Abstract: A liquid crystal display apparatus comprising a pair of insulating substrates, a large number of picture element electrodes disposed into a matrix on the inner surface of one of the pair of substrates, a function element electrically connected to each of the picture element electrodes, and a liquid crystal layer charged between the pair of substrates, wherein the display apparatus further comprises on one of the substrate, an insulating protective film made of inorganic nitrides or inorganic oxides the insulating protective film being formed on the picture element electrode except for areas that constitute window regions, and an orientation film of a polyimide resin formed on the entire surface of the insulating protective film and window region, the orientation film has been rubbing-processed, whereby the occurrence of an internal polarization phenomenon can be prevented when a polyimide resin is used for the orientation film.
