  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an exploded perspective view showing a configuration of a panel device including a spacer according to an embodiment of the present invention.

  In FIG. 1, a flat electron beam excitation display panel 100 (image display device) as a panel device including a spacer according to an embodiment of the present invention has an image forming member 5 provided on the inner surface and a front plate (front panel). A glass substrate 1 to be formed and a glass substrate 2 on which a later-described electron-emitting device 25 group is mounted to form a back plate (rear panel) are provided. The image forming member 5 includes a phosphor that emits light when irradiated with an electron beam from the electron-emitting device 25.

  The display panel 100 is a large display panel having a screen size of, for example, 50.8 cm (20 inches). The screen size may be 50.8 cm (20 inches) to 254 cm (100 inches).

The glass substrates 1 and 2 are made of, for example, soda lime glass, and the linear expansion coefficient of the glass is between 88 × 10 ^{−7 and} 92 × 10 ⁻⁷ K ⁻¹ .

As shown in FIG. 2 which is a cross-sectional view taken along the line II-II in FIG. 1, the glass substrates 1 and 2 are arranged to face each other in parallel via a plurality of spacers 4 (FIG. 3) and the support frame 3. Thus, a vacuum vessel is formed which is airtightly bonded via the support frame 3 and forms an airtight and atmospheric pressure resistant structure together with the support frame 3. The vacuum vessel is provided with a hole (not shown) for evacuating the display panel 100 in a vacuum atmosphere of about 1.33 × 10 ⁻³ Pa (about 10 ⁻⁵ torr) or less.

  In addition, the display panel 100 is assembled by arranging the spacers 4 on the glass substrate 2 on which the electron-emitting devices 25 are mounted and arranging and fixing them at a predetermined pitch via a sealing frit (adhesive 8). The glass substrate 1 is bonded to the spacer 4 using a sealing frit, and heat treatment is performed by baking at about 400 to 500 ° C.

The rear panel includes a glass substrate 2, a plurality of element portions 23 made of nickel (Ni) having a thickness of 100 nm (1000 angstroms) arranged in a matrix on the glass substrate 2, and power to the element portions 23. And a plurality of wiring portions 24 made of silver (Ag) having a thickness of 2 μm formed on the glass substrate 2. An electron-emitting device 25 is formed in each element portion 23. The wiring portion 24 generally has a maximum width of 0.30 mm. The wiring pattern of the wiring part 24 is a pattern of parallel lines, and a plurality of electron-emitting devices 25 along these wiring parts 24 are fed simultaneously through a pair of adjacent wiring parts 24. Further, although not shown, a modulation electrode having an electron passage hole with a diameter of 50 μm is disposed 10 μm above the glass substrate 2 via a silica (SiO ₂ ) insulating layer. The electron-emitting device 25 is disposed on the glass substrate 2 at a portion corresponding to a display screen that displays an image of the display panel 100.

  Each of the spacers 4 is fixed to the glass substrate 2 with an adhesive 8 at the lower center of the spacer 4 (FIG. 5), but the lower edge of the spacer 4 is bonded to the glass substrate 2 with an adhesive. It may be fixed. Alternatively, the upper substantially central portion or upper edge portion is fixed to the glass substrate 1 with the adhesive 8 at the end portion, or the upper and lower substantially central portions or edge portions are made of glass with the adhesive 8. You may adhere to each of the board | substrate 1 and the glass substrate 2. FIG.

  Further, the spacer 4 is disposed on the wiring portion 24 in a space between the electron-emitting devices 25 adjacent to each other so that the display panel 100 can perform light emission display. Thereby, the aperture ratio of the display panel 100 can be improved.

  FIG. 3 is a top view of the spacer 4 of FIG.

  As shown in FIGS. 1 to 3, the spacer 4 is long and long in the longitudinal direction of the display panel 100, and its cross-sectional shape is a rectangle whose width is shorter than the height in the cross-section.

  As shown in FIG. 3, the spacer 4 includes a long portion 40, an end portion 41, and an end portion 42, and is formed between the long portion 40 and the end portion 41 and between the long portion 40 and the end portion. Between the portions 41, bent portions are formed by bending, which will be described using a longitudinal sectional view of FIG. 4 described later.

For example, the spacer 4 has a length L ′ shown in FIG. 3 which is a longitudinal dimension of 500 mm and a thickness, that is, a width which is a lateral dimension in the cross section of FIG. 2 is 0.2 mm. The height, which is the vertical dimension in the cross section, is 1.0 mm, the cross-sectional area is 0.2 mm ² , and the aspect ratio representing the value of the ratio of the height to the width in the cross section is 5.

  Further, both end portions 41 and 42 of the spacer 4 form acute angles with respect to the long portion 40 when viewed from the front panel side, such that the predetermined angle θ is less than 90 °, for example, 30 ° and 30 °. The end portions 41 and 42 have lengths L of, for example, 3.0 mm and 3.0 mm, respectively.

  The two bent portions are formed by bending in opposite directions. By bending in directions opposite to each other, the easiness of standing of the spacer 4 can be improved more reliably.

  Further, the bent portion is erected in a space between the glass substrates 1 and 2 at a predetermined portion of the spacer corresponding to a non-display area (hereinafter referred to as “dead space”) where the image of the display panel 100 is not displayed. Thus, the dead space of the display panel 100 can be reduced.

  The spacer 4 is manufactured as follows.

First, glass having a predetermined composition, for example, alkali-free glass is machined or stretched to prepare a base glass having a shape substantially similar to the cross-sectional shape of the spacer 4, that is, the cross-sectional shape is an aspect ratio of 5. To do. The size of the base glass is, for example, a thickness of 2 mm, a height of 10 mm, a length of 2000 mm, and a cross-sectional area of 20 mm ² that is 100 times the cross-sectional area of the spacer 4 to be manufactured.

In addition, the size of the base glass is the thickness, that is, the width that is a transverse dimension in the transverse section is 0.2 to 60 mm, the height that is the longitudinal dimension in the transverse section is 1 to 300 mm, and the longitudinal dimension thereof. The length is preferably in the range of 200 to 4000 mm, so that the cross-sectional area of the base glass is 100 to 7000 times the cross-sectional area of the glass spacer 4 to be obtained, ie 1.8 to 10500 mm ^2. It is preferable to be determined within the range.

  In addition, as a material of the base glass, any composition such as low alkali glass or soda lime glass may be used instead of the alkali-free glass, but the spacer 4 manufactured from the base glass is used for the display panel 100. Therefore, as the material of the base glass, it is preferable to use low alkali glass or non-alkali glass with a low content of alkali metal that degrades the electron beam source used for the electron-emitting device 25.

  Next, a stretched glass is produced by subjecting the base glass to a stretching process using a redraw method, which will be described later, so that the size of the cross section of the spacer becomes the above-described desired value.

In the redraw method, the base glass is stretched while locally heated in an electric furnace. The base glass has a viscosity of 10 ⁴ to 10 ⁸ Pa · s (Pascal second) (10 ⁵ to 10 ⁹ P (poise)), preferably 10 ⁶ to 10 ⁸ Pa · s (10 ⁷ to 10 ⁹ P). ) To a temperature that falls within the range of The base glass thus heated is slowly conveyed from one direction to the electric furnace at a predetermined speed and pulled from the other direction at a speed several to several thousand times the predetermined speed. Is stretched in a state in which the cross-sectional shape is maintained, and a stretched glass having a cross-sectional shape similar to that of the base glass, that is, an aspect ratio of 5, is produced.

In the redraw method, when the viscosity is lower than 10 ⁴ Pa · s (10 ⁵ P), the cross-sectional shape before the heating of the base glass is not maintained and the cross-sectional shape is circular. Alternatively, the desired cross-sectional shape of the spacer 4 can be obtained by approaching an ellipse, while the base glass is broken during the drawing process when the viscosity is higher than 10 ⁸ Pa · s (10 ⁹ P). It becomes easy.

  Subsequently, the stretched glass is cut in accordance with the size of the display panel 100 so that the manufactured stretched glass has a desired length, and a long spacer 4 ′ described later in FIG. 4 is obtained.

  Since the long spacer 4 ′ has a large aspect ratio and is difficult to stand as it is, the long spacer 4 ′ is further provided between the glass substrates 1 and 2 at a portion corresponding to the dead space. A bending process, which will be described later, is performed so as to form a bent portion between the position where the space is erected, that is, between the both end portions 41 and 42 and the long portion 40.

  FIG. 4 is a vertical cross-sectional view used for explaining a bending process performed to form the spacer 4 of FIG.

  As shown in FIG. 4, in the bending process, first, one side of a portion where a bent portion is to be formed in the long spacer 4 ′, that is, between both end portions 41, 42 of the spacer 4 and the long portion 40. The long spacer 4 ′ is placed so that the corresponding position faces the peripheral edge 301 of the stage 300 and the corner of the stepped portion 301 fixed on the stage 300. Next, the long spacer 4 ′ placed on the stage 300 is heated and softened by a heating device such as an electric furnace. As a result, the softened long spacer 4 ′ is bent in the vertical direction by gravity around the part facing the peripheral edge 301 or the corner of the step 302. In this way, the spacer 4 having a bent portion formed by bending in opposite directions as viewed from the front panel side between the both end portions 41, 42 and the long portion 40 is manufactured.

  Instead of the electric furnace, a burner may be used as a heating device. In this case, when both ends of the long spacer 4 ′ are locally heated, the bent long spacer 4 ′ is used as the bent spacer 4 ′. An annealing treatment is preferably performed.

  Hereinafter, the display panel 100 is manufactured as follows.

  As described above, the spacer 4 in which the bent portions defining the end portions 41 and 42 are formed is arranged between the glass substrates 1 and 2 in the portion corresponding to the dead space. For example, it stands on the glass substrate 2 and is fixed by an adhesive 8 such as a sealing glass frit described later. Since the spacer 4 having the bent portion is easily erected, the arrangement of the spacer 4 can be improved. In addition, it is possible to eliminate the need to previously fix a spacer support member or the like for arranging the spacer 4 on the glass substrate 2 to the glass substrate 2. Furthermore, the spacer 4 can be accurately positioned with respect to the space between the electron-emitting devices 25 adjacent to each other, so that even when a positional deviation occurs, it can be easily corrected. Therefore, the assembly of the display panel 100 can be facilitated and the manufacturing cost of the display panel 100 can be reduced.

  When the adhesive 8 is a glass frit for sealing, the glass substrate 2 on which the spacer 4 is erected is heated to 400 to 500 ° C. which is the melting point thereof. By this heating, the spacer 4 expands relative to the glass substrate 2 and stress is generated by the expansion. Therefore, if the glass frit for sealing is disposed over the entire lower surface of the spacer 4, there is a possibility that the spacer 4 will be displaced or damaged, so in order to improve the yield, It is preferable that the spacer 4 is locally disposed on the lower surface of the spacer 4. Specifically, the glass frit for sealing is attached to at least one end portion of the spacer 4, for example, in a substantially central portion below the end portion 41 as shown in FIG. 5 which is a bottom view of the spacer 4 in FIG. More preferably, the lower edge of the end portion 41 is fixed to the rear panel. The end portion 42 may be used instead of the end portion 41.

  Subsequently, the glass substrate 2 to which the plurality of spacers 4 are fixed by the sealing glass frit and the glass substrate 1 are joined together with the support frame 3 so as to form a container, and the formed container is an exhaust pump or the like. And the inside is sealed in a vacuum state. In this way, the display panel 100 is manufactured.

  Hereinafter, modified examples of the spacer 4 of FIG. 3 will be described.

  Note that the size of the spacer 4 in FIG. 3 is not limited to that described above, and is determined as follows.

  The length L ′, which is the longitudinal dimension of the spacer 4, is determined depending on the size of the display panel 100, the screen size of the display panel 100, and the manufacturing method thereof, and is generally in the range of 30 to 2540 mm.

  The thickness of the spacer 4 is preferably in the range of 0.03 to 0.30 mm. Since the display panel 100 cannot emit and display the portion where the spacer 4 is in contact with the front panel and the rear panel, it is preferable that the spacer 4 is thin. If the thickness of the spacer 4 is less than 0.03 mm, it is too thin and the absolute strength of the spacer 4 is insufficient, making it difficult to handle. Moreover, the spacer 4 will exceed the width | variety of the wiring part 24, if the thickness of the spacer 4 exceeds 0.30 mm.

  The height of the spacer 4 should be in the range of 0.6 to 5.0 mm, preferably 1 to 5 mm. In the display panel 100, a high acceleration voltage (accelrating voltage) of 5000 to 6000 volts is generally used in order to increase the utilization efficiency of the phosphors. This is because it is difficult to ensure the value of 5 mm, and if it exceeds 5 mm, the electron beam emitted from the electron beam source (electron-emitting device 25) spreads too far and emits light to the adjacent pixel (phosphor).

  Moreover, the aspect ratio in the cross section of the said spacer is determined in the range of 2-167, and exists in the range of 4-50 normally.

  The value of the predetermined angle θ may be in the range of 5 to 175 ° when viewed from the front panel side. When the predetermined angle θ is an acute angle of less than 90 °, the easiness of standing of the spacer 4 can be easily improved, and the sharper the angle, the less the spacer 4 is likely to break from the bent portion. Can do. In addition, when the predetermined angle θ is an obtuse angle of 90 ° or more, the easiness of standing the spacer 4 can be improved more reliably as the obtuse angle is increased. Moreover, the dead space can be further narrowed as the value of the angle θ of the end portions 41 and 42 is closer to 90 °. Further, when the value of the predetermined angle θ is in the range of 5 to 45 °, the space between the spacers 4 adjacent to each other can be widened, and the ease of evacuation can be improved.

  The lengths L of the two end portions 41 and 42 corresponding to the longitudinal direction of the long portion 40 are preferably not less than the size indicating the height in the cross section of the spacer 4. Thereby, the easiness of standing of the spacer 4 can be improved reliably, and when the width of the dead space is constant, the portion of the spacer 4 standing corresponding to the dead space can be improved. Since the length is longer than that of the spacer not provided with the end portions 41 and 42 defined by the bent portion, the space between the glass substrates 1 and 2 corresponding to the dead space is effectively utilized, The function as an atmospheric pressure support member can be improved.

  The angle θ and the length L of the end portions 41 and 42 are the length that is the longitudinal dimension of the long portion 40, the ease of cracking of the spacer 4, the size of the dead space, and the ease of vacuuming. It is preferable to determine in consideration of the above. Therefore, the angle θ and the length L of the end portion 41 and the angle θ and the length L of the end portion 42 may be the same value or different values.

  Therefore, the following modifications of the spacer 4 can be given.

  FIGS. 6A to 6E are top views of modified examples of the spacer 4 of FIG.

  The spacer 4 shown in FIG. 6A has two end portions defined by bent portions formed by bending so that the angle θ is an obtuse angle of 90 ° or more, for example, 150 ° and 150 °. 41, 42. Thereby, the easiness of standing of the spacer 4 can be improved reliably.

  The spacer 4 shown in FIG. 6B has two end portions 41 and 42 which are defined by a bent portion formed by bending in the same direction. Thereby, for example, the spacer 4 closest to the support frame 3 shown in FIG. 1 can be made such that its two end portions 41 and 42 do not face the support frame 3, and the arrangement of the spacer 4 in the dead space Can be improved. Such a bent portion can be easily formed by using the two peripheral edge portions 301 and 301 of the stage 300 or fixing the two step portions 302 and 302 on the stage 300 in the bending process. Can do.

  The spacer 4 shown in FIG. 6C or FIG. 6D has two predetermined angles θ and a predetermined curvature with respect to the long portion 40 instead of the two end portions 41 and 42. It has edge part 41 'and 42'. Thereby, generation | occurrence | production of a damage can be suppressed more reliably than the spacer which has the edge parts 41 and 42. FIG. Moreover, the ease of evacuation can be improved. In addition, the bending part which prescribes | regulates edge part 41 'and 42' as shown in FIG.6 (c) shape | molds the two peripheral edge parts 301 of the stage 300 so that it may become a predetermined curvature in bending ( (Not shown) can be easily formed by bending the long spacer 4 ′, and the bent portions defining the end portions 41 ′ and 42 ′ as shown in FIG. It can be easily formed by using a substantially cylindrical member (not shown) fixed in place of the stepped portion 302 on the top. Moreover, you may use the press method for a bending process.

  The spacer 4 shown in FIG. 6 (e) has one bent portion 41 defined by a bent portion formed by bending only between one end portion 41 and the long portion 40. Thereby, the ease of evacuation can be improved.

  In the above embodiment, the plurality of spacers 4 and the support frame 3 define the height of the space between the glass substrates 1 and 2, but only the support frame 3 has the height of the space between the glass substrates 1 and 2. May be defined. In this case, the height of the spacer 4 is lower than the height of the support frame 3, and the spacer 4 functions as a support member for stress generated in the glass substrate 1.

  In the above embodiment, the spacer 4 is fixed to the glass substrate 2, but may be fixed to the glass substrate 1, or may be fixed to both the glass substrates 1 and 2.

  In the said embodiment, although the cross-sectional shape of base material glass, extending | stretching glass, and the spacer 4 was a rectangle, it is not restricted to this, Any shapes, such as a trapezoid, may be sufficient.

  In the above embodiment, the spacer 4 has a bent portion formed by bending the long spacer 4 ′, but instead, it has a portion like a bent portion in advance. The spacer is formed by cutting out from the base glass, re-molding the base glass using a predetermined mold or the like, or connecting a portion corresponding to the end portions 41 and 42 and a portion corresponding to the long portion 40. 4 may be manufactured.

  The spacer according to the present embodiment can be applied not only to the flat electron beam excitation display panel 100 but also to a panel device including at least two panels such as other display panels.
