実施の形態2の液晶表示装置の構成は図2のとおりである。実施の形態2の液晶表示装置では、図8〜図11に示すように、まず時刻Tbで、走査信号線G1の電位をゲートオフ電位VGLから立ち上げ、データ信号線SLにオフセット電位Vouを出力するとともに共通電極COMに表示センター電位Vcomを出力すると、時刻Tdで、データ信号線SLがオフセット電位Vouに充電され、共通電極COMが表示センター電位Vcomに充電される。
実施の形態3の液晶表示装置の構成は図2のとおりである。実施の形態2の液晶表示装置では、図12〜15に示すように、まず、時刻Tbで走査信号線G1の電位の立ち上げを開始するとともに、データ信号線SLにグラウンド電位Vgdを出力するとともに共通電極COMにマイナス電位Vngを出力する。時刻Td(第1タイミング)で、走査信号線G1の電位はトランジスタの閾値電位Vthよりも高いゲートオン電位VGH(第1電位)に達する。
上記各実施の形態では、図20に示すように、電源回路PWCから各ドライバD(GD・SD・CMD)への電源供給は時刻Taで停止され、各ドライバD(GD・SD・CMD)の残留電圧によって時刻Ta〜時刻Tiまでのシーケンスが行われる。もっとも、時刻Tiまで電源回路PWCから各ドライバへの電源供給を行っても構わない。
