Title (EN) LIQUID CRYSTAL DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE A CRISTAUX LIQUIDES
Abstract:
(EN) In order to extend the viewing angle of a liquid crystal display device a colour filter (23) having large retardation ($m(G) 100 nm) or supporting members (272) of polarizers (271) having large retardation ($m(G) 60 nm each) are used.
(FR) En vue d'élargir l'angle de visionnement d'un dispositif d'affichage à cristaux liquides, on utilise un filtre couleur (23) présentant un grand retard ($m(G) 100 nm) ou des éléments de support (272) de polariseurs (271) possédant un grand retard ($m(G) 60 nm chacun).
