<title>Light scattering in PDLC films: how to build a better window</title>

Polymer-dispersed liquid crystals can be used to construct large-area architectural light shutters. Common problems in this application include off-axis haze and image bleedthrough. We describe a scheme which allows for wide viewing angles with low haze in powered films while maintaining adequate scattering at zero-fields. The scattering properties of films at low and high field states are related to the anomalous diffraction approximation for light scattering.
