Abstract: An optical article, such as a backlight for electronic display devices, is disclosed. The optical article includes a lightguide, a viscoelastic layer disposed on the light guide and a nanovoided polymeric layer disposed on the viscoelastic layer. The nanovoided polymeric layer comprises a plurality of interconnected nanovoids and at least some of the interconnected nanovoids are connected to one another by hollow passages. The lightguide may be optically coupled to a light source, and the viscoelastic layer and the nanovoided polymeric layer may be used in conjunction with the lightguide to manage light emitted by the light source. The viscoelastic layer may be a pressure sensitive adhesive.
