Kind Code:
A1
Abstract:
Disclosed are: a material for a liquid crystal alignment film, which does not undergo film detachment or scratching during rubbing even when the material is burned at a temperature of 200˚C or lower and can achieve good liquid crystal alignment properties; and a novel diamine which is used in the material.
Specifically disclosed is a liquid crystal aligning agent comprising at least one polymer selected from the group consisting of a polyamic acid and a polyimide produced by dehydrating and ring-closing the polyamic acid, wherein a diamine component comprises a diamine represented by formula [3].
(In the formula, R3 represents a group selected from the group consisting of -CH2-, -O-, -CONH-, -NHCO-, -COO-, -OCO- and -NH-; R4 represents a single bond or an alkylene group having 1-10 carbon atoms; R5 represents a single bond, -CH2-, -O- or -NH-; R6 represents a bivalent organic group which is composed of one or several rings, has at last one aromatic ring at an terminal thereof, and has 5-18 carbon atoms; and R7 represents a hydrogen atom, a methyl group or the like.)
