The illustrated display panel includes a matrix of communicating gas-filled display cells. A first layer includes an enlarged first plate having grooves in it, with first electrodes seated in the grooves, and second electrodes supported across them. A second layer includes an apertured plate seated on the second electrodes, with third electrodes positioned on the top surface of the second plate. The first electrodes residing in the grooves in one extension of the first plate are exposed and are accessed there by connector contacts. The third electrodes are fitted at one end into grooves in another extension of the first plate. The electrodes and plates forming the device may also be aligned with reference to the grooves in the base plate.
