ABSTRACT:
Reflective image-providing displays viewed with holographically diffused light are provided. As one particular and preferred embodiment, a liquid crystal display component is presented comprising a liquid crystal display element backed with a reflective transmission holographic diffuser. Images of good contrast may be displayed and viewed from the liquid crystal display component under ambient lighting conditions and without further requirement of supplemental light sources, such as edge-lighting and backlighting.
