Plasma display panel for producing high color temperature white light and upper substrate thereof

A plasma display panel (PDP), comprising:

• a lower substrate, comprising:
• a first substrate;
• a plurality of data electrodes, disposed on the first substrate and extending in a first direction;
• a rib structure, disposed on the first substrate and covering the data electrodes;
• and
• a fluorescent layer, disposed on a surface of the rib structure;
• and
• an upper substrate disposed over the lower substrate, configuring a plurality of first, second, and third discharging spaces with the rib structure of the lower substrate, the upper substrate comprising:
• a second substrate;
• a plurality of bus electrodes, disposed on the second substrate, each of the bus electrodes comprising a plurality of electrode lines extending in a second direction perpendicular to the first direction and a plurality of connecting sessions to electrically connect the electrode lines, wherein the bus electrodes corresponding to respectively the first discharging spaces, the second discharging spaces and the third discharging spaces are different in structure, so that the luminance generated by the first discharging spaces, the second discharging spaces and the third discharging spaces are different from each other;
• and
• a plurality of straddle lines, disposed between two of the electrode lines of respectively the first discharging spaces and the second discharging spaces and straddling at least one of the electrode lines in the first direction, wherein the straddle lines disposed in the first discharging spaces have a linewidth different from the linewidth of the straddle lines disposed in the second discharging spaces in the second direction.
