摘要：

In order to elucidate the alignment mechanism of liquid crystal molecules on a photosensitive polymer surface, orientations of polymer molecules in the alignment layer and of liquid crystal molecules in the cell prepared using this polymer layer were measured with UV irradiation time. Our findings suggest that the liquid crystal alignment is induced through intermolecular interactions between polymer and liquid crystal molecules.
