Provided are a composition for a liquid crystal alignment agent, a manufacturing method of a liquid crystal alignment film, a liquid crystal alignment film using the same, and a liquid crystal display device including the liquid crystal alignment film. More specifically, there are provided the manufacturing method of a liquid crystal alignment film capable of providing the liquid crystal alignment film in which light irradiation energy is able to be reduced, and alignment characteristic and stability are excellent and the voltage holding ratio and electrical characteristics are also excellent through a simple process including applying and drying the composition for a liquid crystal alignment agent on the substrate, directly performing light irradiation to conduct alignment treatment while a high-temperature heat treatment process is omitted, followed by curing by heat treatment, the liquid crystal alignment film, and the liquid crystal display device including the same.
本发明提供了一种液晶配向剂的组合物、一种液晶配向膜的制造方法、一种使用该组合物的液晶配向膜以及一种包括该液晶配向膜的液晶显示装置。更具体地说,本发明提供了一种液晶配向膜的制造方法,通过在基板上涂敷和干燥液晶配向剂组合物,直接进行光照射以进行配向处理,同时省略高温热处理工序,然后通过热处理固化,从而能够提供配向特性和稳定性优良、电压保持率和电气特性也优良的液晶配向膜,以及包括该液晶配向膜的液晶显示装置。
