Abstract
Provided is an organic light emitting device having high emission efficiency and a long continuous driving lifetime. The organic light emitting device includes: an anode; a cathode; and an emitting layer placed between the anode and the cathode, in which: the emitting layer contains an emitting material that emits fluorescence; and in an emission wavelength region of the emitting material, an absorption peak of an absorption spectrum in a minimum excited triplet state of a material having a smallest minimum excited triplet energy out of constituent materials in the emitting layer is absent.
