Abstract: A diffuser including opposing structured first and second major surfaces is described. The first major surface includes a first plurality of surface structures providing a uniform first haze. The second major surface includes a first portion adjacent an edge and a second portion adjacent the first portion. The first portion includes a first region and a second region between the first region and the second portion. The second major surface includes a second plurality of surface structures providing a uniform second haze over the second portion and providing a third haze in the first portion. The third haze in the first region is higher than the second haze, and the third haze in the second region is monotonically decreasing. The second portion has a surface area of at least 90 percent of a surface area of the second major surface.
