(Problem) The liquid crystal aligning agent which can form the liquid crystal display element of the PSA system excellent in various characteristics, such as high-speed response, the liquid crystal display element of the PSA system provided with the liquid crystal aligning film formed from this liquid crystal aligning agent, and manufacture of such a liquid crystal display element It is an object to provide a method. (Solution means) This invention contains the compound which has group represented by [A] following formula (1) as a liquid crystal aligning agent for liquid crystal aligning film formation in the liquid crystal display element of a PSA system. (In formula (1), R 1 is a group having at least two monocyclic structures; R 2 is a linking group containing a double bond, a triple bond, an ether bond, an ester bond, or an oxygen atom; a is an integer of 0 to 1) ). |
