Abstract

La présente invention concerne un panneau à cristaux liquides (100) qui comprend une partie d'affichage plate (110) et une partie de courbure (120) formée par courbure d'une extrémité latérale de la partie d'affichage plate (110), cette partie d'affichage plate (110) servant à l'affichage du panneau à cristaux liquides (100), et la partie de courbure (120) servant au câblage de circuit dudit panneau à cristaux liquides (100). La présente invention se rapporte également à un afficheur à cristaux liquides muni du panneau à cristaux liquides (100), l'afficheur à cristaux liquides comportant aussi un module de rétroéclairage (200). La partie d'affichage plate (110) se situe sur une surface supérieure du module de rétroéclairage (200), et la partie de courbure (120) se trouve en regard du côté latéral de ce module de rétroéclairage (200). Dans le panneau à cristaux liquides (100) et l'afficheur à cristaux liquides, une zone de cadre pour le câblage de circuit est disposée à l'emplacement de la partie de courbure (120) invisible dudit panneau à cristaux liquides (100), de manière à empêcher la zone de cadre d'occuper l'espace de la partie d'affichage plate (110) pour l'affichage, ce qui permet d'augmenter le rapport d'occupation d'écran du panneau à cristaux liquides (100).
