    摘要: An asymmetric transmission film including a body having a first surface and a second surface opposite to the first surface and a transmittance control member disposed in the body such that a forward transmittance of light passing in a direction from the first surface toward the second surface and a reverse transmittance of light passing in a direction from the second surface toward the first surface are different from each other.

    摘要: 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.
