Problems solved by technology

However, in this case, each of the vertical and horizontal barrier ribs formed perpendicularly to each other is formed by a patterning process using photoresist or sandblasting, which is a manufacturing method requiring a large number of steps, so there are The problem of poor work efficiency
[0006] In this way, in a PDP, especially in a honeycomb type PDP, there is a problem that it is difficult to simply ensure a path for introducing discharge gas.

Abstract

A composition for a dielectric of a plasma display panel, which is formed by laminating two layers, and the first layer includes an inorganic powder, a binder resin, and a light absorber that absorbs light of a predetermined wavelength, and the second layer includes an inorganic Powder, binder resin, photopolymerizable monomer and photopolymerization initiator. Moreover, this invention provides the composition for dielectric bodies used for forming a 1st layer and a 2nd layer. In addition, the present invention provides a method for forming a dielectric body, that is, a first layer and a second layer are provided on a glass substrate, the second layer is irradiated with light, developed, patterned, and the first layer and the second layer are formed. The 2 layers are fired together.

Description

Technical field [0001] The present invention relates to a dielectric composition for forming a dielectric of a plasma display panel, a laminated body for a dielectric, and a method for forming a dielectric. Background technique [0002] The plasma display panel (hereinafter abbreviated as PDP) is constructed in such a way that fluorescent light is formed in a plurality of small spaces formed by two glass substrates and partition walls (barrier ribs) provided between the substrates. The body, the electrode, and the dielectric body made of inorganic materials, where discharge gas is injected. In a PDP, each minute space is one pixel. When the electrodes are energized, discharge starts through the dielectric, and the ultraviolet rays generated when the excited discharge gas returns to the substrate state cause the phosphor to emit light. Compared with the past liquid crystal display or CRT display, such a PDP is suitable for large screens and is gradually being put into practical us...
