Low-voltage and high-Transmittance blue-phase liquid-crystal device with slanted electrodes

A low-voltage (̃10 Vrms) and high-Transmittance (̃90%) polymer-stabilized blue-phase liquid-crystal (BPLC) device with a slanted-electrodes structure is proposed. Unlike the vertical-fieldswitching (VFS) mode in which oblique incident light and a vertical field are employed, the proposed device utilizes normal incident light and an oblique field. The slanted electrodes generate a strong and uniform oblique electric field, which contributes in obtaining low voltage and high transmittance. Moreover, no couple films or prism sheets are needed, which helps to enhance the optical efficiency and simplify of the device structure. This device has great potential application for emerging BPLC displays and photonic devices.
