the first and second compounds by adjusting energy levels between the first and second compounds.

Abstract: The present disclosure relates to an organic light emitting diode and an organic light emitting device having the diode. An organic light emitting diode including a plurality delayed fluorescent materials with specific energy levels and an organic light emitting device including the diode is disclosed. When the plurality delayed fluorescent materials with specific energy levels are applied in an emitting material layer, it is possible to minimize the energy loss or exciton quenching during luminescent process, to prevent the diode from reducing lifetime caused by the exciton quenching, and to make charges being injected into the emitting material layer in balance. When the emitting material layer includes other luminous material having a narrow FWHM, the organic light emitting diode can enhance its color purity.
