Abstract

Liquid crystal displays are commonly used recently, but productivity is not so satisfactorily high enough due to the occurrence of the uneven display of brightness. Based on our empirical study, these uneven display are believed to be caused by one of the most important processes, called rubbing process for liquid crystal display production. Since it was reported that frictional energy and rubbed area density are correlated closely with anchoring strength of liquid crystals, it was believed that fluctuation of frictional energy is the main reason for the occurrence of uneven display of brightness. In this research it was elucidated that the correlation between fluctuation of frictional energy and uneven display of brightness and proposed rubbing condition to prevent the occurrence of the uneven display of brightness.
