Abstract

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).
