Abstract: A method for manufacturing a black matrix of a plasma display panel includes the steps of forming transparent electrodes of upper electrode patterns and black matrix patterns on an upper substrate, and depositing a predetermined metal material on the transparent electrodes of the black matrix patterns. In the method for manufacturing a black matrix of a plasma display panel, it is possible to manufacture the black matrix without performing a separate baking process. In addition, since it is possible to pattern the upper electrode and the black matrix at the same time, the manufacturing process steps are simplified and the manufacturing cost is saved.

Abstract: A cold cathode discharge device with high efficiency of light emission and long life is prepared by a cold cathode having both high secondary electron emission and anti-spattering property. Using carbon system cold cathodes constituted of a mixed phase of diamond and graphite, a cold cathode discharge device with high efficiency of light emission and long life is realized. It is desirable that an element having a wavelength of light emission equal to or shorter than 200 nanometers should be mixed in the discharge gas.
