Abstract

One example of a display device includes a first layer and a second layer including a conductive material. The second layer is attached to the first layer such that a surface of the second layer facing the first layer is exposed along an edge of the second layer. The second layer supports an electronic paper display imageable by receiving charges on an imaging surface of the electronic paper display. The second layer is electrically coupled to a counter-electrode of the electronic paper display.
