Claim 6:
7. The compound of claim 1, wherein L1 and L2 in Formula (1) are selected from the group consisting of Formula (B-1) to Formula (B-12):, wherein:
1) a′, c′, d′ and e′ are each an integer of 0 to 4, b′ is an integer of 0 to 6, h′ is an integer of 0 to 1, and f′ and g′ are each an integer of 0 to 3,
2) R6, R7 and R8, being the same or different from each other, are each independently selected from the group consisting of deuterium; halogen; a C6-C60 aryl group; a fluorenyl group; a C2-C60 heterocyclic group including at least one heteroatom of O, N, S, Si or P; a fused ring group of a C3-C60 aliphatic ring and a C6-C60 aromatic ring; a C1-C50 alkyl group; a C2-C20 alkenyl group; a C2-C20 alkynyl group; a C1-C30 alkoxyl group; a C5-C30 aryloxy group; and -L′-N(Ra)(Rb), wherein, L′ is selected from the group consisting of a single bond; a C6-C60 arylene group; a fluorenylene group; a fused ring group of a C3-C60 aliphatic ring and a C6-C60 aromatic ring; and a C2-C60 heterocyclic, and Ra and Rb are independently selected from the group consisting of a C6-C60 aryl group; a fluorenyl group; a fused ring group of a C3-C60 aliphatic ring and a C6-C60 aromatic ring; and a C2-C60 heterocyclic group containing at least one hetero atom of O, N, S, Si, and P,
or in the case where a′, b′, c′, d′, e′, f′ and g′ are 2 or more and d is 2, R6, R7 and R8 are each in plural being the same or different from each other, and a plurality of R6 or a plurality of R7 or a plurality of R8 may be bonded to each other to form a ring, or adjacent R6 and R7, or adjacent R7 and R8 may be bonded to each other to form an aromatic or a heteroaromatic ring,
3) Y′ is NR′, 0, S, or CR′R″, wherein R′ and R″ are independently hydrogen; a C6-C60 aryl group; a fluorenyl group; a C3-C60 heterocyclic group; or a C1-C50 alkyl group; and R′ and R″ may be bonded to each other to form a spiro ring,
4) Z4, Z5 and Z6 are each independently CR′ or N, and at least one is N.
