We present two types of novel side‐chain photo‐polymers with cinnamoyl moieties for photo‐alignment and patterning of the alignment of liquid crystal displays (LCDs). One type is designed for photo‐thermal processing; the other comprises co‐polymer side‐chain functions combining room temperature photo‐processing with excellent image sticking. The planar aligning materials are highly UV sensitive (315nm, 150mJ/cm 2 ). They target in‐plane switched (IPS)‐LCDs with excellent AC‐image sticking, comparable to brushed polyimides. Correlations between photo‐dimerization and image sticking are discussed.
