Abstract: A display device includes a display panel configured to display an image on a front surface thereof, and a flexible circuit board connected to the display panel and configured to drive the display panel. The display device further includes a pressure sensor including a first electrode and a second electrode. The pressure sensor is configured to sense a change of capacitance of a capacitor, which is formed between the first electrode and the second electrode, in accordance with a pressure applied thereto. The flexible circuit board includes a first surface and a second surface facing the first surface. The first electrode and the second electrode are disposed on the first surface or the second surface.
