1. A method of manufacturing a liquid crystal display device of the type comprising upper and lower substrates, transparent electrodes formed on the inner surfaces of said substrates, protective films covering said electrodes, liquid crystal orientation layers covering said protective films, and a liquid crystal, ##STR5## where R is selected from the group consisting of Cn H2n+a -- and Cn H2n+1 O--, interposed between said liquid crystal orientation layers, said method comprising the step of forming said liquid crystal orientation layers by depositing an inorganic substance comprising SiO onto said protective films at a deposition angle of 5°

  • to 10°

    with respect to said protective films and at a vapor deposition speed of 4A/sec to 10A/sec to provide an inclination angle of the molecule of the liquid crystal with respect to the protective film.
