Abstract: A display device includes a display panel and a pressure sensor. The display panel displays a pressure sensing image which induces a user to apply a pressure in a specific situation. The pressure sensor is disposed under the display panel, and a portion of the pressure sensor overlaps with the pressure sensing image. An opening portion is defined in a part of an electrode of the pressure sensor that does not overlap with the pressure sensing image.
