GLASS PLATE FOR LIGHT GUIDE PLATE

摘要

This glass plate is a glass plate for a light guide plate, comprising a light emitting surface and a light scattering surface on the opposite side from the light emitting surface and having a refractive index distribution in the direction of the thickness of the plate between the light emitting surface and the light scattering surface, wherein the refractive index of the light scattering surface, calculated from a measured value of reflectance, is higher than the refractive index inside the glass plate, measured using the V-block method by removing the light emitting surface and the light scattering surface 100 microns each by polishing.
