Abstract: Provided is a compound of Chemical Formula 1:




wherein: each X is independently N or CH, with two or more of the X being N; Y is O or S; and the other substituents are as described in the specification, where at least one of Ar1, Ar2 and R1 is substituted with at least one deuterium, or at least one of R2 is deuterium; and an organic light-emitting device including the same. When the compound is used as an organic light-emitting layer material, it exhibits excellent characteristics in terms of efficiency and lifetime. This is considered to be because the core dibenzofuran or dibenzothiophene group is substituted with the triazine and carbazole groups, and when at least one of Ar1, Ar2 and R1 is substituted with at least one deuterium, or at least one of R2 is deuterium, the compound exhibits increased electronic stability.
