The proposed reactive monomer modified Pi-cell (RMM-Pi-cell) can suppress its critical voltage to zero, i.e. state transition free cell. The cell retardation data confirmed the initial bend orientation with zero voltage applied. The additional nematic reactive monomer (RM) layer possessed molecular average tilt angle over 80 degrees which allowed the liquid crystal molecules arranged in favored bend state in 3 mu m cell. Moreover, the light leakage of dark state was reduced. The contrast ratio of RMM-Pi-cell was improved by a factor of 11 compared with an original Pi-cell without using compensation film.
