Organic light emitting device

An organic light emitting device comprising:

• a first electrode;
• second electrode;
• and
• an emitting layer placed between the first electrode and the second electrode,
• wherein the emitting layer contains an emitting material that emits fluorescence and a material having a smallest minimum excited triplet energy among constituent materials of the emitting layer;
• wherein a maximum value of absorption spectrum of the material in a minimum excited triplet state exists in a region other than in an emission wavelength region of the emitting material, and
• wherein the material comprises a compound represented by the following general formula (1) or (2):
• in the general formula (1), R1 to R15 each represent a hydrogen atom or a substituted or unsubstituted alkyl group, and n represents an integer of 0 or more and 2 or less,
• in the general formula (2), R13 to R17 each represent a hydrogen atom or a substituted or unsubstituted alkyl group, R18 and R19 each represent a substituted or unsubstituted alkyl group, and n represents an integer of 0 or more and 2 or less.
