The present invention provides a liquid crystal alignment agent for forming a liquid crystal alignment film for light alignment, the liquid crystal alignment film thereof, and a liquid crystal display element with the same. According to the invention, the liquid crystal alignment agent comprises the components of: (A) polyamide acid with an optically reactive structure or a derivative thereof; and (B) polyamide acid which is obtained from dianhydride represented by a formula (1) and diamine as raw materials or a derivative thereof. Furthermore after the alignment film is formed, the component (A) and the component (B) are divided into two layers in the vertical direction. |
