Abstract
A metal-complex compound which comprises a tridentate chelate ligand having a specified partial structure. An organic electroluminescence device which comprises at least one organic thin film layer sandwiched between a pair of electrode consisting of an anode and a cathode, wherein the organic thin film layer comprises the metal-complex compound, which emits light by applying an electric voltage between the pair of electrode. The present invention provides an organic EL device which emits blue light with high purity and of short wavelength with an enhanced efficiency of light emission.
