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.
