Paper Abstract

Surface driven reorientation effects in a nematic liquid crystal cell caused by light-induced changes of the anchoring energy were studied. The threshold director reorientation takes place for the perpendicular directions of the reference and light-induced easy axes. The transition was found to be close to the second-order one revealing the critical increase of the director thermal fluctuations in the vicinity of the transition point. The mentioned effects were experimentally studied in cells of liquid crystal 5CB aligned by the photosensitive azo-containing polymer layer.
