Plasma display panel

A plasma display panel, comprising:

• a first substrate;
• a second substrate provided opposing the first substrate;
• a plurality of address electrodes formed on the first substrate along a first direction;
• a plurality of main barrier ribs mounted between the first substrate and the second substrate and defining a plurality of discharge cells formed into a plurality of rows along a second direction substantially perpendicular to the first direction;
• a plurality of non-discharge regions formed between the respective rows of the discharge cells;
• a plurality of transverse barrier ribs, each of the transverse barrier ribs extending along a distance of at least two of the discharge cells in the second direction and within the respective non-discharge regions;
• a plurality of phosphor layers, each of the phosphor layers being formed in a respective one of the discharge cells;
• and
• a plurality of display electrodes formed on the second substrate,
• wherein at least one end of each of the transverse barrier ribs includes an annular branched segment.
