Abstract
The surface molecular alignment in a sandwich cell showing V-shaped switchi ng has been investigated using a photocontrolling method. The results indic ate that the molecules on the rubbed surface are aligned parallel to the ru bbing direction as in an open cell with an air-liquid crystal boundary. Thi s alignment is due to strong in-plane anchoring, due to which the small twi sted state appears along the cell thickness through intralayer molecular in teraction.
