Problems solved by technology

However, as far as ZnO-B 2 o 3 In terms of glass powder, there are restrictions on the technology that can be used in JP-A-2002-110035
For example, ZnO-B in JP-A-2002-110035 2 o 3 Glass powder containing a large amount of BaO, and for glass powder with a small BaO content, it is difficult to make a transparent partition wall even if it is combined with alumina powder

Embodiment Construction

[0017] According to investigations by the inventors of the present invention, when mullite powder is used instead of alumina powder, even when ZnO-B with a small BaO content is used, 2 o 3 In the case of glass powder, translucent partition walls can also be formed. Therefore, it is speculated that this is because this ZnO-B 2 o 3 The glass of the glass tends to have a refractive index closer to that of mullite than that of alumina.

[0018] Hereinafter, the partition wall forming material of the present invention will be described in detail.

[0019] The partition wall forming material for a plasma display panel of the present invention includes ZnO-B 2 o 3 It is glass powder and filler powder. The ratio of the two is ZnO-B 2 o 3 60-90% by mass of glass powder, 10-40% by mass of filler powder, preferably ZnO-B 2 o 3 60-85 mass % of glass powder, 15-40 mass % of filler powder, more preferably ZnO-B 2 o 3 The glass powder is 63-84% by mass, and the filler powder is 1...

Abstract

The present invention relates to a partition wall forming material for a plasma display panel, which is characterized in that it comprises 60-90% by mass of ZnO-B2O3 glass powder and 10-40% by mass of filler powder, and the mullite powder accounts for 10% of the filler powder. 20 to 100% by mass. ZnO-B2O3 glass powder, in terms of mass percentage, preferably contains 30-60% of ZnO, 15-35% of B2O3, 3-25% of BaO, 3-20% of SiO2, 0.5-6% of Li2O, Li2O+Na2O+K2O is composed of 1 to 12% glass.

Description

technical field [0001] The present invention relates to a partition wall forming material for a plasma display panel. Background technique [0002] The plasma display panel is a self-luminous flat panel display panel, which has excellent characteristics such as light weight and thin shape, high viewing angle, and can be enlarged, so it is attracting attention as one of the most promising display devices. [0003] In a plasma display panel, a front glass substrate and a rear glass substrate are generally arranged facing each other, and a plurality of barrier ribs (also referred to as barrier ribs) for separating a gas discharge portion are formed in a space between these substrates. As a material for forming the partition wall, a material in which glass powder and ceramic powder are mixed is widely used. In order to prevent deformation of the glass substrate, the material for forming the partition wall must be able to be fired at 600°C. For this reason, glass containing PbO ...
