OPTICAL FILMS HAVING REVERSE DISPERSION

摘要

This invention relates to an optical film comprising a first component having a birefringence dispersion of D1> 1 and a second component having a birefringence dispersion of D2< 1, wherein the birefringence ratio of the first and second component is delta n1 /delta n2 > 0, wherein the optical film has a reverse birefringence dispersion of D<1.
