By stretching (tensile strain) a polymer dispersed liquid crystal (PDLC) film, the liquid crystal (LC) droplets become elliptical and a polarization separation optical element is created. These films have potential as scattering polarizers in liquid crystal displays (LCDs). We report a comprehensive study on the liquid crystal alignment in stretched 5CB/PVA polymer dispersed liquid crystal by means of solid‐state nuclear magnetic resonance (NMR) techniques. We are able to elucidate the nature of the liquid crystal polymer interaction by measuring the degree of orientational order at the droplet wall as a function of strain.
