Description

【0001】
【発明の属する技術分野】
本発明は、透明基板の内面に遮光膜を有する液晶表示装置およびその製造方法に関する。
【0002】
【従来の技術】
従来、液晶表示装置は、液晶表示パネルに入射する光を完全に制御するために、パネル有効画素外周隣接部となるところに遮光膜を形成したカバーガラスを備える(例えば、特許文献1を参照。)。遮光膜は、カバーガラスの製造時に塗料を用いて印刷される。遮光膜が形成されたカバーガラスは、二液形シリコーン樹脂を用いて液晶表示パネル表面に貼り付けられる。
【0003】
図5は液晶表示パネルとカバーガラスの接着工程を示している。
第1工程:対向ガラス11とTFT(Thin Film Transistor)基板12を貼り合わせた液晶表示パネル10に、フレキシブル基板13を取り付ける(図5(a))。
第2工程:液晶表示パネル10に二液形シリコーン樹脂14を滴下する(図5(b))。これを液晶表示パネル10の両面について行う。
第3工程:二液形シリコーン樹脂14の上に、遮光膜15を形成したカバーガラス1を貼り付ける(図5(c))。
第4工程:オートクレーブ(以下、「AC(Autoclave)」と称す。)内で熱と圧力を加えて二液形シリコーン樹脂14を硬化させる(図5(d))。
【0004】
上記第2工程において二液形シリコーン樹脂14を滴下する際にエアが噛み込む。また、上記第3工程においてカバーガラス1を貼り付ける際に入り込んだエアがエア溜まりとなり気泡が発生する。上記第4工程は、この気泡を完全に排除するためにACに投入し、圧力を掛けてエア抜きを行うものである。
【0005】
図6はカバーガラス1に形成された遮光膜15の例を示す図であって、(a)は平面図、(b)は(a)のG−G’断面図である。図6に示すように、遮光膜15は、約10μmの厚さでカバーガラス1の周縁部を周回するように形成されている。
【0006】
【特許文献1】
特開平10−232629号公報
【0007】
【発明が解決しようとする課題】
エア噛み込みによる気泡は、遮光膜15の厚みよりも小さい個体により存在する。ところが、カバーガラス1周縁部に形成された遮光膜15の内側で気泡同士が合体すると、一個体で数μmの気泡が数十μmの帯状形の気泡に拡大される。
【0008】
これにより遮光膜15の内側に溜まった気泡4は排出される道がなくなり、図7に示すように、パネル有効画素外周隣接部に固定化される。このように気泡4が固定化された液晶表示装置は製造不良となるため、液晶表示装置の製造工程に悪影響を及ぼすことになる。
【0009】
また、このような液晶表示装置は、液晶プロジェクタなどに実装され、使用された際に、70℃程度の温度まで上昇することがある。二液形シリコーン樹脂の場合、樹脂内に気泡が存在すると、この温度上昇によって気泡同士が繋がって拡大し、製品不良の原因となることがある。
【0010】
そこで、本発明においては、遮光膜の内側に気泡が溜まるのを防止した液晶表示装置およびその製造方法を提供することを目的とする。
【0011】
【課題を解決するための手段】
本発明の液晶表示装置は、遮光膜を形成した透明基板を液晶表示パネルの表面に接着樹脂により貼り付けた液晶表示装置において、遮光膜に、接着樹脂中の気泡を排出するためのエア抜き部を備えたことを特徴とするものである。
【0012】
本発明の液晶表示装置では、液晶表示装置の製造工程中に、接着樹脂中に入り込んだ気泡が、遮光膜に備えたエア抜き部から外部へと効率良く排出される。
【0013】
本発明の液晶表示装置の製造方法は、遮光膜を形成した透明基板を液晶表示パネルの表面に接着樹脂により貼り付ける液晶表示装置の製造方法において、透明基板に、接着樹脂中の気泡を排出するためのエア抜き部を設けた遮光膜を形成し、液晶表示パネルの表面に、接着樹脂を用いて透明基板を貼り付け、オートクレーブ内で熱と圧力を加えて接着樹脂を硬化させることを特徴とする。
【0014】
本発明の液晶表示装置の製造方法によれば、液晶表示パネルの表面に透明基板を貼り付ける際に接着樹脂中に入り込んだ気泡が、オートクレーブ内で熱と圧力を加えられることにより遮光膜のエア抜き部から外部へと効率良く排出された状態で、接着樹脂が硬化する。
【0015】
【発明の実施の形態】
(実施の形態1)
図1は本発明の第1実施形態における液晶表示装置のカバーガラスに形成された遮光膜を示す図であって、(a)は平面図、(b)は(a)のA−A’断面図、(c)は(b)のB部詳細図である。
【0016】
図1に示すように、本発明の第1実施形態における液晶表示装置では、透明基板としてのカバーガラス1に形成する遮光膜2に、エア抜き部として傾斜面3を形成している。遮光膜2は、カバーガラス1の周縁部、すなわちパネル有効画素外周隣接部を周回するように連続的に形成している。傾斜面3は、この遮光膜2によって囲まれた部分の内側のカバーガラス1表面から外側に向かって20〜40°の角度で形成している。
【0017】
本発明の第1実施形態における液晶表示装置は、遮光膜2以外の構造については従来と同様であり、図5で説明したのと同様の手順により製造するが、AC内での状態の遷移が異なる。図2は図1の遮光膜2を形成したカバーガラス1を液晶表示パネル10に貼り付け、AC内で熱と圧力を加えた状態を示す断面図である。
【0018】
図2に示すように、液晶表示パネル10の対向ガラス11とTFT基板12のそれぞれの表面に接着樹脂としての二液形シリコーン樹脂14を滴下し、図1に示す遮光膜2を形成したカバーガラス1を貼り付け、AC内で熱と圧力を加える。
【0019】
このとき、二液形シリコーン樹脂14を滴下する際に噛み込んだエアやカバーガラス1を貼り付ける際に入り込んだエアによる気泡4は、遮光膜2に形成された傾斜面3によって遮光膜2の外側へ導かれ、二液形シリコーン樹脂14から外部へと排出される。そのため、二液形シリコーン樹脂14は、AC内で、内部の気泡4が外部に排出された状態で硬化する。これにより、遮光膜2の内部に気泡4の発生のない液晶表示装置が得られる。
【0020】
(実施の形態2)
図3は本発明の第2実施形態における液晶表示装置のカバーガラスに形成された遮光膜を示す図であって、(a)は平面図、(b)は(a)のC−C’断面図、(c)は(b)のD部詳細図である。
【0021】
図3に示すように、本発明の第2実施形態における液晶表示装置では、カバーガラス1に形成する遮光膜5に、エア抜き部として凹凸6を形成している。遮光膜5は、第1実施形態と同様、カバーガラス1の周縁部を周回するように連続的に形成している。凹凸6は、この遮光膜5の表面に段差が生じるように形成したものである。凹凸6の全体の厚さは従来と同様の約10μmで、最厚部と最薄部で約5μmの段差を設けている。
【0022】
このような凹凸6を有する遮光膜5は、例えば、通常の遮光膜の形成工程(印刷・乾燥・洗浄)を2回行うことにより形成することが可能である。より具体的には、最薄部となる1段目の遮光膜5a(カバーガラス1の周縁部を周回する連続的な遮光膜)を形成した後、最厚部となる2段目の遮光膜5b(カバーガラス1の周縁部を周回するが、不連続な遮光膜)を形成する。
【0023】
このように遮光膜5に凹凸6を設けた液晶表示装置では、二液形シリコーン樹脂14中の気泡4が、遮光膜5に形成された凹凸6の最薄部から遮光膜5の外側へ導かれ、外部へと排出される。これにより、二液形シリコーン樹脂14は、AC内で、内部の気泡4が外部に排出された状態で硬化し、遮光膜5の内部に気泡4の発生のない液晶表示装置が得られる。
【0024】
(実施の形態3)
図4は本発明の第3実施形態における液晶表示装置のカバーガラスに形成された遮光膜を示す図であって、(a)は平面図、(b)は(a)のE−E’断面図、(c)は(b)のF部詳細図である。
【0025】
図4に示すように、本発明の第3実施形態における液晶表示装置では、カバーガラス1に形成する遮光膜7に、エア抜き部としてスリット8を形成している。遮光膜7は、カバーガラス1の周縁部を周回するように形成しているが、一部スリット8によって不連続となっている。遮光膜7の厚さは従来と同様の約10μmで、スリット8の幅は約50μmである。このような遮光膜7は、印刷時にスリット8となる部分に膜が印刷されないようにして形成する。
【0026】
このように遮光膜7にスリット8を設けた液晶表示装置では、二液形シリコーン樹脂14中の気泡4が、スリット8から遮光膜7の外側へ導かれ、外部へと排出される。これにより、二液形シリコーン樹脂14は、AC内で、内部の気泡4が外部に排出された状態で硬化し、遮光膜7の内部に気泡4の発生のない液晶表示装置が得られる。
【0027】
また、第3実施形態における液晶表示装置では、遮光膜7のスリット8の部分によって、カバーガラス1と液晶表示パネル10とが遮光膜7を介さずに二液形シリコーン樹脂14によって直接接着される。これにより、カバーガラス1と液晶表示パネル10との密着性が向上し、二液形シリコーン樹脂14の温度上昇に伴う気泡4の拡大などの不良の発生が防止される。
【0028】
【発明の効果】
本発明では、遮光膜に、接着樹脂中の気泡を排出するためのエア抜き部を備えたことによって、液晶表示装置の製造工程中に、接着樹脂中に入り込んだ気泡が、遮光膜に備えたエア抜き部から外部へと効率良く排出されるため、遮光膜の内部に気泡の発生のない液晶表示装置が得られる。

The light-shielding film is printed using a paint when manufacturing the cover glass. The cover glass on which the light-shielding film is formed is attached to the surface of the liquid crystal display panel using a two-part silicone resin.

FIG. 5 shows a bonding step between the liquid crystal display panel and the cover glass.
First step: A flexible substrate 13 is attached to a liquid crystal display panel 10 in which an opposite glass 11 and a TFT (Thin Film Transistor) substrate 12 are bonded (FIG. 5A).
Second step: The two-component silicone resin 14 is dropped on the liquid crystal display panel 10 (FIG. 5B). This is performed on both sides of the liquid crystal display panel 10.
Third step: The cover glass 1 on which the light shielding film 15 is formed is attached on the two-liquid type silicone resin 14 (FIG. 5C).
Fourth step: Two-part silicone resin 14 is cured by applying heat and pressure in an autoclave (hereinafter, referred to as “AC (Autoclave)”) (FIG. 5D).
[0004]
When the two-part silicone resin 14 is dropped in the second step, air is caught. In addition, in the third step, air that has entered when the cover glass 1 is attached becomes an air pool, and air bubbles are generated. In the fourth step, the bubbles are charged into AC to completely eliminate the bubbles, and air is released by applying pressure.
