Abstract

Dispositif d'affichage à cristaux liquides ayant une couche de cristaux liquides (30) contenant des molécules de cristaux liquides alignées verticalement, agencée entre un substrat de filtre coloré (10) ayant une matrice noire (14) et une couche de filtre colorée (15) et un substrat d'électrode pixel (20) ayant une partie formant électrode pixel (22). Dans ce dispositif d'affichage à cristaux liquides, au moins une partie linéaire partielle de la matrice noire (14) prévue pour s'étendre de manière linéaire sur le substrat de filtre coloré (10) est formée pour présenter une structure de saillie (16) faisant saillie vers le côté substrat d'électrode pixel (20) et s'étendant de manière linéaire le long de l'au moins une partie linéaire partielle.
