Abstract

La présente invention concerne un filtre coloré et son procédé de fabrication. Le procédé comprend les étapes consistant à : former une matrice noire (20) sur un substrat (10) ; au moyen d'un premier masque (100), former une première résistance de couleur (31) sur le substrat (10) et former une première partie d'espaceur (32) sur la matrice noire (20) ; au moyen d'un deuxième masque (200), former sur le substrat (10) une deuxième résistance de couleur (41) disposée avec un intervalle à partir de la première résistance de couleur (31) et former une seconde partie d'espaceur (42) sur la première partie d'espaceur (32) ; et, au moyen d'un troisième masque (300), former sur le substrat (10) une troisième résistance de couleur (51) disposée avec un intervalle à partir de la première résistance de couleur (31) et de la deuxième résistance de couleur (41). La matrice noire (20), la première partie d'espaceur (32) et la seconde partie d'espaceur (42) se chevauchent de manière à former un espaceur destiné au filtre coloré, ce qui permet de former l'espaceur sans autre processus de fabrication de masques, de réduire le coût de fabrication et d'empêcher l'espaceur de glisser vers le bas dans des zones de transmission de lumière faisant partie de pixels, ce qui provoque le phénomène de moiré lorsque les panneaux sont comprimés.
