Abstract
A method for manufacturing an organic light-emitting element, including: preparing a substrate; forming a light-reflective layer above the substrate, the light-reflective layer containing Al or an Al alloy; forming an alumina layer by oxidizing a part of the light-reflective layer; forming a metal layer on the alumina layer, the metal layer containing a metal having electrical conductivity regardless of whether or not the metal is oxidized; forming an electrically-conductive layer on the metal layer, the electrically-conductive layer containing a light-transmissive oxide; and forming an organic light-emitting layer and a light-transmissive electrode above the electrically-conductive layer.
