Abstract:
An organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode, the organic layer comprising an emission layer comprising the heterocyclic compound of Formula 1 as a host or as a delayed fluorescent dopant. The organic light-emitting device including the heterocyclic compound may have a low driving voltage and excellent maximum quantum efficiency:
