Abstract:
One objective of the present invention is to provide an organic EL element which is suppressed in change in the resistance of a light emitting layer after passing a current therethrough for a long period of time, thereby having good emission spectrum chromaticity, and which is suppressed in change in the emission characteristics over time. Another objective of the present invention is to provide a lighting device and a display device, each of which uses the organic EL element. An organic electroluminescent element of the present invention is provided with a pair of electrodes and one or more organic layers that are arranged between the pair of electrodes, and is characterized in that one or more layers among the organic layers contain a compound that has a structure represented by general formula (1).
