    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.
