Abstract

Possible molecular orientation structures and their boundaries in surface stablized ferroelectric liquid crystals are described. The existence of pre-tilt on both glass surfaces is pointed out to explain the color difference between two twisted states and the origin of the lateral driving force of the boundary. Switching processes between the surface stablized states are discussed on the basis of stroboscopic micrographis taken by applying trianglular voltage waves of several frequencies.
