We study the bistability between a 180° twisted state and its topologically equivalent planar vertical state in pure nematics in the presence of a holding voltage. These bistable states can be distinguished optically by incorporating a pleochroic dye guest into the liquid crystal host. The holding voltage range ΔV of the bistability is found to increase with decreasing k1/k 3 and with decreasing dielectric anisotropy. With reasonable elastic constants and dielectric anisotropy parameter (ε∥ — ε ⊥)/ε⊥ = 0.05, the theoretical holding voltage range ΔV is about 7 % in the idealized case of perfect alignment and zero boundary tilt bias. With such boundary conditions, the cell would be subject to oppositely tilted and oppositely twisted domains, ...
