Abstract
The present invention provides a back lighting plate, which is distributed with reflecting grains uniformly at inside, and has a bottom fluorescent reflecting coating and (or) an atomised top surface. Apply this optical conducting plate having many reflecting grains at inside to replace the conventional sticking diffusion film to get good reflection environment so that the light ray can be fully reflected and absorbed by the bottom fluorescent reflecting coating so as to meet the expected colour and evenness degree.
