Abstract
【解決手段】 走査信号線の延在方向には、隣接する2本の走査信号線のうちの一方にTFTが接続された画素と、他方にTFTが接続された画素とが交互に配置されており、1本の映像信号線を挟んで隣接する2つの画素は、各画素のTFTが該映像信号線に接続され、かつ、各画素のTFTと走査信号線との接続位置の関係が、映像信号線の延在方向に並んだ2つの画素の組毎に反転する液晶表示装置において、走査信号を入力する走査信号線が変わる毎に、共通電圧を第1の電位と前記第1の電位よりも電位が高い第2の電位とに交互に切り替え、共通電極に前記第1の電位の共通電圧が入力されるときには前記第1の電位よりも高い電位の映像信号を入力し、前記共通電極に前記第2の電位の共通電圧が入力されるときには前記第2の電位よりも低い電位の映像信号を入力する。
