A touch display device includes a first substrate and a second substrate. The first substrate has a signal wire and a display unit which are electrically connected to each other. The second substrate has a conductive circuit and a touch unit which are disposed on one side of the second substrate facing the first substrate. The second substrate includes a touch area and a bending area, the touch unit is disposed in the touch area, and the touch area is stacked on the display unit, and the conductive circuit is disposed in the bending area and is electrically connected to the signal wire. The bending area extends from an edge of the first substrate and is bent to one side of the first substrate facing away from the second substrate.
