Abstract

Optically isotropic polymer/liquid crystal (OILC) composite film in which nano-sized liquid crystal droplets are embedded in a polymer matrix with minimal scattering is proposed for flexible LCDs with high contrast ratio, fast response time and wide-viewing-angle. Feeble light scattering in conventional OILC is overcome utilizing cholesteric LC but limiting its pitch larger than LC droplets, giving rise to higher contrast ratio. In this paper, we reports on electro-optic studies of OILC cells having various pitch sizes, exhibiting an outstanding dark state and improved transmittance.
