摘要： Lightguide is disclosed. The lightguide includes a light guiding layer for propagating light by total internal reflection, and an optical film that is disposed on the light guiding layer. The optical film includes a plurality of voids, an optical haze that is not less than about 30%, and a porosity that is not less than about 20%. Substantial portions of each two neighboring major surfaces in the lightguide are in physical contact with each other.
