Abstract

This paper discusses cells filled with a dual-frequency nematic liquid crystal (DNLC) in which the initial tilt angle θ<sub>p</sub> of the director was varied in the interval from 40<sup>°</sup> to 75<sup>°</sup> by varying the surface relief of the orienting layers. The experimental dependences of the time to change the phase lag by 2π at a wavelength of 0.65 µm on angle θ<sub>p</sub> for longitudinal and transverse deformation of the DNLC layer have been obtained for the first time. It is shown that transverse elastic deformation is a slower process than longitudinal elastic deformation. The ON or OFF time of the cells as a result of the process of longitudinal elastic deformation occupied 1–2 ms when a field is applied with frequency 1 kHz, and was 3–9 ms for transverse deformation by applying an electric field with frequency 30 kHz.
