Description

また、本発明の全ての態様に係る封止パネル装置及び全ての態様に係るその製造方法においてシール部材に開口部を設ける場合、開口部はどのような形態にて設けられてもよいが、パネルの周縁部に沿った方向の一部においてシール部材を切り欠くように設けることが最も実用的である。開口部がシール部材を切り欠くように設けられている場合、接着層による蓋部の接着はシール部材のみに対して行われもよいが、シール部材を横断し、第1パネルと第2パネルの双方の側面に対して行われることが一層好ましい。但し、かかる開口部を接着層を用いて蓋部で閉鎖しようとすると、シール部材の構成材料と接着層を構成する低融点金属材料との組合せによっては、これら両者が直接接触することが信頼性の観点から好ましくない場合もある。このような場合には、シール部材と接着層との間に何らかの補助的な部材を介在させることが好ましい。典型的には、第1A及び第2Aの態様に係る封止パネル装置及びその製造方法において、シール部材を構成するフリット・ガラスと接着層を構成する低融点金属材料との直接接触を避けるために、例えば先ず、開口部の周囲にフリット・ガラスから成る補助接着層を用いて貫通孔を有する補助枠体を接着し、この補助枠体の上に接着層を用いて蓋部を接着すればよい。かかる構成においては、第1パネルとシール部材と第2パネルと補助接着層と補助枠体と接着層と蓋部とによって囲まれた空間が真空となる。 Further, when an opening is provided in the seal member in the sealing panel device according to all aspects of the present invention and the manufacturing method thereof according to all aspects, the opening may be provided in any form, but the panel. It is most practical to provide the seal member so as to cut out at a part of the direction along the peripheral edge of the seal member. If the opening is provided so as cutting out the sealing member, adhesion of the lid by adhesive layer may be made to only the sealing member, across the sealing member, the first panel and the second panel It is more preferable that this is done for both aspects of. However, if an attempt is made to close such an opening with a lid using an adhesive layer, it is reliable that both of them come into direct contact depending on the combination of the constituent material of the sealing member and the low melting point metal material constituting the adhesive layer. It may not be preferable from the viewpoint of. In such a case, it is preferable to interpose some auxiliary member between the sealing member and the adhesive layer. Typically, in the sealing panel apparatus according to the first A and the second A and the manufacturing method thereof, in order to avoid direct contact between the frit glass constituting the sealing member and the low melting point metal material constituting the adhesive layer. For example, first, an auxiliary frame having a through hole may be adhered around the opening by using an auxiliary adhesive layer made of frit glass, and a lid portion may be adhered on the auxiliary frame by using an adhesive layer. .. In such a configuration, the space surrounded by the first panel, the sealing member, the second panel, the auxiliary adhesive layer, the auxiliary frame body, the adhesive layer, and the lid portion becomes a vacuum.

図1に、実施の形態1の封止パネル装置の概念的な構成を示す。図1の(A)は模式的断面図、図1の(B)は模式的斜視図である。対角画面寸法14インチを想定して30cm×23cmの矩形形状を有する第1パネル11と第2パネル12とは、周縁部においてシール部材20aによって接着されている。ここで、シール部材20aは厚さ1mmのフリット・ガラスから成る。フリット・ガラスの焼成温度は約450°Cである。第1パネル11は、封止パネル装置としての実用上の機能を果たす中央部の有効領域(28cm×21cm)と、この有効領域機能を支援するために有効領域を額縁状に包囲する無効領域とを有する。尚、図においては、有効領域及び無効領域を明確化するために、有効領域に斜線を付した。また、シール部材にも明確化のため斜線を付した。無効領域には直径約5mmの円形の開口部13が設けられている。開口部13は、接着層30によって第1パネル11に接着された蓋部40により閉鎖されている。接着層30は低融点金属材料から成り、ここではインジウムから成る内径8mm、外径10mmのリングを用いる。インジウムの融点は157°Cである。つまり、この封止パネル装置においては、シール部材20aを構成するフリット・ガラスの焼成温度の方が、接着層30を構成する低融点金属材料よりも高い。蓋部40は、直径15mm、厚さ1mmの円盤状のガラス板である。蓋部40と接着層30と第1パネル11とシール部材20aと第2パネル12とによって囲まれた空間は、真空(VAC)とされている。 FIG. 1 shows a conceptual configuration of the sealing panel device of the first embodiment. FIG. 1A is a schematic cross-sectional view, and FIG. 1B is a schematic perspective view. The first panel 11 and the second panel 12 having a rectangular shape of 30 cm × 23 cm assuming a diagonal screen size of 14 inches are adhered to each other by a sealing member 20a at a peripheral edge portion. Here, the sealing member 20a is made of frit glass having a thickness of 1 mm. The firing temperature of the frit glass is about 450 ° C. The first panel 11 has a central effective region (28 cm × 21 cm) that functions as a sealing panel device, and an invalid region that surrounds the effective region in a frame shape to support the function of the effective region. And have. In the figure, the effective area is shaded in order to clarify the effective area and the invalid area. The seal members are also shaded for clarity. A circular opening 13 having a diameter of about 5 mm is provided in the invalid region. The opening 13 is closed by a lid 40 that is adhered to the first panel 11 by the adhesive layer 30. The adhesive layer 30 is made of a low melting point metal material, and here, a ring made of indium having an inner diameter of 8 mm and an outer diameter of 10 mm is used. The melting point of indium is 157 ° C. That is, in this sealing panel device, the firing temperature of the frit glass constituting the sealing member 20a is higher than that of the low melting point metal material constituting the adhesive layer 30. The lid 40 is a disk-shaped glass plate having a diameter of 15 mm and a thickness of 1 mm. The space surrounded by the lid portion 40, the adhesive layer 30, the first panel 11, the sealing member 20a, and the second panel 12 is a vacuum (VAC).

実施の形態3の封止パネル装置の製造方法を、図7を参照して説明する。焼成条件や真空排気条件は実施の形態1で述べた通りでよく、ここでは実施の形態1と相違する部分を中心に述べる。先ず、図7の(A)に示すように、第1パネル11及び第2パネル12の周縁部に、例えばフリット・ガラスから成るシール部材20cを形成する。このとき、開口部14の形成予定領域を残すようにフリット・ガラスを塗布する。また、開口部14の周辺には補助接着層33を形成しておく。補助接着層33は、シール部材20cと異なる材料を用いて構成してもよいが、シール部材20cと同じくフリット・ガラスを用いて構成することが最も簡便である。なぜなら、シール部材20cを形成する際に、フリット・ガラスを両パネルの外縁部にはみ出すように塗布すれば、補助接着層33はシール部材20cの延在部分として形成することができるからである。あるいは、補助接着層33は予め補助枠体43上に形成しておいても良く、補助接着層33シール部材20cとを互いに異なる材料にて構成する場合には、かかる方法が簡便である。 A method of manufacturing the sealing panel device according to the third embodiment will be described with reference to FIG. The firing conditions and the vacuum exhaust conditions may be as described in the first embodiment, and here, the parts different from the first embodiment will be mainly described. First, as shown in FIG. 7A, a sealing member 20c made of, for example, frit glass is formed on the peripheral edges of the first panel 11 and the second panel 12. At this time, frit glass is applied so as to leave a region to be formed of the opening 14. Further, an auxiliary adhesive layer 33 is formed around the opening 14. The auxiliary adhesive layer 33 may be formed by using a material different from that of the sealing member 20c, but it is most convenient to use frit glass as in the case of the sealing member 20c. This is because, when the seal member 20c is formed, if the frit glass is applied so as to protrude from the outer edges of both panels, the auxiliary adhesive layer 33 can be formed as an extending portion of the seal member 20c. Alternatively, the auxiliary adhesive layer 33 may be formed on the auxiliary frame 43 in advance , and such a method is convenient when the auxiliary adhesive layer 33 and the seal member 20c are made of different materials.

また、本発明の封止パネル装置を適用した表示装置においては、第1パネルと第2パネルの少なくとも一方において、パネル表面の一部はゲッターを収容するための箱部によって構成されており、かかるゲッター室には開口部が設けられており、開口部は低融点金属材料から成る接着層によってパネルを構成するゲッター室に接着された蓋部により閉鎖された構造とすることもできる。第1パネル11の表面の一部がゲッター63を収容するための箱部60で形成された封止パネル装置を概念的に図16に示す。また、かかる封止パネル装置概念的に示す分解斜視図を図17に示す。尚、図17に示した封止パネル装置の基本的な構成は実施の形態4と同様であるが、他の封止パネル装置にもゲッター63を収容するための箱部60を適用することができることは云うまでもない。ここで、これらの図面の符号は図8と一部共通であり、共通部分については詳しい説明を省略する。図17では、第1接着層21と第2接着層22の図示を省略し、第1パネル11の有効領域と第2パネル12を明確化するために斜線を施した。

Further, in the display device to which the sealing panel device of the present invention is applied, in at least one of the first panel and the second panel, a part of the panel surface is composed of a box portion for accommodating the getter. The getter chamber is provided with an opening, and the opening may be closed by a lid portion adhered to the getter chamber constituting the panel by an adhesive layer made of a low melting point metal material. FIG. 16 conceptually shows a sealing panel device in which a part of the surface of the first panel 11 is formed by a box portion 60 for accommodating the getter 63. Further, an exploded perspective view conceptually showing such a sealing panel device is shown in FIG. The basic configuration of the sealing panel device shown in FIG. 17 is the same as that of the fourth embodiment, but the box portion 60 for accommodating the getter 63 may be applied to other sealing panel devices. Needless to say, you can do it. Here, the reference numerals of these drawings are partially common to those of FIG. 8, and detailed description of the common parts will be omitted. In FIG. 17, the first adhesive layer 21 and the second adhesive layer 22 are omitted, and diagonal lines are provided to clarify the effective region of the first panel 11 and the second panel 12.
