Abstract

L'invention fournit un procédé de fabrication de couche de cristaux liquides cholestériques qui inclut : une étape au cours de laquelle une composition qui contient un composé cristallin liquide, et un agent chiral dont le pouvoir d'induction de spirale varie en fonction de l'irradiation lumineuse, est appliquée sur un substrat ; une étape au cours de laquelle une force de cisaillement est conférée à la surface de ladite composition appliquée sur ledit substrat ; et une étape au cours de laquelle un rayonnement ultraviolet qui contient une longueur d'ondes faisant varier le pouvoir d'induction de spirale dudit agent chiral dont le pouvoir d'induction de spirale varie en fonction de l'irradiation lumineuse, irradie ladite composition à laquelle ladite force de cisaillement est conférée.
