摘要：PROBLEM TO BE SOLVED: To obtain a thin liq. crystal alignment layer capable of being uniformly and tightly fixed on a substrate, excellent in thermal stability of alignment and alignment regulating ability and having a wide visual field angle by fixing a coating film forming material on the surface of the substrate by directly bonding or bonding it through another coating film and crosslinking the material in the state oriented in the prescribed direction. SOLUTION: This liq. crystal alignment layer is a monomolecular film-shaped coating film formed on the surface of a substrate. A monomolecular film forming material is fixed on the surface of the substrate by directly bonding or bonding it through another coating film and it is crosslinked in the state oriented in the prescribed direction. Then, in this oriented film a precursory material forming the monomolecular film (chemical adsorbing material) contains a group represented by formula and Si and it is crosslinked at the carbon-carbon double bond parts of the group to form the monomolecular film-shaped coating film having orienting ability. In the formula, R<1> and R<2> are each H, a 1-3C alkyl group or a 1-3C alkoxy group.
