ALIGNMENT LAYER FOR LIQUID CRYSTALS |
摘要 |
An alignment layer for liquid crystals is disclosed. The liquid crystal alignment layer of the present invention is excellent in adhesion to the glass substrate, has a high liquid crystal alignment angle (pretilt angle) and generates a high pretilt angle with less dependence on the type of rubbing treatment methods and processing conditions such as heating temperature. The alignment layer for liquid crystals comprises a material selected from the group consisting of: (1) at least one polymer (A) selected from the group consisting of a polyurethane, a polyester, a polyimide, a polycarbonate and a polyurea each containing a siloxane compound as a polymer constituting component; (2) a mixture (B) of a siloxane compound and at least one polymer selected from the group consisting of a polyurethane, a polyester, a polyimide, a polycarbonate and a polyurea; or (3) a mixture of the polymer (A) and the mixture (B); and (4) a mixture of the polymer (A) and at least one polymer (D) selected from the group consisting of a polyurethane, a polyester, a polyimide, a polycarbonate, a polyurea, a polyamide and a cellulose-based compound. |
