To determine the correlation between the molecular orientations of a rubbed polyimide film and a surface liquid crystal (LC) layer in contact with it, we have measured the infrared absorption spectra as a function of the incident angle. The molecular orientations were determined by fitting the incident angle dependence of the absorbance with a theoretical curve. From the comparison of the orientational distribution functions of the LC molecules and the polyimide chains, we have found that: (1) the LC molecules in the surface LC layer are on average oriented along the rubbing direction with the same inclination angle as the polyimide chains in the underlying polyimide film; (2) the ordering of the LC molecules along the rubbing direction is higher than that of the polyimide chains.
