A light guide screen louver device. In a particular embodiment, the device includes a translucent layer of material having an inner surface and, parallel thereto, an outer surface. A plurality of reflective louver members are disposed within the layer of material. The louver members are aligned to receive light entering the inner surface from the light guide screen at a low angle relative to the inner surface and direct the light out the outer surface at a high angle relative to the outer surface. In at least one embodiment, the louver members are holographic.
