In particular, a transparent insulating coating used as a film to prevent alkali ion elution from the lower substrate of a liquid crystal cell, an insulating film that separates an electrode layer formed on a substrate from a liquid crystal layer, a liquid crystal alignment film in a TN liquid crystal display device, etc. The present invention relates to a paste for forming a transparent insulating film.

ンの微細化に対応できない欠点があつた。 Conventionally, this type of transparent insulating film is a film mainly composed of SiO 2 and has been formed by vacuum evaporation, dipping, or the like. However, the vacuum deposition method has poor productivity and tends to require large equipment. In addition, the dipping method has the disadvantage that a film is formed in unnecessary locations and cannot correspond to finer patterns.

いた。 In order to overcome these drawbacks, attempts have been made to print a paste into a desired shape onto a substrate using screen printing and bake it to form a transparent insulating film, but the formed film is brittle and porous. In many cases, the properties of the film itself were inferior to those formed by vacuum evaporation or immersion methods.

た。 The feature of the present invention is that metallic zirconium and organic ligands are used as the main components of the paste to form a transparent insulating film that is stronger and denser than the conventional transparent insulating film mainly composed of SiO2 . An organic zirconium (Zr) compound bonded through oxygen is dissolved in an organic solvent, and a cellulose-based viscosity agent is further added and mixed. In order to be able to form a transparent insulating film using the screen printing method, the zirconium compound must be stably dissolved in a high boiling point (180°C) organic solvent, and it must be completely dissolved at a temperature of 500°C or less. It must be an oxide. Examples of zirconium compounds that satisfy these conditions include Zr(C 5 H 7 O 2 ) 4 and Zr, in which metal zirconium and an organic ligand are bonded via oxygen.
Organic zirconium compounds such as (C 7 H 15 CO 2 ) 4 fall under this category. Organic zirconium compounds such as Zr(C 5 H 7 O 2 ) 4 and Zr(C 7 H 15 CO 2 ) 4 are combined with benzyl alcohol,
Ethyl cellulose, nitrocellulose is dissolved in a high boiling point organic solvent such as high boiling point alcohols such as dibropylene glycol and 2-ethylhexyl alcohol, high boiling point esters such as benzyl acetate and carbitol acetate, and high boiling point ethers such as butyl cellosolve. A paste is prepared by adding a cellulose-based viscous agent such as and kneading. Printing the paste on the substrate by screen printing,
The transparent insulating film mainly composed of ZrO 2 obtained by firing was a strong and dense film with good transparency.
叙上の説明のとおり、本発明は生産性がよく、
しかも、透明度良好、被膜強大で緻密な透明絶縁
被膜を提供できるという大きな利点がある。 As explained above, the present invention has good productivity and
Moreover, it has the great advantage of being able to provide a transparent insulating film with good transparency, strong film strength, and density.
