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

Abstract

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.

1 . A liquid crystal display device comprising:
 a liquid crystal display panel having liquid crystal material sandwiched between a pair of substrates;   optical components disposed behind said liquid crystal display panel;   a frame-like mold which houses said liquid crystal display panel and said optical components;   a light reflective sheet disposed behind said frame-like mold; and   a frame which houses said frame-like mold and said light reflective sheet, wherein   said frame comprises a bottom portion and a sidewall formed along a periphery of said bottom portion,   said frame is provided with a plurality of engaging through holes which are formed along said sidewall,   each of said plurality of engaging through holes extends from said bottom portion into a portion of said sidewall,   said light reflective sheet is disposed on an upper surface of said bottom portion of said frame, and is provided with a plurality of cutouts disposed correspondingly to said plurality of engaging through holes such that said light reflective sheet does not lie over said plurality of engaging through holes,   said frame-like mold is provided with a plurality of engaging protrusions protruding therefrom and disposed correspondingly to said plurality of engaging holes, and   said frame-like mold and said frame are fixed together by inserting each of said plurality of engaging protrusions of said frame-like mold into a sidewall-side portion of a corresponding one of said plurality of engaging through holes.   
     
     
         2 . The liquid crystal display device according to  claim 1 , wherein said frame is further provided with a wall-like protrusion parallel with said side wall protruding from an edge of each of said plurality of engaging through holes, said edge facing toward an inside of said frame. 
     
     
         3 . The liquid crystal display device according to  claim 1 , wherein said frame-like mold and said frame are fixed together by engaging tips of said plurality of engaging protrusions with said sidewall of said frame. 
     
     
         4 . The liquid crystal display device according to  claim 2 , wherein said frame-like mold and said frame are fixed together by engaging tips of said plurality of engaging protrusions with said sidewall of said frame.
