Abstract: An organic light emitting diode comprises an emitting material layer implementing a delayed fluorescence and another emitting material layer disposed adjacently to the emitting material layer and implementing fluorescence or phosphorescence and an organic light emitting device including the diode. As exciton generated in the plural emitting material layer drops to a ground state through the luminous materials each of which has a controlled energy level, it is possible to implement excellent luminous efficiency derived from a delayed fluorescent material and improved color purity derived from a fluorescent or phosphorescent material having narrow FWHM.
