VERTICAL ALIGNMENT MEMBRANE AND ITS MANUFACTURING METHOD, LIQUID CRYSTAL ALIGNMENT MEMBRANE, OPTICAL FILM AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a vertical alignment membrane and its manufacturing method in which a vertical alignment characteristic is provided for a liquid crystal material or the like and physical strength is satisfied.

SOLUTION: The vertical alignment membrane is obtained by coating a substrate with a mixed composition including a polymer 100 weight section having a side-chain of 12 to 28C alkyl group and a reactive diluent 200 to 2000 weight section and the composition is hardened by radioactive rays.
