DETAILED DESCRIPTION OF THE INVENTION As a result of intensive studies to achieve the above object, the present inventor has found that a rectangular flat portion, and a side wall portion which is bent from the flat portion to form a concave shape,
In a glass molded product for a display having a flange portion that is bent outward from the side wall portion, when the thickness of the flat portion of the glass molded product is 2 to 4 mm, the glass molded product can be reduced in weight, When the thickness of the flat portion is relatively thick such as 2.5 to 4 mm, X
By setting the linear absorption coefficient as small as 40 to 110 cm ^-1 to reduce the amount of the composition component that increases the X-ray absorption coefficient, it is possible to suppress an increase in the weight of the glass molded product, and at the same time, the glass molding To the outside of the display when the product is applied to an electron beam excited display
When the flat portion has a relatively small thickness such as 2 to 2.5 mm, the X-ray absorption coefficient of the glass is set to a large value such as 70 to 150 cm ^-1 to suppress the amount of leakage of the line. By increasing the amount of the composition component that increases the X-ray absorption coefficient, it is possible to suppress an increase in the amount of leakage of X-rays to the outside of the display when the glass molded article is applied to an electron beam excited display. I found The present invention has been made based on the above findings.

Hereinafter, the above findings will be specifically described.

The glass molded article according to the present invention has a main composition represented by wt% of 55 to 74% of SiO ₂ and Al ₂ O
_{3 1~15%, B 2 O 3} 0~11%, MgO1~5%, C
aO2-10%, total amount of BaO and SrO 0-29%,
Na ₂ O3~14%, a K ₂ O0~8%, others contain _{AS 2 O 3, SO 3,} SnO 2 or the like as a fining agent.

When the content of SiO ₂ is less than 55% by weight, the chemical durability of the glass deteriorates, and when the content exceeds 74% by weight, the melt formability of the glass becomes difficult. If the content of Al ₂ O ₃ is less than 1% by weight, the chemical durability of the glass deteriorates, and if it exceeds 15% by weight, the viscosity of the glass at the time of melting becomes high and the glass is hardly melted. If B ₂ O ₃ exceeds 11% by weight, it becomes difficult to control the viscosity during glass molding. If the content of MgO is less than 1% by weight, it is difficult to control the viscosity at the time of molding the glass. If the content exceeds 5% by weight, the viscosity of the glass at the time of molding becomes large and it becomes difficult to form a plate. If the content of CaO is less than 2% by weight, it is difficult to control the viscosity at the time of molding the glass. If the content exceeds 10% by weight, the viscosity of the glass at the time of molding becomes large and it becomes difficult to form a plate. When the total amount of BaO and SrO exceeds 29% by weight, the glass tends to be devitrified when the glass is melted. If the content of Na ₂ O is less than 3% by weight, the viscosity of the glass increases, and if it exceeds 14% by weight, the chemical durability of the glass deteriorates. If K ₂ O exceeds 8% by weight, the chemical durability of the glass deteriorates.

Incidentally, the X-ray shielding performance of glass depends on the electron density in the glass, and more specifically, the content of heavy metal oxides such as SrO, BaO or PbO among the glass composition components. In relation to the amount, it increases as the total amount of these components increases. On the other hand, the specific gravity of the glass depends largely on the content of heavy metal oxides such as SrO, BaO or PbO in the glass composition.

Table 1 shows an example showing these relationships.

[0035]

[Table 1]

Table 1 shows various glass materials (samples A to G).
About the relationship between the total amount of BaO and SrO and the specific gravity,
The relationship between the total amount of BaO and SrO and the X-ray absorption coefficient is shown. In Table 1, the X-ray absorption coefficient (cm ^-1 ) of the glass is a value when the electron beam acceleration voltage is 10 keV.
This takes into account that the electron beam acceleration voltage of a flat type electron beam excitation display is usually about several keV to 10 keV.

FIG. 1 is a graph showing the relationship between the total amount of SrO and BaO and the specific gravity of glass, and FIG.
3 is a graph showing the relationship between the total amount of BaO and BaO and the X-ray absorption coefficient of glass.

From FIGS. 1 and 2, it is necessary to increase the total amount of BaO and SrO to increase the X-ray shielding performance (X-ray absorption coefficient (cm ^-1 )) of the glass (FIG. 2). It can be seen that the specific gravity of the glass naturally increases as the total amount of BaO and SrO increases (FIG. 1).

As the glass molded article of the present invention, considering that the electron acceleration voltage (especially FED) of the flat type electron beam excited display is about several kv to 10 kv,
It has been found that there is a preferable embodiment from the viewpoint of reducing the weight of the glass molded product, the safety with respect to the X-ray shielding performance, and the pressure resistance of the glass molded product.

That is, when the display area of the glass molded product is relatively small, the thickness of the glass molded product for securing the pressure resistance of the glass molded product may be small, but it is necessary to maintain the X-ray shielding performance. It is preferable to use glass having a large X-ray absorption coefficient. On the other hand, when the display area of the glass molded product is relatively large, it is necessary to increase the thickness of the glass molded product in order to secure the pressure resistance of the glass molded product, and the X-ray shielding performance of the glass is not so large. It is preferable to use glass having a lower specific gravity.

In the glass molded article of the present invention, it is preferable to use glass having an X-ray absorption coefficient of 40 cm ^-1 or more from the viewpoint of securing X-ray shielding performance required for displaying an image.

In order for the glass molded article to have practical performance in terms of X-ray shielding performance and pressure resistance, when the thickness of the glass molded article is 2.5 to 4 mm, the X-ray absorption coefficient is 40 to 40 mm.
Preferably, the glass molded article is made of 110 cm ^-1 glass. This glass molded product is suitable for displaying relatively small and large images. 2.5-4m thick glass molded product
When the composition is relatively thick such as m, the X-ray absorption coefficient of the glass is set as small as 40 to 110 cm ^-1 to increase the X-ray absorption coefficient (SrO, BaO or PbO).
By reducing the amount of heavy metal oxides), it is possible to suppress an increase in the weight of the glass molded article, and at the same time, to apply X-rays to the outside of the display when the glass molded article is applied to an electron beam excitation type display. Can be suppressed. The thickness of the glass molded product is 2.5-4
When the X-ray absorption coefficient is smaller than 40 cm ^-1 , the X-ray shielding performance of the glass falls below an allowable range. On the other hand, when the X-ray absorption coefficient exceeds 110 cm ^-1 , a composition component that increases the X-ray absorption coefficient The total content of (heavy metal oxides such as SrO, BaO or PbO) increases and the weight of the glass molded product exceeds the allowable range.

On the other hand, the thickness of the glass molded product is 2 to 2.5 m
In the case of m, it is preferable that the glass molded article 10 is made of glass having an X-ray absorption coefficient of 70 to 150 cm ^-1 . This glass molded article is suitable for displaying relatively small and small images. When the thickness of the glass molded product is relatively thin such as 2 to 2.5 mm, the X-ray absorption coefficient of the glass is 70 to 150 c.
By increasing the amount of a composition component (a heavy metal oxide such as SrO, BaO, or PbO) that increases the X-ray absorption coefficient by setting a large value such as m ^−1, the glass molded product is converted to an electron beam excitation type. When applied to a display, an increase in the amount of leakage of X-rays to the outside of the display can be suppressed. When the thickness of the glass molded product is 2 to 2.5 mm, if the X-ray absorption coefficient is smaller than 70 cm ^-1 , the X-ray shielding performance of the glass falls below an allowable range, while the X-ray absorption coefficient becomes 150 cm ^-1 . If it exceeds, the total content of the components (heavy metal oxides such as SrO, BaO or PbO) which increases the X-ray absorption coefficient increases, and the weight of the glass molded product exceeds the allowable range.

In the above findings, the specific gravity and the X-ray absorption coefficient of the glass were evaluated based on the total amount of SrO and BaO. However, SrO or BaO may be replaced with another heavy metal oxide. May be added.

Hereinafter, the structure of a glass molded product for a display according to an embodiment of the present invention will be described with reference to FIG.
FIG. 3 is a cross-sectional view of a molded glass article for a display (hereinafter, referred to as a “front plate”) according to an embodiment of the present invention.

In FIG. 3, the front plate 10 is
A rectangular flat portion 11, a side wall portion (hereinafter, referred to as a “rib”) 12 that is bent and formed to have a concave shape from the flat portion 11, and a flange portion 13 that is bent outward from the rib 12 and continuous. Have. The flat part 11 has a thickness of 2
４4 mm, preferably 2-3 mm. The thickness of the flat portion 11 is preferably 2 mm or more from the viewpoint of securing the pressure resistance of the image display surface in order to make the diagonal length of the image display surface a practical size of about 6 inches. Further, in order to reduce the weight of the apparatus, it is preferable that the thickness be 4 mm or less.

The height of the rib 12 is set to a required height unique to the display, but is preferably 1 to 5 mm. If it exceeds 5 mm, there is a problem that the strength of spacers, which will be described later, which are used at the same time when the display is constructed, is reduced, and it becomes difficult to use the front plate for the display.

The length of the flange portion 13 must be such that the sealing property can be maintained when the front plate is joined to the rear plate by frit glass, laser, or the like, and is 1 to 20 mm. Is preferred. If the length of the flange portion 13 is less than 1 mm, the sealing property cannot be ensured, and if it exceeds 20 mm, the image cannot be displayed up to the peripheral portion of the image display surface.

The specific resistance of the glass is 1.0 × at room temperature from the viewpoint of securing the electrical insulation of the front plate.
It is preferably at least 10 ¹² Ω · cm.

Such a front plate 10 is manufactured by a known heating bending method (for example, Japanese Patent Publication No. 6-4).
No. 9581). That is, after a raw material batch having a composition described below is melted at about 1450 ° C., it is formed into a sheet glass by a known roll-out method, and the sheet glass is polished to a predetermined thickness and cut to a predetermined size. Is placed on the convex mold, the outer periphery is heated to a higher temperature than the central part, deformed by its own weight on the convex mold, and then the sheet glass is pressed with the concave mold to form a flange with a predetermined depth. This is for forming a glass molded product.

Next, the glass molded article with a flange is immersed in a potassium nitrate solution at about 460 ° C. for 3 hours to perform ion exchange from sodium ions to potassium ions in a layer having a depth of about 4 to 30 μm from the surface. . This makes it possible to improve the mechanical strength of the glass molded article by using the surface layer of the glass molded article as a compression strain layer and to make the surface layer a composition that is not easily colored by electron beam irradiation. .

The front plate 10 can be used for an electron beam excited display (FED), a plasma display panel (PDP), and a backlight type liquid crystal display. In the following description, the front plate 1
A case where 0 is used for an electron beam excited display will be described.

As shown in FIG. 4, the front plate 10
Is arranged to face the rear plate 14 with a plurality of spacers 15 interposed therebetween, and the flange portion 13 is sealed to the rear plate 15 by the frit glass 16 to form the pressure-resistant glass container 20. The sealing of the flange portion 13 by the frit glass 16 may be performed by laser light instead of the frit glass 16.

The spacers 15 have the same height as the ribs 12, and maintain the spacing of the flat portions 11 uniformly over the entire surface. Further, the material of the spacer 15 is preferably glass, ceramic, or the like. The spacer is in contact with the surface of the flat portion 11 on which an image is formed. However, in order to ensure uniform display of the screen, a portion where the image is not displayed in the flat portion 11, specifically, a wiring electrode portion or RGB. It is arranged in a portion such as a black matrix at the joint of pixels. Spacer 1
The width of 5 needs to be smaller than these widths, specifically 0.3 mm or less.

Further, the flat portion 1 of the front plate 10
1 is coated with a phosphor 17 and the rear plate 14
Are formed with a plurality of electron-emitting devices 18 on the inner surface thereof.
The inside of the reduced pressure glass container 20 is evacuated to a vacuum via a not-shown ventilation pipe provided in the reduced pressure glass container 20.

According to the present embodiment, since the thickness of the flat portion 11 is 2 to 4 mm, the weight of the front plate 10 can be reduced, and the thickness of the flat portion 11 is 2.5 to 4 mm.
When the glass is relatively thick, as in
An increase in the weight of the front plate 10 can be suppressed by reducing the amount of the composition component that increases the X-ray absorption coefficient by setting it as small as 0 to 110 cm ⁻¹ ,
At the same time, when the front plate 11 is applied to an electron-beam-excited display, the amount of X-ray leakage to the outside of the display can be suppressed, and the thickness of the flat portion 11 can be reduced to 2 to 2.5 mm. When the front plate 10 is very thin, the X-ray absorption coefficient of the glass is set to a large value such as 70 to 150 cm ^-1 to increase the amount of a composition component that increases the X-ray absorption coefficient. In this case, it is possible to suppress an increase in the amount of leakage of X-rays to the outside of the display when the present invention is applied.
