PROBLEM TO BE SOLVED: To provide an organic electroluminescent(EL) element which is driven by low voltage. SOLUTION: This element has a structure, where a positive electrode 2, a luminescent layer 4, a first negative electrode 5 formed of a material having work function of 3.0 eV or smaller and a second negative electrode 6 having a work function larger than that of the first negative electrode are laminated sequentially on a substrate 1 from the luminescent layer side, and the first and second electrodes having the total thickness of 100 Å or smaller are laminated, and light is emitted to the outside via at least the electrodes. |
