An organic light-emitting device includes a first electrode, a second electrode disposed opposite to the first electrode, and an organic layer disposed between the first electrode and the second electrode and including an emission layer. The emission layer includes at least one first light-emitting material represented by Formula 1 and at least one second light-emitting material represented by Formula 2: and Xto X, Ar, M, Xto X, A, B, Rto R, R, R, a, a, n, L, M in Formulae 1 and 2 are defined as in the specification.

Organic light-emitting device

A condensed cyclic compound represented by Formula 1 below and an organic light-emitting device (OLED) including the condensed cyclic compound are presented. Arand Arin Formula 1 are each independently one of a hydrogen atom, an aryl or heteroaryl group and an arylamino group, at least one of Arand Arbeing a substituted or unsubstituted 1,2,4-triazol-4-yl group; Land Lin Formula 1 are linking groups, each independently one of a cyclic or noncyclic, saturated or unsaturated hydrocarbon group and a heteroarylene group; a and b in Formula 1 are each independently one of 0 or 1; and Rto Rin Formula 1 being each independently one of a variety of inorganic and organic substituents including cyclic or noncyclic, saturated or unsaturated and aromatic, nonaromatic or heteraromatic groups. The OLED may have a low driving voltage, a high emission efficiency and long lifespan characteristics.
