LIGHT SCATTERING RESIN PANEL

摘要

PROBLEM TO BE SOLVED: To obtain a back surface light emission plate having high brightness and a uniform light emission characteristic by dispersing transparent single particulates having a refractive index different from the refractive index of a transparent resin into the transparent resin, thereby constituting a panel body. SOLUTION: The light scattering resin panel 1 comprises the panel body 2 and a reflection layer 3 disposed in the back part of the panel body 2. The panel body 2 consists of the transparent resin 2a and the transparent single particulates 2b dispersed in the transparent resin 2a. The transparent single particulate 2b are required to have the refractive index different from the refractive index of the transparent resin 2a, by which the good light scatterability is exhibited. The compounding ratio of the transparent single particulates 2b is 0.01 to 0.8 pt.wt. per 100 pts.wt. transparent resin 2a in the panel. The good light scattering effect is not obtainable if the ratio is smaller than 0.01 pt.wt. The light guide performance is lost and the uniform emission is not obtainable if the ratio is larger than 0.8 pt.wt.
