液晶配向剤、液晶配向膜およびその形成方法ならびに液晶表示素子
Document Type and Number:
Japanese Patent JP5454772
Kind Code:
B2
Abstract:
Provided is a liquid crystal alignment agent which is capable of providing a pretilt-angle by photo-alignment-method and providing a liquid crystal alignment with excellent ageing-stability of the pretilt-angle. The said liquid crystal alignment agent comprises a radiation-sensitive polyorgano siloxane obtained from reacting specific polyorgano siloxane having epoxy group and (A) cinnamic acid derivate with (B) specific compound having photosensitizing structure selected from preferable acetophenone structure, benzophenone structure, anthraquinone structure, biphenyl structure, carbazole structure, nitro-aryl structure, fluorene structure, naphthalene structure, anthracene structure, acridine structure and indole structure.
