Abstract
A plasma display panel for color displaying is provided which is so formed that it is possible to improve the contrast and color purity of the display panel while at the same time controlling the brightness drop to a minimum level. In particular, it is possible to effectively inhibit a contrast drop usually caused due to neon emission. In practice, an optical filter capable of attenuating light components each having a wavelength within a range of 560-590 nm is provided on the front side of the plasma display panel. Such plasma display panel includes an electric discharge space containing a discharge gas mainly comprising neon gas and xenon gas.
