| Abstract(in English) | Anchoring strength is an important parameter to fabricate LC devices. The surface order parameter is necessary for elucidating the anchoring and the liquid crystal alignment mechanism. But, there left a lot of unclear factors for align liquid crystals, because there is no suitable method to measure the surface order parameter quantitatively. The phase transition droplet method newly proposed in this report that is confirmed to measure the surface order parameter quantitatively. Moreover, an model to explain the decrease of order parameter which is increased by rubbing is proposed and the calculated result is agree well with the experimental value. We also found clarify that the alignment layer with no rubbing also has small order and it decreases by the plasma processing. |
