Abstract
This invention in general relates to a transparent conductive layer comprising a silver nanowire. This invention further relates to an etching composition suitable for etching a transparent conductive layer comprising a silver nanowire to form a pattern. This invention further relates to a transparent conductive electrode manufactured by etching a transparent conductive film comprising a silver nanowire. The etching composition may comprise an oxidizing agent and a ligand. The oxidizing agent may be a first chemical compound that can react with silver metal to form a silver compound; and the ligand may be a second chemical compound that can react with the silver compound to form a water soluble coordination complex of the silver ion.
