Problems solved by technology

However, when the Xe concentration is increased in this way, there is also the problem that initialization bright spots are prone to occur.
[0014] The second problem is that there are differences in the secondary electron emission characteristics of the discharge cells of each color in the PDP.
[0015] That is to say, in the conventional PDP, phosphor materials of any one of R, G, and B colors having different compositions are used for each of the phosphor layers of the respective colors. , there is a difference in discharge characteristics caused by the secondary electron emission characteristics of each phosphor material
Such a difference adversely affects the image display characteristics of the entire panel, so there is a problem that should be improved
[0016] The third problem is that when the PDP is driven, part of the vacuum ultraviolet rays generated from the discharge gas is absorbed by the magnesium oxide layer, and it is difficult to improve the luminance.
[0021] However, it is difficult to say that the occurrence of initialization bright spots can be effectively suppressed by using any of the above-mentioned existing technologies, and it is difficult to effectively solve this problem.
[0022] In addition, it is very important to obtain a PDP with excellent image display performance while suppressing the generation of initialization bright spots, improving luminance, and eliminating the difference in discharge characteristics between the discharge cells of each color, but it is also considered to be very important. Difficult to achieve

Abstract

A plasma display panel exhibiting excellent image display performance by suppressing generation of an initialization bright point through modification of a phosphor layer, and by eliminating variation in discharge characteristics between the discharge cells of respective colors. In the plasma display panel, in which the luminance is enhanced by accelerating emission of visible light through utilization of UV-rays emitted in the discharge space even on the front panel side. Specifically, the phosphor layer (14) is composed of a phosphor component, and MgO fine particle group (16) arranged principally in the phosphor layer and on the surface (140) facing the discharge space to be exposed in order to impart secondary electron discharge characteristics. The MgO fine particle group (16) is composed of MgO fine particles (16a-16d) having a crystal structure surrounded by specific two kinds of orientation faces consisting of the (100) face and the (111) face, or specific three kinds of orientation face consisting of the (100) face, the (110) face and the (111) face.

Description

technical field [0001] The present invention relates to a plasma display panel used in various displays and a method of manufacturing the same. Background technique [0002] In recent years, expectations for high-definition, high-quality, and large-screen TVs including high-definition TVs and HD-TVs have been increasing.
