<p>PURPOSE:To obtain an oriented film which is superior in stability at a high temperature and in life, by applying the mixture of an alkyl alkoxysilane having a long chain alkyl group and a methyl hydrogen polysiloxane onto a film and heating it to perform the orientation treatment in respect to the oriented film where liquid crystal molecules are oriented vertically. CONSTITUTION:A transparent conductive film 2 is provided on a glass substrate 1, and an orientation control film 3 is formed on this film 2, and a liquid crystal layer 4 where liquid crystal molecules are preliminarily oriented vertically is held between these substrates 1, thus obtaining a liquid crystal display element. A toluene mixed liquid of a long-chain alkyl alkoxy silane and a methyl hydrogen polysiloxane is applied to orientation control films 3 brought into contact with the liquid crystal layer 4 to perform the orientation treatment. Heat-treated films 5 are provided by heating at 150-200 deg.C. By these films 6, various liquid crystals are oriented very well in comparison with the use of conventional Na<+> ion barrier layers 6 used on the surface of an SiO2 film.</p> |
