有机电场发光元件用材料、有机电场发光元件、显示装置、以及照明装置
摘要：
本发明提供一种提高了驱动电压及电流效率的有机电场发光元件。本发明提供一种有机电场发光元件，其使用其中氮原子与其他杂原子或金属原子(X)于非芳香环内邻接的多环芳香族化合物作为有机电场发光元件用材料，藉此提高了上述特性。
摘要（英）：

Provided is an organic electroluminescent element which has improved driving voltage and improved current efficiency. An organic electroluminescent element having the above-mentioned improved characteristics is provided by using, as a material for organic electroluminescent elements, a polycyclic aromatic compound in which a nitrogen atom and another heteroatom or a metal atom (X) are adjacent to each other in a non-aromatic ring.
