Abstract
【解決手段】各画素に設けられるトランジスタ6,7のゲート電極2−1、4−1を形成するゲートメタル層と同じ層にデータライン1−1を形成する。ゲートライン2−2及び電源ライン3をデータライン1−1に交差して異なる層に形成し、電源ライン3を水平方向のサブピクセルで共有する。
【選択図】図1A
Description
図1Aには、実施形態1の画素レイアウト、図1Bには画素等価回路、図2Aには図1Aのレイアウトの断面図が示されている。なお、図1Aは図2Aを上方から見た図である。
実施形態1では従来のLCDで用いられている低温ポリシリコンTFT製造プロセスと互換性のある製造プロセスで製造可能なように配慮して画素を形成した例を示した。しかし、将来、有機ELディスプレイが普及し、低温ポリシリコンTFTの製造プロセスが有機ELディスプレイ向けに改善された場合、図8に示される画素レイアウトも開口率向上に効果的である。ただし、等価回路は図1Bと同じであるため、図8には示していない。
