A method for making a non-planar (three-dimensional) electrophoretic display including a light-transmissive front substrate that functions as a viewing surface. A light-transmissive conductive layer is incorporated into, or adhered to, the light-transmissive front substrate, whereupon a layer of electrophoretic encapsulated media is attached thereto. After the electrophoretic medium is deposited, a back electrode is attached or deposited. When a voltage is provided between the light-transmissive conductive layer and the back electrode, the image state of the electrophoretic medium is switched, thereby creating a color-changing surface. Such a color-changing surface can be incorporated into a toy, an appliance, an electronic device, or other suitable structure.
