液晶定向剂及其所形成液晶定向膜的制造方法
摘要：
本发明是有关一种新颖的液晶定向剂及其所形成液晶定向膜与制造方法，以及具有该液晶定向膜的液晶显示元件。特别是提供一种涂布性佳的自由基聚合性液晶定向剂，及将该液晶定向剂，于基板上涂布后，进行脱水闭环及自由基聚合反应可得一信赖性佳、电压保持率佳、预倾角容易控制的液晶定向膜的制造方法，以及具有该液晶定向膜的液晶显示元件。上述自由基聚合性液晶定向剂，包含一分子中具有2个或2个以上可聚合性的马来酰胺酸基的化合物，以及有机溶剂。其液晶定向膜的制造方法乃是将上述液晶定向剂于基板上涂布后，进行脱水闭环及自由基聚合反应而得。
摘要（英）：

The invention relates to a novel liquid crystal directing agent, a liquid crystal oriented film formed by the liquid crystal directing agent, a manufacturing method of the liquid crystal oriented filmand a liquid crystal display element with the liquid crystal oriented film, in particular provides a free radical polymerized liquid crystal directing agent with good coating property, a manufacturing method of the liquid crystal oriented film which has good reliability, high voltage conservation rate and easy tilt angle control and is obtained in such a way that the liquid crystal directing agent is coated on a base plate and is performed with dehydration, ring closure and a free radical polymerization reaction, and a liquid crystal display element with the liquid crystal oriented film, wherein the free radical polymerized liquid crystal directing agent contains a molecule with two or more than two polymerizable compounds of maleamic acid radicals and an organic solvent. The manufacturing method of the liquid crystal oriented film is as follows: the liquid crystal directing agent is coated on a base plate and is performed with dehydration, ring closure and a free radical polymerization reaction.
