Abstract
A touch sensor includes a substrate, and an electrode formed from a conductive stack structure including a first conductive oxide layer, a copper-containing metal layer and a second conductive oxide layer sequentially stacked from the substrate. The first conductive oxide layer and the second conductive oxide layer each include a copper-metal oxide. Chemical and mechanical stability of an electrode may be improved by the first and second conductive oxide layers.
