1. An organic light emitting diode, comprising:
a first electrode;
a second electrode facing the first electrode; and
an emitting material layer including a first compound and a second compound and positioned between the first and second electrodes,
wherein the first compound is represented by Formula 1:
wherein each of a1 to a3 is independently an integer of 0 to 4, and n is an integer of 1 to 5,
wherein each of R1 to R3 is independently selected from the group consisting of deuterium, tritium, a C1 to C20 alkyl, a C6 to C30 aryl and a C3 to C40 heteroaryl, or adjacent two of R1, adjacent two of R2 and/or adjacent two of R3 are combined to form a fused ring,
wherein the second compound is represented by Formula 2:
wherein each of b1 and b3 is independently an integer of 0 to 5, and b2 is an integer of 0 to 3,
wherein b4 is an integer of 0 to 4,
wherein at least one of b1 to b4 is a positive integer, and
wherein each of R11 to R14 is selected from the group consisting of deuterium, tritium, a C1 to C20 alkyl, a C6 to C30 aryl and a C3 to C40 heteroaryl.
