Plasma display panel with bus electrodes having black electroconductive material

On a first substrate provided on a display surface of a plasma display panel, bus electrodes ( 12 a, 14 a) 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 (RuO2, etc.) by a screen printing. This prevents exter...

Summary:On a first substrate provided on a display surface of a plasma display panel, bus electrodes ( 12 a, 14 a) 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 (RuO2, 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 ( 12 a, 14 a) 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.
