Abstract: On a first substrate provided on a display surface of a plasma display panel, bus electrodes (12a, 14a) in X and Y electrode lines (12, 14) forming a pair of display electrode lines are formed with an Ag material containing a black additive (RuO.sub.2, etc.) by a screen printing. This prevents external light from being reflected at the surfaces of the bus electrodes (12a, 14a) on the display side of an FP substrate (10) to improve the display contrast. The bus electrodes (12a, 14a) may be formed as a multi-layer structure. In this case, for example, the lower-layer bus electrodes are formed with a black metal material and the upper-layer bus electrodes are formed with a light-reflecting material layer, which improves light utilization efficiency and further improves the contrast.

When a voltage greater than or equal to the Paschen minimum firing voltage is applied across the cavity at a crosspoint, a plasma is created. Ions in the plasma spread from the cavity into the tube in response to a voltage that is applied to the cover plate.
