摘要： Provided is a compound of Formula 1:




where X is O or S; Ar1 is an aryl having 6 to 20 carbon atoms substituted with at least one functional group selected from the group consisting of cyano, pyridinyl, benzimidazolyl and diphenylphosphine oxide, or a substituted or unsubstituted heteroaryl having 3 to 20 carbon atoms containing at least one N; and Ar2 is a functional group of Formula 2 below, with the proviso that Ar1 and Ar2 are different from each other,





where Ar3 is an aryl having 6 to 20 carbon atoms, and m is an integer of 0 to 2, and an organic light emitting device comprising the same.
