Embodiment 1

[0066] 1. The overall structure of the screen

[0067] use figure 1 The overall structure of the AC-type PDP of Example 1 will be described. figure 1 is a diagram showing part of the AC-type PDP1.

[0068] Such as figure 1 As shown, the AC-type PDP 1 has a structure in which a front panel 10 and a rear panel 20 are arranged to face each other with a certain distance therebetween, and the space between the panels is divided into a plurality of discharge spaces 40 by barrier ribs 30 .

[0069] The front panel 10 has a structure in which a plurality of display electrodes 12 are arranged in stripes on one main surface (lower side in the figure) of a front glass substrate 11, and a first dielectric layer 13 and a dielectric protective film are sequentially stacked on this surface. 14.

[0070] A plurality of address electrodes 22 are arranged in stripes on the rear glass substrate 21 facing the front panel 10 of the rear panel 20, and then a second dielectric layer 23 coveri...

Embodiment 2

[0162] use Figure 13 The AC-type PDP2 of Example 2 will be described. Figure 13 A cross-sectional view of an AC-type PDP 2 corresponding to only one light-emitting unit is shown.

[0163] Such as Figure 13 As shown, the phosphor film (layer) formed in the AC type PDP 2 is only the first phosphor film 31 formed on the surface of the front panel 10 . That is, no phosphor film (layer) is formed on the rear panel 20 and barrier ribs 30 .

[0164] Except for this point, the AC-type PDP2 has the same structure as the above-mentioned AC-type PDP1, and is manufactured by the same method.

[0165] In addition, the point that the first phosphor film 31 has a notch 31a is also the same as that of the above-mentioned AC type PDP 1 (not shown).

[0166] The AC-type PDP 2 can obtain sufficiently high luminance without forming a phosphor layer composed of conventional phosphor particle groups on the surfaces of the rear panel 20 and the barrier ribs 30 . As described above, this is p...

Embodiment 3

[0173] use Figure 15 The AC-type PDP3 of Example 3 will be described.

[0174] Such as Figure 15 As shown, the AC-type PDP3 and the above-mentioned AC-type PDP2 only form the first phosphor film 31 on the front panel 10, which is the same. The difference is that the address electrodes 22 and the second dielectric layer are formed on the front panel 10. 23 , forming the display electrodes 12 , the first dielectric layer 13 and the dielectric protection film 14 on the rear panel 20 .

[0175]When this structure is adopted, in order not to affect the transmission of visible light, the address electrodes 22 and the second dielectric layer 23 are formed of materials with high transmittance of visible light. Specifically, the address electrode 22 uses ITO (Indium Tin Oxide) and SnO 2 and other transparent electrodes, the second dielectric layer 23 is made of lead glass mainly composed of lead oxide. Because the address electrode 22 is formed on the short side direction of the ...

Abstract

A plasma display panel operated at a high luminous efficiency even with a fine cell structure and its manufacturing method. An AC type PDP1 has a phosphor film 31 comprising a thinned crystal over the surface of a dielectric protecting film 14 in a front panel 10 The phosphor film 31 is a film formed by EB evaporation, the film thickness of which is set in a range where a sufficient luminous efficiency and a visible light penetration efficiency can be secured when the phosphor film 31 is irradiated with ultraviolet rays.

Description

technical field [0001] The invention relates to a plasma display screen and a manufacturing method thereof. Background technique [0002] Plasma display panels (hereinafter referred to as "PDP") are broadly classified into direct current (DC) type and alternating current (AC) type, and the AC type, which is suitable for large-scale display, is now becoming the mainstream. [0003] Figure 16 It is a perspective view (partial sectional view) showing an example of an AC-type PDP. [0004] Such as Figure 16 As shown, a plurality of display electrodes 62 are arranged in stripes on the surface of the front glass substrate 61 . A dielectric layer 63 is formed on the surface on which the display electrodes 62 are disposed, covering them as a whole. In addition, a dielectric protection film 64 is formed on the surface of the dielectric layer 63 . [0005] On the other hand, a plurality of address electrodes 72 are arranged in stripes on the surface of rear glass substrate 71 fac...
