Problems solved by technology

[0004] However, the glass disclosed in Japanese Patent Application Laid-Open No. 2001-163635 contains an alkali metal oxide for the purpose of lowering the softening point of the glass. Therefore, the peelability of the dry film protection film is deteriorated, and it is difficult to use the sandblasting method. next door problem

Embodiment Construction

[0010] The barrier rib forming material for plasma display panels of the present invention contains low melting point ZnO-B 2 O 3 —SiO 2 The glass-like powder is the main component. Because only ZnO, B 2 O 3 And SiO 2 The three components have a higher melting point than PbO glass. Therefore, in ZnO-B 2 O 3 —SiO 2 In glass-like glass, Li is added at 3% or more mol% 2 O, Na 2 O, K 2 The alkali metal oxide of O lowers the melting point of the glass. In addition, due to the addition of alkali metal oxides, the releasability of the dry film protective film tends to decrease and it is difficult to form partition walls by sandblasting. But by controlling the content of alkali metal oxides below 10%, and reducing B 2 O 3 / (Li 2 O+Na 2 O+K 2 The ratio of O) is adjusted so that the molar ratio is in the range of 2.3 to 8.0, and the decrease in the peelability of the dry film protective film is suppressed, whereby the partition wall can be formed by the sandblasting method.

Abstract

The invention provides material for partition wall of plasma display panel and glass composite for the wall, which can be sintered in the same temperature with the traditional material for partition wall without containing PbO. The material is formed by sand blasting and restrains the decrease of the stripping of the dry protection film even if the material contains alkaline metal oxides. The material for partition wall of plasma display panel of the invention contains glass powders and ceramic powders, and is characterized in that: the glass powder is composed of glass containing 35-60 mol %ZnO, 15-40 mol% B2O3, 1-20 mol% SiO2, 0-5 mol% Al2O3, 0-10 mol% BaO, 0-8 mol% Li2O, 0.02-10 mol% Na2O, 0.01-5 mol% K2O, Li2O+Na2O+K2O is 3-10 mol%, B2O3 / (Li2O+Na2O+K2O) is 2.5-8.0, K2O / Na2O is less than 0.50, and without PbO.

Description

Technical field [0001] The present invention relates to a partition wall forming material for a plasma display panel and a glass composition for a partition wall forming material. Background technique [0002] The plasma display panel is a self-luminous flat-panel display device with excellent characteristics such as thinness and large viewing angle. In addition, because it can achieve a large screen, it has attracted 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 opposite to each other, and a plurality of partition walls (also referred to as barrier walls) for dividing a gas discharge portion are formed in a space between these substrates. As a method of forming partitions, sandblasting is generally used. After partitions are formed on a glass substrate, a dry film protective film is formed on the glass substrate. After exposure and development, unnecessary parts ...
