Description
<第1実施形態>
先ず、本実施形態に係る液晶装置の全体構成について、図1及び図2を参照して説明する。ここに図1は、本実施形態に係る液晶装置の全体構成を示す平面図であり、図2は、図1のH−H’線断面図である。
各々には、画素電極9及び本発明に係る「トランジスタ」の一例としての画素スイッチング用のTFT30が形成されている。TFT30は、画素電極9に電気的に接続されており、本実施形態に係る液晶装置の動作時に画素電極9をスイッチング制御する。画像信号が供給されるデータ線6は、TFT30のソース領域に電気的に接続されている。データ線6に書き込む画像信号S1、S2、…、Snは、この順に線順次に供給しても構わないし、互いに隣り合う複数のデータ線6同士に対して、グループ毎に供給するようにしてもよい。
<第2実施形態>
次に、第2実施形態について図7から図10を参照して説明する。第2実施形態では、第2シールド層5と第2ドレイン中継配線2を容量電極として用い、蓄積容量70(図3参照)を形成している点において第1実施形態と異なる。
次に、図11を参照して、上述した実施形態に係る電気光学装置500をライトバルブとして用いたプロジェクタについて説明する。
