Problems solved by technology

However, when impurities are mixed into the protective layer to improve the electron emission characteristics, at the same time, charges are accumulated on the surface of the protective layer, and the decay rate of the charge with time when it is used as a memory function becomes large. Therefore, Countermeasures such as increasing the applied voltage to suppress this problem are required
[0009] As described above, as the characteristics of the protective layer, there is a problem that it must have two opposite characteristics: high electron release ability and low decay rate of charges that function as a memory, that is, high charge retention characteristics.

Embodiment approach

[0047] figure 1 It is a perspective view showing the structure of the PDP 1 manufactured according to the PDP manufacturing method in the embodiment of the present invention. The front panel 2 composed of the front glass substrate 3 and the like and the back panel 10 composed of the back glass substrate 11 and the like are arranged to face each other, and the outer periphery is hermetically sealed by a sealing material composed of glass frit or the like. Discharge gases such as neon (Ne) and xenon (Xe) are enclosed in the discharge space 16 inside the PDP 1 at a pressure of 53.3 kPa to 80.0 kPa. On the front glass substrate 3 of the front panel 2, a pair of strip-shaped display electrodes 6 and black stripes (light-shielding layers) 7 composed of scan electrodes 4 and sustain electrodes 5 are arranged in parallel rows. A dielectric layer 8 that functions as a capacitor is formed on the front glass substrate 3 so as to cover the display electrodes 6 and the light shielding layer...

Abstract

The present invention provides a method for producing a plasma display panel. In order to realize a low-power-consumption plasma display panel having display performance with high fineness and high luminance, after forming a base film (91), a metal oxide paste composed of metal oxide particles, an organic component containing a photopolymerization initiator, a water-soluble cellulose derivative and a photopolymerizable monomer, and a diluent solvent is applied thereto, and agglomerated particles wherein a plurality of metal oxide particles are agglomerated are adhered to the base film (91) by exposing, developing and firing the paste film. The metal oxide paste contains the metal oxide particles in an amount of not more than 1.5% by volume.

Description

Technical field [0001] The present invention relates to a method of manufacturing a plasma display panel. Background technique [0002] Plasma display panels (hereinafter referred to as PDPs) can display at high speeds even in flat panel displays (FPDs) and are easy to be enlarged. Therefore, they are widely used in fields such as video display devices and publicity display devices. [0003] An AC-driven surface discharge type PDP generally adopts a three-electrode structure, and is formed by arranging two glass substrates, a front panel and a back panel, facing each other at a predetermined interval. The front panel is composed of the following parts: display electrodes composed of striped scan electrodes and sustain electrodes formed on a glass substrate; a dielectric layer that covers the display electrodes and functions as a capacitor for accumulating charges; and is formed on the dielectric layer A protective film with a thickness of about 1 μm. On the other hand, the back p...
