ORGANIC EL ELEMENT, PRODUCTION METHOD FOR REFLECTIVE ELECTRODE IN ORGANIC EL ELEMENT, AND AL ALLOY SPUTTERING TARGET FOR FORMING REFLECTIVE ELECTRODE IN ORGANIC EL ELEMENT

摘要

An organic EL element including, in order, a substrate, a reflective electrode, and an organic layer laminate structure. The reflective electrode comprises an Al-type laminate film comprising, in order from the substrate side, a first thin film comprising pure Al or an Al alloy, and a second thin film comprising a nitrogen-containing Al or a nitrogen-containing Al alloy. The second thin film is directly connected to the organic layers.
