碩士 === 國立臺北科技大學 === 光電工程系 === 106 === This study investigates the effect of the transmittance and Kerr constant of vertically-aligned ferroelectric liquid crystal cells driven by horizontal electric field. We poured ferroelectric liquid crystals (FLC-10855) into cells of which the thickness (d) was larger than the material pitch (p). A horizontal field is applied to the FLC cell by interdigital electrodes to drives the spontaneous polarization (Ps). Owing to the change of the liquid crystal direction, the sample transmittance increases and defects are generated above the electrodes. We use different electrode spaces and widths to prepare LC cells. By measuring their TV curves we use formulae to calculate ∆n and Kerr constant and discuss the effects.
