A liquid crystal orientation layer contains at least one polymer selected from polyamic acids and polyimides and at least one epoxy compound having a chemical structure represented by the following formula (1) or (2), the X moieties in the formulae containing an alicyclic epoxy group or a glycidyl group represented by the following formula (a) or (b). In the foregoing formula, any one of X1 to X3 represents an alicyclic epoxy group or a glycidyl group represented by the formula (a) or (b); A represents a divalent aliphatic group; and B represents a trivalent aliphatic group. In the foregoing formula, R1 to R10, which may be the same or different, are each used for binding to A or B and besides, each represents a hydrogen atom, a halogen atom, a hydrocarbon group having from 1 to 5 carbon atoms, which may contain an oxygen atom or a halogen atom, or an optionally substituted alkoxy group having from 1 to 5 carbon atoms. In the foregoing formula, R1 to R12, which may be the same or different, are each used for binding to A or B and besides, each represents a hydrogen atom, a halogen atom, a hydrocarbon group having from 1 to 5 carbon atoms, which may contain an oxygen atom or a halogen atom, or an optionally substituted alkoxy group having from 1 to 5 carbon atoms.
