Abstract

PURPOSE:To improve light diffusivity by making the side surface of a lenticular lens into a total reflection surface. CONSTITUTION:In a light-diffusing screen constituted by successively providing fine lenticular lenses, light is incident from a surface A and reflected totally by side surfaces facing valley parts 2 of the lenticular lenses 1 to exit as diffused light. To increase light diffusivity, the side surface facing the valley parts 2 of the lenses are coated with material layers 4 of a material having a less refractive index than a lens medium, and light-absorbing layers 3 are formed on them, thus forming total reflection surfaces 2b.
