Abstract: A pair of insulating substrates are positioned in spaced parallel relation having inside surfaces opposite each other with a gap filled with gas capable of ionization. A first group of electrodes are positioned on the inside surfaces of one of the substrates, and a second group of electrodes are positioned on the inside surfaces of the other of the substrates. The first group of electrodes are positioned in rows and the second group of electrodes are positioned in columns, and the first and second groups of electrodes are transversely positioned relative to each other. The surfaces of the first and second groups of electrodes are covered with dielectric layers, and each of the dielectric layers is covered with a protective layer to protect the surfaces inside the display device from sputtering. Each cross point of an electrode of the first group and an electrode of the second group is a discharge point for display.

Abstract: A pair of insulating substrates, at least one of which provides a group of electrodes on the inside surface, are positioned in spaced parallel relation having inside surfaces opposite each other with a gap filled with ionizable gas. The surface of the group of electrodes is covered with a dielectric layer, and this dielectric layer is covered with a material having a high secondary electron emissivity by introducing a fluid which includes alkali metal into the above-mentioned gap. Further, the dielectric layer is composed of a material having small activity with alkali metal.
