Claim 13:
14. An organic light emitting diode, comprising:
first and second electrodes facing each other;
a first charge generation layer between the first and second electrodes and including a first N-type charge generation layer and a first P-type charge generation layer;
a first emitting stack including a first emitting material layer between the first electrode and the first N-type charge generation layer, a first hole auxiliary layer between the first electrode and the first emitting material layer, and a first electron auxiliary layer between the first emitting material layer and the first N-type charge generation layer; and
a second emitting stack including a second emitting material layer between the first P-type charge generation layer and the second electrode, a second hole auxiliary layer between the first P-type charge generation layer and the second emitting material layer, and a second electron auxiliary layer between the second emitting material layer and the second electrode,
wherein the first P-type charge generation layer comprises a first host and a first dopant including an organic compound represented by the following Formula 1:, wherein:
each of X1, X2 and X3 is independently selected from carbon (C) and nitrogen (N), provided that at least one of X1 to X3 is N, and
each of Z1, Z2 and Z3 is independently selected from a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C5 to C30 heteroaryl group, a substituted or unsubstituted C1 to C12 alkyl group, a substituted or unsubstituted C1 to C12 alkoxy group, a substituted or unsubstituted C1 to C12 ether group, halogen, cyano (CN), trimethylsilyl, Formula 2, Formula 3 and Formula 4, provided that at least one of Z1 to Z3 is represented by one of the following Formulas 2 to 4,, wherein in Formula 2,
each of X11 and X12 is independently selected from C and N, provided that at least one of X11 and X12 is N,
each of X13 to X16 is independently selected from C and N,
R1 is selected from a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C5 to C30 heteroaryl group, a substituted or unsubstituted C1 to C12 alkyl group, a substituted or unsubstituted C1 to C12 alkoxy group, cyano, halogen and trifluoromethyl, and
m1 is an integer of 0 to 4,
wherein in Formula 3,
each of X21 and X22 is independently selected from C and N, provided that at least one of X21 and X22 is N,
R2 is selected from cyano and phenyl,
R3 is selected from a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C5 to C30 heteroaryl group, a substituted or unsubstituted C1 to C12 alkyl group, a substituted or unsubstituted C1 to C12 alkoxy group, cyano, halogen and trifluoromethyl, and m2 is an integer of 0 to 3,
wherein in Formula 4,
each of X31 and X32 is independently selected from N and oxygen (O), provided that when one of X31 and X32 is N, then the other one of X31 and X32 is O,
each of X33 to X36 is independently selected from C and N,
R4 is selected from a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C5 to C30 heteroaryl group, a substituted or unsubstituted C1 to C12 alkyl group, a substituted or unsubstituted C1 to C12 alkoxy group, cyano, halogen and trifluoromethyl, and
m3 is an integer of 0 to 4.
