A plasma display panel comprising plural kinds of phosphor layers emitting different colors of fluorescent light, at least one kind of the phosphor layer being formed of a mixed phosphor obtained by mixing a phosphor having a surface potential with a negative polarity and a phosphor having a surface potential with a positive polarity. By using the mixed phosphor, the negative polarity of the surface potential is changed to the positive polarity, thereby reducing the discharge error and discharge variation, and improving the quality of display.
