A plasma display panel has an image display region(17)and a non-image display region formed by facing front glass substrate (3) to back glass substrate (10), and has a sealed part (18) formed by sealing peripheries of the glass substrates in the non-image display region with a seal layer(19). A thickness of at least one of the front glass substrate (3) and the back glass substrate (10) is 2.0 mm or less, and an interval between the glass substrates in the sealed part longer than an interval between the glass substrates in the image display region.
