PROBLEM TO BE SOLVED: To provide a PDP in which a high light-emitting efficiency can be obtained, and which has good exhaust characteristics of impure gas, and is improved in instability of discharge characteristics due to exhaust failure. SOLUTION: The plasma display panel is provided with a plurality of row electrode pairs which are constituted of row electrodes X1, Y1 mutually formed in opposed pair through discharge gap g1 arranged on the front substrate, a dielectric layer 12 to cover the row electrode pairs, and a plurality of column electrodes D1 which are arranged on the other substrate side and extend in column direction, and a discharge gas containing xenon is filled in the discharge space and unit light-emitting regions are respectively formed at a portion where the column electrodes and the row electrode pairs cross each other. The width Wx1, Wy1 in the column direction of the row electrodes is established at 150μm or less, and partial pressure of xenon in the discharge gas is established at 6.67 kPa or more. In order to demarcate the unit light-emitting regions between the substrates, barrier ribs 15 of lattice shape consisting of vertical wall parts 15B extending in column direction and horizontal wall parts 15A extending in row direction are formed, and the height of the horizontal wall parts is lower than that of the vertical wall parts.
