The liquid crystal display device of the present invention is a liquid crystal display device where a light source ( 160 ) is disposed on the inner periphery of a liquid crystal module ( 100 ), which has a metal front frame ( 110 ) and a metal back cover ( 120 ), which constitute the housing of the liquid crystal module ( 100 ), and a conductive upper case ( 140 ) which is laid between a liquid crystal panel ( 130 ) and the light source ( 160 ) and has a frame having approximately the same shape as that of the front frame 110 , 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 ( 140 ) and the outer end portions of the back cover ( 120 ) are severally provided at positions overlapping with each other when the liquid crystal module ( 100 ) is assembled, and the joints ( 143 ) of the upper case ( 140 ) are sandwiched between the joints ( 112 ) of the front frame and the joints ( 123 ) of the back cover ( 120 ) in order to make the joints attachable to each other with the aid of screws ( 190 ) 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.
