The address electrodes 6 are formed by printing Ag paste on the inner surface of the rear glass substrate 1. Each phosphor layer 5R, 5G, 5B is formed by printing a paste containing a phosphor substance. This printing is performed on the phosphor layers 5R and 5R.
This is performed three times for each of G and 5B for each cell 3. The red phosphor contained in the phosphor layer 5R may be, for example, Y ₂ O ₃ : Eu or (Y, Ga) B.
O ₃ : Eu is used. Further, as the green phosphor contained in the phosphor layer 5G, for example, Zn ₂ SiO ₄ : Mn is used. The blue phosphor contained in the phosphor layer 5B is, for example, BaMgAl ₁₆ O ₂₇ : Eu, or
MgAl ₁₄ O ₂₃ : Eu is used. Each phosphor layer 5R,
The film thickness of 5G and 5B is about 30 [μm], and the phosphor layers 5R, 5G, and 5B are applied to the inner surface of the rear glass substrate 1 and the surface (that is, the side surface) of the partition wall 4. As a result, as shown in FIG. 1, each phosphor layer 5R, 5R
G and 5B are provided on three surfaces in the cell 3 (on the rear glass substrate 1 and on the respective surfaces of the partition walls 4 facing each other).

The width BM of the black matrix 11 is set so that θ ₂ = 90 ° is satisfied (that is, the visible light 26 from the adjacent cell 3 is not mixed) when the refraction angle of the light 26 is θ ₂ .

Here, tan θ ₁ = BM / T and the refractive index n ₁ = sin θ ₂ / sin θ ₁ = sin (90 °) / sin θ ₁ = 1.536 (in the case of BM-7 glass),
To prevent the visible light 26 from admixing from the adjacent cell, T <
Black matrix 1 so as to satisfy 1.16 × BM
It is desirable to set the width BM to 1.

Although not shown, the PD of the first embodiment
In P, the front glass substrate 2 and the rear glass substrate 1 are sealed in the vicinity of the outer periphery with glass solder such as frit glass. This seal is made from 450 frit glass.
It is carried out by heating at [° C] for 30 minutes. After being sealed, heating and evacuation of the cells 3 are performed, and a mixed gas such as Ne-Xe is supplied to each cell 3, for example, 40
0 [Torr] is enclosed.

When the PDP having the above structure is operated to display an image, the display electrodes 7a and 7b are provided with, for example, 1
An alternating voltage of 80 [V] is applied. At this time, plasma is generated in the cell 3, and the phosphor layers 5R, 5G, 5B and the phosphor layer 10 which have received the ultraviolet rays emitted during this discharge are received.
Visible light is emitted from R, 10G, and 10B. For example,
Visible light emitted from the phosphor layer 5R is emitted through the protective film 9, the dielectric layer 8, the display electrodes 7a and 7b, the front glass substrate 2, and the phosphor layer 10R provided in the openings of the black matrix 11. , Is recognized by the viewer V as display light. At the same time, the visible light emitted from the phosphor layer 10R is also recognized by the viewer V as display light.

Next, the brightness when the phosphor layer 10R is added will be schematically described. FIG. 5 shows the PDP of FIG.
It is an explanatory view for explaining the amount of light emitted from. Here, for convenience, the height of the portion of the phosphor layer 5R formed on the surface of the partition wall 4 (actually 0.150 [mm]).
Is regarded as a, and the width of the bottom surface of the phosphor layer 5R (actually, 0.
34 [mm]) is regarded as 2a. The amount of visible light emitted from the phosphor layer 5R to the front glass substrate 2 side is L ₁
Where L ₂ is the amount of visible light emitted from the phosphor layer 10R to the viewer V side, and the ratio of the visible light emitted from the phosphor layer 5R to the outside through the front glass substrate 2 and the like. The (visible light transmittance) is x, and the ratio of ultraviolet rays generated by the plasma in the cell 3 to the phosphor layer 10 through the front glass substrate 2 (ultraviolet transmittance) is y. Also, a PDP without the phosphor layer 10R (comparative example)
Let L ₀ be the amount of visible light emitted toward the viewer V, and L _A be the amount of visible light emitted toward the viewer V by the PDP of the first embodiment.

The visible light emitted from the portion of the phosphor layer 5R on the partition wall 4 has a width 2a (a portion on the two partition walls 4, that is, a
+ A = 2a), but the ratio of the light emitted toward the viewer V (that is, the ratio contributing to the improvement in the brightness perceived by the viewer V) is about half of that, and The amount of light that is emitted can be regarded as a value a. In addition, the phosphor layer 5R
Visible light emitted from the portion on the rear glass substrate 1 can be regarded as a value 2a corresponding to the width 2a. Therefore, P of the comparative example
Light amount L emitted from one cell of DP toward the viewer V
_{It can be considered that 0} = 2a + a = 3a.

On the other hand, the phosphor layer 1 of the PDP of the first embodiment
The amount L ₂ of visible light emitted from 0R that contributes to the improvement of luminance can be regarded as a value obtained by multiplying the value 2a corresponding to the width 2a by the transmittance y of ultraviolet rays, that is, L ₂ = 2a · y. Further, of the visible light emitted from the phosphor layer 5R of the PDP of the first embodiment, the amount L ₃ of light that is emitted toward the viewer V through the phosphor layer 10R is emitted from the phosphor 5R. Light quantity L ₁ = 3a (light quantity L ₁ is equal to light quantity L _{0 of the} comparative example)
Multiplied by the visible light transmittance x, that is, L ₃ = L ₁ · x =
Since L ₀ · x = 3a · x, the PDP of the first embodiment
The light quantity L _{A is} L ₂ = L ₂ + L ₃ . Therefore, L _A / L ₀ = (L ₂ + L ₃ ) / L ₀ = (2a · y + 3a ·
x) / 3a> 1 (that is, in order to increase the brightness as compared with the comparative example), it is necessary to satisfy the following conditional expression 1 2y + 3x> 3.

From conditional expression 1, when y = 1, x> 1
/3=0.3333 ... and the phosphor layers 5R, 5G, 5
It can be seen that the amount of attenuation permitted when visible light from B is transmitted through the front glass substrate 2 or the like is about 67% or less. When y = 0.5, x> 2/3 = 0.6666
It can be seen that the visible light from the phosphor layers 5R, 5G, and 5B has an allowable attenuation amount of about 33% or less when passing through the front glass substrate 2 and the like. Further, when y = 0.25, x> 2.5 / 3 = 0.8333 ..., which is allowed when visible light from the phosphor layers 5R, 5G, 5B is transmitted through the front glass substrate 2 and the like. It can be seen that the amount of attenuation is about 17% or less.

As described above, the PD of the first embodiment
According to P, since visible light is emitted not only from the phosphor layers 5R, 5G, 5B but also from the phosphor layers 10R, 10G, 10B, it is possible to improve the brightness without increasing the driving power. it can. In addition, the phosphor layers 10R, 10
