A plasma display panel includes first and second transparent substrates provided opposing one another; first electrodes provided in parallel on the first transparent substrate, second electrodes provided in parallel on the second transparent substrate on a surface of the same opposing the first transparent substrate, the second electrodes being formed perpendicular to the first electrodes, and barrier ribs that form concave sections between the second electrodes and define discharge cells together with the concave sections. The second electrodes are formed by keeping still conductive liquid material that includes conductive particles, and allowing precipitated conductive particles to join by a heat treating process. In another aspect, at least one protrusion is formed in the each of the concave sections to divide the concave sections into a plurality of sections.
