Problems solved by technology

If a warp occurs on the substrate, when assembling the equipment, especially in the sealing process, the vacuum container cannot be obtained because the seal cannot be obtained, and as a result, defects in obtaining the device and defects in ensuring accuracy will occur.

Embodiment 1-4

[0110] In order not to contain Pb and Bi, 0 to 12 mol % of an alkali metal oxide was contained, and the composition shown in Table 1 was used for glass. After melting this glass composition at 1300° C., it was rapidly cooled and pulverized with a ball mill. The particle size of the obtained glass powder was measured with a MICRO TRACK particle size analyzer, and the glass transition point and softening point were measured with TG-DTA (Model TG / DTA320 manufactured by SEIKO Electronics Co., Ltd.). The particle size, glass transition point and softening point of the obtained glass powder are listed in Table 1. In addition, the content of each component in Table 1 is converted into an oxide, and the unit is mol%.

[0111] The glass powder is press-formed into a rod, and fired at 580°C for 30 minutes to obtain a sample with a diameter of 4mm and a length of 10mm. The coefficient of thermal expansion of this sample was measured with TMA (TMA320 type manufactured by Seiko Electroni...

Abstract

PROBLEM TO BE SOLVED: To provide a glass composition which is used for forming a dielectric body or a partition wall of a plasma display panel, a fluorescent indicator tube or a field emission display, does not contain harmful matters and causes little environmental load, and to provide a glass paste composition which can greatly reduce the warping of the substrate by using this glass composition. ŽSOLUTION: The glass composition is one that does not substantially contain Pb and Bi and has a glass transition point of 430°C-540°C, and it is characterized by containing 1-15 mol% of SiO<SB>2< / SB>, 10-50 mol% of B<SB>2< / SB>O<SB>3< / SB>, 30-50 mol% of ZnO, 0-12 mol% of an oxide of an alkali metal:R<SB>2< / SB>O (in the formula, R exhibits at least one alkali metal selected from among K, Na and Li), and 3-20 mol% of BaO in terms of oxides.

Description

technical field [0001] The present invention relates to a glass composition and a glass paste composition. Specifically, it relates to the formation of dielectrics or barrier ribs for use in plasma displays, vacuum fluorescent displays, or field emission displays, and does not contain harmful substances such as Pb. A glass composition with a low environmental load, and a glass paste composition capable of greatly reducing warpage of a substrate by using the glass composition. Background technique [0002] A plasma display (hereinafter referred to as PDP) attracts attention as a large flat panel display, is put into practical use as a large television image receiver, and is rapidly spreading. Vacuum fluorescent display (hereinafter referred to as VFD) is used as a display device for characters and symbols, and is used as a display device for automobiles, audio equipment, digital multimeters and other measuring instruments. In addition, field emission display (hereinafter refe...
