Compound backlight module capable of being inserted in liquid crystal display and manufacturing method thereof

The invention relates to a compound backlight module capable of being inserted in a liquid crystal display and a manufacturing method thereof. Chemical toughened glass serves as a base material, an optical layer is overlaid on the chemical toughened glass in a lithography photochemistry and adheres to a polarizer to form a compound surface light source optical substrate having the polarized light effect, the surface light source optical substrate serves as a lower glass substrate of a liquid crystal panel to manufacture the liquid crystal panel together with a lower polarizer, and finally the compound backlight module capable of being inserted in the liquid crystal display can be finished by enabling an external element to adhere to the liquid crystal display. The compound backlight module capable of being inserted in the liquid crystal display has the advantages of being high in brightness and ultra-thin and and having high performance in manufacture, and product design can be distinguished into a side inlet
