More Information
Summary:An optical film including a refractive index changing unit region comprising at least one high-refraction unit region and at least one low-refraction unit region, the refractive index changing unit region in which a refractive index varies along the plane direction, is provided. The optical film has excellent abrasion resistance and pressure resistance while having excellent light extraction efficiency.
