Abstract
A plasma display panel includes a first substrate, and a second substrate facing the first substrate. The first substrate includes a transparent substrate, a scanning electrode and a common electrode both formed on the transparent substrate, and a dielectric layer covering the transparent substrate, the scanning electrode and the common electrode therewith. The second substrate includes an electrically insulating substrate, data electrodes formed on the electrically insulating substrate, partition walls formed on the electrically insulating substrate, and a phosphor layer covering the electrically insulating substrate and the data electrodes therewith between adjacent partition walls. The phosphor layer includes a blue-phosphor layer composed of phosphor which emits a blue light. The blue-phosphor layer is 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.
