Production manner of the hollow condition cathode and this hollow condition cathode for the display device which contains the plasma

摘要

(57) Abstract In order to improve the performance, reliability and life of the electric optical display device which includes the plasma, the hollow body or the well which plasma discharge occurs at least in the cathode electrode is provided. Because of this, in the wall of the device there is a tendency which the electrode material which spatter it should accumulate decreases. Furthermore, cathode emission, with whether alloy or either one whether surface coat of it improves being able to soak the emission material in the electrode by.
