Nematic liquid crystal director motion in vicinity of a glass plate is evaluated in relation to acoustic phase delay change of shear horizontal (SH) wave propagating in a cell structure. The evaluated director angle of a nematic liquid crystal 4-cyano-4'-pentylbiphenyl (5CB) in a cell prepared by irradiating ultraviolet (UV) light is a little higher than that in a rubbing cell under low voltage application. Time response of director motion under the SH wave propagation is very shorter than that of transmitted light measurement. The present technique is promising for evaluating director motion in the vicinity of the substrate surface.
