Abstract: A touch sensing device includes an external interconnection region, patch electrodes, and internal interconnections. External interconnections are disposed in the external interconnection region. The patch electrodes are arranged in a first direction away from the external interconnection region. The patch electrodes include a first patch electrode and a second patch electrode. The internal interconnections have first ends connected to the patch electrodes, respectively, and second ends connected to one of the external interconnections. Each of the internal interconnections includes a detour portion, at least one of which at least partially extends away from the external interconnection region, and a main portion, which extends toward the external interconnection region. The detour portion of a first internal interconnection connected to the first patch electrode is longer than the detour portion of a second internal interconnection connected to the second patch electrode.
