Abstract
A plasma display panel for plasma display system provides excellent optical characteristics, including a color purity, contrast, and luminance, of a plasma display system. Barrier ribs forming a cell has wavelength-selective reflective filters for reflecting only a light of wavelength needed for display and absorbing the other lights coated thereon. The wavelength-selective reflective filters have phosphors coated thereon. A color filter is inserted between a first front panel and second front glass panel for feeding out the light in a sandwich state.
