Abstract

A method for manufacturing a liquid crystal device that includes forming an inorganic alignment layer by emitting an alignment film material that is made of an inorganic material in an oblique direction onto a substrate, and forming an organic alignment layer that is a monomolecular film made of an organic material chemically bonded with the inorganic alignment layer on a surface of the inorganic alignment layer by treating the surface of the inorganic alignment layer with a silane coupling agent that has an alkyl group, wherein a pretilt angle of a liquid crystal molecule is set to a desired angle by selecting the silane coupling agent by the number of carbon atoms.
