Abstract
A touch substrate and a manufacturing method thereof are provided. The touch substrate includes a base substrate including a touch area and a light shielding area surrounding the touch area. A first ground wiring and a second ground wiring which lies in a different layer from the first ground wiring are disposed in the light shielding area. The first ground wiring includes a first terminal exposed on a surface of the touch substrate. The second ground wiring includes a second terminal exposed on the surface of the touch substrate. The first terminal and the second terminal do not overlap with each other in a direction perpendicular to the base substrate.
