Abstract
The total reflection ellipsometry (TRE) method is proposed to investig ate the behavior of the liquid crystal (LC) molecules at the interface between LC and an alignment film. Theoretical analysis indicated that the TRE method is useful for studying: the behavior of interfacial LC molecules. From the numerical results of the TRE method, it was found that the phase difference versus applied voltage depends on the polar anchoring strength. The TRE method is sensitive enough to estimate th e polar anchoring strength of LC cells.
