Abstract
A plasma display panel has front and back substrates, each in a warped state in which a central portion of the substrate projects forwardly relatively to a peripheral portion thereof, presenting a convex front surface, a stress produced in the front and rear substrates pressing the front and rear substrates together with an elastic deformation. A height difference ratio of a central portion, measured from a central part of a short side, of each substrate, divided by a longitudinal width of the substrate is preferably less than 0.1% for each of the substrates.
