Description
主画素電極PAは、コンタクト部PCから画素PXの上側端部付近まで第2方向Yに沿って直線的に延出している。主画素電極PAは、第1方向Xに沿って略同一の幅を有する帯状に形成されている。
図5は、中間調の画面の中央に白色の窓WWを表示した一例を示す図である。
ソース配線Sk、Sk+1(kは正の整数)が白色の窓WWを含む列に配置される場合、N番目のフレーム期間において、最初の期間t1においてソース配線Skには共通電極電位Vcom(例えば0V)に対して正極性の中間調表示に対応する電圧(例えば2V)が印加され、ソース配線Sk+1には共通電極電位Vcomに対して負極性の中間調表示に対応する電圧(例えば−2V)が印加される。この期間t1において、白色の窓WWの上部(画素P1)に中間調の信号が書き込まれる。
