Abstract
A phase‐sensitive measurement technique is proposed to characterise polymer wall formation in a nematic liquid crystal cell. The impact of photopolymerisable monomer concentration and curing time on the electro‐optical properties of polymer‐wall LC cells was studied. The experimental results indicate that optimum curing conditions for constructing the polymer wall in an LC cell can be easily achieved by means of the proposed method. The structure of the polymer walls was also investigated using scanning electron microscopy and a polarising optical microscope.
