-11- ABSTRACT OF DISCLOSURE DISPLAY PANEL AND METHOD OF MAKING IT A method of making a display panel made up of a base plate carrying an array of anodes and an array of cathodes disposed transverse to each other, insulating strips on the face plate to space the cathodes from a first apertured plate electrode, a second apertured electrode whose apertures are display cells seated on the first plate electrode, and the face plate assembly carrying an A.C. electrode. According to the method, the insulating strips, the first apertured plate electrode, and the second apertured plate are made by coating the apertured plate electrode on both surfaces with insulating material and photoetchable material, exposing and developing strip patterns in one layer and aperture patterns in the other, and then etching to remove undesired material to leave the desired strips on one surface of the plate electrode and the apertured plate on the other.
