Abstract

Alignment of liquid crystal induced by rubbing is not only interesting in physical chemistry but also important as a fundamental technology of mass production of liquid crystal devices. A detailed investigation on the influences of various rubbing parameters and temperature on the polyamide film has been carried out to study the temporal behavior of the pretilt angle. We also use the Taguchi Method of the Quality Engineering to prove the evaluated value and experimental value of the pretilt angle. The possibility of using the method as in-line control parameters of the alignment process in an actual LCD production facility is considered.
