Aim of doctoral thesis is to develop liquid crystal display technology for applications of bistable smart glass and fast switching cholesteric shutters. Various dielectric breakdown reducing methods have been studied such as roughness reduction, smoothing layer, electrode patterning and use of dielectric thin film. Screen printing, flexographic printing and magnetron sputtering were used as a deposition method. Studies of various dielectric thin films impact on bistable and cholesteric liquid crystal dielectric strength, optical transmittance and switching speed were performed. In this work dielectric breakdown mechanism in liquid crystal displays is described. Liquid crystal display with sputtered silicon dioxide have good resistance to dielectric breakdown, high transmittance and fast switching speed. All samples are made with industrial liquid crystal display manufacturing tools and correspond to technology reediness level 6.
