Abstract
Provided are an organic electroluminescence device having high luminous efficiency and a long emission lifetime, and a transition metal complex compound realizing the organic electroluminescence device. In the transition metal complex compound, three ligands are crosslinked with a crosslinking group having a saturated cyclic structure or a saturated polycyclic structure in a tripod manner. The organic electroluminescence device includes an organic thin film layer composed of one or multiple layers including at least a light emitting layer, the organic thin film layer being interposed between a pair of electrodes. In the organic electroluminescence device, at least one layer of the organic thin film layer contains the transition metal complex compound.
