An alternating current driven type plasma display device which does not increase a driving voltage (discharge voltage) and does not increase a time delay of discharge is provided. The alternating current driven type plasma display device contains a first panel having a plurality of first electrodes formed on a first substrate and a dielectric layer formed on the first substrate and the first electrodes and a second panel, in which the first panel and the second panel are bonded to each other in circumferential portions thereof, the dielectric layer is constituted by SiO.sub.X, and bonding density of H.sub.2O contained in SiO.sub.X is 3.0.times.10.sup.20 Bonds/cm.sup.3 or more.
