A display device may include a display element layer, a sensing element layer, and a second-type sensor electrode. The display element layer may include a first through hole, a non-pixel area, and a display area. The display area may including pixels and may surround the non-pixel area. The non-pixel area may surround the first through hole. The sensing element layer may include a second through hole and a first sensing area. The first sensing area may include first-type sensor electrodes, may overlap the display area, and may surround the second through hole. The second through hole may correspond to the first through-hole. The second-type sensor electrode may overlap the non-pixel area and may be electrically insulated from the first-type sensor electrodes.
