Title (EN) COMPLEX LIGHT-COMPENSATION C PLATE WITH TWO OR MORE OF C PLATES DIFFERENT IN DISPERSION RATIO VALUE AND LIQUID CRYSTAL DISPLAY USING THE SAME
(FR) PLAQUE C POUR COMPENSATION DE LUMIERE COMPLEXE A PLUSIEURS PLAQUES C DIFFERANT PAR LEURS COEFFICIENTS DE DISPERSION, ET AFFICHEUR A CRISTAUX LIQUIDES L'UTILISANT
Abstract: front page image
(EN)Disclosed is a complex light compensation C plate including at least two C plates representing different dispersion ratio values, respectively. The complex light compensation C plate improves a contrast characteristic of a liquid crystal display device at various viewing angles and has a broadband wavelength dispersion characteristic capable of minimizing color variation depending on various viewing angles in a black state of an LCD.
(FR)La présente invention concerne une plaque C de compensation de lumière complexe comportant deux plaques représentant chacune une valeur différente du coefficient de dispersion. Cette plaque C de compensation de lumière complexe améliore une caractéristique du contraste d'un dispositif à afficheur à cristaux liquides sous différents angles d'observation. En outre, cette plaque présente une caractéristique de dispersion de longueur d'ondes large bande capable de minimiser les écarts de couleurs selon divers angles d'observation dans un état noir d'un écran à cristaux liquides.
