Abstract

A touch window includes a substrate; a sensing electrode disposed on the substrate in a bending direction of the substrate; and a wire for electrically connecting the sensing electrode. The sensing electrode includes a first sensing electrode extending in one direction on an effective area; and a second sensing electrode extending in a direction different from the extension direction of the first sensing electrode. The wire includes a first wire connected to the first sensing electrode; and a second wire connected to the second sensing electrode.
