Liquid crystal display device comprising a frame having through holes at a bottom portion and a frame-like mold having protrusions which insert into the through holes
A liquid crystal display device includes a liquid crystal display panel having liquid crystal material sandwiched between a pair of substrates, optical components disposed behind the liquid crystal display panel, a frame-like mold which houses the liquid crystal display panel and the optical components, and a frame which houses the frame-like mold. The frame includes a bottom portion and a sidewall, and the bottom portion is provided with plural engaging through holes which are formed along the sidewall not to extend into the sidewall. The frame-like mold is provided with plural engaging protrusions which are disposed correspondingly to the engaging holes and protrude downward beyond a lower surface of the frame-like mold. The frame-like mold and the frame are fixed together by inserting each of the engaging protrusions into a corresponding one of the engaging through holes.
