Abstract

Review of our results of the steadies of the distribution of the director of a nematic liquid crystal in a cell with photosensitive aligning layers is presented. It is shown that a doubly degenerate easy orientation axis is induced on the nematic-orientant interface. It was also found that the degeneracy of the easy axis orientation could be removed by NLC molecules flow during LC cell filling and an oblique liquid crystal orientation is realized. The theoretical and experimental investigations of the reorientation of the director toward the light-induced easy axis caused by light-induced adsorption of dye molecules are presented. Threshold and nonthreshold effects are considered.
