The study is based upon the dynamics theory with the liquid-crystals. Concernin g of the back-flow effect, the distributions of the direction and the velocity in OCB cell are calculated under strong anchoring and weak anchoring conditions, respectively . The time dependence of the relative intensity of the transmission light is g iven. The curves of the relative intensity of the transmission light are also g iven for the various pretilt angles. The numerical calculations show that the re sponse rate in OCB cell is faster than those in Homogeneous cell and HAN cell.
