Claim:
1. A touch display device, comprising: a first substrate; a second substrate disposed opposite to the first substrate; and at least one touch signal transmission unit disposed at a periphery region of the touch display device, the at least one touch signal transmission unit comprising: a first conductive layer located above a side of the first substrate facing the second substrate; a second conductive layer located above a side of the second substrate facing the first substrate; a touch signal transmission layer located between the second conductive layer and the second substrate and electrically connected to the first conductive layer via the second conductive layer; and a spacer located between the first substrate and the second substrate, a vertical projection of the spacer onto the first substrate at least partially overlapping respective vertical projections of the first conductive layer and the second conductive layer onto the first substrate, wherein the spacer is disposed in the at least one touch signal transmission unit, and the first conductive layer is in contact with the second conductive layer without a touch occurring in a display region of the touch display device.
