Electro-optic performance of a liquid-crystal (LC) system is enhanced by Ti O 2 nanoparticle dispersed in nematic liquid crystal (NLC). The 2.5 V threshold voltage of LC for device operation is lowered to 0.5 V through Ti O 2 nanoparticle mixing up to 2 wt. % . To characterize the shape and size distribution of the nanoparticles, high-resolution transmission electron microscopy is employed. Transmittance spectra for the Ti O 2 dispersed LC structure and nondispersed LC structure showed that transparency of the Ti O 2 dispersed LC is similar to that of pure liquid LC.
