Abstract

The present invention provides a method of making mechanical electrical light -emitting components with high efficiency and long driving life through a wet film formation method.The present invention involves a manufacturing method for the composition of the mechanical and electrical lighting elements. It is characterized by filtering the filtering process with liquids that contain mechanical electrical luminous components and solvents. This composition is after the filtering process is after the filtering processAfter more than 8 hours of process, the liquid is obtained by the process, which can be used for the wet formation film of the organic layer of the organic electrical luminous element.

Description

technical field [0001] The present invention relates to a method for producing a composition for an organic electroluminescence element, a composition for an organic electroluminescence element produced by the production method, a method for producing an organic electroluminescence element, and an organic electroluminescence element produced by the production method Components, and organic EL display devices and organic EL lighting containing the components. Background technique [0002] Since Kodak Corporation released a multilayer organic electroluminescence (electroluminescence: hereinafter sometimes abbreviated as "EL") device using a vapor deposition method, the development of organic EL displays and organic EL lighting has been flourishing and has been put into practical use. [0003] This type of laminated organic electroluminescent element is formed by laminating a plurality of organic layers (light-emitting layer, hole injection layer, hole transport film, electron ...
