Abstract
A touch sensing device includes a first base layer, a plurality of first sensing electrodes disposed on the first base layer and spaced apart in a first direction, a plurality of second sensing electrodes disposed on a same layer as the first sensing electrodes and arranged in different rows from the first sensing electrodes, a plurality of third sensing electrodes on the second sensing electrodes that are spaced apart along a second direction different from the first direction and that overlap the second sensing electrodes, and a plurality of fourth sensing electrodes on the first sensing electrodes that are spaced apart along the second direction and that overlap the first sensing electrodes. At least two of the second sensing electrodes are directly connected to each other.
