Provided is a liquid crystal aligning agent which exhibits excellent storage stability during refrigerated storage by using a crosslinkable compound that comprises a photoreactive group and has high solubility in liquid crystal aligning agents. This liquid crystal aligning agent is capable of improving the response speed of a liquid crystal display element which comprises a liquid crystal alignment film that is formed from this liquid crystal aligning agent.nA liquid crystal aligning agent which contains a crosslinkable compound represented by formula [1] wherein two or more polymerizable groups (Py 1 , Py 2 ) and ten or less crosslinkable groups (CL 1 , CL 2 ) are bonded to a parent nucleus that is composed of a divalent or higher-valent organic group.n(In formula [1], L-M-R represents a parent nucleus; each of L and R represents a carbon ring or heterocyclic ring having 4-12 carbon atoms; M represents a single bond or the like; each of S 1 , S 2 , S 3 and S 4 represents a single bond or the like; each of l, o, n and m represents an integer of 1 or more; n + m is 10 or less; and l + o is 10 or less.) |
