A plasma display panel comprises front plate (20) having display electrode (24) formed on a glass substrate with discharge gap (50), and back plate (30) having barrier ribs (34) formed to divide discharge cells, and arranged in a manner to confront the front plate (20). The barrier ribs (34) comprise vertical barrier rib (34a) arranged in parallel to an address electrode and horizontal barrier rib (34b) arranged in a manner to cross the vertical barrier rib (34a), and the vertical barrier rib (34a) has a shape satisfying the formula of H1>H2>H3, where H1 denotes a height of it at crossing portion (56) with the horizontal barrier rib (34b), H2 a height at a position of the discharge gap (50) of the display electrode (24), and H3 a height at a predetermined point between the position of the discharge gap (50) and the position of the crossing portion (56) with the horizontal barrier rib (34b).
