Embodiment Construction

[0023] Hereinafter, an embodiment of the plasma display panel of the present invention will be described in detail with reference to the accompanying drawings.

[0024] figure 1 is an enlarged perspective view of a portion of a plasma display panel of the present invention, generally indicated by reference numeral 20 . As shown in the figure, the structure of the display panel 20 of the present invention is the same as Figure 5 The structure of the plasma display panel 20' shown in is basically the same. Therefore, the description of the structure of the plasma display panel 20 is omitted, and in figure 1 and Figure 5 The same parts and accessories having the same function in have the same reference number.

[0025] The difference between the plasma display panels 20 and 20' lies in the materials of the base glass layer and the ribs. Specifically, although the material of the base glass layer 8 and the ribs 9 of the plasma display panel 20' in the prior art has a white ...

Abstract

A plasma display panel has spaced apart and parallel first and second substrates substrate. A base glass layer is provided on one surface of the second substrate confronting to the first substrate. A plurality of spaced apart parallel ribs are positioned on the base glass layer and between first and second substrates. Each rib defines a channel with another neighboring rib. A plurality of phosphor capable of emitting light are provided, each of which being positioned in the channel. In particular, the base glass layer and / or ribs are made of material substantially impermeable to light.

Description

technical field [0001] The present invention relates to a display element and a plasma display panel especially for image display of televisions and computers. Background technique [0002] exist Figure 5 A conventional AC plasma display panel is described in . like Figure 5 As shown, a plurality of scan electrodes 4 and sustain electrodes 5 are formed on a first insulating substrate 1 parallel to each other. Scan electrodes 4 and sustain electrodes 5 are covered by a dielectric layer 2 and a protective layer 3 . A plurality of data electrodes 7 parallel to each other and perpendicular to the scan electrodes 4 and the sustain electrodes 5 are formed on the second insulating substrate 6 facing the first insulating substrate 1 . The data electrodes 7 are covered by a base glass layer 8 made of white material. Formed on the base glass layer 8 are a plurality of ribs 9 also made of white material. Ribs 9 are arranged such that each rib cooperates with an adjacent rib to de...
