Abstract:
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 of a 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 of an 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.
