Abstract:

An embodiment of the present invention provides an organic compound represented by following Formula: ##STR00001## wherein each of X.sub.1 to X.sub.5 is independently selected from a carbon atom (C) or a nitrogen atom (N), and at least two or three of X.sub.1 to X.sub.5 are N, wherein each of R.sub.1 and R.sub.2 is independently selected from a substituted or non-substituted aryl group or a substituted or non-substituted heteroaryl group, and "a" is an integer between zero (0) to 3, and wherein each of L.sub.1 and L.sub.2 is independently selected from a substituted or non-substituted arylene group or a substituted or non-substituted heteroarylene group, and "b" is zero (0) or 1. The present invention also provides an organic light emitting diode and an organic light emitting display device including the organic compound. The organic compound of the present invention is capable of reducing a driving voltage of an organic light emitting diode and improves a current efficiency and a lifetime of the organic light emitting diode and the organic light emitting display device including the same.
