Abstract

L'objet de l'invention est de divulguer une configuration d'une lentille à cristaux liquides à vitesse de réaction améliorée. Une lentille à cristaux liquides (11) possède un substrat (111), une électrode principale (114) et une électrode auxiliaire (115) formée sur le substrat (111), un substrat opposé (113) qui se trouve à l'opposé du substrat (111), une électrode commune (116) formée sur le substrat opposé (113), une couche de cristaux liquides (112) prise en sandwich entre le substrat (111) et le substrat opposé (113), et une unité de commande (119) pour commander les potentiels de l'électrode principale (114), l'électrode auxiliaire (115) et l'électrode commune (116). L'unité de commande (119) commute entre un état de MARCHE dans lequel une différence de potentiel existe entre l'électrode principale (114) et l'électrode commune (115) et un état d'ARRET dans lequel la différence de potentiel est inférieure à celle à l'état de MARCHE, et génère une différence de potentiel entre l'électrode principale (114) et l'électrode auxiliaire (115) lors de la commutation de l'état de MARCHE vers l'état d'ARRET.
