The beneficial effects of the utility model are：The advantages of the utility model at least have it is following some：
First, the utility model includes the first single diffusion layer and the second single diffusion layer, and the first single diffusion layer contacts with light guide plate,
And first the hardness of single diffusion layer be less than the hardness of the second single diffusion layer, due to being the first single diffusion layer close to the side of light guide plate
Using the relatively low softwood matter of hardness, it is possible to prevente effectively from making the friction of light guide plate exiting surface impaired and causing what light guide plate scrapped to ask
Topic, the opposite side away from light guide plate are unlikely to deform using the higher material of hardness, can provide preferable flatness and good
Spread anti-dazzle light effect；
2nd, the first single diffusion layer of close light guide plate of the present utility model uses the softer materials such as PP, and shielding is higher,
The visibility of light guide plate mesh point can be effectively reduced, improves product aesthetics and light guide plate yield, the second diffusion away from diffuser plate
Individual layer is using materials such as the higher PS of hardness, using the teaching of the invention it is possible to provide higher light efficiency and rigidity；
3rd, at least one of first single diffusion layer and the second single diffusion layer of the present utility model are nonferrous layer, or the two
Between be additionally provided with a printing opacity nonferrous layer, the discoloration diffuser plate of multilayer different colours can be done, the aesthetics of product is improved, have
Coloured light line, personalized designs sense are strong.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
