The present invention is an organic electroluminescence element, which has a pair of electrodes and a perovskite film formed between the pair of electrodes. The perovskite film has a structure in which inorganic layers and organic layers containing organic molecules are alternately arranged. And the inorganic layer and the organic layer satisfy Eg(O)>Eg(I)>E S1 (O). Eg(O) represents the energy gap between HOMO and LUMO of the organic layer, Eg(I) represents the band gap between the valence band and conduction band of the inorganic layer, E S1 (O) represents the lowest excited singlet energy of the organic layer Order. |
