BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel used for image display, a manufacturing method for sealing a front plate and a back plate thereof, and a glass composition contained in a sealing member.

[0002]

2. Description of the Related Art A conventional plasma display panel will be described below. FIG. 2 is a partial cross-sectional perspective view showing the main configuration of a general plasma display panel. In FIG. 2, 1 is a front plate. Reference numeral 2 denotes a front glass substrate, and a display electrode 5 including a transparent conductive film 3 and a bus electrode 4 is formed on the front glass substrate 2.
Further, the display electrode 5 is a dielectric layer 6 made of dielectric glass.
And a dielectric protection layer 7 made of magnesium oxide.

Reference numeral 8 is a back plate. Reference numeral 9 denotes a rear glass substrate. On the rear glass substrate 9, an address electrode 10, a dielectric layer 11 and a partition wall 12 for covering the address electrode, and a phosphor layer 13 are provided, and 14 is a discharge for enclosing a discharge gas. It is a space. For the color display, the phosphor layer 13 corresponds to any one of three colors of red (R), green (G), and blue (B), and the phosphor layers 13 (R), 13 (G), 13
(B) are arranged in order. Each phosphor layer 13 (R),
13 (G) and 13 (B) are excited to emit light by short wavelength ultraviolet rays (for example, wavelength 147 nm) generated by discharge.

The front plate 1 and the rear plate 8 having such a structure are opposed to each other so that the longitudinal directions of the display electrodes 5 and the address electrodes 10 are orthogonal to each other. FIG. 3 is a front view of the plasma display panel. Front plate 1 and back plate 8
Are sealed by a sealing member 15 made of glass frit at their peripheral portions, and the inside of the facing surface is sealed. Furthermore, the display electrode 5 and the address electrode 10 are connected to an external drive circuit (not shown), respectively.

Hereinafter, a conventional method of manufacturing a plasma display panel will be described. First, a display electrode composed of a transparent conductive film and a bus electrode is formed on the front glass substrate,
A dielectric layer made of dielectric glass is formed so as to cover this, and a protective layer made of magnesium oxide is further formed on the dielectric layer. Next, an address electrode is formed on the back glass substrate, and a dielectric layer and partition walls made of a glass material are formed on the address electrode at a predetermined pitch. A phosphor layer is formed by disposing and firing each color phosphor paste containing a red phosphor, a green phosphor, and a blue phosphor in each space sandwiched between these partition walls.

After that, a sealing member made of glass frit used for sealing the front plate and the rear plate is applied to the periphery of at least one of the front glass substrate and the rear glass substrate, and the resin component and the like in the sealing member. Calcination to remove the. Then, the surface of the front plate on which the display electrode, the dielectric glass layer and the protective layer are sequentially formed is arranged so as to face the rear plate so that the display electrode and the address electrode are orthogonal to each other through the partition wall, and is sealed by firing. The member is softened and fixed to seal the periphery.

After that, the inside of the panel is evacuated while being heated to a predetermined temperature, and after the discharge, the discharge gas is introduced so as to have a predetermined pressure. Further, the panel manufactured as described above is, if necessary, discharged for a predetermined time to stabilize the light emission characteristics and the discharge characteristics.

In the above manufacturing method, in the sealing step using the sealing member made of glass frit, it is necessary to perform heat treatment at a low temperature so as not to hinder other members. The reason is that the glass substrate, electrodes, dielectric layers, and partition walls contain glass materials, and it is necessary to avoid softening or deformation of these glass materials due to heating in the sealing step. It will not happen. Furthermore, it also has the purpose of preventing deterioration of the dielectric protective layer and the phosphor. For these reasons, generally, the processing temperature in the sealing step should be kept at 500 ° C. or lower.

From the above, the glass composition contained in the sealing member used for sealing the front plate and the rear plate of the plasma display panel is typified by lead glass containing PbO as a main component. So-called low melting glass has been used.

[0010]

As described above, in the manufacture of the plasma display panel, the sealing step for sealing the front plate and the back plate with consideration for not affecting other members. It is necessary to select the firing temperature and the appropriate glass composition that constitutes the sealing member.

However, until now, an appropriate temperature condition for sealing using the sealing member has not been clarified. Further, the physical properties required for the glass composition constituting the sealing member have not been clarified, and many trials and errors have been used to determine an appropriate firing temperature and glass composition.

FIG. 1 is a cross-sectional view of the periphery of the plasma display panel, which is a cross-sectional view taken along the address electrodes. If good sealing is performed by the sealing member, good sealing is possible as shown in FIG.

However, if the baking temperature and the sealing member are not appropriate, the sealing member will not be sufficiently softened, and as shown in FIG. 4, the sealing member cannot be sealed due to poor wetting of the front plate or the rear plate. There was something that happened.

On the other hand, if the sealing member is excessively softened by heating in the sealing step, the sealing member may flow and spread as shown in FIG. 5, and the front plate and the rear plate may not be sealed. .

In order to solve such a conventional problem, the present invention provides a plasma display panel in which a front plate and a back plate are well sealed, and a method for manufacturing the same, and a suitable glass constituting a sealing member. It is intended to provide a composition.

[0026]

BEST MODE FOR CARRYING OUT THE INVENTION [First Embodiment] The First Embodiment
The plasma display panel in 1) basically has the same configuration as that in FIGS. 1 to 3 described above, but limits the temperature conditions for sealing the front plate and the back plate. That is, the viscosity of the glass composition constituting the sealing member is 10 ² to
It is characterized in that it is sealed at a temperature of 10 ⁶ Pa · s, and is obtained by the following manufacturing method.

Next, a method of manufacturing the plasma display panel according to the first embodiment will be described.

<Preparation of Front Plate> First, a front glass substrate made of soda lime glass was coated with a paste for forming a transparent conductive film by screen printing, and then a bus electrode for supplementing the conductivity was formed. The paste is applied by screen printing and baked to form a display electrode. The transparent conductive film is made of, for example, ITO,
The bus electrode is, for example, an Ag film or Cr / Cu / Cr 3
It consists of a layer structure film. The transparent conductive film and the bus electrode can be formed by a photo-etching method as well as a screen printing method.

Then, a paste containing a glass for dielectrics (for example, PbO-B ₂ O ₃ based lead glass) is applied by a screen printing method so as to cover the display electrodes, and baked to form a dielectric layer. To do. This dielectric layer may be formed by arranging a dielectric glass formed into a sheet shape with a resin and a solvent or the like on a display electrode and firing the glass.

Further, a protective layer made of magnesium oxide is formed on the surface of this dielectric layer by a vapor deposition method or a CVD method to prepare a front plate.

<Production of Back Plate> Next, a paste for electrodes (for example, Ag or Cr / Cu / Cr) is applied in stripes at regular intervals on a back glass substrate made of soda lime glass by a screen printing method or the like. Then, the address electrodes are formed by firing.

Then, a paste containing a dielectric glass (for example, PbO-B ₂ O ₃ based lead glass) is applied on the address electrodes by screen printing and fired to form a dielectric layer.

Next, partition walls are formed on the dielectric layer for each gap between the address electrodes. The partition wall can be formed by repeatedly screen-printing a paste containing a glass material and firing the paste.

The address electrodes, the dielectric layers, and the partition walls may be formed by a photoetching method or the like.

Next, pastes containing phosphors of red, green and blue colors are applied by screen printing to the spaces between the partition walls and baked to form phosphor layers of respective colors. As an example of each color phosphor used here, a red phosphor is Y ₂ O ₃ : Eu, a green phosphor is Zn ₂ SiO ₄ : Mn,
The blue phosphor includes BaMgAl ₁₀ O ₁₇ : Eu and the like.

<Sealing Step> A glass composition (for example, PbO)
Powder of a sealing member containing —B ₂ O ₃ based lead glass) is kneaded with a resin and a solvent, and the obtained paste is applied to the peripheral portion of the back plate prepared as described above by screen printing.
This is pre-baked at about 350 ° C. to remove the resin component and the like contained in the paste to form a layer of the sealing member. afterwards,
The front plate and the rear plate are overlapped so that the display electrodes and the address electrodes are orthogonal to each other and baked to soften the sealing member and cool and fix it to perform sealing.

The sealing member may be formed on at least one of the front plate and the rear plate, and is not limited to the above method.

Generally, the viscosity of the glass composition decreases with increasing temperature. In order to satisfactorily seal the front plate and the back plate, the sealing member containing the glass composition is heated,
It needs to be softened appropriately. In order for the glass composition to be sufficiently softened so that the front plate and the rear plate are wetted well, and the good sealing can be achieved, the viscosity is 1
Sealing is preferably performed under a temperature condition of 0 ⁶ Pa · s or less.

However, when the viscosity of the glass composition becomes low, the fluidity of the sealing member increases and the shape cannot be maintained, and it spreads as shown in FIG. 5 and it becomes impossible to seal the front plate and the back plate. . In order to satisfactorily seal the front plate and the back plate, it is preferable to seal the glass composition under a temperature condition where the viscosity of the glass composition is 10 ² Pa · s or more.

From the above, the baking in the sealing step in the plasma display panel is preferably performed at a temperature at which the viscosity of the glass composition constituting the sealing member is 10 ² to 10 ⁶ Pa · s. More preferably, 10
^{It is recommended} to seal at a temperature of ^2.5 to 10 ⁵ Pa · s.

The reason why the temperature of the sealing step is limited within the range of the viscosity of the glass composition will be described in detail in Example 1 described later.

Needless to say, it is necessary to prevent other members of the plasma display panel from being adversely affected by heat such as deterioration and deterioration in the sealing step. In a general plasma display panel, it is desirable to perform sealing at a temperature of 500 ° C. or lower.

The sealing with the sealing member containing the glass composition is not limited to the method using the paste kneaded with the resin and the solvent as described above. For example, a stick-shaped or frame-shaped sealing member made of a glass composition is prepared, and the sealing member is placed on the peripheral portion of the back plate and heated and softened to perform the same sealing as described above.

Further, since the firing temperature in the sealing step is limited to 500 ° C. or lower, the glass composition contains Pb, Bi and Z.
It is preferable to use a glass composition containing at least one oxide selected from n, P, Sn, Te, V and Cu.

The above-mentioned sealing member may be composed of only the glass composition, but for some purposes, it is appropriately selected.
It may be a mixture with a low expansion ceramics filler, a pigment, or the like.

Further, if the glass composition is appropriately softened at the time of sealing and can be hermetically sealed, there is no problem with crystallization after sealing, and crystallized glass may be used.

<Completion of Plasma Display Panel> After the above, the gas is once released by firing while exhausting from the internal space of the sealed front plate and back plate. And
A discharge gas is sealed in this internal space at a predetermined pressure. Next, driving circuits for driving the display electrodes and the address electrodes are connected to complete the plasma display panel.

The members used in the plasma display panel described above can basically be made of conventionally used materials.

The structure of the plasma display panel is basically as described above, but is not limited to these.

Further, the present invention does not limit the discharge method of the plasma display panel, but may be AC type or D type.
It can be applied to any of C type.

[Second Embodiment] The plasma display panel according to the second embodiment is basically the same as that shown in FIG.
3 to 3, but the glass composition constituting the sealing member used for sealing the front plate and the rear plate is limited to those having a viscosity in a specific range at the temperature during firing. That is, at the firing temperature of the sealing step, 10 ² to
It is characterized in that it is sealed with a sealing member containing a glass composition having a viscosity of 10 ⁶ Pa · s, and is obtained by the following production method.

Next, a method of manufacturing the plasma display panel according to the second embodiment will be described. In addition,
The manufacturing of the front plate, the manufacturing of the rear plate, and the completion of the plasma display panel other than the sealing step are the same as the method described in the first embodiment, and therefore the description thereof is omitted.

<Sealing Step> A glass composition (for example, PbO-B) is formed on the peripheral portion of the back plate manufactured in the same manner as in the first embodiment.
A paste obtained by kneading a powder of a sealing member containing ₂ O ₃ based lead glass) with a resin and a solvent is applied by screen printing. This is pre-baked at about 350 ° C. to remove the resin component and the like contained in the paste to form a layer of the sealing member. After that, the front plate and the rear plate are overlapped so that the display electrodes and the address electrodes are orthogonal to each other, and baked to soften the sealing member and cool and fix it for sealing.

The sealing member may be formed on at least one of the front plate and the rear plate, and is not limited to the above method.

As described above, in the sealing step, it is necessary to perform the heat treatment at a temperature below the temperature at which other members are not hindered. Therefore, the firing temperature is limited depending on the members used. On the other hand, impurities such as impure gas that may adversely affect the emission characteristics and discharge characteristics of the plasma display panel may be adsorbed on each member of the front plate and the back plate and the sealing member. In order to remove it in the sealing step, it is desirable to perform firing at a certain temperature or higher. For these reasons, the firing temperature in the sealing step is generally determined in the range of 400 to 500 ° C.

When the firing temperature is limited as described above, a suitable sealing member can be selected by defining the viscosity of the glass composition constituting the sealing member.

When a glass composition having a viscosity of 10 ⁶ Pa · s or less at the firing temperature is selected, the glass composition is sufficiently softened in the sealing step, the front plate and the rear plate are well wetted, and the sealing is excellent. It is preferable because it can be worn.

However, if the viscosity of the selected glass composition at the firing temperature is less than 10 ² Pa · s, the shape cannot be maintained due to the high fluidity of the sealing member, and it spreads as shown in FIG. It becomes impossible to seal the front and back plates.

From the above, the glass composition according to the second embodiment is 10 ² to 1 at the firing temperature.
It is a glass composition having a viscosity of 0 ⁶ Pa · s.
More preferably, it is 10 ^2.5 to 10 ⁵ P at the firing temperature.
A glass composition having a viscosity of a · s is preferable.

The reason why the range of the viscosity of the glass composition is limited as described above is as follows.
Will be described in detail.

Here, the sealing with the sealing member containing the glass composition is not limited to the method using the paste kneaded with the resin and the solvent as described above. For example, a stick-shaped or frame-shaped sealing member made of a glass composition is prepared, and the sealing member is placed on the peripheral portion of the back plate and heated and softened to perform the same sealing as described above.

Further, since the firing temperature in the sealing step is limited to 500 ° C. or lower, the glass composition contains Pb, Bi and Z.
It is preferable to use a glass composition containing at least one oxide selected from n, P, Sn, Te, V and Cu.

Although the above-mentioned sealing member may consist of only the glass composition, it may be appropriately used for a certain purpose.
It may be a mixture with a low expansion ceramics filler, a pigment, or the like.

Further, if the glass composition is appropriately softened at the time of sealing and can be hermetically sealed, there is no problem even if it is crystallized after sealing, and crystallized glass may be used.

After the front plate and the rear plate are sealed as described above, the plasma display panel is completed in the same manner as in the first embodiment.

It should be noted that the members used in the plasma display panel described above can basically be made of conventionally used materials.

The structure of the plasma display panel is basically as described above, but is not limited to these.

Further, the present invention does not limit the discharge method of the plasma display panel, but may be an AC type or a D type.
It can be applied to any of C type.
