An LCD device is provided to block the noise current coming in through a panel by using a noise current intercepting circuit equipped in a screw. An LCD panel(310) displays a screen. A printed circuit board(320) implements an LCD panel driving circuit and forms a screw hole. A screw is inserted into the screw hole. A chassis(330) combines the LCD panel and printed circuit board. A partial face of the chassis comes in contact with a ground area of the printed circuit board. A noise current intercepting circuit(340) filters the noise current coming in through the LCD panel. A resistor of the noise current intercepting circuit is earthed in the chassis. The resistor of the noise current intercepting circuit removes the noise current. A capacitor(344) of the noise current intercepting circuit is parallel connected to the resistor to supply the charged voltage to the printed circuit board. |
