摘要：
A lightguide (3690) is disclosed. The lightguide includes a light guiding layer (3610) for propagating light by total internal reflection, and an optical film (3640) 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 (3614, 3642) in the lightguide are in physical contact with each other. The lightguide can be used as blacklight in a display system.
