Abrégé
(EN)
The invention includes a method for reducing moire effect of an LCD device. An LCD device is provided comprising a liquid crystal panel having a front side and a back side. A light control film is placed on one side of the liquid crystal panel. The light control film comprises louver elements. A polarizer is placed on at least one side of the liquid crystal panel. At least one of the optical components placed on a front side of the liquid crystal panel is subjected to a haze treatment.

La présente invention concerne un procédé permettant de réduire le moiré d'un dispositif LCD. Un dispositif LCD comprend un panneau d'affichage à cristaux liquides ayant un côté avant et un côté arrière. Un film anti-reflet est placé sur un côté du panneau. Le film anti-reflet comprend des éléments d'évent. Un polariseur est placé sur au moins un côté du panneau. Au moins un des éléments optiques placés sur un côté avant du panneau d'affichage à cristaux liquides est soumis à un traitement de trouble.
