A plasma display panel includes a rear plate, a front plate parallel to and spaced apart from the rear plate, and a plurality of ribs between the plates to define a plurality of discharge space groups therebetween. Each discharge space group includes a first discharge space and a second discharge space. A first fluorescent layer is coated in the first discharge space and on a first side wall surface of the ribs surrounding the first discharge space, and a second fluorescent layer is coated in the second discharge space and on a second side wall surface of the ribs surrounding the second discharge space. A second thickness of the second fluorescent layer is larger than a first thickness of the first fluorescent layer so that the surface area of the first fluorescent layer is larger than the surface area of the second fluorescent layer.
