The present invention provides a novel light-emitting device being capable of application in various areas and having excellent characters and efficiency of light-emitting. The invention relates to a light-emitting device containing at least one platinum complex represented by the following general formula (1): (wherein, ring A, ring B, ring C, every two independently, represent optionally substituted nitrogen-containing aromatic heterocyclic groups by coordination of nitrogen atom and platinum atom, and the remaining ring represents optionally substituted aryl group or optionally substituted heteroaryl group; Y represents halogen atom, or a direct bond or bonding via oxygen atom (-O-) or sulfur atom (-S-) to an optionally substituted aryl group or optionally substituted heteroaryl group (exception: adjacent two rings are nitrogen-containing aromatic heterocyclic group, Y is not a chlorine atom; non-adjacent two rings are nitrogen-containing aromatic heterocyclic group, Y is halogen atom). |
