    Abstract: A compound of Chemical Formula 1: where at least one of R1 to R3 is -L-Ar1, at least one of the remaining R1 to R3, which are not -L-Ar1, is a substituted or unsubstituted heteroaryl group, and the other and R11 are each independently hydrogen, deuterium, or a substituted or unsubstituted aryl or heteroaryl group, L is a direct bond or a substituted or unsubstituted arylene or heteroarylene group, and Ar1 is Chemical Formula A: where any one of Y1, Y2 and Y7 to Y11 is a moiety bonded to L, and the other substituents are as defined in the specification; and an organic light emitting device including the same. When the compound of Chemical Formula 1 is included in an organic material layer of an organic light emitting device, the device exhibits lower driving voltage, and improved light efficiency and service life.
