ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE MANUFACTURING METHOD AND ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/011471
Kind Code:
A1
Abstract:
Disclosed is method of manufacturing an organic electroluminescence display device formed so as to have multiple pixels comprising organic electroluminescence elements which include: an electrode pair consisting of a positive electrode and a negative electrode; a light-emitting layer positioned between said electrodes; and an electron injection layer positioned between the aforementioned negative electrode and light-emitting layer. The disclosed organic electroluminescence display device manufacturing method involves a step of forming a light-emitting layer by coating with a solution containing a light-emitting material the substrate on which the aforementioned positive electrode is formed, a step of forming an electron injection layer by coating the aforementioned light-emitting layer with a solution containing an ionic polymer, and a step of forming the negative electrode on the aforementioned electron injection layer.
