Abstract

La présente invention porte sur un panneau d'affichage à cristaux liquides qui peut réduire l'apparition d'une fuite de lumière au niveau d'une position chevauchant une saillie de commande d'alignement de cristaux liquides (34). Ce panneau d'affichage à cristaux liquides est pourvu : d'une électrode de pixel (15) ; d'un élément de commutation ; d'une première ligne de câblage d'arrêt de la lumière (14) ; d'une seconde ligne de câblage d'arrêt de la lumière (13) ; de la saillie de commande d'alignement de cristaux liquides (34). La première ligne de câblage (14) et la seconde ligne de câblage (13) sont disposées dans différentes couches, un premier film isolant (22) étant interposé entre celles-ci. La seconde ligne de câblage (13) et l'électrode de pixel (15) sont disposées dans différentes couches, un second film isolant (23) étant interposé entre celles-ci. La première ligne de câblage (14), la seconde ligne de câblage (13) et la saillie de commande d'alignement de cristaux liquides (34) ont respectivement des parties de chevauchement qui se chevauchent les unes les autres. La largeur de la partie de chevauchement de la première ligne de câblage (14) ou de la seconde ligne de câblage (13), dont l'épaisseur est supérieure à l'autre, est inférieure à la largeur de la partie de chevauchement de l'autre ligne de câblage dont l'épaisseur est inférieure ; la largeur de la partie de chevauchement de la saillie de commande d'alignement de cristaux liquides (34) est inférieure à la largeur de la partie de chevauchement de la ligne de câblage dont l'épaisseur est inférieure.
