Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and detailed description, this
Utility model proposes a kind of liquid crystal display device, referring to Fig.1 shown in-Fig. 6, including liquid crystal display panel 100 and backlight module, the liquid
Crystal panel 100 is located at the light emission side of the backlight module, and the backlight module includes the backboard 200 and leaded light being cascading
Plate 400, for the light guide plate 400 close to the liquid crystal display panel 100, the light guide plate 400 includes incidence surface and light-emitting surface, the back
Optical mode group further includes light source and center, it is preferred that light source is LED light 600, and the light source is set to the incidence surface side, makes
It obtains the light that light source issues and light-emitting surface outflow is entered through by the incidence surface of light guide plate 400, the center is located at the leaded light
The edge side of plate 400, there are gap between the light guide plate 400 and the light source, center, the light guide plate 400 is led for magnetism
Tabula rasa, there are magnetic attracting active forces between the magnetism light guide plate 400 and the backboard 200.Specifically, liquid in the present embodiment
Crystal device further includes having reflector plate 300, is located between magnetic light guide plate 400 and backboard 200, when assembly, by reflector plate
300, light guide plate 400 and light diaphragm 500 are cascading on backboard 200, and 200 surrounding of backboard is provided with the folding flipped up
Side is provided with LED light 600 on 200 bottom end flanging of backboard, LED light 600 can lead to for realizing the positioning to backlight module
Cross lamp bar be fitted in it is on the flanging of 200 bottom end of backboard and parallel with flanging, meanwhile, for guarantee mould group optical property, LED light
Certain fit-up gap is kept between 600 and 400 bottom edge of light guide plate, center, the center of the left and right sides are set in the surrounding of backboard 200
