US 2019/0377450 A1 · TOUCH PANEL, DISPLAY DEVICE AND MANUFACTURING METHOD OF TOUCH PANEL

Abstract

A touch panel, a display device and a manufacturing method of the touch panel are provided, including: a display area and a peripheral area including a bonding area; a first electrode layer and a second electrode layer configured to sense touch and an insulating layer provided between the first electrode layer and the second electrode layer; a first ground wire layer provided in the bonding area on the substrate, the insulating layer including an opening provided on the first ground wire layer, the opening exposing a part of the first ground wire layer; and a second ground wire layer provided on the first insulating layer and the exposed part of the first ground wire layer. The exposed part of the first ground wire layer and the second ground wire layer contact each other in the opening of the insulating layer in the bonding area.
