Claim 5:
6. A touch sensor comprising:
a substrate including a sensing area and a non-sensing area;
a touch electrode disposed on the sensing area of the substrate;
a pad part disposed on the non-sensing area of the substrate;
a connection electrode extending to the non-sensing area from one end of the touch electrode;
a first insulating layer disposed on the connection electrode in the sensing area and the non-sensing area, the first insulating layer including a first contact hole exposing at least a portion of the connection electrode; and
a connection line disposed entirely in the non-sensing area and disposed on the first insulating layer, the connection line electrically connecting the touch electrode and the pad part by being physically connected to the exposed portion of the connection electrode through the first contact hole in the first insulating layer, the connection line including a first connection line and a second connection line surrounding upper and side surfaces of the first connection line,
wherein the first connection line has a triple layer structure comprising stacked layers of molybdenum (Mo), aluminum (Al), and molybdenum (Mo) having thicknesses of 200 Å, 3000 Å, and 500 Å, respectively, and
the second connection line is a single layer made of molybdenum (Mo) and having a thickness of 2600 Å.
