Abstract
A touch sensor according to an embodiment of the present invention includes a substrate layer, and sensing electrodes arranged on the substrate layer. The sensing electrodes includes a stacked structure of a transparent oxide electrode layer and a metal layer, and has an optical ratio of 5 or less. A structure of high transmittance and low reflectance can be implemented by a control of the optical ratio of the sensing electrodes.
