Abstract

The present disclosure relates to an organic compound and an organic light emitting display device using the same wherein the organic compound is represented by Chemical Formula 1 and a display device using the organic compound. The organic compound represented by Chemical Formula 1 has excellent electron transport properties and durability and is used for an electron transport layer of an organic light emitting element, thereby lowering a driving voltage and improving the luminous efficiency and lifetime. (In the above Chemical Formula 1, at least two of X, Xand Xare N, Yand Yare each independently a substituted or unsubstituted phenylene group or a single bond, at least one of Arand Aris selected from a substituted or unsubstituted triazine group, a functional group represented by Chemical Formula 2 and a functional group represented by Chemical Formula 3.)
