LIQUID CRYSTAL ALIGNMENT LAYER, ITS MANUFACTURING METHOD AND LIQUID CRYSTAL DISPLAY DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal alignment layer for vertical alignment and a method for manufacturing it, to provide the liquid crystal alignment layer for the vertical alignment capable of realizing multidomain alignment without having to rub, and to provide a liquid crystal display device utilizing it. SOLUTION: The liquid crystal alignment layer 4 is composed of a monomolecular film like thin film, formed on a surface of a TFT(thin-film transistor) substrate 1 with an electrode. A molecule constituting the thin film has a fluorinated carbon group and a photosensitive group and is bonded and fixed to the substrate surface at an end part of the molecule constituting the thin film. Also the molecules constituting the thin film are aligned in a plurality of directions in a pattern per region of the thin film, and the molecules constituting the thin film are polymerized or cross-linked with themselves via the photosensitive groups.
