Title:
MANUFACTURING METHOD OF ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2007115573
Kind Code:
A
Abstract:

To provide a manufacturing method with high production efficiency of an organic EL element of a multi-layer structure with high light-emitting efficiency by a wet process under atmospheric pressure conditions, as well as an organic EL display device using the organic EL element.
