In a particular embodiment, the fractional coverage louver device includes a transparent layer of material having a first surface and a second surface parallel thereto. A plurality of louver members disposed within the transparent layer of material provide fractional reflective coverage across the width of the transparent material. The louver members are aligned to receive light entering the first surface at a shallow angle relative to the first surface and direct the light out the second surface at a high angle relative to the second surface, thereby increasing the angular viewing range. Transparent areas between louver members allow a portion of incident ambient light to pass through the louver device without being reflected back to a viewer. As such, the louver device has advantageous contrast properties.
