Abstract

This work reports the measurement of the effective order parameter of liquid crystals on the dual easy axes substrate. The effective order parameter of liquid crystals is determined from the polarized ultraviolet absorption of host-guest liquid crystals in a wedge cell. Experimental findings indicate that the ratio of the rubbing strengths in the two rubbing directions and the cell thickness substantially affect the effective order parameter of the liquid crystal molecules. The energetic competition between the surface anchoring in the two rubbing directions contributes to the observed results.
