A liquid crystal display device includes a TFT for controlling voltage application in accordance with respective pixels and a capacitor connected to the TFT. After a corresponding voltage is applied to each pixel, one side of the potential of the capacitor is changed. One terminal of the N-th line capacitor is connected to the gate line of the (N-1)-th line TFT. After the gate of the N-th line TFT is turned off, the gate voltage of (N-1)-th line is changed. Il est prévu un dispositif d'affichage à cristaux liquides comprenant un TFT régulant l'application de tension selon les pixels respectifs et un condensateur connecté au TFT. Après application d'une tension correspondante à chaque pixel, un côté du potentiel du condensateur est changé. Une borne du condensateur de ligne N est connectée à la ligne de grille du TFT de la ligne N-1. Après extinction de la grille du TFT de ligne N, la tension de grille de ligne N-1 est changée.
