A plasma display panel includes a first substrate, and a second substrate
opposing the first substrate. A plurality of address electrodes are
formed on the first substrate along a first direction, and a plurality of
barrier ribs are mounted between the first and second substrates and
defining a plurality of discharge cells that are formed into a plurality
of rows along a second direction which is substantially perpendicular to
the first direction. Non-discharge regions are formed between the
respective rows of the discharge cells, and a plurality of transverse
barrier ribs are formed along the second direction respectively within
the non-discharge regions. Each of a plurality of phosphor layers is
formed in a respective one of the discharge cells. Display electrodes are
formed on the second substrate. At least one end of each of the
transverse barrier ribs includes an annular branched segment.
