Abstract

Dispositif d'affichage à couche de cristal liquide placée entre deux plaquettes et entre une électrode antérieure et une électrode arrière et à réflecteur intégré dans la cellule à cristal liquide. L'électrode antérieure 2 au moins est formée de segments et les parties du réflecteur 9 et/ou de l'électrode arrière 3 situées en face des conducteurs 31 d'arrivée aux segments sont à un potentiel électrique dont la différence par rapport au potentiel du conducteur correspondant 31 est inférieure à la tension de seuil de la couche de cristal utilisée. Application par exemple aux montres-bracelets.
