Microrubbing technique to produce high pretilt multidomain liquid crystal alignment

A microrubbing (µ-rubbing) technique to create multidomain alignment in liquid crystal displays was discussed. It was found that a small metallic sphere under sufficient load was used to directly rub a polyimide alignment layer. A 47 µm linewidth and a 10° pretilt with respect to the substrate plane were demonstrated. The electro-optic performance and viewing angle characteristics of four domain samples were also elaborated
