Paragraph 0510; 0513-0514, (2018/03/24)
The present invention provides an in-plane switching-type liquid crystal display element imparted with a high-efficiency alignment control function, and having excellent burn-in properties. The present invention also provides a manufacturing method for a substrate having a liquid crystal alignment film, said method having the following steps for obtaining a liquid crystal alignment film for an in-plane switching-type liquid crystal display element imparted with an alignment control function: [I] a step in which a polymer composition, which contains (A) a light-sensitive sidechain polymer that exhibits liquid crystallinity at a prescribed temperature range and (B) an organic solvent, is coated on a substrate having a conductive film for in-plane switching, and a coating film is formed; [II] a step in which the coating film obtained in [I] is irradiated with polarized UV light; and [III] a step in which the coating film obtain in [II] is heated.

Nanostructures can be used for the fabrication of highly functional materials transporting ions and charges. We demonstrate a new design strategy for polymeric higher ion-conductors. Phase-segregated layers of alternating mobile tetra(ethylene oxide)s (TEOs) and rigid aromatic cores where the TEO moieties are grafted from aromatic layers have been shown to be efficient to transport lithium triflate. Such segregated structures at the nanometer scale (nano-segregated structures) were prepared by in-situ photopolymerization of an aligned methacrylate liquid crystalline monomer comprising a terphenyl rigid rod mesogen having a TEO terminal chain. The ion-conductive TEO moiety remains in the highly mobile state even after polymerization, which is indicated by its low glass transition temperature (-45 °C). This nanostructured film exhibits an ionic conductivity parallel to the layer of 10-3 S cm-1 at room temperature. The highest ionic conductivity is in the level of 10 -2 S cm-1 observed at 150 °C. The anisotropic ionic conductivities have been observed for the nano-segregated film.
