Claim:
1. An organic light emitting diode comprising an anode, a cathode, and one or more organic material layers interposed between the anode and the cathode, wherein: a first organic material layer is a light emitting layer, a second organic layer is an electron blocking layer interposed between the anode and the light emitting layer, the electron blocking layer comprising a compound represented by following Formula 1, a third organic material layer comprising a compound represented by the following Formula 2 or 3 is interposed between the cathode and the light emitting layer, and a fourth organic material layer is a hole transport layer interposed between the anode and the electron blocking layer: wherein, CY1 and CY2 are the same as or different from each other, and each independently represent a benzene cycle or a naphthalene cycle, Ar1 and Ar2 are the same as or different from each other, and are each independently selected from the group consisting of hydrogen and a phenyl group, Ar3 is selected from the group consisting of hydrogen; a substituted or unsubstituted aryl group having 6 to 30 carbon atoms; and a substituted or unsubstituted heteroaryl group having 5 to 30 carbon atoms, Ar4 is selected from the group consisting of a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, a substituted or unsubstituted triphenylene group, and a substituted or unsubstituted heteroaryl group having 5 to 30 carbon atoms, L is a substituted or unsubstituted arylene group having 12 to 30 carbon atoms, wherein, X1 to X6 are the same as or different from each other, and each independently N or CH, Ar5 to Ar11 are the same as or different from each other, and are each independently selected from the group consisting of a substituted or unsubstituted phenyl group; a substituted or unsubstituted biphenyl group; a substituted or unsubstituted naphthyl group; a substituted or unsubstituted anthracenyl group; a substituted or unsubstituted phenanthrenyl group; and a fluorenyl group, which is unsubstituted or substituted with one or more substituent groups selected from the group consisting of heavy hydrogen, a halogen group, an alkyl group, an alkenyl group, an alkoxy group, a silyl group, an arylalkenyl group, an aryl group, a heteroaryl group, a carbazole group, an arylamine group, a fluorenyl group, and a nitrile group; a substituted or unsubstituted pyrimidinyl group; a substituted or unsubstituted quinolyl group; and a substituted or unsubstituted pyrazinyl group, and L1 is a substituted or unsubstituted arylene group having 6 to 30 carbon atoms.
