| Abstract(in English) | The polybinyl alcohol (PVA) is prepared by the saponification of polyvinyl acetate (PVAC). The homogeneous or TN orienatation cells were assembled using the flow-induced alignment or rubbed substrate surfaces of different saponification degrees. The alignment properties have been investigated and the azimuthal anchoring energies have been measured. In the homogeneous orientation cell, the anchoring energy increases with increasing the saponification degree; moreover it also increases with the passage of time. On the other hand, the twist angle of the LC layer gradually decreased after injecting the LC in the TN cell with PVAC and PVAs of low saponification degree. Therefore, the anchoring energy measured in the TN cell is lower than that measured in the homogeneous cell. The effect of the LC orientation on the alignment interface are discussed |
