Abstract
(EN) A liquid crystal panel and a manufacturing method therefor, and a 3D display device, which are used for separating a left-eye image from a right-eye image directly using a liquid crystal box (25), thereby simplifying the manufacturing process of the liquid crystal box (25) in a naked-eye 3D mode. The liquid crystal panel comprises an upper substrate (20), a lower substrate (21) and a liquid crystal box (25) which is formed by liquid crystal molecules (24) and is located between the upper substrate and the lower substrate (20, 21). The liquid crystal box (25) comprises a display layer and a grating layer. The grating layer is arranged close to the upper substrate (20). The grating layer comprises shading areas and light-transmitting areas, wherein each of the shading areas comprises shading liquid crystal molecules (242), each of the transmitting areas comprises light-transmitting liquid crystal molecules (241), and the shading areas and the light-transmitting areas are arranged at intervals.
(FR) L'invention concerne un panneau à cristaux liquides et son procédé de fabrication, et un dispositif d'affichage en 3D, lesquels servent à séparer une image d'œil gauche d'une image d'œil droit directement au moyen d'un boîtier de cristaux liquides (25), simplifiant ainsi le processus de fabrication du boîtier de cristaux liquides (25) dans un mode de 3D à l'œil nu. Le panneau à cristaux liquides comprend un substrat supérieur (20), un substrat inférieur (21) et un boîtier à cristaux liquides (25) qui est formé par des molécules de cristaux liquides (24) et est situé entre le substrat supérieur et le substrat inférieur (20, 21). Le boîtier de cristaux liquides (25) comprend une couche d'affichage et une couche de réseau. La couche de réseau est agencée à proximité du substrat supérieur (20). La couche de réseau comprend des zones d'ombrage et des zones transparentes, chacune des zones d'ombrage comprenant des molécules de cristaux liquides d'ombrage (242), chacune des zones transparentes comprenant des molécules de cristaux liquides transparentes (241), et les zones d'ombrage et les zones transparentes étant agencées par intervalles.
