An embodiment of the present invention provides an organic compound represented by:and an organic light emitting diode and an organic light emitting display device using the organic compound. The organic compound of the present invention includes a phenanthroline core, which has a nitrogen atom of a relatively electron rich sp2 hybrid orbital, and a phosphine oxide moiety, which has an excellent electron transporting property and an excellent thermal stability. The electron transporting property of the organic compound of the present invention is improved based on the chemical structure of the organic compound. Accordingly, when the organic compound is used for the organic light emitting diode and the organic light emitting display device, the driving voltage is reduced, and the lifetime and the emitting efficiency are improved. |
