The relaxation of a dual-frequency liquid crystal at the twist effect and the influence of the external electrical circuit parameters on the relaxation process in the case of a large initial inclination angle (44) of the director are studied. It is found that oscillation arising at the trailing edge of the modulator’s electro-optic response considerably increases the time of relaxation due to the action of a high-frequency electric field. The influence of the electric field on the relaxation time is stronger, the thinner the liquid crystal layer. It is experimentally shown that the duration of the interval between the removal of low-frequency voltage from and the application of high-frequency voltage to the modulator affects the relaxation time.
