A compound represented by Formula (1):

• wherein:
• R1, R2 and R3 are each the same or different, and each independently hydrogen or deuterium,
• a is an integer of 0 to 5, b is an integer of 0 to 6, c is an integer of 0 to 4,
• L1 and L2 are each independently selected from the group consisting of single bond;
• a C6-C60 arylene group;
• and a C2-C60 heterocyclic group including at least one heteroatom of O, N, S, Si or P;
• Ar1 and Ar2 are each independently selected from the group consisting of a C6-C60 aryl group;
• a fluorenyl group;
• a C2-C60 heterocyclic group including at least one heteroatom of O, N, S, Si or a C3-C60 aliphatic ring;
• and a fused ring group of a C3-C60 aliphatic ring and a C6-C60 aromatic ring;
• wherein the aryl group, arylene group, heterocyclic group, fluorenyl group, fluorenylene group, aliphatic ring group and fused ring group may be substituted with one or more substituents selected from the group consisting of deuterium;
• halogen;
• silane group;
• siloxane group;
• boron group;
• germanium group;
• cyano group;
