A diffusion plate comprising:
- a substrate;
- and
- a diffusion layer attached to at least one surface of the substrate, the diffusion layer comprising an adhesive and a plurality of calcium carbonate nanoparticles dispersed in the adhesive.
A method for making a diffusion plate comprising:
- providing a plurality of calcium carbonate nanoparticles and a dispersant, and dispersing the calcium carbonate nanoparticles in the dispersant to form a suspension;
- adding an adhesive into the suspension to cause the calcium carbonate nanoparticles and the dispersant to be dispersed in the adhesive, thereby forming a coating liquid;
- providing a substrate, and coating the coating liquid on at least one surface of the substrate;
- heating the substrate coated with the coating liquid;
- and
- solidifying the adhesive dispersed with the calcium carbonate nanoparticles to form the diffusion layer.

A backlight module comprising:
- a light guide plate;
- at least one light source located adjacent to an end of the light guide plate;
- and
- a diffusion plate arranged parallel to at least one light guide plate, the diffusion plate comprising:
- a substrate;
- and
- a diffusion layer attached to at least one surface of the substrate, the diffusion layer comprising an adhesive, and a plurality of calcium carbonate nanoparticles dispersed in the adhesive.
