A liquid crystal aligning agent which can provide liquid crystal aligning capability through exposure to polarized radiation without rubbing and which is used to form a liquid crystal alignment film, a method of forming a liquid crystal alignment film, and a liquid crystal display element having this liquid crystal alignment film.
An alignment film is formed from a liquid crystal aligning agent containing a polymer having a polyamic acid ester structure with a conjugated enone structure in the side chain and applying radiation to it from a predetermined direction. Thereby, a liquid crystal display element having high thermal stability in the alignment of liquid crystals and excellent display characteristics can be manufactured.
一种液晶配向剂,可通过暴露于偏振辐射而无需摩擦,从而提供液晶配向能力,该液晶配向剂用于形成液晶配向膜;一种液晶配向膜的形成方法;以及一种具有该液晶配向膜的液晶显示元件。
对准膜是由液晶对准剂形成的,该液晶对准剂含有一种聚合物,该聚合物具有聚酰胺酸酯结构,其侧链具有共轭烯酮结构,然后从预定方向对其进行辐射。这样,就能制造出一种液晶排列热稳定性高、显示特性优异的液晶显示元件。
