Abstract
A touch sensor according to an embodiment of the present invention includes a substrate layer, sensing electrodes arranged on a top surface of the substrate layer, the sensing electrodes having boundaries in which a plurality of convex portions are connected, and a dummy electrode disposed between the sensing electrodes, the dummy electrode having a boundary in which a plurality of convex portions are connected. The sensing electrodes include a first sensing electrode arranged in a column direction and a second sensing electrode arranged in a row direction. A convex portion in a region where the first sensing electrode, the second sensing electrode and the dummy electrode are adjacent to each other has a radius of curvature less than that of a convex portion in other regions.
