  • two subpixels corresponding to the same polarization axis are displayed in succession, and image data having the same polarization axis is displayed, and between these image liquid crystal elements. Since the provided light-shielding liquid crystal element does not transmit light, the plane of the light-shielding portion can be obtained even if the viewing angle is widened compared to the conventional configuration in which a light-shielding portion is provided for each pixel. The visual area is reduced, the luminance value of the displayed image can be increased, and the image quality of the displayed image can be improved.
  • the sub-pixel C of the liquid crystal panel 101 facing the light shielding portion 103d of the filter plate 103 does not emit light (off) as the light shielding liquid crystal element 101d. Since it is used as a state, the amount of light that goes around the light-shielding portion is reduced, so that interference can be further reduced and occurrence of crosstalk can be suppressed.

Abstract

La présente invention concerne un écran d'affichage d'images stéréoscopiques comportant : une dalle à cristaux liquides, caractérisé en ce qu'un pixel comporte trois sous-pixels constitués d'un premier sous-pixel (L), d'un deuxième sous-pixel (C) et d'un troisième sous-pixel (R), le deuxième sous-pixel étant utilisé comme élément (101d) à cristaux liquides arrêtant la lumière qui ne transmet pas la lumière dans la direction d'alignement des premier, deuxième et troisième sous-pixels, et les premier et troisième sous-pixels, qui jouxtent chaque côté du deuxième sous-pixel, étant positionnés de façon alternée en tant qu'éléments à cristaux liquides pour une image (101a) d'œil gauche et éléments à cristaux liquides pour une image (101b) d'œil droit ; et une plaque filtrante caractérisée en ce que des premières sections filtrantes (103a), qui servent de premier axe de polarisation pour la lumière transmise, sont disposées dans des positions qui chevauchent les éléments à cristaux liquides de l'image d'œil gauche dans une vue en plan, en ce que des deuxièmes sections filtrantes (103b), qui servent de deuxième axe de polarisation pour la lumière transmise, sont disposées dans des positions qui chevauchent les éléments à cristaux liquides de l'image d'œil droit dans une vue en plan, et en ce que des sections (103) arrêtant la lumière qui arrêtent la lumière sont disposées dans des positions qui chevauchent les deuxièmes sous-pixels dans une vue en plan.
