Abstract

A compound of Chemical Formula 4 or 5: wherein: one of X1 and X2 is a direct bond, and the other is O, S, or CY1Y2, one of X3 and X4 is a direct bond, and the other is O, S, or CY3Y4, W1 to W4 are each independently N or CRa, and one or more of W1 to W4 are N, Y1 to Y4 are the same as or different from each other, and are each independently an alkyl group having 1 to 20 carbon atoms, and the other substituents are as defined in the specification; and an organic light emitting device comprising the same. The compound can lower the driving voltage, improve the light efficiency, and enhance service life characteristics of the device due to thermal stability of the compound.
