1. A plasma display panel comprising a first substrate facing a viewer, and a second substrate arranged in facing relation to said first substrate,said first substrate being comprised ofa transparent substrate;

  • a scanning electrode and a common electrode both formed on said transparent substrate in facing relation to said second substrate; and

    a dielectric layer covering said transparent substrate, said scanning electrode and said common electrode therewith,said second substrate being comprised ofan electrically insulating substrate;

    a plurality of data electrodes formed on said electrically insulating substrate;

    a plurality of partition walls formed on said electrically insulating substrate; and

    a phosphor layer covering said electrically insulating substrate and said data electrodes therewith between adjacent partition walls,said phosphor layer including at least a blue-phosphor layer composed of phosphor which emits a blue light,said blue-phosphor layer being composed of a mixture of two or more phosphors each of which emits a blue light and has an initial brightness and variation of brightness with the lapse of time both different from one another.
