A liquid crystal display comprises a liquid crystal module () having a predetermined shape and having a back side covered with a metal back case (); a liquid crystal drive circuit board () electrically connected at one side of the liquid crystal module (), extending toward the central portion from the one side by predetermined length, having an electric connector () disposed on one side of the circuit board (), and mounted on the metal back case (); and a metal cover () having a cutout () large enough to expose the electric connector () and covering the circuit board (). An earth terminal () is provided at one edge of the cutout () and is brought into elastic contact with an earth contact () provided on one side of the circuit board () when the circuit board () is covered with the metal cover (). With this constitution, a stable ground line is formed in the display by a simple machining to avoid noise interference.

The liquid crystal display device of the present invention is a liquid crystal display device where a light source () is disposed on the inner periphery of a liquid crystal module (), which has a metal front frame () and a metal back cover (), which constitute the housing of the liquid crystal module (), and a conductive upper case () which is laid between a liquid crystal panel () and the light source () and has a frame having approximately the same shape as that of the front frame, in which perforated joints, which are bent vertically and integrally formed on the outer end portions of the front frame, the outer end portions of the upper case () and the outer end portions of the back cover () are severally provided at positions overlapping with each other when the liquid crystal module () is assembled, and the joints () of the upper case () are sandwiched between the joints () of the front frame and the joints () of the back cover () in order to make the joints attachable to each other with the aid of screws () with a foot length less than the width of the front frame. A liquid crystal display device is thereby obtained according to the present invention, in which highly reliable ground connection is realized even when used in an environment subject to frequent vibration.
