The first image is rendered in reflected light and the second image is rendered in transmitted light. According to one example, a second filter layer may be provided on a second side of the substrate such that features of the filter layer and second features of the second filter layer may be at least partially out of vertical alignment in order to define a plurality of light ray entry angles.
