ORGANIC ELECTROLUMINESCENT ELEMENT AND FORMATION METHOD OF ELECTROLUMINESCENCE ELEMENT METAL COMPLEX

摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescent element that has a high luminous intensity and a loing life of luminance and a new method of forming a metal complex that is useful as an organic electroluminescent element material in the organic electroluminescent element. SOLUTION: In the organic electroluminescent element which interposes an organic layer made of an organic compound film of a single or plural layers between the two mutually opposing electrodes, and which contains a ligand that is capable of forming a metal ion and complex in at least one layer of the organic compound layer and which also contains a metal source that emits metal ions in any place between the two electrodes, a metal complex that is newly formed by the ligand and the metal ions emitted from the metal source at the time of forming the element or after forming the element, emits light by the electric field.
