The principal stages in technological chain of liquid crystal displays (LCD) production are presented for case where the measurement of optical polarization properties is required. Experimental set-up is described and result of LCD's substrates research are given. Influence of rubbing of polyimide layer on phase shift is considered. Analysis of five polyimide layers grouped with various structure and dopes is carried out. We have established that optical polarization technique allows to evaluate the degree and homogeneity of rubbing, determine the pre-inclination angle of polyimide molecular chains relatively to the surface of substrate.
