According to progress of the LCD televisions, development of high-speed switching LCD is strongly demanded. In the switching process of the LCD, we clarified that the flow effect acted an important role. The fundamental theory of the flow effects are formed by the Ericksen-Leslie using five viscosity coefficients. However, there is no simple and reliable method to measure these viscosity coefficients without special equipment. In this paper, we propose a simple and accurate method to determine the rotational viscosity γ_1 and Miesowicz's viscosity, coefficients η_1 and η_2 whose parameters are most dominant in the switching process.
