Abstract
Nonrubbed UV curable polymer surfaces for liquid crystal alignment are made by copying the aligning function of a stretched or rubbed polyethylenterephthalate (PET) film surface. Optical anisotropy is generated and the surface topology is found to be isotropic on an alignment surface prepared using the stretched film. Both topological and optical anisotropies are generated on the surface where the rubbed PET film surface is copied. The azimuthal anchoring energy of the latter surface is larger than that of the former surface.
