A plasma display panel that shortens the delay time of an address discharge by providing an exoelectron emission layer on a protective layer is disclosed. The plasma display panel includes first and second substrates facing each other and spaced apart from each other, barrier ribs arranged between the first and second substrates and defining discharge cells, phosphor layers formed within the discharge cells; address electrodes formed on the first substrate and extending along a first direction, first and second electrodes formed on the second substrate and extending along the second direction, a protective layer formed in a discharge region of the discharge cells, and an exoelectron emission layer formed outside the discharge region.
