• a is an integer of 0-9,
• L′ is selected from the group consisting of a single bond, a C6-C60 arylene group, a fluorenylene group, a C2-C60 heterocyclic group comprising at least one heteroatom selected from the group consisting of O, N, S, Si and P, a C3-C60 aliphatic ring, and a fused ring of a C3-C60 aliphatic ring with a C6-C60 aromatic ring,
• Ra and Rb are each independently selected from the group consisting of a C6-C60 aryl group, a fluorenyl group, a C2-C60 heterocyclic group comprising at least one heteroatom selected from the group consisting of O, N, S, Si and P, a C3-C60 aliphatic ring and a fused ring of a C3-C60 aliphatic ring with a C6-C60 aromatic ring, and
• Ar1, Ar2, L1 to L3, L′, R1, Ra, Rb, and the ring formed by adjacent groups may be each optionally substituted with one or more substituents selected from the group consisting of deuterium, halogen, a cyano group, a C1-C20 alkyl group, a C2-C20 alkenyl group, a C6-C20 aryl group, a C6-C20 aryl group substituted with deuterium, a fluorenyl group, a C2-C20 heterocyclic group containing at least one heteroatom of O, N, S, Si, and P, and a C3-C20 aliphatic ring group,
• with the proviso that Formulas 1-A-3 to 1-A-6 meet at least one of (a) to (c):
• (a) at least one of Ar1, Ar2 and R1 is selected from:
• a C6-C18 fused aryl group;
• a substituted C6-C18 non-fused aryl group,
• a fluorenyl group substituted with one or more deuterium;
• and
• a substituted C2-C15 heterocyclic group,
• (b) at least one of L1 and L2 is selected from:
