The distribution of the director of a nematic liquid crystal (NLC) in a cell with photosensitive aligning layers has been studied. It is shown that a doubly degenerate easy orientation axis is induced on the interface between the nematic and orienting surface. It was also found that the degeneracy of the easy axis orientation can be removed by NLC molecules flow during LC cell filling and an oblique liquid crystal orientation is realized.

The polyvinylcinnamate modified by the partial substitution of side chains for stearoyl fragments has beeninvestigated. An oblique liquid crystal alignment with pretilt angle values controlled by the concentration of the stearoyi groups is obtained. The double degeneracy ofan easy axis indUCed by polarized-light-irradiation technique is also verified.
