Description

本発明は、液状体が注入される注入口を有するパネルの製造方法に関する。   The present invention relates to a method for manufacturing a panel having an injection port into which a liquid material is injected.

従来、この種のパネルである液晶パネルの製造方法としては、液晶が注入された複数の液晶パネルと板状の複数の緩衝材とを交互に重ね合わせた状態で加圧プレート間に配置させ、これら加圧プレートにて各液晶パネルそれぞれのセルギャップが均一になるまで、これら加圧プレートをシリンダなどにて加圧する。この後、これら液晶パネルそれぞれの液晶注入口を封止するために、これら液晶パネルそれぞれの液晶注入口に封止材をディスペンサにて塗布してから、この封止材に紫外線(UV)を照射して硬化させて、各液晶パネルそれぞれの液晶注入口を封止させる加圧封止方法が知られている(例えば、特許文献1参照。)。
特開2003−177412号公報
Conventionally, as a method of manufacturing a liquid crystal panel which is this type of panel, a plurality of liquid crystal panels into which liquid crystal is injected and a plurality of plate-like buffer materials are alternately placed between pressure plates, These pressure plates are pressurized with a cylinder or the like until the cell gap of each liquid crystal panel becomes uniform with these pressure plates. Thereafter, in order to seal the liquid crystal injection port of each of these liquid crystal panels, a sealing material is applied to the liquid crystal injection port of each of these liquid crystal panels with a dispenser, and then the ultraviolet ray (UV) is irradiated to the sealing material. A pressure sealing method is known in which the liquid crystal injection port of each liquid crystal panel is sealed by being cured (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 2003-177412

しかしながら、上述の加圧封止方法では、液晶パネルの厚さが薄くなるに伴って、これら液晶パネルの端部のみに封止材を塗布することが容易ではなくなり、これら液晶パネルの端部に塗布した封止材が垂れて液晶パネルの表面に固着してしまうおそれがある。そして、この固着した封止材は、洗浄機等による除去が容易ではなくカッター等の刃物で除去する必要がある。   However, in the above-described pressure sealing method, as the thickness of the liquid crystal panel is reduced, it is not easy to apply the sealing material only to the end portions of these liquid crystal panels. There is a possibility that the applied sealing material may drip and adhere to the surface of the liquid crystal panel. And this fixed sealing material is not easy to remove by a washing machine or the like, and needs to be removed by a cutter such as a cutter.

また、この封止材が完全に除去できなかったり、再び付着した封止材が偏光板と液晶パネルとの間に異物として入り込んでしまったりして、この液晶パネルに不良が発生するおそれがあるという問題を有している。   In addition, the sealing material may not be completely removed or the reattached sealing material may enter as a foreign substance between the polarizing plate and the liquid crystal panel, which may cause defects in the liquid crystal panel. Has the problem.

本発明は、このような点に鑑みなされたもので、不良を防止できるパネルの製造方法を提供することを目的とする。   The present invention has been made in view of these points, and an object of the present invention is to provide a panel manufacturing method capable of preventing defects.

本発明は、一端部に注入口が設けられ前記注入口から液状体が注入された複数のパネルの間に、350μN/cm以下の表面張力を有する板状体を介在させて前記複数のパネルを重ね合わせ、これら重ね合わせた前記複数のパネルを厚さ方向に向けて加圧し、この重ね合わせた前記複数のパネルを加圧した状態で、前記複数のパネルの前記注入口に封止材を塗布して、前記注入口を封止するものである。   According to the present invention, the plurality of panels are provided by interposing a plate-like body having a surface tension of 350 μN / cm or less between a plurality of panels in which an inlet is provided at one end and a liquid material is injected from the inlet. Overlay, pressurize the plurality of overlapped panels in the thickness direction, and apply the sealing material to the inlets of the plurality of panels in a state where the overlapped panels are pressed Then, the inlet is sealed.

そして、注入口から液状体が注入された複数のパネルの間に、350μN/cm以下の表面張力を有する板状体を介在させて重ね合わせてから、パネルの厚さ方向に向けて加圧した状態で、複数のパネルそれぞれの注入口に封止材を塗布して、これらパネルそれぞれの注入口を封止する。   Then, a plate-like body having a surface tension of 350 μN / cm or less is interposed between the plurality of panels in which the liquid material is injected from the injection port, and then the pressure is applied in the thickness direction of the panel. In this state, a sealing material is applied to the inlets of the plurality of panels, and the inlets of the panels are sealed.

本発明によれば、注入口から液状体が注入された複数のパネルの間に、350μN/cm以下の表面張力を有する板状体を介在させて重ね合わせるので、これら重ね合わせたパネルを厚さ方向に加圧した状態で各注入口に封止材を塗布して封止することによって、これらパネルを板状体から外す際に、このパネルの注入口に塗布した封止材が板状体から容易に剥れるので、この封止材によるパネルの表面への付着が防止できるから、このパネルが不良となることを防止できる。   According to the present invention, since a plate-like body having a surface tension of 350 μN / cm or less is interposed between a plurality of panels into which a liquid material has been injected from an injection port, the stacked panels have a thickness. When the panel is removed from the plate-like body by applying a sealing material to each inlet in a state of being pressurized in the direction and sealed, the sealing material applied to the inlet of the panel is a plate-like body. Since it can be easily peeled off, adhesion of the sealing material to the surface of the panel can be prevented, so that this panel can be prevented from becoming defective.

以下、本発明の液晶パネルの第1の実施の形態の構成を図1を参照して説明する。   The configuration of the first embodiment of the liquid crystal panel of the present invention will be described below with reference to FIG.

図1において、1は液晶パネルで、この液晶パネル1は、液晶ディスプレイ(LCD:Liquid Crystal Display)としての液晶デバイスである。さらに、この液晶パネル1は、例えば0.4mm以上1.4mm以下の厚さ寸法に形成されている。そして、この液晶パネル1は、いわゆる低温ポリシリコン(Low Temperature Poly Silicon:LTPS)が用いられており、略矩形平板状のアレイ基板2を備えている。このアレイ基板2は、透光性を有する略透明な絶縁性基板である第1の基板としてのガラス基板3を有している。そして、このガラス基板3の一主面である表面の中央部には、カラー画像表示が可能な図示しない画像表示領域が設けられている。この画像表示領域には、複数の画素がマトリクス状に設けられている。   In FIG. 1, reference numeral 1 denotes a liquid crystal panel. The liquid crystal panel 1 is a liquid crystal device as a liquid crystal display (LCD). Further, the liquid crystal panel 1 is formed in a thickness dimension of, for example, 0.4 mm or more and 1.4 mm or less. The liquid crystal panel 1 uses so-called low temperature poly silicon (LTPS), and includes an array substrate 2 having a substantially rectangular flat plate shape. The array substrate 2 has a glass substrate 3 as a first substrate which is a substantially transparent insulating substrate having translucency. An image display area (not shown) capable of displaying a color image is provided at the center of the surface that is one main surface of the glass substrate 3. In the image display area, a plurality of pixels are provided in a matrix.

さらに、アレイ基板に対向して対向基板6が取り付けられている。この対向基板6は、略透明な透光性を有する絶縁性基板としてのガラス基板7を備えている。そして、このガラス基板7は、このガラス基板7一主面である表面をアレイ基板2のガラス基板3の表面に対向させて取り付けられており、これらガラス基板3,7の間に画像表示領域が設けられている。さらに、これらガラス基板3,7間には、これらガラス基板3,7間の画像表示領域を覆うように矩形枠状のシール材8が塗布されている。すなわち、これらガラス基板3,7は、シール材8を介して所定の間隙を介して貼り合わされている。   Further, a counter substrate 6 is attached to face the array substrate. The counter substrate 6 includes a glass substrate 7 as an insulating substrate having a substantially transparent translucency. The glass substrate 7 is attached with the surface which is one main surface of the glass substrate 7 facing the surface of the glass substrate 3 of the array substrate 2, and an image display area is provided between the glass substrates 3 and 7. Is provided. Further, a rectangular frame-shaped sealing material 8 is applied between the glass substrates 3 and 7 so as to cover the image display area between the glass substrates 3 and 7. That is, these glass substrates 3 and 7 are bonded to each other with a predetermined gap through the sealing material 8.

そして、これらガラス基板3,7の間には、所定の間隙として液晶封止領域11が設けられている。さらに、これらガラス基板3,7間のシール材8には、これらガラス基板3,7間の液晶封止領域11に液状体である液晶12が注入可能な液晶注入口13が設けられている。この液晶注入口13は、ガラス基板3,7間にシール材8を塗布しない部分を設けることによって形成されている。また、この液晶注入口13は、ガラス基板3,7の長手方向の一端側である封止材塗布辺15の幅方向の中央部に設けられている。   A liquid crystal sealing region 11 is provided as a predetermined gap between the glass substrates 3 and 7. Further, the sealing material 8 between the glass substrates 3 and 7 is provided with a liquid crystal injection port 13 through which a liquid crystal 12 which is a liquid material can be injected into a liquid crystal sealing region 11 between the glass substrates 3 and 7. The liquid crystal injection port 13 is formed by providing a portion where the sealing material 8 is not applied between the glass substrates 3 and 7. The liquid crystal injection port 13 is provided at the center in the width direction of the sealing material application side 15 which is one end side in the longitudinal direction of the glass substrates 3 and 7.

さらに、この液晶注入口13には、ガラス基板3,7間に液晶12を注入した状態で、封止剤としての封止材14が塗布されて、この封止材14が紫外線(UV)照射によって硬化されて、この封止材14にて液晶注入口13が封口される。ここで、この封止材14は、例えばエポキシフィルムを主成分とした合成樹脂にて構成されている。   Further, a sealing material 14 as a sealing agent is applied to the liquid crystal injection port 13 in a state where the liquid crystal 12 is injected between the glass substrates 3 and 7, and the sealing material 14 is irradiated with ultraviolet rays (UV). The liquid crystal injection port 13 is sealed with the sealing material 14. Here, the sealing material 14 is made of, for example, a synthetic resin mainly composed of an epoxy film.

次に、上記第1の実施の形態の液晶パネルの製造装置について説明する。   Next, the liquid crystal panel manufacturing apparatus of the first embodiment will be described.

図1において、21は液晶パネルの製造装置としての加圧封止装置であって、この加圧封止装置21は、矩形平板状の一対の加圧プレート22,23を備えている。これら加圧プレート22,23は、水平に対向させた状態で設置されている。そして、これら加圧プレート22,23間には、複数の液晶パネル1の間のそれぞれに離型性に優れた板状体としての緩衝材である離型フィルム24が介在されて、これら液晶パネル1が重ね合わされた液晶パネル群25が挿入される。   In FIG. 1, reference numeral 21 denotes a pressure sealing device as a liquid crystal panel manufacturing device, and this pressure sealing device 21 includes a pair of pressure plates 22 and 23 having a rectangular flat plate shape. These pressure plates 22 and 23 are installed in a state of facing horizontally. Between the pressure plates 22 and 23, a release film 24, which is a buffer material as a plate-like body having excellent releasability, is interposed between the plurality of liquid crystal panels 1, respectively. A liquid crystal panel group 25 in which 1 is superimposed is inserted.

すなわち、この液晶パネル群25は、液晶パネル1と離型フィルム24とが交互に重ね合わされて構成されている。さらに、この液晶パネル群25と加圧プレート22,23との間にも離型フィルム24が挟み込まれて介在されている。また、一対の加圧プレート22,23は、液晶パネル群25が挿入された状態で、図示しないシリンダなどにて液晶パネル群25を各液晶パネル1の厚さ方向に沿って加圧して、これら液晶パネル1それぞれのセルギャップGを均一にさせる。   That is, the liquid crystal panel group 25 is configured by alternately overlapping the liquid crystal panel 1 and the release film 24. Further, a release film 24 is also interposed between the liquid crystal panel group 25 and the pressure plates 22 and 23. The pair of pressure plates 22 and 23 press the liquid crystal panel group 25 along the thickness direction of each liquid crystal panel 1 with a cylinder or the like (not shown) while the liquid crystal panel group 25 is inserted. The cell gap G of each liquid crystal panel 1 is made uniform.

ここで、離型フィルム24は、封止材14に対する離型性に優れた素材、例えばフッ素系フィルム、ポリフッ化ビニルフィルム(テドラー:米国デュポン社製)、ポリメチルペンテンフィルム(TPX:三井化学株式会社製)、テフロン(登録商標)(米国デュポン社製)などにて構成された離型材である。さらに、この離型フィルム24は、この離型フィルム24の長手方向が液晶パネル1の長手方向より大きく、この離型フィルム24の幅方向が液晶パネル1の幅方向より大きい、矩形フィルム状に形成されている。   Here, the release film 24 is a material excellent in releasability with respect to the sealing material 14, such as a fluorine-based film, a polyvinyl fluoride film (Tedlar: manufactured by DuPont, USA), a polymethylpentene film (TPX: Mitsui Chemicals, Inc.). A mold release material composed of Teflon (registered trademark) (manufactured by DuPont, USA) and the like. Further, the release film 24 is formed in a rectangular film shape in which the longitudinal direction of the release film 24 is larger than the longitudinal direction of the liquid crystal panel 1 and the width direction of the release film 24 is larger than the width direction of the liquid crystal panel 1. Has been.

また、この離型フィルム24は、例えば0.2mm以上1.0mm以下の厚さ寸法を有しており、一対の加圧プレート22,23による加圧時に液晶パネル1が均等に潰れるとともに、これら液晶パネル1に損傷を与えない程度の弾性を有し、かつ封止材14に対する撥水性および離型性に優れている。   Further, the release film 24 has a thickness dimension of, for example, 0.2 mm or more and 1.0 mm or less, and the liquid crystal panel 1 is uniformly crushed when pressed by the pair of pressure plates 22 and 23. It has elasticity that does not damage the liquid crystal panel 1 and is excellent in water repellency and releasability with respect to the sealing material 14.

さらに、この離型フィルム24は、図2に示すように、封止材14と離型フィルム24との離型性テストの結果から、好ましくは特性として350μN/cm(=35dyne/cm)以下、より好ましくは250μN/cm以下の表面張力を有し、封止材14との離型性を確保するものである。なお、封止材14の垂れは、液晶パネル1の厚さが薄くなるにしたがって多くなり、特に、液晶パネル1の厚さ(t)が0.6mm以下では、封止材14の垂れを防止することが容易でなく、かつカッタなどによる除去では、液晶パネル1を破損させてしまうおそれがある。   Further, as shown in FIG. 2, the release film 24 is preferably 350 μN / cm (= 35 dyne / cm) or less as a characteristic from the result of the releasability test between the sealing material 14 and the release film 24. More preferably, it has a surface tension of 250 μN / cm or less and ensures releasability from the sealing material 14. The sagging of the sealing material 14 increases as the thickness of the liquid crystal panel 1 decreases. In particular, when the thickness (t) of the liquid crystal panel 1 is 0.6 mm or less, the sagging material 14 is prevented from sagging. It is not easy to do this, and removal with a cutter or the like may damage the liquid crystal panel 1.

そして、この離型フィルム24は、この離型フィルム24の長手方向の一端部を、液晶パネル1の液晶注入口13が位置している一端縁である封止材塗布辺15よりも、この液晶パネル1の液晶注入口13に塗布される封止材14の高さ寸法より高く突出して飛び出すように、これら液晶パネル1間に挟み込まれて取り付けられている。すなわち、この離型フィルム24は、液晶パネル1の封止材塗布辺15よりも飛び出させることによって、この液晶パネル1の液晶注入口13に塗布される封止材14の垂れなどを防止するガイドとなる。   The release film 24 has one end portion in the longitudinal direction of the release film 24 that is closer to the liquid crystal panel 1 than the sealing material application side 15 that is one end edge where the liquid crystal inlet 13 is located. The liquid crystal panel 1 is sandwiched and attached so as to protrude and protrude higher than the height of the sealing material 14 applied to the liquid crystal inlet 13 of the panel 1. That is, the release film 24 protrudes from the sealing material application side 15 of the liquid crystal panel 1 to prevent the sealing material 14 applied to the liquid crystal inlet 13 of the liquid crystal panel 1 from dripping. It becomes.

具体的に、この離型フィルム24は、液晶パネル1の液晶注入口13に塗布される封止材14の高さ寸法が1mm以下であるので、この離型フィルム24の液晶パネル1の封止材塗布辺15からの突出量Aが1mm以上となるように、液晶パネル1間に挿入されて挟み込まれている。   Specifically, since the release film 24 has a height dimension of the sealing material 14 applied to the liquid crystal inlet 13 of the liquid crystal panel 1 of 1 mm or less, the release film 24 is sealed with the liquid crystal panel 1. It is inserted and sandwiched between the liquid crystal panels 1 so that the protruding amount A from the material application side 15 is 1 mm or more.

さらに、一対の加圧プレート22,23にて液晶パネル群25の液晶パネル1それぞれのセルギャップGが均一になるまで加圧された各液晶パネル1の液晶注入口13には、塗布手段としてのディスペンサ26にて封止材14が塗布される。この封止材14は、各液晶パネル1の液晶注入口13に塗布された状態での高さ寸法が1mm以下となる。そして、この封止材14が塗布されて紫外線照射にて硬化されて液晶パネル1の液晶注入口13が封止された状態で、一対の加圧プレート22,23による加圧が解除されて、これら一対の加圧プレート22,23によって加圧されていた液晶パネル群25の各液晶パネル1のそれぞれが離型フィルム24間から離型されて取り外される。   Further, the liquid crystal injection port 13 of each liquid crystal panel 1 pressurized by the pair of pressure plates 22 and 23 until the cell gap G of each liquid crystal panel 1 of the liquid crystal panel group 25 becomes uniform is applied as a coating means. The sealing material 14 is applied by the dispenser 26. The sealing material 14 has a height dimension of 1 mm or less when applied to the liquid crystal injection port 13 of each liquid crystal panel 1. Then, in a state where the sealing material 14 is applied and cured by ultraviolet irradiation and the liquid crystal inlet 13 of the liquid crystal panel 1 is sealed, the pressure applied by the pair of pressure plates 22 and 23 is released, Each of the liquid crystal panels 1 of the liquid crystal panel group 25 that has been pressurized by the pair of pressure plates 22 and 23 is released from between the release films 24 and removed.

次に、上記第1の実施の形態の液晶パネルの製造方法について説明する。   Next, a method for manufacturing the liquid crystal panel of the first embodiment will be described.

まず、複数、例えば4枚の液晶パネル1それぞれの液晶注入口13から液晶12を注入させる。   First, the liquid crystal 12 is injected from the liquid crystal injection port 13 of each of a plurality of, for example, four liquid crystal panels 1.

次いで、これら液晶12が注入された液晶パネル1それぞれの封止材塗布辺15を上側に向けた状態で、これら液晶パネル1それぞれの封止材塗布辺15よりも離型フィルム24の一端部を突出させた状態で、これら離型フィルム24を液晶パネル1間に介在させて液晶パネル群25とする。   Next, in a state where the sealing material application side 15 of each of the liquid crystal panels 1 into which the liquid crystal 12 has been injected is directed upward, the one end portion of the release film 24 is positioned more than the sealing material application side 15 of each of the liquid crystal panels 1. In the protruding state, these release films 24 are interposed between the liquid crystal panels 1 to form a liquid crystal panel group 25.

この後、この液晶パネル群25を加圧封止装置21の一対の加圧プレート22,23間に挿入して介在させる。このとき、これら一対の加圧プレート22,23と液晶パネル群25の最も外側に位置する液晶パネル1との間にも、この液晶パネル1の封止材塗布辺15よりも一端部を突出させた状態で離型フィルム24を介在させる。   Thereafter, the liquid crystal panel group 25 is inserted and interposed between the pair of pressure plates 22 and 23 of the pressure sealing device 21. At this time, one end of the pair of pressure plates 22 and 23 and the liquid crystal panel 1 located on the outermost side of the liquid crystal panel group 25 is protruded from the sealing material application side 15 of the liquid crystal panel 1. In this state, the release film 24 is interposed.

次いで、一対の加圧プレート22,23のそれぞれをシリンダにて加圧して、これら一対の加圧プレート22,23にて液晶パネル群25の各液晶パネル1それぞれのセルギャップGが均一になるまで加圧して潰す。   Next, each of the pair of pressure plates 22 and 23 is pressurized by a cylinder until the cell gap G of each liquid crystal panel 1 of the liquid crystal panel group 25 becomes uniform with the pair of pressure plates 22 and 23. Press to crush.

この状態で、液晶パネル群25の各液晶パネル1の液晶注入口13に、封止材14をディスペンサにて塗布して封止する。   In this state, a sealing material 14 is applied and sealed to the liquid crystal inlet 13 of each liquid crystal panel 1 of the liquid crystal panel group 25 by a dispenser.

この後、これら液晶パネル1の液晶注入口13に塗布した封止材14に紫外線を照射させて、これら封止材14を硬化させて液晶注入口13を液密に封口する。   Thereafter, the sealing material 14 applied to the liquid crystal injection port 13 of the liquid crystal panel 1 is irradiated with ultraviolet rays to cure the sealing material 14 and seal the liquid crystal injection port 13 in a liquid-tight manner.

次いで、一対の加圧プレート22,23による液晶パネル群25の加圧を解除させ、これら一対の加圧プレート22,23間から液晶パネル群25を取り出して、この液晶パネル群25の各液晶パネル1から離型フィルム24を取り外して、液晶注入口13が封止材14にて封止された液晶パネル1とする。   Next, the pressure applied to the liquid crystal panel group 25 by the pair of pressure plates 22 and 23 is released, the liquid crystal panel group 25 is taken out between the pair of pressure plates 22 and 23, and each liquid crystal panel of the liquid crystal panel group 25 is removed. The release film 24 is removed from the liquid crystal panel 1, and the liquid crystal injection port 13 is sealed with a sealing material 14.

上述したように、上記一実施の形態によれば、液晶注入口13から液晶12が注入された複数の液晶パネル1の間に、350μN/cm以下の表面張力を有する離型フィルム24を介在させて、これら液晶パネル1を重ね合わせて液晶パネル群25とし、この液晶パネル群25の厚さ方向に向けて一対の加圧プレート22,23にて各液晶パネル1を加圧した状態で、これら液晶パネル1それぞれの液晶注入口13に封止材14を塗布して、これら液晶パネル1それぞれの液晶注入口13を封止して、これら液晶パネル1を組み立てる構成とした。   As described above, according to the above embodiment, the release film 24 having a surface tension of 350 μN / cm or less is interposed between the plurality of liquid crystal panels 1 into which the liquid crystal 12 is injected from the liquid crystal injection port 13. The liquid crystal panels 1 are overlapped to form a liquid crystal panel group 25. In a state where the liquid crystal panels 1 are pressed by a pair of pressure plates 22 and 23 in the thickness direction of the liquid crystal panel group 25, The liquid crystal panel 1 is assembled by applying a sealing material 14 to the liquid crystal inlets 13 of the liquid crystal panels 1 and sealing the liquid crystal inlets 13 of the liquid crystal panels 1.

この結果、一対の加圧プレート22,23による加圧を解除して、液晶パネル群25の各液晶パネル1から離型フィルム24を取り外す際に、この離型フィルム24による封止材14に対する離型性が優れているので、これら液晶パネル1の液晶注入口13に塗布された封止材14を破損させたり液晶注入口13から剥れたりなどすることなく、これら液晶パネル1および封止材14から離型フィルム24を容易に剥がして取り外すことができる。   As a result, when the pressure applied by the pair of pressure plates 22 and 23 is released and the release film 24 is removed from each liquid crystal panel 1 of the liquid crystal panel group 25, the release film 24 releases the sealing material 14 from the liquid crystal panel 1. Since the moldability is excellent, the liquid crystal panel 1 and the sealing material can be used without damaging or peeling off the sealing material 14 applied to the liquid crystal inlet 13 of the liquid crystal panel 1. The release film 24 can be easily peeled off from 14 and removed.

よって、この離型フィルム24を剥がす際などに生じる、欠けた封止材14が液晶パネル1の表面などへの付着を防止できるから、この液晶パネル1の表面に貼り付けられる図示しない偏光板との間に封止材14が異物として入り込んで再付着するなどの不良の発生を防止できる。したがって、この封止材14の付着による液晶パネル1が不良になることを防止できる。   Therefore, since the chipping sealing material 14 generated when the release film 24 is peeled off can be prevented from adhering to the surface of the liquid crystal panel 1, a polarizing plate (not shown) attached to the surface of the liquid crystal panel 1 and It is possible to prevent the occurrence of defects such as the sealing material 14 entering as a foreign material and reattaching between them. Therefore, it is possible to prevent the liquid crystal panel 1 from being defective due to the adhesion of the sealing material 14.

さらに、複数の液晶パネル1間に離型フィルム24を介在させる際に、この離型フィルム24の一端部を液晶パネル1の封止材塗布辺15よりも飛び出させて突出させる構成とした。この結果、これら液晶パネル1の封止材塗布辺15に封止材14を塗布した際に、これら液晶パネル1の封止材塗布辺15よりも突出している離型フィルム24の一端部がガイドとなり、これら液晶パネル1の封止材塗布辺15に塗布した封止材14による液晶パネル1表面への垂れを防止できる。   Further, when the release film 24 is interposed between the plurality of liquid crystal panels 1, one end portion of the release film 24 protrudes from the sealing material application side 15 of the liquid crystal panel 1 and protrudes. As a result, when the sealing material 14 is applied to the sealing material application side 15 of the liquid crystal panel 1, one end portion of the release film 24 protruding from the sealing material application side 15 of the liquid crystal panel 1 is guided. Thus, it is possible to prevent the sealing material 14 applied to the sealing material application side 15 of the liquid crystal panel 1 from dripping onto the surface of the liquid crystal panel 1.

したがって、この封止材14が垂れて液晶パネル1の表面に付着することなく、この封止材14を液晶パネル1の封止材塗布辺15に塗布でき、これら液晶パネル1の液晶注入口13を封止できる。よって、液晶パネル1の表面に封止材14が垂れた場合などに必要な、この封止材14を液晶パネル1の表面から除去する作業を不要にできるから、この液晶パネル1の製造性を向上できる。   Therefore, the sealing material 14 can be applied to the sealing material application side 15 of the liquid crystal panel 1 without the sealing material 14 hanging down and adhering to the surface of the liquid crystal panel 1. Can be sealed. Therefore, the work of removing the sealing material 14 from the surface of the liquid crystal panel 1 that is necessary when the sealing material 14 hangs down on the surface of the liquid crystal panel 1 can be made unnecessary. It can be improved.

なお、上記第1の実施の形態では、離型性に優れた一枚の離型フィルム24を緩衝材として液晶パネル1間に介在させたが、図3に示す第2の実施の形態のように、例えばゴムあるいはスポンジなどの弾性を有する矩形板状の弾性材31の両側面に離型フィルム24をそれぞれ貼り付けた板状体としての緩衝材32を液晶パネル1間に介在させたり、図4に示す第3の実施の形態のように、弾性材31の上端部を覆うように、この弾性材31の一側面から他側面に亘って離型フィルム24を貼り付けた緩衝材32を液晶パネル1間に介在させたりしても、上記第1の実施の形態と同様の作用効果を奏することができる。   In the first embodiment, a single release film 24 excellent in releasability is interposed between the liquid crystal panels 1 as a buffer material. However, as in the second embodiment shown in FIG. Further, for example, a cushioning material 32 as a plate-like body in which release films 24 are attached to both sides of a rectangular plate-like elastic material 31 having elasticity, such as rubber or sponge, is interposed between the liquid crystal panels 1. As in the third embodiment shown in FIG. 4, the cushioning material 32 with the release film 24 pasted from one side surface to the other side surface of the elastic material 31 is covered with liquid crystal so as to cover the upper end of the elastic material 31. Even if it is interposed between the panels 1, the same effects as those of the first embodiment can be obtained.

さらに、上記第1の実施の形態では、ディスペンサ26を用いて液晶パネル1それぞれの液晶注入口13に封止材14を塗布したが、この封止材14を図示しないローラや刷毛塗りなどで各液晶パネル1それぞれの液晶注入口13に塗布することもできる。   Further, in the first embodiment, the sealing material 14 is applied to the liquid crystal inlets 13 of the liquid crystal panel 1 using the dispenser 26. The sealing material 14 is applied to each of the liquid crystal panels 1 by a roller or brush not shown. It can also apply | coat to the liquid-crystal injection hole 13 of each liquid crystal panel 1. FIG.
