Abstract
【解決手段】EL素子に流す電流を大きくしたい画素ほど、該画素のEL素子に電圧または電流を供給する引き回し配線の幅を大きくした。これによって、EL素子に流す電流を大きくしたい画素ほど、該画素のEL素子に電圧または電流を供給する引き回し配線の配線抵抗が小さくなる。配線抵抗が小さくなると、引き回し配線における電位降下が小さくなり、EL素子に流す電流を大きくすることが可能になる。なお実際のパネルでは、引き回し配線を配置するスペースは限られているので、各色における引き回し配線の幅の比を変えることで、各色のEL素子に流れる電流の大きさのバランスを取ることが可能である。

Description
これは、有機EL材料によって、同じ印加電圧における電流密度の大きさが異なるためである。
Vr=a×Ir/WrVg=a×Ig/WgVb=a×Ib/Wb
Ir/Wr=Ig/Wg=Ib/Wb
Wr:Wg:Wb=Ir:Ig:Ib
(式4)
Wr:Wg:Wb≒7.5:3:5
例えば、3つ乃至6つまたはそれ以上のTFTを設けても構わない。本実施例では、EL表示装置が画素内に3つのTFTを設けている構成について示す。
TaN膜はスパッタ法で形成し、Taのターゲットを用い、窒素を含む雰囲気内でスパッタした。また、W膜は、Wのターゲットを用いたスパッタ法で形成した。その他に6フッ化タングステン(WF6)を用いる熱CVD法で形成することもできる。いずれにしてもゲート電極として使用するためには低抵抗化を図る必要があり、W膜の抵抗率は20μΩcm以下にすることが望ましい。W膜は結晶粒を大きくすることで低抵抗率化を図ることができるが、W膜中に酸素などの不純物元素が多い場合には結晶化が阻害され高抵抗化する。従って、本実施例では、高純度のW(純度99.9999%または99.99%)のターゲットを用いたスパッタ法で、さらに成膜時に気相中からの不純物の混入がないように十分配慮してW膜を形成することにより、抵抗率9〜20μΩcmを実現することができた。
とし、1Paの圧力でコイル型の電極に500WのRF(13.56MHz)電力を投入してプラズマを生成してエッチングを行った。ここでは、松下電器産業(株)製のICPを用いたドライエッチング装置(Model E645−□ICP)を用いた。基板側(試料ステージ)にも150WのRF(13.56MHz)電力を投入し、実質的に負の自己バイアス電圧を印加する。この第1のエッチング条件によりW膜をエッチングして第1の導電層の端部をテーパー形状とする。第1のエッチング条件でのWに対するエッチング速度は200.39nm/min、TaNに対するエッチング速度は80.32nm/minであり、TaNに対するWの選択比は約2.5である。また、この第1のエッチング条件によって、Wのテーパー角は、約26°となる。
フィルム、マイラーフィルム、ポリエステルフィルムまたはアクリル樹脂フィルムを用いることができる。また、アルミニウムホイルをPVFフィルムやマイラーフィルムで挟んだ構造のシートを用いることもできる。
あるいはエキシマレーザー(波長308nm)を用い、線状ビームを形成し、石英基板を通過させれば良い。なお、エキシマレーザーはガラス基板を通過しない。したがって、素子形成基板3101としてガラス基板を用いるのであれば、YAGレーザーの基本波、第2高調波、第3高調波を用い、好ましくは第2高調波(波長532nm)を用いて線状ビームを形成し、ガラス基板を通過させれば良い。
基板3201上にスイッチング用TFT3205と、EL駆動用TFT3204とが形成されている。3203はEL素子であり、EL駆動用TFT3204によってEL素子3203に流れる電流が制御される。
また、その他にも様々な電子機器の表示部として本発明のEL表示装置を用いることができる。
であり、本体2301、記録媒体(DVD等)2302、操作スイッチ2303、表示部(a)2304、表示部(b)2305等を含む。表示部(a)2304は主として画像情報を表示し、表示部(b)2305は主として文字情報を表示するが、本発明のEL表示装置はこれら表示部(a)、(b)2304、2305に用いることができる。なお、記録媒体を備えた画像再生装置には家庭用ゲーム機器なども含まれる。
