Abstract

We proposed a method for measuring three viscosities γ1, η1 and η2 of p-type nematic liquid crystals using dynamic retardation properties of ECB cells and tried to apply this method to n-type nematic liquid crystals. However, we found that a twist alignment appeared at the voltage-on state in VA cells, which became a severe problem for the viscosity measurement. In this paper, we propose a solution that involves applying initial bias voltage to the VA cells from theoretical analysis.
