Title:
MANUFACTURING METHOD OF ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
Japanese Patent JP2023130238
Kind Code:
A
Abstract:
To provide a manufacturing method of an organic electroluminescent element by a wet type film production, in which an electric conduction characteristic of a functional layer formed in a bank is not largely modulated from the electric conduction characteristic of an original material.SOLUTION: A manufacturing method of an organic electroluminescent element, comprises the steps of, in order: forming a structure patterned by a photo-lithography method by applying a photosensitive composition A onto a substrate including a patterned electrode layer; applying a functional component B onto the substrate having the structure; and obtaining a functional film by vaporizing an organic solvent of the functional component B by drying. The photosensitive composition A is a component containing at least one kind of high-performance material containing a fluorine atom, and the functional component B is a component containing at least one kind of electronic acceptability chemical compound containing a fluorine atom and at least one kind of organic solvent, in which Ra satisfies 17.0 or less.SELECTED DRAWING: Figure 1
