摘要： In a plasma display device, a lighting percentage is calculated from a video signal inputted into the plasma display device, and such an output current of a DC-DC converter (140) as is equal to the discharge current for a maintenance period corresponding to that lighting percentage is fed in synchronism with the generation timing of the discharge current. With this configuration, a maintenance pulse voltage can be kept constant even if the discharge current for the maintenance period of each subfield abruptly varies.

摘要： There is provided a plasma display panel having a discharge cell in which a dielectric layer covering the electrode is covered with a protection layer, which faces a discharge space filled with a discharge gas. The discharge gas includes at least one of Xe and Kr. The protection layer has an electron level band including an electron of energy level having a depth within 4 eV from at least the vacuum level and formed in the forbidden band in the energy band.
