<p>PURPOSE:To obtain a liquid crystal display element free from uneven orientation and superior in contrast by forming a vertically orienting film on a glass base provided with a transparent electrode by the method of glow discharge plasma polymn. of an org. compd. having F in the molecule. CONSTITUTION:A glass base 1 provided with a transparent electrode 2 is placed on the lower electrode 11 arranged in the inside of a bell jar 12 evacuated with a vacuum pump 16, a fluorinated aliphatic or alicyclic unsatd. compd., such as gaseous F2C=CF2, perfluorobutene-2, hexafluorobutadiene-1, or hexafluorocyclobutene, is introduced from a cylinder 17 through a tube 18, and a high-frequency electric field is applied with a high-frequency matching unit 13 to form a vertically orienting film 3 on the base 1. Nematic liquid crystals 6 having dielectric anisotropy is sealed in between this film 3 and a plasma polymn. film 3' likewise formed on an opposite base 1', and a reflective plate 5 is formed on the backside of the base 1', thus forming a display device good in visual recognizability and contrast.</p> |
