Problems solved by technology

However, in order to realize the protective performance of protecting the dielectric layer 106 from the impact of ions generated by the gas discharge, and to reduce the discharge voltage so that the responsiveness of the discharge is fast, the crystallographic structure of the protective film 107 or various physical properties are proposed. In the scheme of improving the characteristics, it is still difficult to say that the satisfactory performance and characteristics have been obtained.

Abstract

Disclosed is a PDP (21) comprising a front plate (22) having a plurality of display electrodes (4) formed thereon and covered with a first dielectric layer (6) and a protective film (7), and a back plate (23) having a plurality of address electrodes (10) formed thereon so as to be perpendicular to the display electrodes (4) and covered with a second dielectric layer (a foundation dielectric layer (9)). In this PDP (21), the protective film (7) has a structure wherein granular crystals having large grain sizes gather together and the spaces between adjacent crystals are small.

Description

technical field [0001] The present invention relates to a plasma display panel (hereinafter referred to as a PDP) widely used as a flat panel display for displaying public information such as large televisions or advertisements and information, and a method for manufacturing the same. In particular, the present invention relates to a plasma display panel having a protective film capable of maintaining excellent display quality even with low output and long-time operation, and a method for manufacturing the same. Background technique [0002] In recent years, as a large flat-panel display device, a PDP that excites a phosphor to emit light by ultraviolet rays generated by a rare gas discharge and is used for image and video display has been developed targeting a large product with a diagonal of 1 m or more. The development of PDP is accelerated. As a display device for information processing represented by computers, or as a large-scale television receiver or a monitor for pu...
