Description

Flat panel display

Technical field

The present invention relates to a flat panel display device called a PDP. Background art

The most common structure of a flat display device called a conventional PDP (Plasma Display Panel) is a so-called two-electrode opposed discharge PDP. The two-electrode facing discharge type PDP is opposed to each other across a discharge space and intersects with each other on a front-side and a rear-side glass substrates which are arranged in parallel with each other and constitute a tube body filled with a discharge gas. First and second electrodes each comprising a plurality of striped electrodes are provided, and the first and second electrodes are selectively applied between the plurality of electrodes constituting the respective electrodes. In addition, a discharge is generated at the intersection of each of the selected electrodes, and light emission display is performed.

Such a PDP is originally a monochromatic light-emitting display device. However, a red, green, and blue light-emitting phosphor layer is sequentially and cyclically deposited on a predetermined portion in a tube to emit ultraviolet light generated based on discharge. By irradiating the phosphor layer to emit light, a color PDP can be formed.

In such a color PDP, the phosphor layer must be formed on a portion of the tube in which scattered matter from electrodes and the like generated by discharge or ion bombardment is difficult to adhere. The formation location is limited. Further, depending on the location where the phosphor layer is formed, there is a possibility that a sufficient emission luminance cannot be obtained from the phosphor layer. The conventional color PDP has a two-electrode surface discharge type color filter in which XY electrodes are arranged so as to cross each other on the same plane of the rear glass substrate, and a phosphor layer is formed on the front glass substrate. There is also a PDP o Hereinafter, the structure of such a conventional two-electrode surface discharge type color PDP will be described with reference to FIG. 1 and FIG. A first electrode (X electrode) 2 composed of a plurality of striped electrodes is disposed on the rear glass substrate 1, and a second electrode (Y electrode) composed of a plurality of striped electrodes is disposed on the X electrode 2. 4) are arranged so as to cross each other (orthogonal), and the X electrodes 2 and

An insulating layer 3 that electrically separates the X electrode 2 and the Y electrode 4 is interposed at the intersection of the Y electrode 4 and extends over the surfaces of the X electrode 2 and the Y electrode 4 and the surface of the rear glass substrate 1. The X electrode 2 and the Y electrode 4 are covered by forming the dielectric layer 7 so as to form AC electrodes. Reference numeral 20 in FIG. 2 indicates a discharge path between the X electrode 2 and the Y electrode 4.

Although not shown, red, green and blue light-emitting phosphor layers are sequentially and cyclically deposited on the front glass substrate.

In the color PDP having such a structure, the separation from the phosphor layer is ensured, so that the scattered matter from the discharge electrodes, that is, the X electrodes 2 and the Y electrodes 4 fly to the phosphor layer side. Never.

This phosphor layer is a so-called transmissive type in which light emitted from the phosphor layer, which emits light upon receiving ultraviolet rays based on discharge, passes through the phosphor layer and exits from the front glass substrate side. Since it is a phosphor layer, it has the feature that the color purity of emitted light is good.

Next, a conventional color PDP called a three-electrode surface discharge PDP will be described with reference to FIG. On the rear glass substrate 1, a first electrode (X electrode) 2 composed of a plurality of stripe-shaped electrodes extending in parallel with each other and extending in the vertical direction is formed, and the X electrode 2 is covered. As a result, a dielectric layer 35 is formed on the rear glass substrate 1 and over the surface of the X electrode 2. Partition walls 31 are provided on the dielectric layer 35 between the striped electrodes constituting the X electrode 2. Then, between the side surface of the bulkhead 3 1 and the adjacent bulkhead 3 1 A phosphor layer 9 is formed over the dielectric layer 35.

On the front glass substrate (not shown), a plurality of strip electrodes arranged so as to be opposed to and orthogonal to the plurality of strip electrodes constituting the X electrode 2 on the rear glass substrate 1 side are provided. 2 electrode (Y electrode) 4 and a sustain electrode 34 composed of a plurality of strip-shaped electrodes which are arranged in parallel and close to the respective electrodes constituting the Y electrode 4 and are connected to each other. It is formed.

A dielectric layer 33 is formed on the Y electrode 4 and the sustain electrode 34, and a protective layer 32 is formed on the dielectric layer 33 to form an AC discharge electrode. are doing.

In this PDP, the address discharge between the X and Y electrodes 2 and 4 is taken over by the sustain discharge between the Y electrode 4 and the sustain electrode 34 on the front glass substrate side. Since the X electrode 2 is not related to the sustain discharge, the discharge layer does not damage the phosphor layer similarly to the above-mentioned two-electrode surface discharge type PDP.

The phosphor layer 9 is a so-called reflective phosphor screen in which light emitted from the phosphor layer, which emits light by receiving ultraviolet rays based on discharge, is radiated from the surface of the phosphor layer 9 to the outside through the front glass substrate. It has the feature of high brightness.

Next, many problems that need to be improved over the conventional PDP described above will be described. First, regarding the above-mentioned two-electrode surface discharge type PDP, as is clear from the cross-sectional partial view of FIG. 2, the X electrode as the lower discharge electrode and the Y electrode 4 as the upper electrode are used. However, since it is apparently divided into two parts, the following problems occur.

That is, as shown in FIG. 2, a pair of discharge paths 20 for the X electrode 2 to the Y electrode 4 are formed on both sides of the Y electrode 4. In this case, due to variations in the characteristics of the X and Y electrodes 2 and 4, the pair of discharges on both sides are not uniform, and in extreme cases, only one of the discharges occurs. Since this may not occur, it may cause erroneous discharge such as crosstalk and erroneous display.

Also, an insulating layer 3 is interposed between the lower electrode X electrode 2 and the upper electrode Y electrode 4, but the insulating layer 3 is integrated with the dielectric layer 7. In addition, the thickness of the dielectric layer 7 is thicker on the lower electrode X electrode 2 than on the upper electrode Y electrode 4, which is also the X and Y electrodes. This is one of the causes of the difference in characteristics 2 and 4 and causes a problem in electrode driving. Further, when the insulating layer 3 is made thin, the capacitance between the two electrodes increases, and the withstand voltage between the electrodes also decreases, which also poses a problem in electrode driving.

Furthermore, in the case of the transmissive phosphor layer, the phosphor layer is deposited only on the front glass substrate, so that the phosphor layer is deposited on the side and bottom surfaces of the partition as in the above-mentioned three-electrode surface discharge type PDP. When compared with the case where the phosphor layer was formed, the amount of the phosphor layer was limited, and there was a limit in improving the luminance. In addition, since the phosphor is usually white, the contrast is low.

On the other hand, there is also a problem with the three-electrode surface discharge type PDP. In this type of PDP, since the phosphor layer is formed on the rear glass substrate side, the emission color of the phosphor layer is mixed with the emission color of the discharge gas, and the color purity is reduced. .

In addition, the three-electrode surface-discharge PDP has a three-electrode configuration in which one electrode, that is, a sustain electrode, is added to the two electrodes originally required for an XY matrix-type PDP. However, the cost is high and there is a problem in manufacturing. Furthermore, since the discharge electrode is on the front glass substrate side, the electrode blocks light emitted from the phosphor layer. In order to avoid this, a transparent electrode or a very thin electrode, or a highly transparent dielectric layer or a protective layer must be formed, and the production becomes troublesome and leads to an increase in cost. In view of the above, the present invention provides a flat-panel display which has a simple structure, is easy to manufacture, is inexpensive, has stable discharge operation, hardly generates crosstalk between adjacent display cells, and can increase the resolution. They are trying to propose a device.

In addition, the present invention has a simple structure, is easy to manufacture, is inexpensive, has a stable discharge operation, hardly generates crosstalk between adjacent display cells, can increase the resolution, and has high brightness. It proposes a flat-panel display device that can perform color display.

Furthermore, the present invention has a simple structure, is easy to manufacture, is inexpensive, has a stable discharge operation, is unlikely to cause crosstalk between adjacent display cells, and has high brightness, high contrast and high resolution. This is to propose a flat-panel display device that can perform color display. Disclosure of the invention

First, with reference mainly to FIG. 4, the structure of the flat display device will be described together with its manufacturing method. On the back-side glass substrate 1, a first electrode, for example, an X electrode 2 composed of a plurality of strip-shaped electrodes having a fixed width and arranged in parallel with each other at a fixed interval is formed by deposition. this

The X electrode 2 is formed by, for example, screen printing a conductive paste of silver, nickel, or the like on the rear glass substrate 1 and firing it. The X electrode 2 may be formed by a thin film method such as a photolithography method or a vacuum evaporation method, or another method.

Next, an insulating layer (composed of a material having a relatively low dielectric constant, such as a low-melting glass) 3 which covers the X electrode 2 and insulates it from the Y electrode 4 to be formed later is formed. And over the rear glass substrate 1 and the X electrode 2. The insulating layer 3 is formed, for example, by screen-printing a low-melting-point glass space on the rear-side glass substrate 1 and the X-electrode 2, and baking it.

The thickness of the insulating layer 3 is usually about 0.02 to 0.03 mm, if only the insulation between the XY electrodes 2 and 4 is required, a withstand voltage of about 200 V is sufficient. It should be enough.

However, the thickness of the insulating layer 3 is set to about 0.04 so that the insulating layer 3 does not function as a dielectric layer covering the discharge electrode of the AC PDP. mm or more, for example, about 0.04 to about 0.08 mm. Of course, to satisfy the condition of the dielectric layer that does not cause discharge, If a lower material is used, the thickness of the insulating layer 3 can be made smaller.

Referring to FIG. 7, the upper Y electrode 4 is arranged so as to be apparently separated from the lower X electrode 2, but the insulating layer 3 and the dielectric layer covering the discharge electrode of the AC-type PDP are different from each other. If such a function is not performed, no discharge occurs on the right side of the Y electrode 4.

Referring mainly to FIG. 7 and also to FIGS. 4, 5, and 6, the island-shaped electrode and the conductor connecting between the island-shaped electrode and the X electrode 2 as a lower layer electrode are described. explain. A through hole 5 is formed in the insulating layer 3 in the vicinity of the Y electrode 4, and a columnar body obtained by sintering a conductive paste, for example, a columnar (for example, a square quadrangular prism, a rectangular quadrangular prism, etc.) conductor 26 is penetrated therethrough. It is formed in the through hole 5. Then, an island-shaped electrode (small electrode) 6 is formed on the insulating layer 3 so as to be connected to the conductor 26. This island electrode 6 is formed simultaneously with the Y electrode 4. Thus, island electrode 6 is electrically connected to X electrode 2 through conductor 26.

The island-shaped electrode 6 may be formed by printing and firing a conductive paste such as silver or nigel, as in the case of the X electrode 2 and the Y electrode 6.

Thus, the Y electrode 4 and the island electrode 6 are arranged on the insulating layer 3 in parallel. The surfaces of the Y electrode 4 and the island electrode 6 are covered with a dielectric layer 7.

Since the dielectric layer 7 accumulates wall charges similarly to that of a normal AC PDP, the dielectric layer 7 is thinner than the insulating layer 3 so as to increase the capacitance, for example, from 0.01 mm to 0.02 mm. Select the degree. Although not shown, a protective layer of a material having a high secondary electron emission ratio, such as magnesium oxide, and having a high resistance to ion bombardment is usually formed on the surface of the dielectric layer 7 by coating. . The discharge is excited from the electric field shape before the discharge as shown by the discharge path 20.

Next, referring to FIGS. 4 and 5, the structure of the front-side glass substrate 11 will be described. Will be described. A plurality of grooves 8 are formed in the front glass substrate 11 so as to correspond to the X electrodes (first electrodes) 2 on the rear glass substrate 1.

Instead of each groove 8, a row of depressions may be used. In that case, a plurality of rows of depressions correspond to the plurality of grooves 8. The shape of the depression is, for example, a dome shape.

The groove 8 can be easily formed by a method such as a chemical etching method or a sand-plast method for the front glass substrate 11.

On the inner surface of the plurality of grooves 8 of the front-side glass substrate 11, red, green, and blue light-emitting phosphor layers 9 are sequentially formed in a cyclic manner. The formation of the phosphor layer 9 in the groove 8 is performed, for example, by applying the phosphor by a screen printing method.

In the case of depressions, red, green and blue light-emitting phosphor layers 9 are sequentially formed on the inner surfaces of the depressions in a plurality of rows of the front glass substrate 11 cyclically for each row.

The depth of the groove 8 is preferably about 0.1 to 0.2 mm. The width of the groove 8 is about 0.15 to 0.5 mm in a normal PDP. Since the thickness of the phosphor layer 9 is about 0.01 mm, the groove 8 is not filled with the phosphor. In addition, regardless of whether the groove 8 is formed by the chemical etching method or the sand plating method, the cross-sectional shape is advantageous for improving the luminance and the viewing angle of the phosphor layer 9 as shown in FIG. In general, it is generally inverted U-shaped.

The red, green, and blue light-emitting phosphor layers 9, which are primary colors, respectively, are directly formed on the inner surface of the groove 8 of the front glass substrate 11 or, as shown in FIGS. The primary colors red, green, and blue color filters 10 are formed on the inner surface of the color filter 8, and then the corresponding primary colors red, green, and blue color filters 10 are formed on the red, green, and blue color filters 10, respectively. The green and blue light emitting phosphor layers 9 are formed. The color filter 10 is generally formed by adding a pigment to low-melting glass and coloring each primary color, and can be easily formed by screen printing or the like.

Align the front glass substrate 11 so as to cover the rear glass substrate 1, vacuum seal both glass substrates 1, 1 1 with glass frit, etc., and then space between the two glass substrates 1, 11 A gas mixture suitable for discharge, such as neon, argon, or xenon, is filled in at about 0.5 atm, and the flat panel display is completed.

In the example of the flat panel display described with reference to Figs. 4 to 7, the X electrode (first electrode) 2, the insulating layer 3, the Y electrode (second electrode) 4, the island electrode 6, the dielectric layer 7 and the conductor 26 are provided, and the front glass substrate 11 is provided with the groove 8 (may be a row of depressions), the phosphor layer 9 and the color filter 10. On the glass substrate 11 side, an X electrode (first electrode) 2, an insulating layer 3, a Y electrode (second electrode) 4, an island electrode 6, a dielectric layer 7, and a conductor 26 are provided. The glass substrate 1 may be provided with a groove 8 (a row of depressions may be provided), a phosphor layer 9 and a color filter 10.

In the latter case, the members such as electrodes provided on the front glass substrate 11 may be made transparent, but if they are not made transparent, the transparency of each member on the front glass substrate 11 becomes a problem. In this case, the position of the X electrode 2 is made to correspond to the partition wall between the grooves 8 formed on the rear glass substrate 1 and the through electrode for connecting the island electrode 6 and the X electrode 2 is formed. A protruding portion that protrudes to the position of the hole 21 may be provided on the X electrode 2.

Next, another example of the flat display device (PDP) according to the embodiment of the present invention will be described with reference to a partial cross-sectional view of the flat display device in FIG. In the example shown in FIG. 8, a hole 24 penetrating the island-shaped electrode 6 and the conductor 26 is formed, and a dielectric layer 7 is also formed in the hole 24. In this case, a so-called hollow electrode 21 is formed. The island-shaped electrode 6 and the X electrode 2 as the lower layer electrode are not completely filled with the conductive hole 24 electrically connected through the conductor 26 and the conductive paste and the dielectric layer 7. The Y-shaped electrode 4 and the island-shaped electrode are indented, and the diameter of the indentation is suitable for generating the holo effect (the diameter is about 0.05 mm in a normal PDP). In the AC discharge between the electrodes 6, a hollow effect occurs when the island-shaped electrode 6 operates as a force source, and a decrease in the discharge voltage and an increase in the luminous efficiency are observed. One electrode 21 becomes a hollow cathode.

The dielectric layer 7 only needs to be coated on the entire inner peripheral surface of the hole 24, and the dielectric layer 7 does not necessarily have to be coated on the X electrode 2 at the lower end of the hole 24. . That is, it is possible that the hollow electrode 21 operates as a DC electrode while the island-shaped electrode 6 operates as an AC electrode.

In the example of the flat-panel display device described with reference to FIGS. 4 to 7, when adjacent display cells are extremely close to each other, the island-shaped electrode 6 and two second electrodes located on both sides of the island-shaped electrode 6 are provided. (Y electrode) So-called crosstalk, in which a discharge occurs not only between the electrodes closer to each other but also between the other electrodes on the opposite side, that is, erroneous discharge is likely to occur, particularly in a high-resolution PDP. The operating voltage range will be narrowed.

Therefore, with reference to FIGS. 9 to 12, still another example of the flat display device according to the embodiment of the present invention in which the disadvantages of the example of the flat display device described with reference to FIGS. Will be described. FIG. 9 is a perspective partial view of still another example of the flat display device, FIG. 10 is a partial sectional view, FIG. 11 is a plan view showing an electrode arrangement, and FIG. 12 is an exploded perspective partial view.

First, with reference to FIG. 9 and FIG. 10, the structure of the flat display device will be described together with its manufacturing method. A plurality of strip-shaped electrodes of a fixed width arranged on the rear-side glass substrate 1 at regular intervals and parallel to each other A first electrode, for example, an X electrode 2 is formed by deposition. The X electrode 2 is formed by, for example, printing a conductive paste of silver, nickel, or the like on the rear glass substrate 1 by screen printing and firing the conductive paste. The X electrode 2 may be formed by a photolithography method, a thin film method such as vacuum deposition, or another method.

Next, an insulating layer 3 that covers the X electrode 2 and insulates from the Y electrode 4 to be formed later is formed on the rear glass substrate 1 and the X electrode 2. The insulating layer 3 is formed by, for example, screen-printing a low-melting-point glass base over the rear-side glass substrate 1 and the X-electrode 2 and firing the screen.

If only the insulation between the XY electrodes 2 and 4 is to be performed, a withstand voltage of about 200 V is sufficient, and the thickness of the insulating layer 3 is usually about 0.02 to 0.03 mm. It should be enough.

However, here, the thickness of the insulating layer 3 is set to about 0.04 so that the insulating layer 3 does not function as a dielectric layer covering the discharge electrode of the AC PDP. mm or more, for example, about 0.04 to about 0.08 mm. Of course, if the insulating layer 3 is made of a material having an extremely low dielectric constant so as to satisfy the condition of the dielectric layer that does not cause discharge, the thickness of the insulating layer 3 can be made smaller. it can.

With reference mainly to FIG. 10 and also to FIG. 9, a description will be given of an island electrode and a conductor that connects the island electrode and the X electrode 2 as a lower layer electrode. A through hole 5 is formed in the insulating layer 3 in the vicinity of the Y electrode 4, and a columnar, for example, columnar conductor 26, which is obtained by firing a conductive paste, is formed in the through hole 5. The size and shape of the through-hole 5 are selected according to the electrode width and the pixel pitch, and may be a square or a rectangle other than a circle.

Then, on the insulating layer 3 so as to be connected on the conductor 26 An island-shaped electrode 6 is formed. This island electrode 6 is formed simultaneously with the Y electrode 4. Thus, the island electrode 6 is electrically connected to the X electrode 2 through the conductor 26. The island-shaped electrode 6 may be formed by printing and firing a conductive paste such as silver or Nigger, similarly to the X electrode 2 and the Y electrode 6.

Thus, the Y electrode 4 and the island electrode 6 are arranged in parallel on the insulating layer 3, but in this example, the Y electrode 4 is located at a symmetrical position on the left and right sides of the island electrode 6, respectively. It is made to be arranged. The surfaces of the Y electrode 4 and the island electrode 6 are covered with a dielectric layer 7. Since the dielectric layer 7 accumulates wall charges in the same manner as that of a normal AC PDP, the dielectric layer 7 is thinner than the insulating layer 3 so as to increase the capacitance, for example, 0.01 mm to 0.02 mm. Select the degree. Although not shown, the surface of the dielectric layer 7 is usually further coated with a material having a high secondary electron emission ratio, such as magnesium oxide, and having a high resistance to ion bombardment.

As is apparent from FIG. 10, electric fields 22 and 23 of two independent display cells 1 and 2 are formed between the island electrode 6 and the Y electrodes 4 on both sides thereof. Discharges occur independently between the left half of the island electrode 6 and the left Y electrode 4 and between the right half of the island electrode 6 and the right Y electrode 4.

Figure 11 shows the X electrode 2 (XI, X2, X3,), the Y electrode 4 (Yl, Υ2, Υ3,), and the island electrode 6 (S

1 1 2, S 2 1 2, S 3 1 2,, S I 3 4, S 2 3

The following shows an example of the arrangement relationship of 4, S334,).

The Y electrodes Y 1 and Y 2 are arranged on both sides of the island electrodes S 1 1 2, 2 1 2 and 3 1 2, respectively, on both sides of the island electrodes S 1 3 4, 2 3 4 and 3 3 4. , Y electrode Y3, Υ4 are arranged. In other words, the island electrodes S 1 1 2, 2 1 2, 3 1 2, Further, two Y electrodes Y 2, 3 are arranged between the island-shaped electrodes S 134, 230, and 334.

Also, on the X electrode X 1, there are island electrodes S 1 1 2, 1 3 4,

Are arranged on X electrode X 2, island electrodes S 2 1 2, 2 3 4, are arranged on X electrode X 3, island electrodes S 3 1 2,

3 3 4 are arranged.

Further, the X electrodes XI, X2, X3 face each other at a predetermined interval, and the Y electrodes Yl, Υ2, Υ3,

And orthogonal.

Next, the structure of the front glass substrate 11 will be described with reference to FIG. A plurality of grooves 8 (may be a plurality of rows of depressions) are formed in the front glass substrate 11 so as to correspond to the X electrodes (first electrodes) 2 on the rear glass substrate 1. .

The groove 8 can be easily formed by a method such as a chemical etching method or a sand blast method for the front glass substrate 11.

The depth of the groove 8 is preferably about 0.1 to 0.2 mm. The width of the groove 8 is about 0.15 to 0.5 mm in a normal PDP. Since the thickness of the phosphor layer 9 is about 0.01 mm, the groove 8 is not filled with the phosphor. In addition, regardless of whether the groove 8 is formed by the chemical etching method or the sand-plast method, its cross-sectional shape is substantially inverted U-shaped, which is advantageous for improving the luminance and the viewing angle of the phosphor layer 9. In general,

The red, green, and blue light-emitting phosphor layers 9, which are primary colors, respectively, are directly formed on the inner surface of the groove 8 of the front glass substrate 11, or The primary colors red, green and blue power filters 10 are formed on the inner surface, and then the corresponding primary colors red, green and blue power filters 10, respectively, are formed on the red, green and blue power filters 10 respectively. The green and blue light emitting phosphor layers 9 are formed.

The color filter 10 is generally formed by adding a pigment to low-melting glass and coloring each primary color, and can be easily formed by screen printing or the like.

The front glass substrate 11 is fitted so as to cover the rear glass substrate 1, and the two glass substrates 1 and 11 are vacuum-sealed with glass frit etc., and then the space between the two glass substrates 1 and 11 A gas mixture suitable for discharge, such as neon, argon, or xenon, is filled in at about 0.5 atm, and the flat panel display is completed.

Next, a modification of the flat display device shown in FIGS. 9 to 12 will be described with reference to FIG. When the area of the island-shaped electrode 6 is relatively small as in the case of a high-resolution PDP, in order to clearly separate the adjacent discharge cells, the area on the dielectric layer 7 corresponding to the approximate center of the island-shaped electrode 6 is reduced. For example, 0.02 to 0, which extend in the direction in which the X electrode 2 extends, on the dielectric layer 7 corresponding to the middle of the first and second X electrodes 4 on the left and right sides of the island electrode 6, respectively. If a low-layer partition wall (approximately 3 mm in height, made of an insulator having a low dielectric constant such as low-melting glass) 29 is formed, it is possible to form an island-shaped electrode 6. Can be divided, the operating range can be expanded, and crosstalk between adjacent display cells can be reduced.

Further, as shown in FIG. 14, by providing a grid-like partition wall 29 individually surrounding each display cell on the dielectric layer 7, it is also possible to reduce crosstalk between adjacent display cells.

By the way, usually, the screen of all display devices is composed of a light-emitting part and a non-light-emitting part, and the contrast ratio is increased by making the non-light-emitting part black. I am trying to.

However, the front-side glass substrate 11 in the above-described example of the flat panel display (PDP) has a problem in contrast in that the non-light-emitting portion is small compared to the area of the phosphor layer that is the light-emitting surface. Was.

In all types of PDPs, speeding up and stabilizing so-called address discharge is very important for increasing the resolution of the screen. In PDPs, supplying charged particles and metastable atoms that trigger discharge, i.e., so-called priming, to discharge cells is an effective measure to reduce discharge delay time and stabilize operation. Is well known.

However, in the conventional PDP, an auxiliary discharge mechanism having an effective and simple structure has not been realized due to problems such as emission of the auxiliary discharge lowering the contrast of the screen.

The structure of the glass substrate which has solved the above-mentioned problems will be described with reference to FIG. 15 showing a perspective view. Reference numeral 11 denotes a glass substrate (here, a front glass substrate, but may be a rear glass substrate). The front glass substrate 11 is provided with a plurality of grooves 8 (a plurality of rows of recesses) of a concave curved surface having the same width, the same depth, and the same shape (for example, a U-shaped cross section) parallel to each other.

The groove 8 is formed on the front glass substrate 11 by a method such as a sand blast method or a chemical etching method. 8 BR indicates a partition wall between adjacent grooves 8.

A black layer (eg, a black glass layer) BL, a red light-emitting phosphor layer 9 R, a green light-emitting phosphor layer 9 G, and a blue The light emitting phosphor layers 9B are sequentially formed in a cyclic manner, for example, by coating.

Since three adjacent grooves 8 coated with red, green and blue light emitting phosphor layers 9R, 9G, and 9B form one color pixel, this force The groove 8 having the black layer BL applied to separate the color pixels improves the contrast ratio of a color image composed of a large number of color pixels.

The light emitted from the phosphor layers 9 R, 9 G, and 9 B in each of the plurality of grooves 8 may be diffused to cause a slight color mixture.However, the presence of the concave grooves 8 on which the black layer is applied is This has the effect of not only improving the contrast ratio but also slowing down color mixing.

In addition, between each of the grooves 8 on which the adjacent color phosphor layers 9 R, 9 G, and 9 B are provided, or between each of the two grooves 8, the grooves 8 on which the black layer BL is provided. If the color image is arranged, the contrast ratio of the color image is further improved.

In this example, the width of the groove 8 applied to the black layer BL is set to be the same as the width of the groove 8 applied to the phosphor layers 9 R, 9 G, and 9 B of each color. You don't have to. That is, the width of the groove 8 provided on the black layer BL may be wider or narrower than the width of the groove 8 provided on each color phosphor layer 9R, 9G, 9B.

Further, the width of the groove 8 attached to each color phosphor layer 9R, 9G, 9B is the same in this example, but does not necessarily have to be the same. The width of the groove 8 on which the phosphor layers 9R, 9G, and 9B are attached may be changed for each emission color to adjust the color balance.

With reference to the exploded perspective partial view of FIG. 16, the structure of the flat panel display device to which the front glass substrate 11 of FIG. 15 is applied will be described. On the rear glass substrate 1, a first electrode, for example, an X electrode 2, which is composed of a plurality of strip-shaped electrodes having a fixed width and arranged in parallel with each other at a fixed interval, is formed. The X electrode 2 is formed by, for example, printing a conductive paste of silver, nickel, or the like on the rear glass substrate 1 by screen printing and firing the conductive paste. The X electrode 2 may be formed by a photolithography method, a thin film method such as vacuum deposition, or another method. Next, an insulating layer 3 that covers the X electrode 2 and insulates from the Y electrode 4 to be formed later is formed on the rear glass substrate 1 and the X electrode 2. The insulating layer 3 is formed, for example, by screen-printing a low-melting glass base over the rear glass substrate 1 and the X electrodes 2 and firing the screen.

However, here, the thickness of the insulating layer 3 is set to about 0.04 so that the insulating layer 3 does not function as a dielectric layer covering the discharge electrode of the AC PDP. mm or more, for example, about 0.04 to about 0.08 mm. Of course, if a material having an extremely low dielectric constant is used as the insulating layer 3 so as to satisfy the condition of the dielectric layer that does not cause discharge, the thickness of the insulating layer 3 can be made smaller than this. .

In the example of FIG. 16, the front glass substrate 11 of FIG. 15 is applied to the front glass substrate 11 of the flat panel display device. The black layer BL, the red phosphor layer 9R, the green phosphor layer 9G and the blue phosphor layer 9B are sequentially circulated in the plurality of grooves 8 (multiple rows of depressions may be formed). It may be formed so as to adhere to the surface.

In this case, the X-electrode 2, the Y-electrode 4, the island-like electrode 6, and the like are arranged on the front glass substrate 11 side to form a reflective phosphor screen type two-electrode surface discharge PDP.

Next, a modification of the flat display device of FIG. 17 will be described. In FIG. 16, the island-shaped electrode 6 for discharge corresponding to the groove 8 (or a row of depressions) on which the black layer BL is attached is not formed, but this portion is supplemented as shown in FIG. 17. The discharge island electrode 27 may be formed. This supplement The auxiliary discharge island electrode 27 is not limited to the AC type, and may be a so-called DC type electrode whose surface is not covered with a dielectric layer. Since the light emitted by the auxiliary discharge island-shaped electrodes 27 does not go out of the groove 8 on which the black layer BL is attached, there is no danger of lowering the contrast of the screen. Since the auxiliary discharge by the auxiliary discharge island electrode 27 is always lit regardless of the image signal, effective priming can always be supplied to the pixel adjacent to the auxiliary discharge cell.
