本研究探討聚亞醯胺型和聚醯胺酸型PI膜在摩擦配向過程的參數，對液晶顯示器中配向層配向效果的影響，其中參數包含摩擦次數、毛刷轉速、基板移動轉速和聚醯胺酸亞醯胺化溫度，配向效果的評價則包含摩擦強度和預傾角，當摩擦次數愈多，摩擦強度愈大；毛刷轉速愈快，摩擦強度也愈大，基板轉速轉速愈快，摩擦強度則相對降低，並利用原子力學顯微鏡觀察配向膜表面的粗糙效果。

　　　　　In this study, the parameters of the PI flim (polyamide and polymaic acid) including rubbing times, roller speed and substrate speed and imidization temperature in the rubbing process of the liquid crystal displays were investigated. The principal evaluations on the rubbing effect were rubbing strength and pretilt angle. The more the rubbing times and the faster the roller speed, the stronger the rubbing strength. On the contrary, the faster the substrate speed, the weaker the rubbing strength. AFM was also used to examine the roughness on the surface of alignment film.
