In this thesis, the alignment characteristics and device operation of nematic liquid crystal as a function of the amount of remaining solvents were studied. Remaining solvents were observed to present as ionic form in liquid crystal and increase in quantity as the curing temperature get lowered from 120℃ to 60℃. The existance of ions in liquid crystal dose not affect the alignment properties such as pretilt angle and anchoring energy. But the response time and voltage holding ratio deteriorate as the amount of ions increases.
