Description
本発明の実施例1について、図5、6を用いて説明する。図6の(e)に示す薄膜トランジスタアレイ20を、図5の(a)〜(c)、図6の(d)〜(e)に示した工程によって作製した。ただし、画素数は1200×100である。まず初めに、絶縁基板1であるPEN上に、蒸着によってAlを50nm成膜し、フォトリソおよびウェットエッチによってゲート電極2、ゲート配線G、キャパシタ電極10、キャパシタ配線Cを形成した(図5の(a))。この時、ゲート配線Gおよびキャパシタ配線Cは、4列ごとに1行ずれる形状とした。次に、ポリビニルフェノール溶液をスピンコートし、150℃焼成することにより、ゲート絶縁膜3としてポリビニルフェノールを1μm形成した。さらに、ソース電極4、ソース配線S、ドレイン電極5、画素電極7として、Agインクをオフセット印刷し180℃で焼成することによってパターンを形成した(図5の(b))。
本発明の実施例2について、図5、6を用いて説明する。図6の(f)に示す薄膜トランジスタアレイを、図5(a)〜(c)、図6(d)〜(f)の工程によって作製した。ただし、画素数は1600×75である。まず初めに、絶縁基板1であるPEN上に、ゲート電極2、ゲート配線G、キャパシタ電極10、キャパシタ配線Cとして、Agインクをオフセット印刷し180℃で焼成することによってパターンを形成した(図5の(a))。この時、ゲート配線Gおよびキャパシタ配線Cは、(5列で1行、5列で1行、6列で1行)のずれを繰り返す形状とした。次に、ポリビニルフェノール溶液をスピンコートし、150℃焼成することにより、ゲート絶縁膜3としてポリビニルフェノールを1μm形成した。さらに、ソース電極4、ソース配線S、ドレイン電極5、画素電極7として、Agインクをオフセット印刷し180℃で焼成することによってパターンを形成した(図5の(b))。
