Abstract
A display device utilizes an acrylic sheet frosted throughout its structure and an opaque surface or panel. The acrylic sheet or panel is placed substantially parallel to the opaque surface or panel such that the acrylic sheet or panel and the opaque surface or panel are separated by a distance of between 1 and 185 millimeters (0.04 to 7.3 inches). Display items are mounted on item supports on the display side of the acrylic sheet or panel. Shadows cast by the display items or item supports on the acrylic sheet are absorbed by the acrylic sheet or panel due to the nature of the frosted acrylic material and spacing between the acrylic sheet or panel and the opaque background surface or panel
