Abstract
(EN)
A liquid crystal display comprises a backlight (3), a liquid crystal panel (1) for display, and a visual field angle control panel (2) for controlling the angle of the visual field of the liquid crystal panel (1). A lens sheet (41) is provided between the backlight (3) and the liquid crystal panel (1). Consequently, a display system having an increased shield effect can be provided.

La présente invention concerne un affichage à cristaux liquides comprenant un rétro-éclairage (3), un panneau à cristaux liquides (1) destiné à l'affichage, et un panneau de régulation d'angle de champ visuel (2) destiné à réguler l'angle du champ visuel du panneau à cristaux liquides (1). Une feuille lenticulaire (41) est disposée entre le rétro-éclairage (3) et le panneau à cristaux liquides (1). En conséquence, on obtient un système d'affichage qui a un effet de blindage accru.
