PHOTO-ALIGNMENT MATERIAL FOR LIQUID CRYSTAL ALIGNMENT LAYER

摘要

PROBLEM TO BE SOLVED: To provide a new photo-alignment material for a liquid crystal alignment layer whose electric properties are improved by introducing a side chain structure containing no photosensitive group. SOLUTION: In the photo-alignment material containing recurring units of at least one maleimide polymer, the equivalent ratio of the recurring units containing at least one photoreactive group to the recurring units containing no photoreactive group among the recurring units containing the alignment material is 2:8 to 10:0.
