ORGANIC ELECTROLUMINESCENT ELEMENT AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescent (EL) element that is driven in a wide range from low luminance to high brightness such as light source use, stably operates in a wide range of luminance, and is excellent in life characteristics. SOLUTION: The organic electroluminescent element has at least a pair of electrodes 2 and 5. The electrodes 2 and 5 comprise multiple function layers. The function layers include a layer 4 comprising organic solvent having at least one kind of polymeric material and possessing a light-emitting function, and an electronic charge injection layer 3 comprising at least one kind of inorganic substance.
