Abstract: An electronic panel including a display panel and an input sensor which includes a base layer, a first sensing electrode, a first signal line electrically connected to the first sensing electrode, a first insulating layer overlapping the first sensing electrode, a second sensing electrode, a second signal line electrically connected to the second sensing electrode, and a second insulating layer overlapping the second sensing electrode, in which the first insulating layer includes an open edge that defines an open area, the open area exposes a portion of a first surface of the base layer and a portion of the first signal line in a plan view, and the first insulating layer has a first thickness at a first point spaced apart from the open edge and a second thickness greater than the first thickness at a second point disposed farther away from the open edge than the first point.

Abstract: A display device may include a display panel including a substrate that includes a display area and a pad area adjacent to the display area, and a first pad and a second pad on the pad area of the substrate, and a chip-on-film package over the pad area of the substrate with the first pad and the second pad in between, the chip-on-film package including an insulation layer, a first wiring on an upper surface of the insulation layer and electrically connected to the first pad, and a second wiring on a lower surface of the insulation layer and electrically connected to the second pad. A first signal having alternating voltage levels may be applied to the first wiring, and a second signal having a constant voltage level may be applied to the second wiring.
