• a front substrate and a rear substrate facing each other;
• a plurality of barrier ribs between the front substrate and the rear substrate;
• a discharge generation unit that causes a plasma discharge in a discharge space;
• and
• a fluorescent layer that generates visible light due to discharge,
• wherein the rear substrate includes at least two rear substrate parts connected to each other, the at least two rear substrate parts comprising a metallic material and facing different portions of the front substrate,
• wherein a connection line is arranged between the at least two rear substrate parts, and
• wherein the front substrate and the rear substrate are separated from each other by a space in a region corresponding to the connection line.
