We proposed a simple and accurate method for measuring the twist elastic constant K22 of liquidcrystal materials. The novel technique is based on the ellipsometry analysis, and determines the director profile of a twisted nematic liquid crystal cell in the on state. We validated this experimentally, and showed that it is effective for evaluating the response characteristics of liquid crystal displays.
