Document Type and Number:
Japanese Patent JP7036240
Kind Code:
B2
Abstract:
To provide a method of manufacturing a liquid composition for organic electroluminescent element capable of stably exhibiting an excellent luminance life.SOLUTION: A method of manufacturing a liquid composition for organic electroluminescent element comprises: a preparing step for preparing the liquid composition for organic field-effect element which contains containing an organic electroluminescent compound and a specific compound; a relative amount value acquiring step for using a liquid chromatography device comprising an ultraviolet visible light detector to acquire, as a relative amount value, a ratio (B/A) of a peak area value B having a holding time corresponding to a peak of a chemical light-emission chromatogram of the liquid composition for evaluation to an area value A of a peak deriving from the specific compound; a determination step for determining whether or not the liquid composition is acceptable; and a sorting step for sorting compositions determined to be acceptable. In the method, a standard value is a value acquired as a relative amount value of a ratio (B'/A') of the area value B' of a peak of an ultraviolet visible chromatogram of a liquid composition for reference evaluation to an area valve A' of a peak deriving from a specific composition.SELECTED DRAWING: None
