    摘要： Provided is an organic electroluminescence device in which a reduction in luminance is suppressed and a lifetime is significantly improved. The object is achieved by an organic electroluminescence device having organic compound layers including an organic emitting layer, which is interposed between at least one pair of electrodes, in which the organic emitting layer is formed of an organic compound material containing an impurity composed of a hydroxyl group-containing compound at a concentration of less than 0.15% by mass, and a method of selecting an organic compound material for the organic electroluminescence device, the method including: determining the content of the impurity; and selecting an organic compound material in which the content is less than 0.15% by mass so that the material is used for forming the organic emitting layer. Provided are a coating film-forming ink, a method of forming a thin film, and a method of producing an organic electroluminescence device.
