1. A touch input device comprising:
a touch sensor comprising a plurality of first electrodes, a plurality of second electrodes, and a plurality of conductive patterns;
a driving unit configured to apply a driving signal and a loop driving signal to the touch sensor; a sensing unit configured to sense a receiving signal from the touch sensor; and a control unit configured to control the driving unit and the sensing unit,
wherein a first electrode of the plurality of first electrodes comprises a plurality of first pattern parts which are arranged in a first direction and each of which has an opening therein, a first dummy pattern part disposed in the opening of a first pattern part of the plurality of first pattern parts, and a connection pattern configured to electrically connect two first pattern parts, which are adjacent to each other, of the plurality of first pattern parts,
wherein a second electrode of the plurality of second electrodes extends in a second direction perpendicular to the first direction,
wherein a conductive pattern of the plurality of conductive patterns extends in the second direction and is electrically connected to the first dummy pattern part of each of the plurality of first electrodes, and wherein two or more conductive patterns of the plurality of conductive patterns are connected to each other to constitute a current loop in which a magnetic field signal is provided to a stylus pen.
