Provided are an organic electroluminescent (EL) element having high luminescent efficiency, a small aging change in luminescent intensity even after the organic EL element is stored at a high temperature together with a long luminescent lifetime at a high temperature, and a method for producing the organic EL element. Further, a display and a lighting device including the organic EL element are also provided. The organic EL element contains an organic layer provided between at least a pair of a cathode and an anode. The organic layer is formed of at least one layer including a luminescent layer, and at least one layer forming the organic layer contains at least one of the compounds represented by the general formulae (A1) to (A5).
本发明提供了一种有机电致发光(EL)元件,其发光效率高,即使在高温下储存该有机 EL 元件,发光强度的老化变化也很小,并且在高温下的发光寿命长,还提供了一种生产该有机 EL 元件的方法。此外,还提供了包括有机 EL 元件的显示器和照明设备。有机 EL 元件包含至少一对阴极和阳极之间的有机层。该有机层由包括发光层的至少一层构成,而构成该有机层的至少一层含有通式(A1)至(A5)所代表的至少一种化合物。
