FUNCTIONAL FILM AND METHOD FOR PREPARATION THEREOF, AND LIQUID CRYSTAL DISPLAY ELEMENT USING THE SAME AND METHOD FOR PREPARATION THEREOF

摘要

The present invention is characterized in that an underlying layer solution containing a hydrolyzable compound represented by <MATH> (where X is at least one functional group selected from the group consisting of a halogen, an alkoxy group, and an isocyanate group and n is an integer equal to or more than 0) is brought into contact with a surface of a base material, the underlying layer solution is dried at a temperature less than 300 DEG C to form an underlying layer, a solution containing a silane-based compound is brought into contact with a surface of the underlying layer to cause chemical adsorption of the molecules of the silane-based compound to the surface of the underlying layer, and the base material is sintered at a temperature of 300 DEG C or more. This improves the water repellency, resistance, and heat resistance of a functional film composed of the silane-based compound, which is for modifying the properties of the surface of the base material. <IMAGE>
