STRUCTURE OF A LIQUID CRYSTAL DISPLAY DEVICE, PARTICULARLY CONCERNED IN PREVENTING A LIGHT GUIDE PLATE AND SHEETS FROM BEING MOVED OWING TO EXTERNAL SHOCK BY FIXING THEM TO A MOLD FRAME

摘要

PURPOSE: A structure of an LCD device is provided to form a guide boss which can fix a back light with a light guide plate and a mold frame, and to form fixing grooves corresponding to the guide boss on the light guide plate and sheets, so as to fix the light guide plate and the sheets to the mold frame, thereby preventing the plate and the sheets from moving by external shock. CONSTITUTION: Fixing grooves and projections(129) are formed in each stepped pulley on certain sides of a light guide plate(121) and various kinds of sheets(123,124). A guide boss(130) for fixing the sheets(123) is formed in a part where the projections(129) are located. A guide hole(133) corresponding to the guide boss(130) is disposed on an upper side of the sheets(123) fixed to an upper side of the light guide plate(121).
