Recently, the existence of the unique switching mode so-called quasi-tristable switching in the surface stabilized ferroelectric liquid crystals(SSFLC) has been reported. In these papers, oblique smectic layer structure with the high surface pretilt angle were considered, and further, alternate molecular orientational model similar to the antiferroelectric arrangement were supporsed. In this study, we calculated the dynamic response of SSFLC on a basis of continuum theory, and studied the influence of the surface polar anchoring strength on the dynamic response. From this numerical calculations, the possibility of quasi-tristable switching was discussed. When the polar-anchoring strength is adequate to originate the twist orientation in the chevron structure, uniform-twist-uniform switching may be realized by applying the triangular voltage.
