A plasma display panel having an increased aperture ratio which improves luminous efficiency, and having increased discharge uniformity in a discharge space enhancing luminance, is composed of: a front substrate and a rear substrate separated from each other; barrier ribs interposed between the front substrate and the rear substrate to partition discharge cells; discharge electrodes separated from each other and disposed between the front substrate and the rear substrate to generate a discharge; and fluorescent layers formed in the discharge cells. Two or more discharge spaces are formed in each of the discharge cells. Since two or more discharge cells are formed in one discharge cell, discharge uniformity is increased in a discharge space, thereby improving luminance.
