PROBLEM TO BE SOLVED: To provide an electroluminescence element, having a long life, driven with a low voltage, by improving an injection barrier of holes and electrons from a hole injection layer to an electron injection layer.SOLUTION: The electroluminescence element includes a plurality of laminated organic layers containing at least one light-emitting layer between a pair of electrodes composed of a positive electrode and a negative electrode. By making a main material for carrier transportation at each organic layer to all be an anthracene derivative, a carrier injection barrier between respective organic layers may be improved and the electroluminescence element, having a long life, driven with a low voltage, may be provided. |
