Liquid crystal displays are commonly used recently, but productivity is not so satisfactorily high due to the occurrence of the uneven areas of brightness. Based on our empirical study, these uneven areas are believed to be caused by one of the most important processes, called rubbing process for liquid crystal display production. It was shown that fluctuation of frictional energy is the main reason for the occurrence of uneven display of brightness and elucidated the correlation between fluctuation of frictional energy and uneven display of brightness. In this research it was shown that fluctuation of frictional energy causes fluctuation of pretilt angle of liquid crystal molecule on the polyimide surface, and this fluctuation of pretilt angle on the surface causes fluctuation of brightness in liquid crystal display.
