© 2019 SPST. Homogeneously aligned liquid crystal (LC) cell was fabricated using nematic LCs (NLCs) doped with a polymerizable monomer comprising of photocrosslinkable mesogenic side groups, combined with the linearly polarized UV light exposure at elevated temperature. We have clarified that the photosensitive layer forms on the substrates via the thermal polymerization, followed by generating the NLC photoalignment based on the axis-selective photocrosslinking. The LC characteristics of the photosensitive side groups of the polymerizable material play an important role in the defect-free alignment for the NLCs.
