Applying an in-plane DC field and combining it with inversion-field method for poly(γ-benzyl L-glutamate), PBLG, liquid-crystal solution, the dynamics of band-texture evolution and the rotational dynamics of director were investigated. The textural image charge with time was recorded by video camera and then analyzed. The relationship between the band spacing and the time constant of subsequent relaxation to the new equilibrium position after an inversion of field was obtained quantitatively in various conditions of field strength, sample thickness and temperature.
