Claim:
A nitrogen-containing heterocyclic derivative that is represented by the following Formula 2 or includes two or more structures of the following Formula 2: wherein X 1 is N or CR 3 , X 2 is N or CR 4 , X 3 is N or CR 5 , X 4 is N or CR 6 , Y 1 is N or CR 7 , Y 2 is N or CR 8 , Y 3 is N or CR 9 , Y 4 is N or CR 10 , X 1 to X 4 and Y 1 to Y 4 are not simultaneously N, R 3 to R 11 are each independently -(L)p-(Y)q, in which p is an integer in the range of 0 to 10, q is an integer in the range of 1 to 10, and two or more adjacent groups of R 3 to R 11 may form a monocyclic or polycyclic ring, for at least one of R 3 to R 11 , p is integer in the range of 1 to 10, L is substituted or unsubstituted arylene group; substituted or unsubstituted alkenylene group; substituted or unsubstituted fluorenylene group; substituted or unsubstituted carbazolylene group; or substituted or unsubstituted heteroarylene group that includes one or more of N, O and S atoms, Y is hydrogen; heavy hydrogen; halogen group; nitrile group; nitro group; substituted or unsubstituted alkenyl group; substituted or unsubstituted silyl group; substituted or unsubstituted boron group; substituted or unsubstituted alkylamine group; substituted or unsubstituted aralkylamine group; substituted or unsubstituted arylamine group; substituted or unsubstituted heteroarylamine group; substituted or unsubstituted aryl group; substituted or unsubstituted fluorenyl group; substituted or unsubstituted carbazole group; or substituted or unsubstituted heteroring group that includes one or more of N, O and S atoms; in the case of when there are two or more L and Y, they are each independently the same as or different from each other, in (N)n 1 , N means a nitrogen atom, and the nitrogen atom is used instead of a carbon atom in a benzene ring, n 1 is an integer in the range of 0 to 2, k 1 is an integer in the range of 1 to 4, and in the case of when k 1 is an integer of 2 or more, R 11 may be different from each other.
