When using as a raw material of a liquid-crystal aligning agent, it has an effect which enlarges the pretilt angle of a liquid crystal, can mix a liquid crystal vertically even with a small use ratio, and mixes the poor solvent which improves applicability to the solution of a liquid-crystal aligning agent. It provides a new diamine that is difficult to precipitate even when. Diamine represented by following formula (1).n n n n n n n n (In formula (1), R < 1> is phenylene, R < 2> is cyclohexylene or phenylene, R < 3> is cyclohexylene. R < 4> is a C3-C12 alkyl group and C3-C12 fluoro. An alkyl group, a C3-C12 alkoxy group, or a C3-C12 fluoroalkoxy group) |
