Abstract: A liquid crystal display apparatus comprising a pair of insulating substrates (10, 20), a large number of picture element electrodes (12) disposed in a matrix on the inner surface of one (10) of the pair of substrates, respective function element (15) electrically connected to each of the picture element electrodes (12), and a liquid crystal layer (30) disposed between the pair of substrates (10, 20), the display apparatus further comprises on one of the substrate. An insulating protective film (16) made of inorganic nitrides or inorganic oxides is provided on one of the substrates the insulating protective film (16) being formed on the picture element electrode except for areas that constitute window regions. An orientation film (17) of a polyimide resin is formed on the entire surface of the insulating protective film and window region, the orientation film (17) having been rubbing-processed, whereby the occurrence of an internal polarization phenomenon can be prevented when a polyimide resin is used for the orientation film.
