The surface-induced ordering of liquid crystalline (LC) molecules at the (poly imide/cyanobiphenyl LC) interface was investigated by optical anisotropy measurements in a temperature range above bulk the nematic-isotropi transition temperature, T_<NI>. The optical retardation, R of LC at the boundary region contacting with a rubbed polyimide film surface decreased with two steps with an increase of measuring temperature above T_<NI>. The plateau region of R was observed over the temperature range of 7 K. It was indicated that the temperature range of the plateau region and the magnitude of R at the plateau for the ordered thin layer might correspond to the anchoring strength which is an important parameter for controling the bulk molecular alignment based on the interfacial interation.
