    Abstract: Provided is an organic light emitting device comprising an anode; a cathode; and a light emitting layer therebetween, the light emitting layer comprising a compound of Chemical Formula 1 and a compound of Chemical Formula 2, the device having improved driving voltage, efficiency and lifetime:






    wherein: any one of R′1 to R′12 is Chemical Formula 3, and the rest are hydrogen or deuterium:










    Ar1, Ar2, Ar′1, and Ar′2 are each independently a substituted or unsubstituted C6-60 aryl or C2-60 heteroaryl containing any one or more of N, O and S; R1 is hydrogen, deuterium, or a substituted or unsubstituted C6-60 aryl or C2-60 heteroaryl containing any one or more of N, O and S; and the other substituents are as defined in the specification.
