ABSTRACT:
An exemplary optical plate includes a first transparent layer, a second transparent layer and a light diffusion layer. The light diffusion layer is between the first and second transparent layers. The light diffusion layer, the first and second transparent layers are integrally formed. The light diffusion layer includes a transparent matrix resin and a plurality of diffusion particles dispersed in the transparent matrix resin. Both the first and second transparent layers define a plurality of spherical protrusions on an outer surface thereof distalmost from the light diffusion layer respectively. A method for making the optical plate is also provided. In addition, a direct type backlight module using the optical plate is also provided.
