Abstract

A liquid crystal display device includes a support main, a lamp housing, a printed circuit board (PCB), a top case and a cover bottom. The support main is a bottom portion of a liquid crystal display device module (LCM). The lamp housing is disposed at sides of the support main in a long side direction of the support main. The PCB is disposed on a back surface of the support main. The top case is a top portion of the LCM and has projection pieces from a side thereof. The cover bottom is disposed on an upper surface of the support main. The cover bottom has first extension pieces for electrical connection to the top case and second extension pieces projected to a lower surface of the support main for electrical connection to the printed circuit board, thereby making secure fastening and grounding.

Claims9

Dependent claims

A method of manufacturing a liquid crystal display device (LCD), the method comprising:

enclosing a liquid crystal panel and a backlight portion that provides light to the liquid crystal panel in an enclosure containing a top case and a cover bottom, the cover bottom including a main portion and the backlight portion containing a lamp and lamp housing;
supporting the enclosure with a support main;
connecting the support main and the enclosure using projection pieces that project from a side of the top case and first extension pieces that project from a side of the main portion of the cover bottom, and at least a portion of the first extension pieces extending upwardly and outwardly from a perimeter of the main portion of the cover bottom;
and
connecting the support main and a printed circuit board using a second extension piece extending downwardly and outwardly from a side of the main portion of the cover bottom toward the printed circuit board.
