A plasma display panel includes a first substrate, a second substrate, and discharge gas filled in a space defined between the first and second substrates, the first substrate including at least one first electrode extending in a first direction, and at least one second electrode extending in parallel with the first electrode, the second substrate including at least one third electrode extending in a second direction perpendicular to the first direction, and a plurality of partition walls extending in the second direction for partitioning a display area, wherein at least one of the first and second electrodes is comprised of a first portion being in the form of a line extending in the first direction, and defining a discharge gap between itself and an adjacent electrode, and a second portion radially extending from the first portion in a direction away from the discharge gap.
