A second connector 42C is disposed on the first circuit substrate 11A; a third circuit substrate 1 1 C is disposed on the other side of the back surface of the display unit 丨0, and coupled to the second connector 42C, such that the third circuit The substrate nB can pass through the first circuit substrate 11A, receive image data from the external substrate 2, and further transfer the data to the display unit 1A. A mesh-shaped cylindrical conductor 21 is electrically coupled between the grounding point of the first circuit substrate 11A and the grounding point of the external substrate 2A to increase the area of the ground (Gnd) of the second circuit substrate 11 A. Therefore, the electric power on the display unit 10 accelerates the discharge speed by the increase of the ground path to achieve the function of completely discharging the display panel 10. The second circuit board 丨1B and the third circuit board 丨1 (: respectively having a second chip 4 1 B and a second chip 4 1 C for driving the display unit 1 〇 to display image data on the display unit Further, the first circuit board 11A, the second circuit board nB, and the third circuit board 11 C are flexible circuit boards for increasing the flexibility of the circuit, making the connection of the circuit more convenient, and saving the electronic device. The internal use of an anti-interference liquid crystal display device of the present invention has the following advantages:

Increasing LCD to prevent interference: the present invention utilizes an electrical conductor
