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.
