Abstract: A display device includes a first sensing cell located in a display area; a first sensing line extending toward a non-display area from the first sensing cell; a second sensing cell most adjacent to the first sensing cell in a first direction in the display area; a second sensing line extending toward the non-display area from the second sensing cell; a multiplexer located in the non-display area, the multiplexer is connected to the first sensing line, the multiplexer is not connected to the second sensing line; a first pad connected to the multiplexer through a first multiplexer line; and a second pad connected to the second sensing line.

Abstract: 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.
