    Abstract: A gas discharge display panel for a large screen display in which the display brightness and emission efficiency are very high, the display accuracy is high, and is simple to construct. Cathode electrodes having openings forming discharge cells are arranged in parallel on a front plate and a number of anode electrodes are arranged in parallel on a rear plate orthogonal to the cathode electrodes. Each opening in the cathode electrodes may be rectangular, substantially rectangular or circular. The length of one side of a rectangular opening or the diameter of a circular opening is set to satisfy 40 lambda e

    Abstract: A plasma display panel with an electrode composed of a metal layer (e.g., Fe and Ni) and a metal compound layer (e.g., alkaline earth metal oxide or sulfide, and rare earth metal hexaborides) which are formed by means of plasma spray coating. The plasma spray coating should be done at such a temperature that the metal or metal compound is in the molten state.

    Abstract: PURPOSE:To reduce the operating voltage, and obtain a cathode with durability as well as enough physical strength by forming a metal or metal compound layer on a display panel base plate by plasma jet flame coating, and constituting an electrode by use of the said layer. CONSTITUTION:A wiring pattern for a cathode 4 is formed on a back glass plate 2 by subjecting a metal such as Ni, Fe or Cu to plasma jet flame coating. After that, an emitter 8 of, for example, 10-50mu thickness is provided at a cathode part, which forms an electric-discharge cell 5, by subjecting a metal having a small work function, such as Mg or a misch metal (an alloy consisting of La, Ce and Fe), to plasma jet flame coating. The cathode prepared by the above mentioned plasma jet flame coating can have enough durabilty, since metal powder is fused to the cathode and the cathode can have sufficient thickness. Besides, the operating voltage of a gas electric-discharge display panel can be decreased, and the function of the above display panel can be increased.
