Touch sensor

Abstract

Embodiments of the invention provide a touch sensor including a substrate, and an electrode on the substrate. The electrode includes a first diffusion barrier contacting the substrate, an intermediate layer formed on the first diffusion barrier, and a second diffusion barrier formed on the intermediate layer. According to an embodiment of the invention, corrosion of the intermediate layer and performance degradation caused by diffusion may be prevented by forming the intermediate layer on the first diffusion barrier contacting the substrate and forming the second diffusion barrier on the intermediate layer.
