The second and fourth harmonics of low frequency electric field-induced liquid crystal reorientations are analyzed theoretically and confirming results observed experimentally. These transient dynamic optical responses manifest when the phase of a homogeneous cell is nearby N or [image omitted], where N is an integer. These ripples would influence the grayscales of liquid crystal devices if the driving electric field frequency is comparable to the liquid crystal response rate.
