Description

本発明は、積層体の製造装置および積層体の製造方法に関する。   The present invention relates to a laminate manufacturing apparatus and a laminate manufacturing method.

このような積層体を製造する際には、２つの部材との間に空気を挟み込むと、貼合後の粘着層が気泡を有し、信頼性の低下や外観不良などの不具合を生じるおそれがある。そのため、このような積層体の製造時には、気泡の混入を抑制するための種々の工夫がなされている。例えば、真空チャンバー内を減圧雰囲気とし、減圧雰囲気下で２枚の基板を接触させた後に真空チャンバーを大気解放することで、気泡の混入を抑制し、さらに基板間の領域の気圧と、外部の気圧との差圧を利用して２枚の基板を貼り合せる方法が知られている（例えば、特許文献１参照）。   When manufacturing such a laminate, if air is sandwiched between two members, the adhesive layer after bonding has air bubbles, which may cause problems such as reduced reliability and poor appearance. is there. For this reason, at the time of manufacturing such a laminate, various devices for suppressing the mixing of bubbles are made. For example, the inside of the vacuum chamber is set to a reduced pressure atmosphere, and after the two substrates are brought into contact with each other in the reduced pressure atmosphere, the vacuum chamber is released to the atmosphere, thereby suppressing the mixing of bubbles, and further the atmospheric pressure in the region between the substrates and the external A method of bonding two substrates using a differential pressure with respect to atmospheric pressure is known (see, for example, Patent Document 1).

（積層体の製造方法）
本実施形態の積層体の製造方法について図１〜３を用いて説明する。(Laminate manufacturing method)
The manufacturing method of the laminated body of this embodiment is demonstrated using FIGS.

（第１雰囲気とする工程）
まず、図１に示すように、支持部材１０を用いて一面に粘着層３が設けられた表示パネル１を支持する。また、第１圧力調整部２０の開口部２０ａにガラス板２を表示パネル１の表面と対向するように当接させることで、表示パネル１とガラス板２とを対向配置させるとともに、第１圧力調整部２０とガラス板２の一部とで区画された第１空間Ｓ１を形成する。この第１空間Ｓ１には、表示パネル１が収容されている。(Process to make first atmosphere)
First, as shown in FIG. 1, the display panel 1 provided with the adhesive layer 3 on one side is supported using a support member 10. In addition, the glass panel 2 is brought into contact with the opening 20a of the first pressure adjusting unit 20 so as to face the surface of the display panel 1, so that the display panel 1 and the glass sheet 2 are arranged to face each other, and the first pressure is set. A first space S1 defined by the adjustment unit 20 and a part of the glass plate 2 is formed. The display panel 1 is accommodated in the first space S1.

次いで、真空ポンプ３０を用いて第１空間Ｓ１内を大気圧よりも低い気圧雰囲気（以下、この雰囲気を「第１雰囲気」という。）に減圧する。   Next, the inside of the first space S1 is depressurized to a pressure atmosphere lower than atmospheric pressure (hereinafter, this atmosphere is referred to as “first atmosphere”) using the vacuum pump 30.

（積層させる工程）
次いで、図２に示すように、支持部材１０をガラス板２の方向に移動させて、表示パネル１とガラス板２とを近づけ、粘着層３を介して表示パネル１とガラス板２とを積層させる。(Lamination process)
Next, as shown in FIG. 2, the support member 10 is moved in the direction of the glass plate 2, the display panel 1 and the glass plate 2 are brought close to each other, and the display panel 1 and the glass plate 2 are laminated via the adhesive layer 3. Let

（押し付ける工程）
次いで、図３に示すように、リークバルブ３２を操作して第１空間Ｓ１を大気解放し、第１雰囲気である第１空間Ｓ１を、第１雰囲気より高い圧力である第２雰囲気（以下、この第１雰囲気より高い圧力である第２雰囲気を「第２雰囲気」という。）へ変化させることにより、表示パネル１とガラス板２とを第２雰囲気下に配置する。これにより、第１雰囲気と第２雰囲気との差圧を用いて、表示パネル１とガラス板２とを互いに押し付け、ガラス板２に表示パネル１を貼合する。(Pressing process)
Next, as shown in FIG. 3, the first space S <b> 1 is released to the atmosphere by operating the leak valve 32, and the first space S <b> 1, which is the first atmosphere, is discharged into a second atmosphere (hereinafter referred to as “first atmosphere”). By changing the second atmosphere having a pressure higher than that of the first atmosphere to “second atmosphere”), the display panel 1 and the glass plate 2 are arranged in the second atmosphere. Thereby, the display panel 1 and the glass plate 2 are pressed against each other using the differential pressure between the first atmosphere and the second atmosphere, and the display panel 1 is bonded to the glass plate 2.

第１空間Ｓ１を大気解放すると、表示パネル１とガラス板２とは、上昇した圧力によって互いに密着する方向に押圧される。そのため、粘着層３とガラス板２との間に空隙が存在すると、周囲からの圧力を受けた粘着層３が変形し、空隙を充填するため、空隙が消失する。
このようにして、第１部材（表示パネル１）と、前記第１部材に対向する第２部材（ガラス板２）と、前記第１部材および前記第２部材に挟持された粘着層３とが積層された積層体を製造する。When the first space S1 is released to the atmosphere, the display panel 1 and the glass plate 2 are pressed in a direction in which they are in close contact with each other by the increased pressure. Therefore, if there is a gap between the pressure-sensitive adhesive layer 3 and the glass plate 2, the pressure-sensitive adhesive layer 3 that has received pressure from the surrounding area is deformed and fills the gap, so that the gap disappears.
In this way, the first member (display panel 1), the second member (glass plate 2) facing the first member, and the adhesive layer 3 sandwiched between the first member and the second member are provided. A laminated body is produced.

以上のような構成の積層体の製造装置１０００によれば、粘着層３とガラス板２との貼合面の間に気泡が残り難く、高品質な積層体を製造することができる。   According to the laminate manufacturing apparatus 1000 configured as described above, it is difficult for bubbles to remain between the bonding surfaces of the pressure-sensitive adhesive layer 3 and the glass plate 2, and a high-quality laminate can be manufactured.

以上のような構成の積層体の製造方法によれば、粘着層３とガラス板２との貼合面の間に気泡が残り難く、高品質な積層体を製造することができる。   According to the manufacturing method of the laminated body of the above structures, it is hard to leave a bubble between the bonding surfaces of the adhesion layer 3 and the glass plate 2, and a high quality laminated body can be manufactured.

なお、本実施形態においては、製造装置１０００が支持部材１０を１つ有する構成であることとしたが、これに限らず、第１圧力調整部２０に２以上の支持部１０Ａが収容され、２以上の第１部材を第２部材に貼合することが可能な装置としてもよい。   In the present embodiment, the manufacturing apparatus 1000 is configured to have one support member 10. However, the present invention is not limited thereto, and two or more support portions 10 </ b> A are accommodated in the first pressure adjustment unit 20. It is good also as an apparatus which can paste the above 1st member on the 2nd member.

また、本実施形態の製造装置１０００の第１圧力制御手段として、第１空間Ｓ１を大気圧よりも高い圧力に加圧可能な構成を有するようにしてもよい。このような構成とすることで、表示パネル１とガラス板２とをより強い力で押しつけて貼合することができ、粘着層３とガラス板２との貼合面の間に気泡が残り難く、高品質な積層体を製造することができる。この場合、第１空間Ｓ１の加圧中に第１圧力調整部２０とガラス板２とが離間しないように、第１圧力調整部２０とガラス板２との相対位置を固定するための部材を別途設けることとするとよい。   Moreover, you may make it have a structure which can pressurize 1st space S1 to a pressure higher than atmospheric pressure as a 1st pressure control means of the manufacturing apparatus 1000 of this embodiment. By setting it as such a structure, the display panel 1 and the glass plate 2 can be pressed and bonded by stronger force, and a bubble does not remain easily between the bonding surfaces of the adhesion layer 3 and the glass plate 2. A high-quality laminate can be produced. In this case, a member for fixing the relative position between the first pressure adjusting unit 20 and the glass plate 2 is provided so that the first pressure adjusting unit 20 and the glass plate 2 are not separated during pressurization of the first space S1. It is recommended to provide it separately.

［第２実施形態］
図４は、本発明の第２実施形態に係る製造装置１１００の説明図である。本実施形態の製造装置１１００は、第１実施形態の製造装置１０００と一部共通している。したがって、本実施形態において第１実施形態と共通する構成要素については同じ符号を付し、詳細な説明は省略する。[Second Embodiment]
FIG. 4 is an explanatory diagram of the manufacturing apparatus 1100 according to the second embodiment of the present invention. The manufacturing apparatus 1100 of the present embodiment is partially in common with the manufacturing apparatus 1000 of the first embodiment. Therefore, in this embodiment, the same code | symbol is attached | subjected about the component which is common in 1st Embodiment, and detailed description is abbreviate | omitted.

製造装置１１００は、第１圧力調整部２０に対向して設けられた第２圧力調整部４０と、第２圧力調整部４０に接続された真空ポンプ（第２圧力制御手段）５０と、を有している。   The manufacturing apparatus 1100 includes a second pressure adjustment unit 40 provided to face the first pressure adjustment unit 20, and a vacuum pump (second pressure control means) 50 connected to the second pressure adjustment unit 40. doing.

第２圧力調整部４０は、第１圧力調整部２０に対向する一端に開口部４０ａを有する中空の容器である。第２圧力調整部４０の壁面には貫通孔４０ｂが設けられ、配管５１を介して真空ポンプ５０が接続されている。また、配管５１には、貫通孔４０ｂと真空ポンプ５０との間の位置に、リークバルブ５２が設けられた側管が接続されている。   The second pressure adjustment unit 40 is a hollow container having an opening 40 a at one end facing the first pressure adjustment unit 20. A through hole 40 b is provided in the wall surface of the second pressure adjusting unit 40, and the vacuum pump 50 is connected via a pipe 51. Further, a side pipe provided with a leak valve 52 is connected to the pipe 51 at a position between the through hole 40 b and the vacuum pump 50.

また、第２圧力調整部４０の端部４０ｃには、端部４０ｃに沿って封止部材４１が設けられている。封止部材４１は、ゴムやエラストマー等の樹脂材料を用いて形成されている。   Further, a sealing member 41 is provided along the end 40 c at the end 40 c of the second pressure adjusting unit 40. The sealing member 41 is formed using a resin material such as rubber or elastomer.

このような製造装置１１００においては、第１圧力調整部２０の開口部２０ａにガラス板２を表示パネル１の表面と対向するように当接させ、第１圧力調整部２０の開口部２０ａを閉じる。これにより、第１圧力調整部２０とガラス板２の一部とで区画された第１空間Ｓ１を形成する。その後、真空ポンプ３０で第１空間Ｓ１を減圧する。   In such a manufacturing apparatus 1100, the glass plate 2 is brought into contact with the opening 20a of the first pressure adjusting unit 20 so as to face the surface of the display panel 1, and the opening 20a of the first pressure adjusting unit 20 is closed. . Thereby, the 1st space S1 divided by the 1st pressure regulation part 20 and a part of glass plate 2 is formed. Thereafter, the first space S1 is decompressed by the vacuum pump 30.

このような操作を行うと、ガラス板２の厚みによっては、第１空間Ｓ１を減圧することで生じる差圧により、ガラス板２が第１空間Ｓ１側に凸となるように湾曲するおそれがある。このようにガラス板２が湾曲すると、表示パネル１（粘着層３）との貼合面において接着が不均一となりやすい。   When such an operation is performed, depending on the thickness of the glass plate 2, the glass plate 2 may be curved so as to protrude toward the first space S <b> 1 due to a differential pressure generated by reducing the pressure of the first space S <b> 1. . When the glass plate 2 is curved in this manner, the adhesion tends to be non-uniform on the bonding surface with the display panel 1 (adhesive layer 3).

そこで、製造装置１１００では、ガラス板２を挟んで第１圧力調整部２０と反対側であって、第１圧力調整部２０と平面視で対向する位置に、第２圧力調整部４０を配置し、第２圧力調整部４０の開口部４０ａにガラス板２を当接させ、第２圧力調整部４０の開口部４０ａを閉じる。これにより、第２圧力調整部４０とガラス板２の一部とで区画された第２空間Ｓ２を形成する。その後、真空ポンプ５０で第２空間Ｓ２を減圧する。このようにして、第１空間Ｓ１と第２空間Ｓ２との差圧が小さくなるように第２空間Ｓ２の圧力を制御し、ガラス板２の湾曲を抑制する。   Therefore, in the manufacturing apparatus 1100, the second pressure adjustment unit 40 is disposed at a position opposite to the first pressure adjustment unit 20 across the glass plate 2 and opposed to the first pressure adjustment unit 20 in plan view. The glass plate 2 is brought into contact with the opening 40a of the second pressure adjusting unit 40, and the opening 40a of the second pressure adjusting unit 40 is closed. Thereby, the 2nd space S2 divided by the 2nd pressure regulation part 40 and a part of glass plate 2 is formed. Thereafter, the second space S <b> 2 is decompressed by the vacuum pump 50. In this way, the pressure of the second space S2 is controlled so that the differential pressure between the first space S1 and the second space S2 is reduced, and the bending of the glass plate 2 is suppressed.

以上のような構成の積層体の製造装置１１００によれば、粘着層３とガラス板２との貼合面の間に気泡が残り難く、高品質な積層体を製造することができる。   According to the laminate manufacturing apparatus 1100 configured as described above, it is difficult for bubbles to remain between the bonding surfaces of the adhesive layer 3 and the glass plate 2, and a high-quality laminate can be manufactured.

なお、本実施形態においては、真空ポンプ５０は、第１空間Ｓ１と第２空間Ｓ２との差圧が小さくなるように第２空間Ｓ２の圧力を制御することとしたが、第２空間Ｓ２の圧力の制御の仕方はこれに限らない。   In the present embodiment, the vacuum pump 50 controls the pressure in the second space S2 so that the differential pressure between the first space S1 and the second space S2 is reduced. The method of controlling the pressure is not limited to this.

例えば、ガラス板２の板厚が薄く、ガラス板２が自重により重力方向に凸となるように撓んでしまうと、粘着層３とガラス板２との貼合面の間に気泡が残り易く、不具合が生じやすい。このような場合、真空ポンプ５０を用いて、第１空間Ｓ１および第２空間Ｓ２のうち、ガラス板２に対し重力方向下方側に形成される側の空間の圧力が高くなるように、積極的に第１空間Ｓ１と第２空間Ｓ２とに差圧を設けるとよい。このように第２空間Ｓ２の圧力を制御することで、差圧を用いてガラス板２の撓みを打ち消し、ガラス板２の湾曲を抑制することができる。   For example, if the plate thickness of the glass plate 2 is thin and the glass plate 2 bends so as to be convex in the direction of gravity due to its own weight, bubbles easily remain between the bonding surfaces of the adhesive layer 3 and the glass plate 2, Problems are likely to occur. In such a case, the vacuum pump 50 is used to positively increase the pressure in the space formed on the lower side in the gravitational direction with respect to the glass plate 2 in the first space S1 and the second space S2. In addition, a differential pressure may be provided between the first space S1 and the second space S2. By controlling the pressure in the second space S2 in this manner, the bending of the glass plate 2 can be canceled using the differential pressure, and the bending of the glass plate 2 can be suppressed.

また、粘着層３とガラス板２との貼合面の状態によっては、ガラス板２が所定の曲率を有するように湾曲している方が、好適な貼合が可能となる場合もある。そのような場合は、真空ポンプ５０を、第１空間Ｓ１と第２空間Ｓ２との差圧が、ガラス板２を所定の曲率で湾曲させるような値となるように操作し、第２空間Ｓ２の圧力を制御するとよい。   Moreover, depending on the state of the bonding surface of the adhesion layer 3 and the glass plate 2, the direction where the glass plate 2 is curving so that it may have a predetermined curvature may become suitable. In such a case, the vacuum pump 50 is operated so that the differential pressure between the first space S1 and the second space S2 becomes a value that causes the glass plate 2 to bend with a predetermined curvature, and the second space S2. It is good to control the pressure.

［第３実施形態］
図５は、本発明の第３実施形態に係る製造装置１２００の説明図である。本実施形態の製造装置１２００は、第１実施形態の製造装置１０００および第２実施形態の製造装置１１００と一部共通している。したがって、本実施形態において第１、第２実施形態と共通する構成要素については同じ符号を付し、詳細な説明は省略する。[Third Embodiment]
FIG. 5 is an explanatory diagram of a manufacturing apparatus 1200 according to the third embodiment of the present invention. The manufacturing apparatus 1200 of the present embodiment is partly in common with the manufacturing apparatus 1000 of the first embodiment and the manufacturing apparatus 1100 of the second embodiment. Therefore, in this embodiment, the same code | symbol is attached | subjected about the component which is common in 1st, 2nd embodiment, and detailed description is abbreviate | omitted.

製造装置１２００の支持部材１９が有する支持部１０Ｃには、押圧部材１２の上に第３圧力調整部６０が設けられている。第３圧力調整部６０は、ガラス板２に面する側に開口部６０ａを有する中空の容器であり、内部に表示パネル１が収容されるものである。   A third pressure adjusting unit 60 is provided on the pressing member 12 in the supporting unit 10 </ b> C included in the supporting member 19 of the manufacturing apparatus 1200. The 3rd pressure adjustment part 60 is a hollow container which has the opening part 60a in the side which faces the glass plate 2, and the display panel 1 is accommodated in an inside.

第３圧力調整部６０は、板状の中間板６１と、中間板６１の周縁に平面視で連続する円環状に設けられた裾部６２と、を有している。裾部６２は、ゴムやエラストマー等の樹脂材料で形成されている。   The third pressure adjusting unit 60 includes a plate-shaped intermediate plate 61 and a hem 62 provided in an annular shape that is continuous with the periphery of the intermediate plate 61 in plan view. The skirt 62 is made of a resin material such as rubber or elastomer.

製造装置１２００においては、第３圧力調整部６０の開口部６０ａにガラス板２を表示パネル１の表面と対向するように当接させ、開口部６０ａを閉じる。これにより、第３圧力調整部６０とガラス板２の一部とで区画された第３空間Ｓ３を形成する。この状態で、第１圧力調整部２０により形成される第１空間Ｓ１の圧力を、第３圧力調整部６０により形成される第３空間Ｓ３の圧力よりも高圧とし、第１空間Ｓ１と第３空間Ｓ３との間で差圧を生じさせると、第３圧力調整部６０は差圧に応じて容積を縮小させるように変形する。   In the manufacturing apparatus 1200, the glass plate 2 is brought into contact with the opening 60a of the third pressure adjusting unit 60 so as to face the surface of the display panel 1, and the opening 60a is closed. Thereby, the 3rd space S3 divided by the 3rd pressure regulation part 60 and a part of glass plate 2 is formed. In this state, the pressure in the first space S1 formed by the first pressure adjusting unit 20 is set to be higher than the pressure in the third space S3 formed by the third pressure adjusting unit 60, and the first space S1 and the third space When a differential pressure is generated between the space S3, the third pressure adjusting unit 60 is deformed so as to reduce the volume according to the differential pressure.

また、第３圧力調整部６０は、一端が開口し、第３圧力調整部６０を収容する空間を有する第１圧力調整部２０に収容されている。第１圧力調整部２０には、配管３１を介して真空ポンプ（第１圧力制御手段、第３圧力制御手段）３０が接続されている。   The third pressure adjusting unit 60 is accommodated in the first pressure adjusting unit 20 having one end opened and a space for accommodating the third pressure adjusting unit 60. A vacuum pump (first pressure control means, third pressure control means) 30 is connected to the first pressure adjustment unit 20 via a pipe 31.

第１圧力調整部２０は、第３圧力調整部６０よりも高い剛性を有する材料で形成されており、第１圧力調整部２０の内外に差圧が生じても変形しない程度の強度を有している。   The first pressure adjusting unit 20 is made of a material having higher rigidity than the third pressure adjusting unit 60, and has a strength that does not deform even if a differential pressure occurs inside and outside the first pressure adjusting unit 20. ing.

第１圧力調整部２０は、開口部２０ａにガラス板２を表示パネル１の表面と対向するように当接させ、開口部２０ａを閉じる。これにより、第１圧力調整部２０とガラス板２の一部とで区画された第１空間Ｓ１を形成する。   The 1st pressure adjustment part 20 makes the glass plate 2 contact | abut so that the surface of the display panel 1 may be opposed to the opening part 20a, and closes the opening part 20a. Thereby, the 1st space S1 divided by the 1st pressure regulation part 20 and a part of glass plate 2 is formed.

支持部材１９は、第１圧力調整部２０が第１空間Ｓ１を形成した状態で、移動部１０Ｂを進退させることにより第３圧力調整部６０を表示パネル１の厚み方向に進退移動させる。これにより、第３圧力調整部６０とガラス板２とが離間し第１空間Ｓ１が第３空間Ｓ３と連通する第１の状態と、第３圧力調整部６０とガラス板２とが当接し第１空間Ｓ１と第３空間Ｓ３とが隔離された第２の状態と、を作り出すことができる。   The support member 19 moves the third pressure adjusting unit 60 forward and backward in the thickness direction of the display panel 1 by moving the moving unit 10 </ b> B in a state where the first pressure adjusting unit 20 forms the first space S <b> 1. As a result, the third pressure adjusting unit 60 and the glass plate 2 are separated from each other and the first space S1 communicates with the third space S3, and the third pressure adjusting unit 60 and the glass plate 2 come into contact with each other. A second state in which the first space S1 and the third space S3 are isolated can be created.

このような製造装置１２００においては、第１圧力調整部２０の開口部２０ａにガラス板２を当接させて第１空間Ｓ１を形成し、第１の状態とする。その後、第１空間Ｓ１と第３空間Ｓ３とに共通する圧力制御手段である真空ポンプ３０を用い、第１空間Ｓ１と第３空間Ｓ３とを、大気圧よりも低い気圧雰囲気（第１雰囲気）にまで減圧する。すなわち、真空ポンプ３０が、第１空間Ｓ１の圧力を制御する圧力制御手段（第１圧力制御手段）と、第３空間Ｓ３の圧力を制御する圧力制御手段（第３圧力制御手段）と、を兼ねている。   In such a manufacturing apparatus 1200, the glass plate 2 is brought into contact with the opening 20a of the first pressure adjusting unit 20 to form the first space S1, and the first state is set. After that, using the vacuum pump 30 which is a pressure control means common to the first space S1 and the third space S3, the first space S1 and the third space S3 are separated from the atmospheric pressure by the atmospheric pressure (first atmosphere). Depressurize until. That is, the vacuum pump 30 includes pressure control means (first pressure control means) for controlling the pressure in the first space S1, and pressure control means (third pressure control means) for controlling the pressure in the third space S3. Also serves as.

また、第２圧力調整部４０の開口部４０ａにガラス板２を当接させ、第２圧力調整部４０の開口部４０ａを閉じる。これにより、第２圧力調整部４０とガラス板２の一部とで区画された第２空間Ｓ２を形成する。その後、真空ポンプ５０で第２空間Ｓ２を減圧する。これにより、第２空間Ｓ２と第１空間Ｓ１との差圧が小さくなるように制御することができ、ガラス板２の湾曲を抑制することができる。   Further, the glass plate 2 is brought into contact with the opening 40 a of the second pressure adjustment unit 40, and the opening 40 a of the second pressure adjustment unit 40 is closed. Thereby, the 2nd space S2 divided by the 2nd pressure regulation part 40 and a part of glass plate 2 is formed. Thereafter, the second space S <b> 2 is decompressed by the vacuum pump 50. Thereby, it can control so that the differential pressure | voltage of 2nd space S2 and 1st space S1 may become small, and the curvature of the glass plate 2 can be suppressed.

次いで、図６に示すように、支持部材１９を駆動させて第３圧力調整部６０をガラス板２に当接させ、第１空間Ｓ１と第３空間Ｓ３とが隔離された第２の状態とする。この際、第１空間Ｓ１の内部圧力は、第３空間Ｓ３と同じ圧力となる。   Next, as shown in FIG. 6, the support member 19 is driven to bring the third pressure adjustment unit 60 into contact with the glass plate 2, and the second state in which the first space S1 and the third space S3 are isolated from each other; To do. At this time, the internal pressure of the first space S1 is the same pressure as that of the third space S3.

次いで、リークバルブ３２を操作して第１空間Ｓ１を大気解放し、第１雰囲気である第１空間Ｓ１を、第１雰囲気より高い圧力である第２雰囲気へ変化させることにより、第３圧力調整部６０を第２雰囲気にする。これにより、第３圧力調整部６０は、第１雰囲気である第３空間Ｓ３と第２雰囲気である第１空間Ｓ１との差圧により押圧され、差圧に応じて変形する。第３圧力調整部６０は、変形しながら表示パネル１とガラス板２とを押し付け、ガラス板２に表示パネル１を貼合する。   Next, the third pressure adjustment is performed by operating the leak valve 32 to release the first space S1 to the atmosphere and changing the first space S1, which is the first atmosphere, to the second atmosphere, which has a higher pressure than the first atmosphere. The part 60 is set to the second atmosphere. Thereby, the 3rd pressure adjustment part 60 is pressed by the differential pressure of 3rd space S3 which is 1st atmosphere, and 1st space S1 which is 2nd atmosphere, and deform | transforms according to differential pressure. The third pressure adjusting unit 60 presses the display panel 1 and the glass plate 2 while being deformed, and bonds the display panel 1 to the glass plate 2.

このとき、図７に示すように、第３空間Ｓ３は、大気解放された第１空間Ｓ１と隔離されているため、貼合中に粘着層３の端部が空気に触れることがない。そのため、貼合中の粘着層３の端部における気泡の残留や気体の吸収を抑制することができ、剥離を抑制することができる。   At this time, as shown in FIG. 7, since the third space S3 is isolated from the first space S1 released to the atmosphere, the end portion of the adhesive layer 3 does not come into contact with air during bonding. Therefore, it is possible to suppress residual bubbles and gas absorption at the end of the pressure-sensitive adhesive layer 3 being bonded, and to suppress peeling.

以上のような構成の積層体の製造装置１２００によれば、粘着層３とガラス板２との貼合面の間に気泡が残り難く、高品質な積層体を製造することができる。   According to the laminate manufacturing apparatus 1200 configured as described above, it is difficult for bubbles to remain between the bonding surfaces of the adhesive layer 3 and the glass plate 2, and a high-quality laminate can be manufactured.

なお、本実施形態の製造装置１２００は、第２圧力調整部４０を有することとしたが、第２圧力調整部４０を有さない構成とすることもできる。   In addition, although the manufacturing apparatus 1200 of this embodiment has the 2nd pressure adjustment part 40, it can also be set as the structure which does not have the 2nd pressure adjustment part 40. FIG.

また、本実施形態の製造装置１２００の第１圧力制御手段として、上記した第２の状態において第１空間Ｓ１を大気圧よりも高い圧力に加圧可能な構成を有するようにしてもよい。このような構成とすることで、表示パネル１とガラス板２とをより強い力で押しつけて貼合することができ、粘着層３とガラス板２との貼合面の間に気泡が残り難く、高品質な積層体を製造することができる。この場合、第１空間Ｓ１の加圧中に第１圧力調整部２０とガラス板２とが離間しないように、第１圧力調整部２０とガラス板２との相対位置を固定するための部材を別途設けることとするとよい。   Moreover, you may make it have a structure which can pressurize 1st space S1 to a pressure higher than atmospheric pressure in the above-mentioned 2nd state as a 1st pressure control means of the manufacturing apparatus 1200 of this embodiment. By setting it as such a structure, the display panel 1 and the glass plate 2 can be pressed and bonded by stronger force, and a bubble does not remain easily between the bonding surfaces of the adhesion layer 3 and the glass plate 2. A high-quality laminate can be produced. In this case, a member for fixing the relative position between the first pressure adjusting unit 20 and the glass plate 2 is provided so that the first pressure adjusting unit 20 and the glass plate 2 are not separated during pressurization of the first space S1. It is recommended to provide it separately.

また、本実施形態の製造装置１２００においては、第３圧力調整部６０が板状の中間板６１と、中間板６１の周縁に平面視で連続する円環状に設けられた裾部６２と、を有する構成であることとしたが、これに限らない。例えば、中間板６１のような剛性の高い構造を含まず、例えば樹脂材料で形成された袋状の構成であっても構わない。   Further, in the manufacturing apparatus 1200 of the present embodiment, the third pressure adjusting unit 60 includes a plate-shaped intermediate plate 61 and a skirt portion 62 provided in an annular shape that is continuous with the periphery of the intermediate plate 61 in plan view. However, the present invention is not limited to this. For example, it does not include a highly rigid structure such as the intermediate plate 61 and may have a bag-like configuration formed of, for example, a resin material.

（変形例）
また、本実施形態の製造装置１２００においては、真空ポンプ３０を用いて、第１空間Ｓ１と第３空間Ｓ３とを減圧することとしたが、第１空間Ｓ１と第３空間Ｓ３との圧力をそれぞれ独立して制御可能な構成を採用することもできる。(Modification)
In the manufacturing apparatus 1200 of the present embodiment, the first space S1 and the third space S3 are depressurized using the vacuum pump 30, but the pressure in the first space S1 and the third space S3 is changed. It is also possible to adopt a configuration that can be independently controlled.

図８、９は、上記した第３実施形態に係る製造装置の変形例を示す図であり、図５に対応する図である。   8 and 9 are diagrams showing a modification of the manufacturing apparatus according to the third embodiment described above, and correspond to FIG.

（変形例１）
図８に示す製造装置１３００において、第３圧力調整部６０には貫通孔６１ａが設けられ、第１圧力調整部２０には貫通孔２０ｅが設けられており、貫通孔６１ａには、配管６４および貫通孔２０ｅを介して真空ポンプ（第３圧力制御手段）６３が接続されている。また、配管６４には、貫通孔２０ｅと真空ポンプ６３との間の位置に、リークバルブ６９が設けられた側管が接続されている。(Modification 1)
In the manufacturing apparatus 1300 shown in FIG. 8, the third pressure adjusting unit 60 is provided with a through hole 61a, the first pressure adjusting unit 20 is provided with a through hole 20e, and the through hole 61a includes a pipe 64 and A vacuum pump (third pressure control means) 63 is connected through the through hole 20e. In addition, a side pipe provided with a leak valve 69 is connected to the pipe 64 at a position between the through hole 20 e and the vacuum pump 63.

このような構成の製造装置１３００においては、真空ポンプ６３を用いて第３空間Ｓ３の圧力を制御できる。本実施形態で示したように、第１空間Ｓ１および第３空間Ｓ３を共に減圧した後に、第１空間Ｓ１のみ大気解放すると、ガラス板２と第３圧力調整部６０との界面から第３空間Ｓ３に空気が侵入しやすく、第３空間Ｓ３を所定時間（例えば、表示パネル１とガラス板２との貼合が完了するまでの間）減圧状態に維持することが難しい。しかし、製造装置１３００においては、真空ポンプ６３を用いて第３空間Ｓ３の圧力を独立して制御可能であるため、第１空間Ｓ１の圧力雰囲気に関わらず、第３空間Ｓ３を減圧し、第３空間Ｓ３の減圧状態を維持することが容易となる。   In the manufacturing apparatus 1300 having such a configuration, the pressure in the third space S3 can be controlled using the vacuum pump 63. As shown in the present embodiment, after decompressing both the first space S1 and the third space S3, if only the first space S1 is released to the atmosphere, the third space is released from the interface between the glass plate 2 and the third pressure adjustment unit 60. Air easily enters S3, and it is difficult to maintain the third space S3 in a reduced pressure state for a predetermined time (for example, until the bonding of the display panel 1 and the glass plate 2 is completed). However, in the manufacturing apparatus 1300, since the pressure of the third space S3 can be controlled independently using the vacuum pump 63, the third space S3 is decompressed regardless of the pressure atmosphere of the first space S1, It becomes easy to maintain the reduced pressure state of the three spaces S3.

（変形例２）
図９に示す製造装置１４００において、第３圧力調整部６０には貫通孔６１ａが設けられ、第１圧力調整部２０には貫通孔２０ｅが設けられており、貫通孔６１ａおよび貫通孔２０ｅには配管６４が接続され連通している。配管６４の端部には、バルブ６６が設けられている。(Modification 2)
In the manufacturing apparatus 1400 shown in FIG. 9, the third pressure adjusting unit 60 is provided with a through hole 61a, the first pressure adjusting unit 20 is provided with a through hole 20e, and the through hole 61a and the through hole 20e are provided with a through hole 61a. A pipe 64 is connected and communicated. A valve 66 is provided at the end of the pipe 64.

一方、配管３１には、真空ポンプ３０と貫通孔２０ｄとの間にバルブ６８が設けられている。   On the other hand, the pipe 31 is provided with a valve 68 between the vacuum pump 30 and the through hole 20d.

また、配管６４と配管３１とは、配管６５で接続されている。配管６５は、配管６４のバルブ６６と貫通孔２０ｅとの間の位置と、配管３１の真空ポンプ３０とバルブ６８との間の位置と、を接続している。配管６５にはバルブ６７が設けられている。   The pipe 64 and the pipe 31 are connected by a pipe 65. The pipe 65 connects a position between the valve 66 and the through hole 20 e of the pipe 64 and a position between the vacuum pump 30 and the valve 68 of the pipe 31. The piping 65 is provided with a valve 67.

このような構成の製造装置１４００では、第１空間Ｓ１および第３空間Ｓ３の圧力制御を、両者に共通する圧力制御手段である真空ポンプ３０を用いて行う。すなわち、真空ポンプ３０が、第１空間Ｓ１の圧力を制御する圧力制御手段（第１圧力制御手段）と、第３空間Ｓ３の圧力を制御する圧力制御手段（第３圧力制御手段）と、を兼ねている。   In the manufacturing apparatus 1400 having such a configuration, the pressure control of the first space S1 and the third space S3 is performed using the vacuum pump 30 which is pressure control means common to both. That is, the vacuum pump 30 includes pressure control means (first pressure control means) for controlling the pressure in the first space S1, and pressure control means (third pressure control means) for controlling the pressure in the third space S3. Also serves as.

製造装置１４００では、真空ポンプ３０を駆動させ、バルブ６６，６７，６８を適宜開閉することにより、第１空間Ｓ１および第３空間Ｓ３のいずれか一方または両方を減圧することができる。また、真空ポンプ３０を駆動させず、リークバルブ３２、バルブ６６，６７，６８を適宜開閉することにより、第１空間Ｓ１および第３空間Ｓ３のいずれか一方または両方を大気解放して、第１空間Ｓ１および第３空間Ｓ３の圧力制御を行うことができる。   In the manufacturing apparatus 1400, either or both of the first space S1 and the third space S3 can be decompressed by driving the vacuum pump 30 and appropriately opening and closing the valves 66, 67, and 68. Further, by opening and closing the leak valve 32 and the valves 66, 67, 68 as appropriate without driving the vacuum pump 30, one or both of the first space S1 and the third space S3 are released to the atmosphere, and the first The pressure control of the space S1 and the third space S3 can be performed.

このような構成の製造装置１４００であっても、第３空間Ｓ３の圧力を独立して制御可能であるため、第１空間Ｓ１の圧力雰囲気に関わらず、第３空間Ｓ３を減圧し、第３空間Ｓ３の減圧状態を維持することが容易となる。   Even in the manufacturing apparatus 1400 having such a configuration, since the pressure in the third space S3 can be controlled independently, the third space S3 is decompressed and the third space S3 is reduced regardless of the pressure atmosphere in the first space S1. It becomes easy to maintain the decompressed state of the space S3.

［第４実施形態］
また、上述した実施形態においては、第１部材として表示パネルに粘着層がすでに設けられていることとして、積層体を製造する工程を説明したが、本発明を用いて、ガラス板（第２部材）表面に粘着層を形成することもできる。[Fourth Embodiment]
In the above-described embodiment, the step of manufacturing the laminate has been described on the assumption that the adhesive layer is already provided on the display panel as the first member. However, using the present invention, a glass plate (second member) is described. ) An adhesive layer can also be formed on the surface.

図１０は、ガラス板２上に粘着層を形成する工程を示す工程図であり、ガラス板２の厚み方向と平行な平面による断面図である。   FIG. 10 is a process diagram illustrating a process of forming an adhesive layer on the glass plate 2, and is a cross-sectional view taken along a plane parallel to the thickness direction of the glass plate 2.

（前駆体の層を形成する工程）
まず、図１０（ａ）に示すように、ガラス板２の上に、液状の第１粘着材料を平面視で閉環状に塗布する（あるいは、配置する）。塗布、あるいは配置する第１粘着材料は、硬化性の樹脂組成物であり、光硬化性樹脂組成物であってもよく、熱硬化性樹脂組成物であってもよい。第１粘着材料としては、低温で硬化でき、かつ硬化速度が速い点から、硬化性化合物および光重合開始剤を含む光硬化性樹脂組成物が好ましい。本実施形態では、第１粘着材料として、光硬化性樹脂組成物を用いることとして説明する。(Step of forming a precursor layer)
First, as shown to Fig.10 (a), the liquid 1st adhesion material is apply | coated to a glass plate 2 in a closed ring shape (or arrange | positioning) by planar view. The first adhesive material to be applied or arranged is a curable resin composition, which may be a photocurable resin composition or a thermosetting resin composition. As the first pressure-sensitive adhesive material, a photocurable resin composition containing a curable compound and a photopolymerization initiator is preferable because it can be cured at a low temperature and has a high curing rate. In the present embodiment, description will be made assuming that a photocurable resin composition is used as the first adhesive material.

塗布した第１粘着材料は、後述する工程において配置する第２粘着材料の塗れ広がりを堰き止める機能を有する。また、第１粘着材料が完全に硬化する前であることから、第１粘着材料の塗布により形成される構成を未硬化堰状部４と称する。   The applied first pressure-sensitive adhesive material has a function of blocking the spread of the second pressure-sensitive adhesive material disposed in a process described later. In addition, since the first adhesive material is not completely cured, the configuration formed by applying the first adhesive material is referred to as an uncured weir-like portion 4.

次いで、図１０（ｂ）に示すように、未硬化堰状部４で囲まれた領域に液状の第２粘着材料を塗布（配置）する。配置する第２粘着材料は、硬化性の樹脂組成物であり、光硬化性樹脂組成物であってもよく、熱硬化性樹脂組成物であってもよい。第２粘着材料としては、低温で硬化でき、かつ硬化速度が速い点から、硬化性化合物および光重合開始剤を含む光硬化性樹脂組成物が好ましい。本実施形態では、第２粘着材料として、光硬化性樹脂組成物を用いることとして説明する。   Next, as shown in FIG. 10 (b), a liquid second adhesive material is applied (arranged) to a region surrounded by the uncured dam-like portion 4. The second adhesive material to be disposed is a curable resin composition, and may be a photocurable resin composition or a thermosetting resin composition. As the second adhesive material, a photocurable resin composition containing a curable compound and a photopolymerization initiator is preferable because it can be cured at a low temperature and has a high curing rate. This embodiment demonstrates as using a photocurable resin composition as a 2nd adhesion material.

第２粘着材料の塗布量は、未硬化堰状部４、ガラス板２、および後述の図１０（ｃ）で示す保護フィルムによって形成される空間が第２粘着材料によって充填され、かつガラス板２と保護フィルム７との間を、予め設定した間隔とするだけの分量に設定する。この際、第２粘着材料の塗布量は、第２粘着材料の硬化収縮による体積減少をあらかじめ考慮することが好ましい。よって、該塗布量は、前記空間の容積を満たす量よりも若干多い量が好ましい。   The application amount of the second adhesive material is such that the space formed by the uncured weir 4, the glass plate 2, and a protective film shown in FIG. 10C described later is filled with the second adhesive material, and the glass plate 2. And the protective film 7 are set to an amount sufficient for a predetermined interval. At this time, it is preferable that the application amount of the second pressure-sensitive adhesive material takes into consideration the volume reduction due to the curing shrinkage of the second pressure-sensitive adhesive material in advance. Therefore, the coating amount is preferably slightly larger than the amount that fills the volume of the space.

第２粘着材料の塗布方法としては、ガラス板２を平置きにし、ディスペンサ、ダイコータ等の供給手段によって、点状、線状、帯状または面状に塗布する方法が挙げられる。たとえば、ディスペンサ７０を公知の水平移動機構によって水平方向に走査しながら第２粘着材料を塗布することとするとよい。   Examples of the method for applying the second adhesive material include a method in which the glass plate 2 is placed flat and applied in a dotted, linear, belt-like or planar shape by a supply means such as a dispenser or a die coater. For example, the second adhesive material may be applied while the dispenser 70 is scanned in the horizontal direction by a known horizontal movement mechanism.

以下の説明では、第２粘着材料を塗布することにより、未硬化堰状部４に囲まれた領域に配置される第２粘着材料の層状の構成を、第２粘着材料が硬化する前であることから未硬化層状部５と称する。未硬化堰状部４と未硬化層状部５とを合わせた構成が、本発明における「粘着層の前駆体の層」に該当する。以下の説明では、「粘着層の前駆体の層」を前駆体層６と称する。   In the following description, by applying the second adhesive material, the layered configuration of the second adhesive material arranged in the region surrounded by the uncured weir-like portion 4 is before the second adhesive material is cured. Therefore, it is referred to as an uncured layered portion 5. A configuration in which the uncured weir-like portion 4 and the uncured layer-like portion 5 are combined corresponds to the “adhesive layer precursor layer” in the present invention. In the following description, the “adhesive layer precursor layer” is referred to as a precursor layer 6.

（第１雰囲気とする工程）
次いで、図１０（ｃ）に示すように、例えば製造装置１０００において、ガラス板２よりも平面視で小さい輪郭を有する保護フィルム７が貼着された支持面材８を、支持部１０Ａで支持する。また、保護フィルム７に対し、前駆体層６が形成されたガラス板２を対向配置する。支持面材８は、保護フィルム７を保持するため治具であり、たとえばガラス板等が用いられる。
第４実施形態において、ガラス板２は本発明の請求項１（以下、本発明という）における第１部材に相当し、保護フィルム７が本発明の第２部材に相当し、前駆体層６が本発明の粘着層に相当する。(Process to make first atmosphere)
Next, as illustrated in FIG. 10C, for example, in the manufacturing apparatus 1000, the supporting surface material 8 to which the protective film 7 having a smaller outline in plan view than the glass plate 2 is attached is supported by the supporting portion 10 </ b> A. . Further, the glass plate 2 on which the precursor layer 6 is formed is disposed opposite to the protective film 7. The support surface material 8 is a jig for holding the protective film 7, and for example, a glass plate or the like is used.
In 4th Embodiment, the glass plate 2 is corresponded to the 1st member in Claim 1 (henceforth this invention) of this invention, the protective film 7 is equivalent to the 2nd member of this invention, and the precursor layer 6 is formed. It corresponds to the adhesive layer of the present invention.

次いで、第１圧力調整部２０の開口部２０ａにガラス板２を当接させ、第１圧力調整部２０の開口部２０ａを閉じる。これにより、第１圧力調整部２０とガラス板２の一部とで区画された第１空間Ｓ１を形成する。その後、真空ポンプ３０で第１空間Ｓ１を所定の減圧雰囲気（第１雰囲気）に減圧することで、気泡の原因となる空気を低減させる。   Next, the glass plate 2 is brought into contact with the opening 20 a of the first pressure adjustment unit 20, and the opening 20 a of the first pressure adjustment unit 20 is closed. Thereby, the 1st space S1 divided by the 1st pressure regulation part 20 and a part of glass plate 2 is formed. Thereafter, the vacuum pump 30 reduces the pressure of the first space S1 to a predetermined reduced pressure atmosphere (first atmosphere), thereby reducing air that causes bubbles.

（積層させる工程）
第１空間Ｓ１の雰囲気圧力が、第１雰囲気に達した後、支持部材１０を駆動させてガラス板２と保護フィルム７とを重ね合せる。重ね合わせの際、支持面材８の自重、支持部材１０からの押圧等によって、未硬化層状部５（すなわち、第２粘着材料）が押し広げられ、密封空間内に第２粘着材料が充満するように、未硬化層状部５が変形する。(Lamination process)
After the atmospheric pressure in the first space S1 reaches the first atmosphere, the support member 10 is driven to overlap the glass plate 2 and the protective film 7. At the time of superposition, the uncured layered portion 5 (that is, the second adhesive material) is spread by the weight of the support surface material 8, the pressure from the support member 10, and the second adhesive material is filled in the sealed space. Thus, the uncured layered portion 5 is deformed.

（押し付ける工程）
その後、例えば、第１空間Ｓ１を大気解放することで、ガラス板２と前駆体層６と保護フィルム７とを重ね合わせた積層体（以下、未硬化積層体と称する。）を、重ね合せ時の減圧雰囲気よりも高圧の圧力雰囲気（第２雰囲気）に置く。(Pressing process)
Thereafter, for example, by releasing the first space S1 to the atmosphere, a laminated body (hereinafter referred to as an uncured laminated body) in which the glass plate 2, the precursor layer 6, and the protective film 7 are overlapped is overlapped. The pressure atmosphere (second atmosphere) is higher than the reduced pressure atmosphere.

未硬化積層体を第２雰囲気下に置くと、第１雰囲気と第２雰囲気との差圧により、ガラス板２と保護フィルム７とが密着する方向に押圧される。そのため、未硬化積層体の密封空間に第２粘着材料が配置されていない空隙が存在すると、該空隙に未硬化層状部５を構成する第２粘着材料が流動していき、密封空間全体が未硬化層状部５によって均一に充填される。   When the uncured laminate is placed in the second atmosphere, the glass plate 2 and the protective film 7 are pressed in the direction in which they are in close contact with each other due to the differential pressure between the first atmosphere and the second atmosphere. For this reason, if there is a void in which the second adhesive material is not disposed in the sealed space of the uncured laminate, the second adhesive material constituting the uncured layered portion 5 flows in the void, and the entire sealed space is not yet unfilled. The cured layered portion 5 is uniformly filled.

なお、前駆体層６を構成する未硬化堰状部４や未硬化層状部５が液状であり、ガラス板２を傾けると配置位置が変位してしまうような場合は、図に示すように前駆体層６を上方に向けた状態で操作を行うとよい。もちろん、ガラス板２を傾けても前駆体層６の配置位置が変位しない場合には、操作中の姿勢は問わない。   In addition, when the uncured weir-like portion 4 and the uncured layer-like portion 5 constituting the precursor layer 6 are in a liquid state and the arrangement position is displaced when the glass plate 2 is tilted, the precursor is shown in the figure. The operation may be performed with the body layer 6 facing upward. Of course, if the position of the precursor layer 6 is not displaced even when the glass plate 2 is tilted, the posture during operation is not limited.

（粘着層を形成する工程）
次いで、図１０（ｄ）に示すように、前駆体層６（未硬化堰状部４および未硬化層状部５）を硬化させることによって、粘着層３を形成し、ガラス板２と粘着層３と保護フィルム７とが積層した積層体（以下、積層体と称する。）を得る。この際、未硬化堰状部４は、未硬化層状部５の硬化と同時に硬化させてもよく、未硬化層状部５の硬化の前にあらかじめ硬化させてもよい。(Step of forming the adhesive layer)
Next, as shown in FIG. 10 (d), the adhesive layer 3 is formed by curing the precursor layer 6 (uncured weir-like portion 4 and uncured layer-like portion 5), and the glass plate 2 and the adhesive layer 3. And a protective film 7 are laminated (hereinafter referred to as a laminated body). At this time, the uncured dam-like portion 4 may be cured at the same time as the uncured layered portion 5 is cured, or may be cured in advance before the uncured layered portion 5 is cured.

本実施形態においては、前駆体層６（未硬化堰状部４および未硬化層状部５）は、光硬化樹脂組成物からなるため、光Ｌを照射して硬化させる。たとえば、光源（紫外線ランプ、高圧水銀灯、ＵＶ−ＬＥＤ等）から紫外線または短波長の可視光（光Ｌ）を照射して、前駆体層６を硬化させる。   In the present embodiment, the precursor layer 6 (uncured dam-like portion 4 and uncured layer-like portion 5) is made of a photo-curing resin composition, and is therefore cured by irradiation with light L. For example, the precursor layer 6 is cured by irradiating ultraviolet light or short wavelength visible light (light L) from a light source (ultraviolet lamp, high pressure mercury lamp, UV-LED, etc.).

光Ｌは、ガラス板２側から照射してもよく、支持面材８側から照射してもよい。また、たとえば、ガラス板２に反射防止層が設けられる場合や、ガラス板２から未硬化層状部５までの間に光を透過しない層が設けられる場合には、同様に支持面材８側から光Ｌを照射する。   The light L may be irradiated from the glass plate 2 side or from the support surface material 8 side. In addition, for example, when an antireflection layer is provided on the glass plate 2 or when a layer that does not transmit light is provided between the glass plate 2 and the uncured layered portion 5, similarly, from the support surface material 8 side. Irradiate light L.

次いで、保護フィルム７から支持面材８を剥離して除去することで、最終的にガラス板２（第１部材）、粘着層３（前駆体層６）、保護フィルム７（第２部材）が積層した積層体を製造することができる。   Next, the support surface material 8 is peeled off and removed from the protective film 7, so that the glass plate 2 (first member), the adhesive layer 3 (precursor layer 6), and the protective film 7 (second member) are finally obtained. A laminated body can be produced.

以上のような構成の積層体の製造方法によれば、粘着層３と保護フィルム７との間に気泡が残り難く、高品質な積層体を製造することができる。   According to the method for manufacturing a laminate having the above-described configuration, it is difficult for air bubbles to remain between the adhesive layer 3 and the protective film 7, and a high-quality laminate can be manufactured.

以上、添付図面を参照しながら本発明に係る好適な実施の形態例について説明したが、本発明は、係る例に限定されないことは言うまでもない。上述した例において示した各構成部材の諸形状や組み合わせ等は一例であって、本発明の主旨から逸脱しない範囲において設計要求等に基づき種々変更可能である。   The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples.

Moreover, this invention is applicable also as providing in both the 1st member and the 2nd member.

その他、本発明の効果を損なわない範囲において、第１部材および第２部材の材質、透明度（光透過性）や大きさは特に限定されず、例えば建築材料や自動車の合わせガラス、太陽電池パネル、センサー等の製造工程における貼り合わせにも好適に用いることができる。   In addition, the material, transparency (light transmittance) and size of the first member and the second member are not particularly limited as long as the effects of the present invention are not impaired. For example, building materials and laminated glass for automobiles, solar battery panels, It can also be suitably used for bonding in manufacturing processes such as sensors.

また、第１部材および第２部材の貼合面が曲面を有する場合や、第１部材および第２部材がフィルム状の部材である場合にも、本発明を適用することで、好適に貼り合せができる。   Moreover, also when the bonding surface of a 1st member and a 2nd member has a curved surface, and when a 1st member and a 2nd member are film-shaped members, it is bonded suitably by applying this invention. Can do.

本発明によれば、貼合面の間に気泡が残り難い積層体の製造装置および積層体の製造方法を提供することができ、特に、表示装置用の表示パネルの表示面に保護材として適用される積層体の製造装置およびその製造方法として有用である。
