A light diffusing screen is made by exposing a photopolymerisable material to polymerising light through a mask having an array of light-transmitting apertures in an opaque background or vice versa, at least some of the light being directed obliquely onto the photopolymerisable material. The resulting photopolymerised material has asymmetric light diffusing properties. In some embodiments two beams of light directed onto the photopolymerisable material are equally and oppositely inclined to the perpendicular to the plane of the material. An analogous effect may be provided, in other embodiments, by exposing the photopolymerisable material to light converging conically on the photopolymerisable material.

Disclosed herein is an apparatus for maintaining and converting a localized polarization shift into a localized intensity variation in a liquid crystal display assembly. The assembly includes a liquid crystal display having a back side and a front side, a polarization-maintaining, light-diffusing layer adjacent to the front side of the liquid crystal display, and a front light-polarizing layer disposed adjacent to the polarization-maintaining, light-diffusing layer. A method for maintaining and converting a localized polarization shift into a localized intensity variation in a liquid crystal display assembly also is disclosed.
