Abstract: A touch display device includes a case, a liquid crystal display unit and a frame body. The case has a receiving space. The liquid crystal display unit is disposed in the receiving space of the case. The liquid crystal display unit has a display surface. At least one printed circuit layer is disposed on the display surface. Multiple transmitters and multiple receivers are electrically connected on the printed circuit layer. The frame body is mounted on the case to cover the printed circuit layer. The printed circuit layer is directly formed on the display surface of the liquid crystal display unit so that the cost for the circuit boards is saved. In this case, the manufacturing cost of the touch display device is lowered. Moreover, the total thickness of the touch display device is reduced and the installation is facilitated.
