摘要：
The present invention relates to a diffusion plate used in a direct-type backlight module and a method for making the same. At least one of the surfaces of the diffusion plate has a microstructure constituted by repeated undulation that can refract and diffuse the incident light beams that enter the diffusion plate. Therefore, the paths of the light beams after entering the diffusion plate are changed, which raises the luminance of the backlight module.
