Abstract

Evaluating methods of the polar and/or azimuthal anchoring strength coefficients by means of the renormalized transmission spectroscopic ellipsometry are demonstrated. The Anchoring strength coefficients can be evaluated from the measurement of ellipsometric parameters measured by the oblique incident transmission ellipsometry, where the effect of multiplebeam interference is eliminated. The device parameters such as the pretilt angle and cell gap can be determined simultaneously even in the case of the twisted nematic liquid crystal sample cells.
