A touch display device includes a substrate. The substrate includes a display area, a non-display area, a first touch area, and a non-touch area. A first touch grid is disposed within the first touch area. A second touch grid is electrically isolated from the first touch grid and disposed within the first touch area. A first wire is disposed within the non-touch area and electrically connected to the first touch grid. A second wire is disposed within the non-touch area and electrically connected to the second touch grid. The first wire and the second wire are staggered and are electrically isolated from each other. The second wire includes at least two separate conductive units and at least one bridge wire connected to the at least two separate conductive units. An insulating layer is disposed between the first wire and the second wire.
