Abstract
Disclosed are a heterocyclic compound of Chemical Formula 1 and an organic light emitting device including the same. When the heterocyclic compound is used as a material for an organic material layer (particularly, an electron transport layer or a charge generation layer) of an organic light emitting device, the performance of the organic light emitting device can be improved.
