Paper Abstract

The effect of the light-induced surface reorientation of the LC director in a cell filled with an LC-azo dye mixture is obtained. The surface reorientation is caused by LC director reorientation in the bulk, which is initiated by a consequent tans-cis-trans isomerization of azo dye molecules accompanied by a variation of their orientation with respect to the polarization of the exciting light. It is shown that the value and the kinetics of the effect depend on the type of the aligning surface.
