    Abstract: A liquid crystal aligning agent contains (1) at least one polymer selected from the group consisting of a polyamic acid obtainable by a reaction between a tetracarboxylic acid dianhydride and a diamine compound and an imidized polymer obtainable by cyclization with dehydration of the polyamic acid; (2) at least one first solvent selected from the group consisting of N-alkyl-2-pyrrolidones, lactones, and 1,3-dialkyl-2-imidazolidinones; (3) at least one second solvent selected from the group consisting of: (a) a first compound represented by general formula (I) wherein R is an alkylene group having 2 or 3 carbon atoms; R is an alkyl group having 1 to 4 carbon atoms an acetyl group or a propionyl group; R is an alkyl group having 1 to 3 carbon atoms, an alkoxyl group having 1 to 3 carbon atoms, or a halogen atom; a is 1 or 2; and b is 0 or integers of from 1 to 5; and (b) a second compound represented by general formula (II) wherein R is an alkyl group having 1 to 4 carbon atoms; R is an alkylene group having 2 or 3 carbon atoms; R is an alkyl group having 1 to 3 carbon atoms; and c is 1 or 2.

    Abstract: A liquid crystal alignment agent capable of not only exhibiting excellent alignment characteristics but also forming a liquid crystal alignment layer film with which the time from cancellation of voltage application to afterimage erasure in a liquid crystal display is short; a polymer therefor; and a diamine compound as a monomer therefor. For example, there are provided liquid crystal alignment agents comprising a diamine compound having an alicyclic group, such as methyl lithocholate (3,5-diaminobenzoate), a polyamic acid being a product of reaction between the same and a tetracarboxylic anhydride and an imidized polymer therefrom, and a polymer thereof. Also, a liquid crystal display comprising the liquid crystal alignment layer film is provided.
