Abstract

　ソース配線Ｓｊと電圧選択回路１４の間に第１スイッチ素子Ｑ６を設け、ソース配線Ｓｊを分割した部分配線Ｓｊ（２）～Ｓｊ（０）間に第２スイッチ素子Ｑ２、Ｑ４を設ける。電圧印加期間では、第１スイッチがオン状態、第２スイッチがオン状態またはオフ状態となり、映像データＤｉｎの各ビットに応じた電圧が各部分配線に与えられる。電圧平均化期間では、第１スイッチがオフ状態、第２スイッチがオン状態となり、ソース配線Ｓｊの電圧は部分配線の電圧を平均化した電圧となる。平均化された電圧は、オン状態のアクティブ素子Ｑ１を含む画素回路Ａｉｊの画素電極Ｐｉｊに与えられる。これにより、オペアンプ回路を用いずにソース配線を駆動する低消費電力で高歩留まりの表示装置を提供する。
