Abstract

The present specification relates to an organic light emitting device including: an anode; a cathode disposed to face the anode; and a light emitting layer disposed between the anode and the cathode, in which the light emitting layer includes: a host including a P-type host and an N-type host, which produce an exciplex; and a phosphorescent dopant, and the host including the P-type host and the N-type host, which produce an exciplex, emits a photoluminescence light with a longer wavelength than a wavelength of each of the P-type host and the N-type host.
