A touch sensing apparatus includes a touch sensor and a touch controller for sensing whether touch is present from a readout signal of the touch sensor as well as driving the touch sensor, wherein the touch sensor includes a plurality of scan channels including a plurality of first sensing electrodes arranged in a first direction in a sensing area, a plurality of readout channels including a plurality of second sensing electrodes arranged in a second direction that crosses the first direction in the sensing area, a ground routing line formed to surround the sensing area in a bezel area surrounding the sensing area, a dummy routing line formed between the ground routing line and an outermost readout channel among the plural readout channels in the bezel region, wherein a signal with the same phase as the outermost readout channel is supplied to the dummy routing line.
