Abstract

La présente invention concerne une pellicule de réglage de la lumière (10) comprenant un réseau de polymère polymérisé variant spatialement dans une direction normale par rapport à la surface de la pellicule, le réseau de polymère polymérisé étant constitué par un matériau polymère réticulé de poids moléculaire élevé mélangé à un matériau nématique de faible poids moléculaire présentant un ordre de cristal liquide cholestérique, un champ électrique imprimé sur la pellicule permettant de régler la largeur de bande de réflexion d'une lumière à polarisation circulaire.
