A plasma display panel is provided to lower total electrical capacitance and minimize leakage current due to a high dielectric constant by using an internal barrier rib having the high dielectric constant and an external barrier rib having a low dielectric constant. A rear substrate(111) is disposed opposite to a front substrate(101). A plurality of barrier ribs(112) are formed with internal barrier ribs and external barrier ribs in order to define discharge cells between the front and rear substrates. The internal and external barrier ribs have different dielectric constants. The dielectric constant of the external barrier rib is lower than the dielectric constant of the internal barrier rib.
