US 2006/0141170 A1 · Optical film and method for manufacturing the same

Abstract

The present invention discloses an optical film comprising a substrate and a material layer. The material layer formed on the substrate further comprises a birefringent material and a dye material capable of absorbing light within a wavelength range. The present invention further provides a method for forming an optical film comprising steps of: preparing an absorbent solution by mixing a birefringent material and a dye material capable of absorbing light within a wavelength range into a solvent; forming a film by coating the absorbent solution on a top surface of a substrate; vaporizing the solvent contained in the film; and curing the optical film.
