Abstract

Un panneau obturateur à barrière de parallaxe (20) comprend un premier substrat transparent (21) et un second substrat transparent (22) positionnés l'un en face de l'autre. Le premier substrat transparent (21) comprend, sur sa surface sur le côté faisant face au second substrat transparent (22), un câblage métallique de couche inférieure (71), un film d'isolation intercouche (61) formé sur le câblage métallique de couche inférieure (71) et un câblage de connexion (74) formé sur le film d'isolation intercouche (61). Le câblage métallique de couche inférieure (71) et le câblage de connexion (74) sont connectés par l'intermédiaire d'un trou de contact (73) formé dans le film d'isolation intercouche (61). Le second substrat transparent (22) comprend, sur sa surface sur le côté faisant face au premier substrat transparent (21), un espaceur de colonne (27) positionné de manière à être superposé sur le trou de contact (73) dans une vue en plan.
