Abstract
Touch sensor including a first detection electrode portion formed on a substrate in a first direction, and a second detection electrode portion formed on the substrate in a second direction intersecting the first direction, wherein a plurality of fine etched patterns are formed in a boundary portion between unit transparent electrodes included in the first detection electrode portion and the second detection electrode portion, the unit transparent electrode has a shape in which a part of the boundary portion having a polygonal shape is removed by fine etched patterns, and the adjacent unit transparent electrodes are electrically connected. The transparent electrode may be visually hidden due to differences in optical properties between electrode regions wherein the transparent electrode is formed and inter-electrode regions wherein a transparent electrode is not formed, and a phenomenon wherein light transmittance of the touch sensor decreases due to the transparent electrode may also be prevented.
