A plasma display panel includes a substrate, a dielectric layer formed on a top surface of the substrate, and partitions spaced a predetermined distance apart from each other and having a snaking or meandering shape. The partitions form channels having main discharge spaces and auxiliary discharge spaces alternately arranged and connected to each other. Red (R), green (G) and blue (B) phosphors are coated on the main discharge spaces in a triangular shape and where G and R phosphors are aligned with each other in a horizontal direction. The thicknesses of partitions forming the main discharge spaces where the R and G phosphors are coated are greater than thicknesses of the partitions forming the main discharge spaces where the B phosphor is coated.
