Description

端子接続構造及び表示装置
　本発明は、並置形成されている複数の第１端子を含む第１端子列、及び、複数の第１端子と接続する複数の第２端子を含み第１端子列と対向する第２端子列の端子接続構造に関する。
　近年、液晶表示パネルを用いた表示装置においては、より鮮明な画像を表示すべく、解像度の増加、すなわち、単位面積当たりの画素数の増加が進んでいる。このような、画素数の増加は斯かる接続端子の挟ピッチ化を伴うので、接続の位置ずれによるリーク不良の虞がある。
　これに対して、特許文献１においては、半導体チップ周縁部の所定の位置ずれ防止領域に、少なくとも１本の第２リード配線を配置し、又は、第２突起電極をリード配線に挟まれるように配置して、位置ずれ防止パターンを設置することにより、半導体チップの厚さ又は突起電極の高さのばらつきに起因して生じる第１リード配線と第１突起電極の接合位置ずれを低減し、リーク不良を回避しつつ、突起電極のファインピッチ化が容易な半導体装置が開示されている。
特開２０１３－２３９６５２号公報
　このような挟ピッチの問題に対しては、特許文献１のような方法以外にも、異方性導電膜（ＡＣＦ）粒子径の小型化による対応が行われてきた。
　一方、最近、いわゆる４Ｋ又は８Ｋと呼ばれる、高解像度の表示装置が普及されつつあり、このような表示装置においては、接続端子を更に狭くする必要があるので、接続の位置ずれによるリーク不良の虞が一層高まっている。しかしながら、上述した解決方法は既に技術的限界に達しており、対応できない。
　本発明は、斯かる事情に鑑みてなされたものであり、その目的とするところは、並置形成されている複数の第１端子を含む第１端子列、及び、複数の第１端子と接続する複数の第２端子を含み第１端子列と対向する第２端子列の端子接続構造において、より確実に接続が行われ、かつ接続の位置ずれによるリーク不良の発生を抑えることができる端子接続構造及び該端子接続構造を備えた表示装置を提供することにある。
　本発明に係る端子接続構造は、並置形成されている複数の第１端子を含む第１端子列、及び、前記複数の第１端子と接続する複数の第２端子を含み前記第１端子列と対向する第２端子列の端子接続構造において、前記第１端子列及び前記第２端子列の夫々では、隣合う２つの端子が対応する凹凸形状を有することを特徴とする。
　本発明に係る表示装置は、画像を表示する表示パネルと、前述の端子接続構造により接続される前記第１端子及び前記第２端子を介して信号を入力することで前記表示パネルを駆動する駆動部とを備えることを特徴とする。
　より確実に接続が行われ、かつ接続の位置ずれによるリーク不良の発生を抑えることができる端子接続構造及び該端子接続構造を備えた表示装置が提供される。

（実施の形態１）
  図１は実施の形態１に係るテレビジョン受像機の要部構成例を示す機能ブロック図である。
　本実施の形態に係るテレビジョン受像機１００は、略矩形の扁平な六面体であり、表側の一面に画像を表示する液晶パネルモジュール１と、チューナ（図示せず）で受信したカラー映像信号を、カラー映像に係る赤（Ｒ）、緑（Ｇ）及び青（Ｂ）を示す信号に変換するテレビ信号処理部７とを有する。
　また、液晶パネルモジュール１は、赤（Ｒ）、緑（Ｇ）及び青（Ｂ）のカラーフィルタを有する液晶パネル１１と、液晶パネル１１を背面側から照明するバックライト１２と、テレビ信号処理部７により変換された赤、緑及び青のテレビ信号に従って液晶パネル１１を駆動してカラー映像を表示させる液晶駆動回路部１４（駆動部）とを有する。液晶駆動回路部１４は、信号電極駆動回路及び走査信号駆動回路などを有する。
  液晶パネル１１は、スペーサを介して対向配置された略長方形の２枚のガラス基板間、すなわち表側のカラーフィルタ基板と裏側のＴＦＴ基板との間に液晶を封入してなる。カラーフィルタ基板のＴＦＴ基板に対向する面には、カラーフィルタと、対向電極（図示せず）とが配されている。ＴＦＴ基板のカラーフィルタ基板に対向する面には、走査線及び信号線がマトリクス状に配されており、走査線と信号線との交差部分には、各画素に対応した液晶部分に電圧を印加するためのＴＦＴ（Thin Film Transistor）及び画素電極が設けられている。各ＴＦＴのゲート電極は走査線に接続され、ソース電極は信号線に接続されている。
　図２は実施の形態１に係るテレビジョン受像機１００の液晶パネル１１における、電気的接続を説明する部分断面図である。
　図２に示すように、ＴＦＴ基板１１１のカラーフィルタ基板１３に対向する面の縁部には、液晶パネル１１を駆動するための信号を受ける基板端子１１２（第１端子）が複数並置され、基板端子列（第１端子列）をなしている。液晶パネル１１は、基板端子１１２，…，１１２を介して、信号電極駆動回路又は走査信号駆動回路を搭載したＣＯＦ（Chip on Film）８から受ける信号に基づいて駆動される。
　ＣＯＦ８は、液晶パネル１１の駆動に係る信号をＴＦＴ基板１１１の基板端子１１２，…，１１２を介して液晶パネル１１に送信する。ＣＯＦ８には、ＴＦＴ基板１１１の基板端子１１２，…，１１２と接続するための接続端子８１（第２端子）が複数並置される。接続端子８１，…，８１は、基板端子１１２の基板端子列に対向するよう、接続端子列（第２端子列）を形成している。
　基板端子１１２，…，１１２を含む基板端子列と、接続端子８１，…，８１を含む接続端子列とは、本実施の形態に係る端子接続構造を構成する。なお、図２においては、基板端子列に含まれる一部の基板端子１１２の表示と接続端子列に含まれる一部の接続端子８１の表示とを省略している。
　各基板端子１１２が接続すべき各接続端子８１と夫々接続することにより、ＣＯＦ８とＴＦＴ基板１１１上の回路とが電気的に接続される。この際、基板端子１１２（基板端子列）と接続端子８１（接続端子列）との間には、異方性導電膜（ＡＣＦ）が介在し、基板端子１１２及び接続端子８１は、ＡＣＦの導電性粒子を介して電気的に接続される。
　図３は実施の形態１に係るテレビジョン受像機１００における、接続端子８１の形状の一例を示す例示図であり、図４は実施の形態１に係るテレビジョン受像機１００における、基板端子１１２の形状の一例を示す例示図である。
　接続端子８１は、図３に示すように、複数の接続端子８１が並置される方向（以下、接続端子列の並置方向という）において、隣合う２つの端子が対応する凹凸形状を有している。ここで、対応する凹凸形状とは、隣合う２つの端子のうちの一方の端子に凸部が設けられている場合に、他方の端子の当該凸部に対向する位置に、当該凸部と同等かそれ以上の面積の凹部が設けられている形状をいう。言い換えれば、隣合う２つの端子のうちの一方の端子に凹部が設けられている場合に、他方の端子の当該凹部に対向する位置に、当該凹部と同等かそれ以上の面積の凸部が設けられている形状をいう。接続端子列において、相互対向する凹凸形状を有する接続端子８１Ａ及び接続端子８１Ｂが交互に並置されている。
　例えば、接続端子８１Ａは、矩形の中間部８１１Ａと、中間部８１１Ａの長手方向の両端から、該長手方向に延設された短冊状の端部８１２Ａ，８１２Ａとを有している。本実施の形態では、中間部８１１Ａは、端部８１２Ａより、長手方向及び短手方向における寸法が大きく、端部８１２Ａは中間部８１１Ａの短辺の中央から斯かる長手方向に延設されている。従って、接続端子８１Ａの全体においては、相対的に、中間部８１１Ａが凸部となり、端部８１２Ａが凹部となる。
　また、例えば、接続端子８１Ｂは、短冊状の中間部８１１Ｂと、中間部８１１Ｂの長手方向の両端に延設された矩形の端部８１２Ｂ，８１２Ｂとを有している。本実施の形態では、中間部８１１Ｂはその長手方向における寸法が端部８１２Ｂより大きく、短手方向の寸法は端部８１２Ｂより小さい。また、各端部８１２Ｂの長辺側の中央に中間部８１１Ｂの両端が夫々連結されている。すなわち、中間部８１１Ｂ及び端部８１２Ｂは、中間部８１１Ｂの長手方向と、端部８１２Ｂの長手方向が交差するように連結されている。このような接続端子８１Ｂの全体においては、相対的に、端部８１２Ｂが凸部となり、中間部８１１Ｂが凹部となる。
　例えば、端子間ピッチをＰ（図３中、Ａ１及びＢ１間の距離）とすると、接続端子列の並置方向における中間部８１１Ａの短手方向の寸法及び端部８１２Ｂの長手方向の寸法は、共に０．５Ｐである。また、接続端子列の並置方向において、中間部８１１Ａと端部８１２Ａとの間には０．１５Ｐの段差が存在し、中間部８１１Ｂと端部８１２Ｂとの間にも０．１５Ｐの段差が存在する。なお、これらの寸法は一例であって、これらとは異なる寸法を設定してもよい。
　一方、基板端子１１２は、図４に示すように、複数の基板端子１１２が並置される方向（以下、基板端子列の並置方向という）において、隣合う２つの端子が対応する凹凸形状を有している。基板端子列において、相互対向する凹凸形状を有する基板端子１１２Ａ及び基板端子１１２Ｂが交互に並置されている。
　例えば、基板端子１１２Ａは、矩形の中間部１１２１Ａと、中間部１１２１Ａの長手方向の両端から、該長手方向に延設された矩形の端部１１２２Ａ，１１２２Ａとを有している。基板端子１１２Ａは、接続端子８１Ａと同様に、その全体においては、相対的に、中間部１１２１Ａが凸部となり、端部１１２２Ａが凹部となる。
　また、例えば、基板端子１１２Ｂは、短冊状の中間部１１２１Ｂと、中間部１１２１Ｂの長手方向の両端に延設された矩形の端部１１２２Ｂ，１１２２Ｂとを有している。基板端子１１２Ｂは、接続端子８１Ｂと同様に、その全体においては、相対的に、端部１１２２Ｂが凸部となり、中間部１１２１Ｂが凹部となる。
　例えば、端子間ピッチをＰ（図４中、Ａ２及びＢ２間の距離）とすると、基板端子列の並置方向における中間部１１２１Ａの短手方向の寸法及び端部１１２２Ｂの長手方向の寸法は、共に０．７Ｐである。また、基板端子列の並置方向において、中間部１１２１Ａと端部１１２２Ａとの間には０．１５Ｐの段差が存在し、中間部１１２１Ｂと端部１１２２Ｂとの間にも０．１５Ｐの段差が存在する。また、中間部１１２１Ａの長手方向に沿う方向における、端部１１２２Ａの寸法（図４中、Ｌ４と表示）と、中間部１１２１Ｂの長手方向に沿う方向における、端部１１２２Ｂの寸法（図４中、Ｌ４と表示）とは等しい。なお、これらの寸法は一例であって、これらとは異なる寸法を設定してもよい。
　本実施の形態において、接続端子８１及び基板端子１１２のそれぞれの端部８１２Ａ、８１２Ｂ、１１２２Ａ、１１２２Ｂの寸法は、以下の関係を有する。
　Ｌ２＝Ｌ４＋０．１Ｐ
　Ｌ３＝Ｌ４－０．１Ｐ　
　図３及び図４から分かるように、本実施の形態では、基板端子１１２Ａは、これに接続される接続端子８１Ａよりも大きく、基板端子１１２Ｂは、これに接続される接続端子８１Ｂよりも大きい。なお、基板端子１１２Ａと接続端子８１Ａとが、略同一の形状を有していてもよいし、相似形を有していてもよい。同様に、基板端子１１２Ｂと接続端子８１Ｂとが、略同一の形状を有していてもよいし、相似形を有していてもよい。また、接続端子８１Ａが基板端子１１２Ａよりも大きく、接続端子８１Ｂが基板端子１１２Ｂよりも大きくてもよい。
　また、図３及び図４から分かるように、本実施の形態において、接続端子８１Ａと接続端子８１Ｂは夫々接続端子列の並置方向にて線対称の形状を有しており、基板端子１１２Ａと基板端子１１２Ｂは夫々基板端子列の並置方向にて線対称の形状を有している。
　すなわち、接続端子８１Ａは、接続端子列の並置方向に直交する線であって接続端子８１Ａの当該並置方向の中間を通る基準線Ａ１の両側の形状が、該基準線Ａ１を軸として線対称の形状となっている。また、接続端子８１Ｂは、接続端子列の並置方向に直交する線であって接続端子８１Ｂの当該並置方向の中間を通る基準線Ｂ１の両側の形状が、該基準線Ｂ１を軸として線対称の形状となっている。
　このような線対称の形状は、基板端子１１２Ａは及び基板端子１１２Ｂにおいても同様である。すなわち、基板端子１１２Ａは、基板端子列の並置方向に直交する線であって基板端子１１２Ａの当該並置方向の中間を通る基準線Ａ２の両側の形状が、該基準線Ａ２を軸として線対称の形状となっている。また、基板端子１１２Ｂは、基板端子列の並置方向に直交する線であって基板端子１１２Ｂの当該並置方向の中間を通る基準線Ｂ２の両側の形状が、該基準線Ｂ２を軸として線対称の形状となっている。
　図５は実施の形態１に係るテレビジョン受像機１００において、接続端子８１と基板端子１１２との接続において位置ずれが発生していない場合を説明する説明図であり、図６は実施の形態１に係るテレビジョン受像機１００において、接続端子８１と基板端子１１２との接続において位置ずれが発生した場合を説明する説明図である。
　図５及び図６においては、並置された接続端子８１，…，８１からなるＣＯＦ８側の接続端子列８０と、並置された基板端子１１２，…，１１２からなるＴＦＴ基板１１１側の基板端子列１１０とを示している。なお、図５及び図６においては、便宜上、基板端子列１１０が４つの基板端子１１２によって構成され、接続端子列８０が４つの接続端子８１によって構成された場合を示しているが、基板端子列１１０を構成する基板端子１１２の数、及び接続端子列８０を構成する接続端子８１の数は、４つに限られない。
　図５に示すように、接続端子８１と基板端子１１２との接続において位置ずれが発生していない場合、ＴＦＴ基板１１１の厚み方向において、接続端子８１及び基板端子１１２が重畳し、接続端子８１が基板端子１１２に係る範囲内に位置される。この場合、接続端子８１と基板端子１１２とは正常に接続されている。
　例えば、図６に示したように、接続端子８１又は基板端子１１２の接続において、接続端子列８０の並置方向又は基板端子列１１０の並置方向（以下、単に端子の並置方向という）に位置ずれが発生する場合が生じ得る。これに対して、本実施の形態に係るテレビジョン受像機１００においては、接続端子列８０及び基板端子列１１０の夫々で隣合う２つの端子が対応する凹凸形状を有しているので、接続すべき端子間（例えば、接続端子８１Ａ及び基板端子１１２Ａ）の接続を維持した上で、接続してはいけない端子間（例えば、基板端子１１２Ａ及び接続端子８１Ｂ）の接続（リーク）が発生するまでの位置ずれの許容量（以下、位置ずれ許容量という）Ｘを出来るだけ大きくすることができる。
　ちなみに、接続端子及び基板端子が矩形形状である従来例に係る端子接続構造の場合は、次のようになる。すなわち、従来例に係る接続端子は、本実施の形態に係る接続端子８１と面積及び長手方向の長さが同じであれば、接続端子列の並置方向の長さが接続端子８１よりも短くなる。同様に、従来例に係る基板端子は、本実施の形態に係る基板端子１１２と面積及び長手方向の長さが同じであれば、基板端子列の並置方向の長さが基板端子１１２よりも短くなる。従って、従来例に係る端子接続構造の場合は、本実施の形態における位置ずれ許容量Ｘだけ位置ずれが起こると、接続すべき端子間の接続を維持できなくなってしまう。なお、接続端子及び基板端子の面積は、所定値以上であることが求められる。また、接続端子及び基板端子の長手方向の長さ（端子の並置方向に直交する方向の長さ）は、配置スペースの関係から所定位置以下であることが求められる。
　また、本実施の形態においては、端子の並置方向において、基板端子１１２の寸法が接続端子８１の寸法より大きいので、接続端子８１と基板端子１１２とが等しい寸法である場合に比べ、より確実に接続を行うことが出来る。
　以上においては、接続端子８１又は基板端子１１２の接続において、端子の並置方向に位置ずれが発生した場合を例に挙げて説明したが、端子の並置方向と交差する方向に位置ずれが発生した場合でも、接続すべき端子間の接続を維持した上で位置ずれ許容量を出来るだけ大きくするという上記と同様の効果が得られる。
（実施の形態２）
　実施の形態２において、テレビジョン受像機１００の構成、液晶パネル１１の構成、並びに、接続端子８１及び基板端子１１２の基本的な構成については、実施の形態１と同じである。以下、実施の形態１と異なる部分について説明する。
　図７は実施の形態２に係るテレビジョン受像機１００における、接続端子８１の形状の一例を示す例示図であり、図８は実施の形態２に係るテレビジョン受像機１００における、基板端子１１２の形状の一例を示す例示図である。
　図７に示すように、実施の形態２では、接続端子８１Ａの凸部である中間部８１１Ａと、接続端子８１Ｂの凸部である端部８１２Ｂとにおいて、凸部の角が湾曲している。
　また、図８に示すように、実施の形態２では、基板端子１１２Ａの凸部である中間部１１２１Ａと、基板端子１１２Ｂの凸部である端部１１２２Ｂとにおいて、凸部の角が湾曲している。
　本実施の形態においては、このように、接続端子８１と基板端子１１２とにおいて、凸部の角が湾曲しているので、接続してはいけない端子間の接続（リーク）の発生をより確実に防ぐことが出来る。
　以上、本発明の実施の形態を説明したが、本発明は、これらの実施の形態に限定されるものでなく、その要旨を逸脱しない範囲で種々変更可能である。  
　例えば、接続端子８１と基板端子１１２とにおいて、凸部の角が湾曲していることに代えて又は加えて、凹部の角が湾曲していてもよい。
　また、例えば、実施の形態では、端子接続構造及び表示装置をテレビジョン受像機に適用した場合を例として説明したが、当該端子接続構造及び表示装置は、その他の装置、例えばデジタルサイネージ又はスマートフォン等に適用してもよい。
　また、例えば、実施の形態では、端子接続構造を有する表示装置は、液晶パネル１１であったが、これに限られず、その他の表示装置、例えば有機ＥＬ（Electro Luminescence）ディスプレイであってもよい。
