A layer of a new bifunctional photoreactive side-chain copolymer (SCCP) is used for aligning liquid crystal (LC) molecules. The SCCP consists of a photo-crosslinking group as well as photo-isomerizing group. For producing uniform alignment of a nematic LC, a linearly polarized ultraviolet (LPUV) light is exposed to the SCCP film. The quality and the stability of the LC alignment upon the LPUV exposure are studied.
