Abstract:
A plasma display panel, comprising:front and rear substrates coupled to face each other;a partition formed between said front and rear substrates to define a discharge space;discharge means for generating ultraviolet (UV) parent light rays by a discharging gas filled in said discharge space;a fluorescent layer, formed in a predetermined pattern in said discharge space, for emitting light by being excited by said UV parent light rays;a reflection film, formed in an area where said fluorescent layer is not formed in said discharge space, for reflecting said UV parent light rays toward said fluorescent layer;wherein said reflection film is formed by superimposing at least two transparent thin film layers different from each other; andthe thickness of said thin film layers is set to (.lambda./4)n.+-..lambda./16, where .lambda. is the wavelength of said UV parent rays, and n equals number of said thin film layers.
