    Abstract: A light management unit is described for attachment to a display module, especially suited for an LCD TV or LCD monitor. The light management unit includes a directionally recycling layer including a structured side and a planar side where the structured side includes prism structures. The light management unit also includes a reflective polarizer positioned on the planar side of the directionally recycling layer. The light management unit also includes a diffusion structure incorporated into either the directionally recycling layer or between the directional recycling layer and the reflective polarizer. The diffusion structure causes a level of diffusion that is sufficient to prevent the appearance of colored bands when a viewer positioned along a line of sight that is perpendicular to the direction of the prism structures views the light management unit, illuminated from below, at an oblique angle from a vertical axis.
