【解決方法】 本発明は、主に絶縁表面を有する基板上において、液滴吐出法によって配線材料等を直接パターニングを行うに際し、下層部とのコンタクトを形成する開口部が設けられた絶縁膜上に、液滴吐出法により導電性組成物よりなる液滴を滴下することで少なくとも前記開口部を含む位置に配線を作製し、前記配線が作製された基板に加熱処理を行うことで、前記開口部上の前記配線の表面位置とそれ以外の部分の前記配線の表面位置における高さを概略一致させ、かつ前記開口部を充填することを特徴とする。

Description
図1(A)に本発明の実施の一形態を示す。基板101上に形成された下地絶縁膜102上の導電層103に層間絶縁膜104を介して導通をとる例を示す。
本発明の他の実施の形態について図2を用いて説明する。
本実施の形態では他の実施の形態について図3を用いて説明する。TFTに接続するように開けられたコンタクトホールに液滴吐出法を用いてノズル301から導電性組成物が分散された液滴を滴下し、配線302を形成する。
本発明の他の実施の形態について図4を参照して説明する。図4(A)は図4(B)をA−A‘で切断した場合の斜視図である。なお、この図面の膜圧などの比率はわかりやすさのために変更してあるため、実際の比率と異なる場合がある。また、記載を省略している部分もある。
この後、共通電極617、カラーフィルタ618、ブラックマトリックス619などが形成された対向基板620と貼り合わせる。そして所定の方法で液晶621を注入し、液晶表示装置を完成する。(図6(D))。
図15(B)はデジタルスチルカメラであり、本体2101、表示部2102、受像部2103、操作キー2104、外部接続ポート2105、シャッター2106等を含む。本発明は、表示部2102に適用することができる。
