Abstract: front page image
(EN) A multilayer compensator comprising one or more polymeric layers A and one or more polymeric layers B, wherein said layers A comprise a polymer having an out-of-plane birefringence not more negative than -0.01, said layers B comprise an amorphous polymer having an out-of-plane birefringence more negative than -0.01, and the overall in-plane retardation (Rin) of said multilayer compensator is greater than 20nm and the overall out-of-plane retardation (Rth) of said multilayer compensator is more negative than -20nm.
(FR) L'invention concerne un compensateur multicouche comprenant une ou plusieurs couches polymères A et une ou plusieurs couches polymères B, les couches A comprenant un polymère à biréfringence hors plan pas plus négative que -0,01, les couches B comprenant un polymère amorphe à biréfringence hors plan plus négative que -0,01, le retard global en plan (Rin) de ce compensateur multicouche étant supérieur à 20 nm et le retard hors plan (Rth) de ce compensateur étant plus négatif que -20 nm.
