A display system for a refrigerated display case includes a door assembly which permits access to a product storage compartment. The door assembly includes an electronic display layer positioned within an enclosure defined by a front cover layer, a rear cover layer, and a spacer extending about a perimeter of interior surfaces of the front and rear cover layers. The front cover layer permits viewing of images displayed at the electronic display layer through the front cover layer. Electronic equipment for operating the electronic display layer is located outside of the enclosure.
