Abstract

— Novel biaxial retardation films made from photo-induced deformed cholesteric liquid-crystal (LC) nanostructures using reactive mesogen mixtures (RMMs) for a viewing-angle compensation of vertically aligned liquid-crystal displays (VA-LCDs) was developed. The deformed cholesteric LC nanostructure has been observed by X-ray-diffraction (XRD) measurement. The birefringence of the film was described well by our optical model based on a form birefringence theory. The VA-LCDs with photo-induced biaxial cholesteric films have excellent viewing-angle properties.
