Abstract:
A reflective image display comprising of a reflection enhancing layer comprising of a plurality of approximately spherical indentations is placed adjacent a sheet comprising of a plurality of hemispherical protrusions. The radii of curvature of the spherical indentations substantially coincides with the center of curvature of the adjacently located hemispheres to enhance the white paper-like appearance of the display while efficiently enabling optional color filters to yield saturated color.
