It was confirmed that contamination in liquid crystal (LC) deteriorates the reliability
of the estimation of device parameter such as flexoelectric coefficient especially
when measuring the phase difference of LC sample
by means of the symmetric oblique incident transmission ellipsometry with applying DC voltage.
