摘要：
The effects of surface characteristics of rubbed polyimide alignment layer on the product of zigzag free ferroelectric liquid crystals have been studied. Rubbing causes anisotropy in wettability on the polyimide surface. The flowing direction of the liquid crystal during cell filling is found to influence the molecular alignment in the resultant ferroelectric liquid crystal layer. Better aligned ferroelectric liquid crystal layer with fewer zigzag defects can be produced when the ferroelectric liquid crystal is allowed to flow into the cell toward the direction in which the alignment surface exhibits higher hydrophobicity.
