Abstract

Accurate optical method for measuring twist angle in TN LC cells is developed. Deviation of the measured values at different orientation of the cell and polarizes have been analyzed. The method allows to determine twist angle with high accuracy for cells with rubbed surfaces as well as for cells where at least one surface is grooved.
