Abstract

Procédé de fabrication d'un filtre coloré La présente description concerne un procédé de fabrication d'un filtre coloré, comprenant les étapes successives suivantes : a) réaliser des ouvertures (111) dans une première couche (103) revêtant une première face (101T) d'un substrat (101), la première couche étant adaptée à transmettre de la lumière dans une première gamme de longueurs d'ondes ; b) revêtir la première couche (103) d'une deuxième couche (113) adaptée à transmettre de la lumière dans une deuxième gamme de longueurs d'ondes, différente de la première gamme de longueurs d'ondes ; c) insoler la deuxième couche (113) depuis une deuxième face (101B) du substrat (101) opposée à la première face (101T), en utilisant la première couche (103) comme masque ; et d) éliminer des parties de la deuxième couche (113) masquées par la première couche (103) lors de l'étape c). Figure pour l'abrégé : Fig. 1D
