[0033] The driving layer 114A may include active devices, signal transmission lines, capacitors, and/or the like that together construct the required circuit structure for providing the electric field driving the display medium layer DM (shown in FIG. 1). The driving layer 114A may include a plurality of patterned and/or non-patterned conductive film layers and a plurality of patterned and/or non-patterned insulating film layers to define the active devices, the signal transmission lines, the capacitors or the like.
