Document Type and Number:
Japanese Patent JP4900632
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a material for an optical alignment film, capable of giving the optical alignment film having good characteristics for a liquid crystal display device, such as high alignment stability and sufficient durability to the light and heat while keeping voltage retention, and to prepare the optical alignment film. SOLUTION: The material for the optical alignment film comprises a polymerizable monomer having at least one optical alignment group which exhibits an optical alignment function through a photo-dimerization reaction and at least two polymerizable maleimide groups in its molecule. The optical alignment film on which liquid crystal molecules can be aligned without rubbing is formed by using the material. A method for producing the film is carried out by using the material.
