A touch sensing device for measuring a contact position of an object by measuring a change in capacitance caused by contact of an object is provided. The touch sensing device includes a touch screen panel on which channel electrodes functioning as a transmission antenna or a reception antenna are disposed to form a plurality of electrode patterns, a transmission circuit connected to the channel electrodes to apply an electrical signal to the touch screen panel, a reception circuit connected to the channel electrodes to sense a varying capacitance from the plurality of electrode patterns, and a controller configured to control the touch screen panel, the transmission circuit and the reception circuit.
