The surface structure of rubbed polyimides, which is responsible for the homogeneous alignment of liquid crystal molecules, was examined with use of polarized XANES spectroscopy. Our first experiment was conducted on the odd-even effect of BPDA-Cn (biphenyl-3,3',4,4'-tetracarboxylic dianhydride/n-al
