An organic light-emitting element includes a first electrode, a second electrode, and at least one organic compound layer disposed between the first electrode and the second electrode. The organic compound layer includes a light-emitting layer containing a light-emitting material and being configured to emit light toward the first electrode and the second electrode. The light emitted toward the first electrode is reflected from a reflection plane located at the first electrode to cause interference with the light emitted toward the second electrode. The interference provides an interference intensity distribution having a maximum peak at a wavelength λ1. The light-emitting material of the light-emitting layer exhibits a photoluminescence spectrum having a maximum peak at a wavelength λ2. The organic light-emitting element produces an electroluminescence spectrum having a maximum peak at a wavelength λ3. These wavelengths satisfy the relationships: λ2≠λ3 and |λ2−λ3|<|λ2−λ1|. |
