Abstract: An input sensing device includes a first base layer, a plurality of first sensing electrodes, a plurality of second sensing electrodes, a plurality of third sensing electrodes, and a plurality of fourth sensing electrodes. The first sensing electrodes are arranged on the first base layer along a first direction. The second sensing electrodes are arranged on the first base layer in different rows from the first sensing electrodes. The third sensing electrodes are arranged on the second sensing electrodes along a second direction different from the first direction. The third sensing electrodes overlap the second sensing electrodes. The fourth sensing electrodes are arranged on the same layer as the third sensing electrodes and overlap the first sensing electrodes. A constant voltage is applied to the third sensing electrodes during a touch pressure sensing operation.
