Abstract: An organic light emitting diode (OLED) including at least one emitting material layer (EML) disposed between two electrodes and including plural delayed fluorescent materials having at least one carbazolyl moiety and BODIPY-based fluorescent material and an organic light emitting device including the OLED are discussed. The delayed fluorescent material and the fluorescent material can be included in 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 delayed fluorescent materials and the fluorescent material by adjusting energy levels among the delayed fluorescent materials and the fluorescent material.
