Claim 20:
21. An organic light emitting device, comprising:
a substrate;
a first electrode;
a second electrode; and
an organic layer interposed between the first electrode and the second electrode, the organic layer comprising an emission layer,
the organic layer comprising a layer comprising at least one compound selected from the group consisting of compounds represented by Formula 1 and compounds represented by Formula 2:, X being one selected from the group consisting of a substituted or unsubstituted C1-C30 alkylene group, a substituted or unsubstituted C2-C30 alkenylene group, a substituted or unsubstituted C6-C30 arylene group, a substituted or unsubstituted C2-C30 heteroarylene group, and a substituted or unsubstituted C2-C30 hetero ring,
each R1, each R2, each R3, each R4 and each R5 independently being one selected from the group consisting of a hydrogen atom, a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C1-C30 alkoxy group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C6-C30 aryloxy group, a substituted or unsubstituted C2-C30 hetero ring, a substituted or unsubstituted C5-C30 polycyclic condensed ring, a hydroxy group, a cyano group, and a substituted or unsubstituted amino group, wherein two or more of R1, R2, and R3 can be optionally bound with one another to form a saturated or unsaturated carbon ring, and R4 and R5 can be optionally bound with one another to form a saturated or unsaturated carbon ring, and
each Ar, and each Ar2 independently being a substituted or unsubstituted C6-C30 aryl group or a substituted or unsubstituted C2-C30 heteroaryl group.
