Polymers for photoalignment films, polymer solutions, photoalignment films, optical anisotropics, and liquid crystal display elements

Japanese Patent JP6358400

B2

The purpose of the present invention is to provide a photo-alignment film polymer which can form a photo-alignment film which can obtain a high VHR, a photo-alignment film formed from the photo-alignment film polymer, and an optically anisotropic body and a liquid crystal display element having the photo-alignment film. A first form of the present invention is a photo-alignment film polymer represented by general formula (X). A second form of the present invention is a photo-alignment film formed from the photo-alignment film polymer of the first form. A third form of the present invention is an optically anisotropic body having the photo-alignment film of the second form. A fourth form of the present invention is a liquid crystal display element having the photo-alignment film of the second form.
