摘要：
To provide an organic electroluminescent element excellent in lifetime characteristics, an organic electroluminescent element-testing device and an organic electroluminescent element-testing method each capable of easily testing quality of lifetime characteristics of an organic electroluminescent element in a short time without deterioration of the element, and an organic electroluminescent display device. An organic electroluminescent element having a structure in which one or more organic layers including at least a luminescent layer are interposed between electrodes, wherein the organic electroluminescent element has a photoluminescence intensity at 300 K stronger than a photoluminescence intensity at a temperature of less than 300 K, and preferably stronger than a photoluminescence intensity at 5 K.
