芳香族ジアミン誘導体、その調製法、及び液晶表示セル用の該誘導体含有整列膜材料
Document Type and Number:
Japanese Patent JP4215603
Kind Code:
B2
Abstract:
New aromatic diamine derivatives and the preparations thereof are disclosed. The inventive diamine derivatives can be added to conventional polymerization reactions of tetracarboxylic acids and diamines to form new polyamic acids. After high-temperature baking, the polyamic acids are cyclized to form polyimides. These polyimides can be used as alignment film materials for liquid crystal display cell and have good alignment property and stability, and are effective in promoting pre-tilt angle.
