PROBLEM TO BE SOLVED: To provide a gas discharge panel and a manufacturing method thereof which can be driven at a lower drive voltage than conventional devices, and which has excellent luminous efficiency. SOLUTION: A protective layer 242 comprising at least one of magnesium oxide, aluminum oxide, and spinel is produced by a method selected from among a plasma CVD method, a sputtering method, and an ion plating method while applying a negative bias voltage to a front panel 20, and in a crystal structure of the protective layer 242, oxygen defectives (F-centers) where two free electrons are trapped are formed.
