Abstract
A touch sensor includes a first electrode, a second electrode, and a sensing channel. The first electrode includes first electrode cells arranged in a first direction, a first connection portion connecting the first electrode cells in the first direction and a first opening disposed in at least one of the first electrode cells. The second electrode includes an electrode portion disposed in the first opening. The electrode portion is disposed on a same layer as the first electrode cells and separated from the first electrode. The sensing channel includes a first terminal and a second terminal. The first terminal is connected to the first electrode. The second terminal is connected to the second electrode.
