Abstract
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.
Claims25
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, and wherein the optical film has a reverse birefringence dispersion of D<1.
An LCD polarizer film composite comprising a polarizer and 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, and wherein the optical film has a reverse birefringence dispersion.
A method of making an optical film comprising mixing a first component having a birefringence dispersion of D1>1 and a second component having a birefringence dispersion of D2<1 and forming a film from the resulting mixture, wherein the birefringence ratio of the first and second component is delta n1/delta n2>0, and wherein the optical film has a reverse birefringence dispersion.
