ABSTRACT:
Provided are an organic electroluminescence device whose wavelength of light emission is short and which can emit blue light having a high color purity, and a metal complex compound for realizing the device. The metal complex compound is of a specific structure having a partial structure including two tridentate ligands. The organic electroluminescence device includes: a pair of electrodes; and an organic thin film layer which has one layer or a plurality of layers including at least a light emitting layer and is disposed between the pair of electrodes. In the organic electroluminescence device, at least one layer of the organic thin film layer contains the metal complex compound. The organic electroluminescence device emits light by applying a voltage between both the electrodes.
