A system for displaying images is provided. The system includes a touch sensor device including a transparent substrate having a sensing region and a non-sensing region adjacent to the sensing region. A sensing electrode pattern layer is on the transparent substrate in the sensing region. An inorganic dielectric material layer is on the transparent substrate. The inorganic dielectric material layer has a first portion in the non-sensing region and a second portion in the sensing region and partially covering the sensing electrode pattern layer. A method of forming a touch sensor device is also disclosed.
