Abstract: An electronic apparatus includes a display panel having non-folding areas arranged along a first direction, and a folding area disposed between the non-folding areas and folded along an imaginary folding axis extending in a second direction crossing the first direction, a lower protective film disposed below the display panel, a detection sensor disposed below the protective film, and a lower member disposed below the detection sensor. The detection sensor includes a digitizer including first sensing coils and second sensing coils, which are insulated and spaced apart from each other, and a shielding layer disposed below the digitizer. The shielding layer overlaps the folding area and a shielding opening is defined through the shielding layer.

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.
