Abstract

The present disclosure relates to an organic compound, a light emitting diode and an organic light emitting diode display device using the same. The organic compound is represented by a following chemical formula 1. This organic compound has the advantages in the electron transmitting property and the thermal stability and forms a stable gap state with an alkali metal and an alkali earth metal. The driving voltage of the light emitting diode is reduced and the emission efficiency and the lifetime of the light emitting diode are improved by applying the organic compound to the charge generation layer and/or the electron transporting layer of the light emitting diode of the tandem structure.
