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 of delayed fluorescent materials with specific energy levels and an organic light emitting device including the diode is disclosed. When the plurality of 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.
