The transmittance of polymer-dispersed liquid crystals (PDLC’s) can be easily controlled by a low-frequency electric field. However, unlike glass, even in its transparent state a PDLC is an anisotropic material, so its transmittance has a characteristic angular dependence. We introduce a mathematical model to describe the angular dependence of the light transmittance through a PDLC sample above threshold. The accuracy of the model is tested and predictions compared with experimental measurements.
