Abstract

　走査信号線（１６）およびデータ信号線（１５）からなる信号線、該信号線に接続されたトランジスタ（１２）、並びに上記信号線で画される画素領域に対応して設けられた画素電極（１７）を有するアクティブマトリクス基板と対向基板との間に、スプレイ配向からベンド配向へ転移する液晶層を備えたＯＣＢモード液晶パネル（１０ａ）であって、上記アクティブマトリクス基板の表面には、ベンド配向からスプレイ配向への逆転移を抑制するための段差部（７）が、隣り合う２つの画素電極（１７）の間隙と上記信号線（１５・１６）とに重なるように形成されている。上記構成によれば、ＯＣＢモード液晶パネルにおいて、表示中の逆転移（ベンド→スプレイ転移）によるスプレイ配向が画素内に広がることを抑えられる。
