Abstract

The addition of a UV absorber to the resin prior to curing was examined as a means of controlling the internal polymer structure and refractive index distribution of an anisotropic light diffusing film. The bending of columnar polymer structures inside the film could be controlled by the amount of UV absorber and the UV irradiation conditions. Light diffusing films with bent polymer structures exhibited wide diffusion areas. When applied to reflective displays, the range of incident angles wherein ambient light is diffused was significantly larger.
