This paper focuses on optimization of electrode shape in polymerstabilized blue phase or nanostructured liquid crystal composites to lower operating voltage and improve light efficiency. The electrode with taper angle of reverse elliptic shape decreases operating voltage by 18.9% and improves transmittance by 29.8% compared to that in conventional electrode structure. Additionally, the performance of the device such as contrast ratio and viewing angle characteristic is improved.
