A PDP is proposed which has high emission efficiency and which can decrease address discharge voltage. In a column direction of at least one of transparent electrodes, which perform sustain dischargevia respective discharge gaps of a pair of row electrodes and constituting a row electrode pair, is set to 150 mum or less, and partial pressure of xenon in discharge gas sealed in a discharge space is set to 6.67 kPa or more. A width of a scan electrode, which is one row electrode of each of the row electrode pair facing the column electrode and to which scan pulse is applied, is wider than a width of the other row electrode of the pair to which discharge sustain voltage is applied.
