Plasma display panel having different structures on display and non-display areas

A plasma display panel, comprising:

• a front substrate;
• a common electrode and a scan electrode arranged on a lower surface of the front substrate;
• a bus electrode electrically connected to the common electrode and the scan electrode;
• a front dielectric layer covering the common electrode, the scan electrode, and the bus electrode;
• a rear substrate facing the front substrate;
• an address electrode arranged on an upper surface of the rear substrate to cross the bus electrode;
• a barrier rib arranged between the front and rear substrates;
• and
• a phosphor layer arranged on a discharge space defined by the barrier rib;
• wherein the bus electrode includes a display unit bus electrode arranged on a display area that displays pixels and a non-display unit bus electrode arranged on a non-display area electrically connected to the display unit bus electrode and connected to an external terminal, and wherein the display unit bus electrode and the non-display unit bus electrode have different structures;
• wherein the display unit bus electrode includes a dual-layered structure of a first bus electrode and a second bus electrode arranged on the first bus electrode, the first bus electrode being arranged close to the front substrate than the second bus electrode;
• wherein the second bus electrode is wider than the first bus electrode;
• wherein the non-display unit bus electrode includes a single-layered structure electrically connected to the external terminal;
• and
• wherein an undercut portion c of the display unit bus electrode, an undercut portion e of the non-display unit bus electrode, a height d of the edge curl portion on the display unit bus electrode, and a height f of the edge curl portion on the non-display area satisfy the following:
• c>e, d>f
• 0.1 μm≦c≦25 μm, 0 μm≦e≦25 μm,
• 0.1 μm≦d≦15 μm, and 0 μm≦f≦10 μm.
