1. A display having a substrate assembly, the substrate assembly comprising:

  • a transparent conducting common electrode;

    a plurality of opaque display elements; and

    a plurality of common bus lines made from a non-transparent conductor, the non-transparent conductor having a lower resistance than the transparent conducting common electrode, the common bus lines connected to the common electrode and positioned at a different layer in the substrate assembly than the opaque display elements such that, despite the existence of the common bus lines, an aperture of the display can be maintained at any reference aperture that would have been possible in the absence of the plurality of common bus lines such that the opaque display elements and the common bus lines substantially overlap one another at least in areas used for a display functionality of the display; and

    wherein the substrate assembly further includes a pixel electrode positioned in proximity to the common electrode, and a voltage between the pixel electrode and the common electrode determines a display functionality of a particular pixel; and

    wherein the plurality of opaque display elements includes at least a plurality of gate lines or data lines and wherein the at least the plurality of gate lines or data lines overlap substantially the entirety of the common bus lines.
