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.)

Organic compounds and organic light emitting display device using the same

Disclosed herein is an organic light emitting diode device. The organic light emitting diode device includes an anode, a cathode and a light emitting layer. The light emitting layer has a structure where a blue light emitter and a red/green simultaneous light emitter are stacked. The red/green simultaneous light emitter has a structure where a red light emitter and a green light emitter are stacked. The red light emitter includes a red host compound, and in some embodiments, the red host compound includes a spirobisfluorene-based compound where an aryl amino group is substituted. The green light emitter includes a green host compound, and the green host compound includes a mixture of a first green host compound and a second green host compound. In some embodiments, the first green host compound includes a biscarbazole-based compound and the second green host compound includes an indolocarbazole-based compound.
