Abstract: A display device includes a display panel; a pressure sensor disposed on the display panel; and a lower bracket. The pressure sensor is disposed between the display panel and the lower bracket and is disposed on the lower bracket. The pressure sensor includes a first substrate, a first pressure sensing layer disposed between the first substrate and the lower bracket, a first driving electrode disposed between the first pressure sensing layer and the lower bracket, and a first sensing electrode spaced apart from the first driving electrode. A gap is present between the first pressure sensing layer, and the first driving electrode and the first sensing electrode.

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.
