A touch sensing device according to one aspect of the present disclosure includes a touch coordinate calculation unit configured to calculate a touch coordinate corresponding to the touch label on the basis of touch intensities of touch electrodes included in the touch label, a representative value calculation unit configured to calculate a representative value of the touch label by correcting the maximum touch intensity value of the touch label on the basis of a coordinate of a target touch electrode and the touch coordinate when the touch input corresponding to the touch coordinate is detected in the edge region of the target touch electrode among the touch electrodes, and a touch coordinate transmission unit configured to determine the touch input as a normal touch when the representative value is greater than or equal to a first threshold and transmit the touch coordinate to a host system.
