Patent ID: 7211952

Claim:
A gas discharge display device using a plasma display panel, comprising: a plurality of discharge cells formed within a discharge space between a front substrate and a rear substrate, each of the discharge cells including a discharge gas therein and being provided with one of fluorescent substances of red, green and blue selected to emit light for performing color display, whereby at least some of the plurality of discharge cells are provided with the red fluorescent substance, at least some of the plurality of discharge cells are provided with the blue fluorescent substance, and at least some of the plurality of discharge cells are provided with the green fluorescent substance; and a filter disposed apart from the front substrate, the filter having a characteristic of attenuating light within a wave range of visible light emitted by the discharge gas, wherein a light-emission intensity of at least one of the fluorescent substances of red, green and blue is set to be larger than would be necessary to display an intended white color by simultaneous unfiltered light emission of the fluorescent substances of red, green and blue, so that light within the wave range is emitted with intensity to compensate for attenuation of light within the wave range attenuated by the filter.
