Description
本出願は、日本国において2009年10月13日に出願された日本特許出願番号特願2009-236520を基礎として優先権を主張するものであり、この出願を参照することにより、本出願に援用される。

1-2.装置動作
1-3.他の描画パターン
1-4.他の装置構成
2.透明樹脂充填剤
3.実施例
本発明の具体例として示す表示装置の製造方法は、画像表示パネルと表面パネルとを所定の間隔に配置するとともに、透明樹脂充填剤を吐出供給するための供給手段を画像表示パネルと表面パネルとの間に挿入し、透明樹脂充填剤を供給手段から供給する。そして、画像表示パネル又は前記表面パネルを押圧して、透明樹脂充填剤を両パネル間に充填させ、透明樹脂充填剤を硬化処理させて透明樹脂充填層を形成する。供給手段を用いて透明樹脂充填剤を供給する際、透明樹脂充填剤が画像表示パネルと表面パネルの両パネルに接触するように透明樹脂充填剤を供給手段から吐出供給して所定の形状を描画し、所定の形状の描画が終了するまで透明樹脂充填剤が両パネルに接触した状態を維持させる。これにより、小型の表示装置は勿論、大型の表示装置であっても透明樹脂充填剤の中に気泡が残存することを防止できる。
次に、表示装置の製造方法において好適に用いられる透明樹脂充填剤の充填装置について説明する。
次いで、図5及び図6を参照しながら充填装置1の動作について説明する。なお、本実施の形態では、矩形状の液晶パネル2及び保護パネル3の間隙に接着剤7を充填する場合について説明するが、液晶パネル2及び保護パネル3の形状は矩形に限られない。
充填装置1によって描画されるパターンは、図6Dに示すパターンに限られず、液晶パネル2及び保護パネル3の大きさや接着剤7の粘度等に応じて、気泡が混入されず、所定時間で隅々まで充填されるパターンが選択される。例えば、図7に示す描画パターンP2は、略矩形状の液晶パネル2及び保護パネル3の長手方向に沿って延長する幹線部33と、幹線部33の両端部から四隅に向かう斜線部34と、幹線部33から液晶パネル2及び保護パネル3の短手方向に延びる枝線部35とを有する。
ノズル移動機構11は、吐出ノズル10を複数備え、液晶パネル2及び保護パネル3の相対向する辺から間隙に挿入するようにしてもよい。液晶パネル2及び保護パネル3が大型化し、例えば、12インチ以上の液晶テレビに相当する大きさを備える場合などは、図8に示すように、吐出ノズル10を相対向する両面側に吐出ノズル10及びノズル移動機構11を備え、同時に接着剤7を塗布していくことで、接着剤7の塗布に要する時間を短縮することができる。
本実施の形態に係る透明樹脂充填剤は、上述したように画像表示パネルと表面パネルの両パネルに挿入される供給手段が所定の形状の描画を終了するまで両パネルに接触した状態を維持する。このような透明樹脂充填剤は、粘度が800~3500mPa・sの範囲のものである。これにより、画像表示パネルと表面パネルとの間隔が2.5~5.5mmの範囲であっても、供給手段を両パネルに接触させた状態を維持させることができる。
以下、実施例を挙げて、本発明を具体的に説明する。この実施例では、透明樹脂充填剤の粘度と両パネルにおけるGap量との関係を検証した。なお、本発明はこれらの実施例に限定されるものではない。
