ABSTRACT:
A method for forming a protective layer for a dielectric material in an alternating current type plasma display is provided. In this connection, a coating sol solution is provided which can form a protective layer on a large area substrate without the need to introduce any expensive equipment, the protective layer thus formed being excellent in properties such as strength, adhesion, transparency, and protective properties and capable of being formed by a sol-gel process without use of the conventional vacuum process. The sol solution comprises a dispersion of a precursor to magnesium oxide in a specific form. A method for film formation, using this solution is also provided.
