Abstract
A liquid crystal display device of the type comprising outer and lower substrates, electrodes formed on the inner surfaces of the substrates, liquid crystal orientation layers covering the protective films, and a liquid crystal interposed between the liquid crystal orientation films, is manufactured by forming the liquid crystal orientation layers by depositing SiO onto the protective films at a definite deposition angle with respect to the protective films and at a vapor deposition speed which varies in accordance with the type of the liquid crystal used.
