The applicability of the previously proposed method for measuring the rotational viscosity, γ1, of nematic liquid crystals (NLCs) with negative dielectric anisotropy (Δε<0) from transient current in homeotropic NLC cells has been examined. It is found that the shapes of transient current in NLCs with Δε<0 are different from those with Δε>0 and hence the method can not directly be applied to the analysis of the transient current of NLCs with Δε<0. Computer simulation shows that the transient current of NLCs with Δε<0 is successfully reproduced by taking into account of flow effects. It is noted that the flow effects play a key role for faster electro-optic response in vertical alignment NLC displays.
