Abstract

By stretching (tensile strain)a polymer dispersed liquid crystal PDLC)film the liquid crystal droplets become elliptical and a polarization separation optical element is created. These films have significant potential as scattering polarizers in liquid crystal displays LCDs). We present a relationship between the polarization properties and the tensile strain properties of PDLC scattering polarizers. In addition, we present a modeling approach using a Monte‐Carlo technique to predict the alignment of liquid crystals within the droplets and the details of their surface anchoring at the cavity wall. We also extend our investigation to reactive mesogen liquid crystal and higher order liquid crystal phases, such as ferroelectric and smectic A liquid crystal materials.
