  High quality liquid crystal (LC) alignment is crucial for good performance of most LC devices that consist of rod-like nematic LC molecules.Among various alignment techniques,photoalignment is considered as a promising one.It can accomplish high quality LC alignment and simplifies the fabrication of multi-domain LC alignments.In our work,some new approaches towards generating complex LC alignments have been developed.The corresponding photonic applications are represented and their electro-optical properties are analyzed.
