Abstract: The present disclosure relates to an organic compound having the following structure of Formula 1, an organic light emitting diode (OLED) where an electron transport layer and/or a charge generation layer includes the organic compound and an organic light emitting device including the organic light emitting diode. While only the specific moiety in the organic compound is deuterated, the organic compound can implement excellent luminous efficiency and luminous lifespan as a compound where all the carbon atoms are deuterated. The OLED can maximize its luminous efficiency and luminous lifespan with minimizing utilization of expensive deuterium.
