Problems solved by technology

[0007] In addition, since the transparent dielectric layer is required to have high transparency in addition to the above characteristics, the dielectric material used to form the transparent dielectric layer also needs to be easy to release air bubbles during firing.

[0078] Each sample in the table was prepared as follows.

[0079] First, raw materials were mixed and homogenized according to the glass composition shown in the table in mass %. Next, it was placed in a platinum crucible and melted at 1300° C. for 2 hours, and then the molten glass was molded into a thin plate shape. Then, it is pulverized with a ball mill and air-flow classified to obtain the average particle diameter D 50 Below 3.0μm, maximum particle siz...

Abstract

A dielectric material for plasma display panels which comprises a lead-free glass powder and, despite this, gives a dielectric layer less apt to yellow, excellent in transparency, and having a coefficient of thermal expansion suitable for glass substrates, and can be burned at a temperature of 600 DEG C or lower. Also provided are a method of forming a dielectric layer and a glass plate for plasma display panels which is formed by that method. The dielectric material for plasma display panels comprises a ZnO / B2O3-based glass powder, and is characterized in that the glass powder contains substantially no PbO and comprises a glass containing, in terms of mass%, 46-80% of ZnO+B2O3, 0.3-10% of TiO2, and 0.01-6% of CuO+MoO3+CeO2+MnO2+CoO.

Description

technical field [0001] The present invention relates to a dielectric material for a plasma display panel, a method for forming a dielectric layer, and a glass plate for a plasma display panel formed by the method. Background technique [0002] A plasma display is a self-luminous flat panel display, which has excellent characteristics such as lightness, thinness, and wide viewing angle, and can realize a large screen, so it is attracting attention as one of the promising display devices. [0003] The plasma display panel has a structure in which a front glass substrate and a rear glass substrate are opposed to each other at a certain distance, and their surroundings are hermetically sealed with sealing glass. Furthermore, rare gases such as Ne and Xe are filled inside the panel. [0004] Scan electrodes for plasma discharge are formed on the front glass substrate used for the above application, and a dielectric layer (transparent dielectric layer) for the front glass substra...
