利用摩擦配向的方式，使液晶有順序的排列於基板上，在使用反平行單方向摩擦配向時可達到此效果，另外，液晶注入口與兩基板單向摩擦配向角平分線呈90°摩擦配向也是可以嘗試看看的方法，上述兩摩擦配向模式可以使液晶更有秩序化的流動。目前反平行單方向摩擦配向和液晶注入口與兩基板單向摩擦配向角平分線呈90°皆有應用在液晶顯示器的配向製程中，例如:TFT-LCD面板的製造。藉偏光顯微鏡觀察反平行單方向摩擦配向cell和液晶注入口與兩基板單向摩擦配向角平分線呈90°cell的型態組織(morphology)。接著又利用晶體旋轉法測量反平行單方向摩擦配向cell和液晶注入口與兩基板單向摩擦配向角平分線呈90°cell的最佳預傾角，以及利用偏光片旋轉方法測液晶cell的360°明暗比。再藉由力矩平衡方程式求出反平行單方向摩擦配向cell和液晶注入口與兩基板單向摩擦配向角平分線呈90°單方向摩擦配向cell的表面錨鉤能，以及藉原子力顯微鏡觀察其粗糙度。總結上述所得參數，我們將研究摩擦配向之處理方向，並使注入液晶方面能達到最佳化，進而抑制或去除流動配向的發生。

Using the rubbing friction method to a sequence of type, we can make liquid crystal sequentially put in order on the glass substrate.By using anti-parallel single direction rubbing friction method ，we can reach this effectiveness, other, for vertical intersect submit 90 ° single direction rubbing friction method we also can try the method, above-mentioned two rubbing friction method can make liquid crystal order more to melt flow. Now ,anti-parallel single direction rubbing friction method and vertical intersect submit 90 ° single direction rubbing friction method have application all in the monitor of liquid crystal , such as: the production of TFT-LCD panel plate. By polarizing microscope ,we can observate anti-parallel single direction rubbing friction method and vertical intersect submit 90 ° single direction rubbing friction method to the morphology of these glass cells。By using torque balance equation,we could determine surface anchoring anergy.We reserched the rubbing direction to make liquid crystal injection better，so we could delete arbitrary flow.
