The adhesion between the sealing agent and the substrate of the liquid crystal display device is excellent, again, provides a liquid crystal aligning agent to obtain the removal of the decomposition products arising after ultraviolet irradiation improved liquid crystal alignment film. Liquid crystal aligning agent containing a polymer of at least one selected from the main group is already made of a polymer imidization of the polyimide precursor and a polyimide precursor having a bond represented by the following formula (1) in the chain.
(In the formula, R
1, R
2, R
3 and R
4 are, each independently, a monovalent hydrocarbon group of 1 to 20 carbon atoms which may have a hydrogen atom or a substituent, D is a protecting group which is substituted with hydrogen atoms by heat ).
