Abstract

We investigated effects of ultraviolet illuminance and ratio of high- to low-refractive-index monomers on the layer structure and light diffusion properties of light-diffusing films with alternating polymer layer structures. We clarified that an increasing difference in refractive index between alternating polymer layers induced an increase in the diffusion angle.
