Title:
ELECTRODE FOR ORGANIC ELECTROLUMINESCENCE ELEMENT, ORGANIC ELECTROLUMINESCENCE ELEMENT, ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE, AND METHOD FOR MANUFACTURING ELECTRODE FOR ORGANIC ELECTROLUMINESCENCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/181573
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrode for an organic EL element and a method for manufacturing the electrode for an organic EL element, said electrode being capable of restricting external reflection by reducing reflectivity in the visible light region; controlling a work function arbitrarily; and being applied to both a positive electrode and a negative electrode of the organic EL element. Said purpose is achieved by an electrode 20 for an organic EL element, the electrode 20 comprising: a conductive layer 1 having a metal or alloy as a main component; a blackened layer 2 having a reflectivity of 40% or less in the visible light region and provided on the conductive layer; and a work function adjusting layer 3 which is composed of a transparent conductive oxide having a predetermined work function and is provided on the blackened layer, wherein the reflectivity in the visible light region is 10% or less, and the sheet resistance is 1 Ω/sq or less.
