Abstract

L'invention a pour objet de réduire l'apparition de moirage, dans un dispositif d'affichage dans lequel une pluralité de panneaux d'affichage est superposée. Le dispositif d'affichage de l'invention est équipé : d'un premier panneau d'affichage dans lequel des pixels sont formés dans une région divisée par un premier motif de bande; et d'un second panneau d'affichage dans lequel des pixels sont formés dans une région divisée par un second motif de bande. Le premier et le second panneau d'affichage sont disposés en superposition. Une rangée de filtres colorés correspondant aux pixels formés sur le premier et/ou le second panneau d'affichage, est inclinée selon un angle prédéfini par rapport à une rangée de filtres colorés correspondant aux pixels formés sur l'autre panneau d'affichage.
