ABSTRACT:
A liquid crystal display comprises a liquid crystal module (10) having a predetermined shape and having a back side covered with a metal back case (12); a liquid crystal drive circuit board (20) electrically connected at one side of the liquid crystal module (10), extending toward the central portion from the one side by predetermined length, having an electric connector (22) disposed on one side of the circuit board (20), and mounted on the metal back case (12); and a metal cover (30) having a cutout (33) large enough to expose the electric connector (22) and covering the circuit board (20). An earth terminal (36) is provided at one edge of the cutout (33) and is brought into elastic contact with an earth contact (24a) provided on one side of the circuit board (20) when the circuit board (20) is covered with the metal cover (30). With this constitution, a stable ground line is formed in the display by a simple machining to avoid noise interference.
