Aromatic heterocycle derivative for organic electroluminescence device, organic electroluminescence device using the same, lighting device and display device

摘要

PROBLEM TO BE SOLVED: To provide: an organic EL element that uses a novel aromatic heterocyclic derivative for organic EL elements and has high luminous efficiency, a long luminescence life, and little change over time even when used under high temperatures; and a display device and an illumination device that are equipped with the organic EL element.SOLUTION: The organic EL element has at least one organic layer, including a luminous layer, interposed between an anode and a cathode, where at least one of the organic layers contains an aromatic heterocyclic derivative having a structure represented by a specific structural formula.SELECTED DRAWING: Figure 1
