Claim Text:
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 the one or more organic material layers comprise a light emitting layer, an organic material layer comprising a compound represented by the following Formula 1 and an organic material layer comprising a compound represented by the following Formula 2 are comprised between the anode and the light emitting layer, the organic material layer comprising a compound represented by the Formula 2 is a hole transport layer, and the organic material layer comprising a compound represented by the Formula 1 is an 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 each independently 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, Ar3 and Ar4 are the same as or different from each other, and each independently selected from the group consisting of a substituted or unsubstituted phenyl group or a substituted or unsubstituted biphenyl group, L is a substituted or unsubstituted arylene group having 6 to 30 carbon atoms, wherein, CY3 to CY4 are the same as or different from each other, and each independently represent a benzene cycle or a naphthalene cycle, Ar5 to Ar8 are the same as or different from each other, and each independently 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, at least one of Ar7 and Ar8 is a substituted or unsubstituted fluorene group or a substituted or unsubstituted naphthyl group, and L is a substituted or unsubstituted arylene group having 6 to 30 carbon atoms.
