Claim 0:
1. An organic light emitting display device, comprising:
a first light emitting part between an anode and a cathode and including a first light emitting layer;
a second light emitting part between the first light emitting part and the cathode and including a second light emitting layer; and
a first charge generation layer including a first P-type charge generation layer between the first and second light emitting parts,
wherein the first P-type charge generation layer comprises a compound represented by Chemical Formula 1:, wherein R1 and R4 each independently includes one among hydrogen, an unsubstituted aryl group with 6 to 12 carbon atoms, an unsubstituted heteroaryl group with 1 to 12 carbon atoms and 1 to 4 heteroatoms one among O, N, S, and Si, a substituted alkyl group with 1 to 12 carbon atoms, a substituted alkoxy group with 1 to 12 carbon atoms, a substituted ether group with 2 to 12 carbon atoms, a cyano group, a fluorine group, a trifluoromethoxy group, and a trimethylsilyl group,
wherein R2, R3, R5, and R6 each independently includes one among hydrogen, an aryl group with 6 to 12 carbon atoms unsubstituted or substituted with an alkoxy group or a trimethylsilyl group, a substituted or unsubstituted heteroaryl group with 1 to 12 carbon atoms and 1 to 4 heteroatoms one among O, N, S, and Si, a substituted or unsubstituted alkyl group with 1 to 12 carbon atoms, a substituted or unsubstituted alkoxy group with 1 to 12 carbon atoms, a substituted or unsubstituted ether group with 1 to 12 carbon atoms, a cyano group, a fluorine group, a trifluoromethyl group, a trifluoromethoxy group, and a trimethylsilyl group,
wherein at least one of R2, R3, R5, and R6 includes one among a substituted or unsubstituted alkoxy group with 1 to 12 carbon atoms, a substituted or unsubstituted ether group with 2 to 12 carbon atoms, and an aryl group with 6 to 12 carbon atoms substituted with an alkoxy group or a trimethylsilyl group,
wherein Z1 and Z2 are independently represented by the following Chemical Formula 2:, wherein A and B are independently one among a hydrogen atom, a substituted or unsubstituted aryl group with 6 to 12 carbon atoms, a substituted or unsubstituted heteroaryl group with 1 to 12 carbon atoms and 1 to 4 heteroatoms one among O, N, S, and Si, a substituted or unsubstituted alkyl group with 1 to 12 carbon atoms, a substituted or unsubstituted alkoxy group with 1 to 12 carbon atoms, a substituted or unsubstituted ether group with 2 to 12 carbon atoms, a cyano group, a fluorine group, a trifluoromethyl group, a trifluoromethoxy group, and a trimethylsilyl group, and
wherein Chemical Formula 2 attaches to the structure of Chemical Formula 1 at a carbon between A and B of Chemical Formula 2 through a double bond of Chemical Formula 1.
