Title:
METHOD FOR PRODUCING ZERO-AZIMUTHAL ANCHORING FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/004433
Kind Code:
A1
Abstract:
Provided are: a method for producing a zero-azimuthal anchoring film on an industrial scale; and a good liquid crystal display element and a method for producing a liquid crystal display element, in each of which the aforementioned method is employed. A method for producing a zero-azimuthal anchoring film, the method including a step of applying an energy sufficient to cause a polymerization reaction of a radical-polymerizable compound while coming a liquid crystal composition containing a liquid crystal and the radical-polymerizable compound into contact with a radical generation film; and a method for producing a functional film, the method including a step of preparing a cell in which a liquid crystal composition containing a liquid crystal and a radical-polymerizable compound is arranged between a first substrate having a radical generation film and a second substrate having no radical generation film and a step of applying an energy sufficient to cause a polymerization reaction of the radical-polymerizable compound to the cell.
